How do you obtain a migration license for Cisco Unity Express 7.x?


Follow these steps to obtain a migration license for your existing Cisco Unity Express 7.1 features:
  1. Go to the licensing portal at www.cisco.com/go/license and click the link at the bottom of the page to go to the license migration portal.
  2. On the router that is running the features that you want to migrate, enter the show inventory command to see the corresponding product IDs and serial numbers.
  3. Enter the appropriate product ID and the serial number and click Continue. The product ID is the type of Network Module that you are using, such as AIM-CUE.
  4. Use the drop-down menus to select the product family, product, and feature (SKU), then click Continue. For the product, use the SKU that you determined in the previous section for the features that you want to migrate. Enter your registration information, including your company's name and e-mail address, then click Continue.
  5. Verify all of your license information and click Submit to receive the free CSL upgrade license file by e-mail.
  6. Repeat the appropriate steps above for each device that is running features that you want to migrate.
  7. Copy the license file(s) to a FTP or TFTP server. applications will be disabled due to the lack of available ports. The show license status application command will indicate this condition by stating the error message "voicemail disabled, ivr session quantity (x) is equal to or exceeds available ports (Y)" where X is the number of IVR sessions and Y is the number of ports. To change this condition, either reduce the number of IVR sessions via the command license activate ivr sessions N (where N is less than the number of ports and may be zero to deactivate all IVR sessions), or remove the IVR session licenses, or add more port licenses, and then issue the reload command.

Upgrade Cisco Unity Express from 3.x to 7.1.x. Cannot activate licenses


We have successfully upgraded a Cisco unity express (AIM-CUE) from 3.x to 7.1.x, however it now asks for the upload of software licenses. We have already uploaded the Mail-Box Licenses and IVR licenses, but the unit reports it cannot activate them since it has no port licenses, do these licenses have to be purchased separately or do they come with the AIM-CUE , if so how can we reactivate them.

Each IVR session consumes one port and thus reduces the number of ports available for use by voicemail or auto-attendant applications. Please carefully consider how many IVR session licenses you need and only install or activate licenses for that number of IVR sessions.
If the number of IVR session licenses is greater than or equal to the number of ports, then voicemail and auto-attendant applications will be disabled due to the lack of available ports. The show license status application command will indicate this condition by stating the error message "voicemail disabled, ivr session quantity (x) is equal to or exceeds available ports (Y)" where X is the number of IVR sessions and Y is the number of ports. To change this condition, either reduce the number of IVR sessions via the command license activate ivr sessions N (where N is less than the number of ports and may be zero to deactivate all IVR sessions), or remove the IVR session licenses, or add more port licenses, and then issue the reload command.

Unable to console into Catalyst 4507


We have some strange problem while trying to use the console to configure Catalyst 4507, We are using rollover cable, normal serial setting (9600-8-none-1-none). Switch has 2 supervisor engines ( Supervisor II-Plus).

The problem is that, we can see everything on the console, normal booting sequence, IOS image decompression, all messages that show normal synchronization with the other supervisor engine. Then when it reaches the part when it says Press Enter to start, we can’t type anything, we still can see all the messages (like when we pull the other supervisor engine out) it gives us the message that it was pulled out, yet we can’t type anything. Same thing with the second sup-engine. Unfortunately, Telnet and Aux port are not set, so they are unusable.

Diagnostic Steps
  1. A connector in the console port on the switch could be bent and not making contact. Make sure that the connectors inside the console port and make sure they all look good. Also try using a different PC.
  2. Force a redundancy to swap the connection onto the secondary supervisor module ? make sure you have ACTIVE status on module 2 when you do this.. and module 1 becomes standby... check console connectivity on module 2... with Sup II plus, you would just have a single console and single iP address available for management , so you need to check.... you can reboot the primary SUP, to make it secondary (manually),.. you can also do "redundancy reload peer" to reload the secondary supervisor (not reqd in this case)
Another Option

  1. Get any Cisco router however old or new. 2500 will do, and so will 7206. What you need is a router with an aux port. So it needs to be a software router, which have aux ports.
  2. Connect AUX port of the router to a CON port on the 4500
  3. Login with a console or whatever to the router.
  4. Look at the number of the aux port via "show line"
  5. Add this number to 2000. E.g. if the AUX is line 33, the result will be 2033
  6. Do a reverse telnet:
conf t
int loop 0
ip add 10.0.0.1 255.255.255.255
end
telnet 10.0.0.1 2033

Attendant Console Plug-in does not show up in CUCM 7


We have activated the Console Attendant Service from System service parameters and our version of UCM is 7.1.2.21900-5. When we go to Application Plug-ins we don't see the Attendant Console plug-in to download to the desktop. Can someone explain why this is the case?

AC plugin is version specific, you cannot mix an AC from 5.x/6.x with CUCM 7. That goes for the exact release as well ie 7.0 does not mix with 7.1. That scenario is NOT supported.

If you had the AC working and configured before the upgrade and used DMA or you upgrade from a Linux version the plugin should be there.

Please click here for more information on Attendant Console Plug-in.

CUCM 7.1(3) TFTP Auth Fail error


Since upgrading to CUCM 7.1.3.10000-11 any new phone plugged into the system gets an "auth fail" from the TFTP server when attempting to upgrade the firmware to the version that comes with 7.1(3). Phones that were registered prior to the upgrade work just fine. We are seeing the same behavior on the non-production environment which is also at 7.1.3-10000-11. Phone Firmware for 7.1(3) on 7961G set is SCCP41.8-5-2SR1S

The Cisco phones that are currently shipping (as of January 27, 2010) with 8.3(2) but must be upgraded to a firmware load greater than or equal to 8.3(3) up to a load less than or equal to 8.5(2) prior to upgrading to 8.5(3). This is an issue for new phones mostly - the default manufacturing load has to be 8.3(3). The process for doing so involves testing in manufacturing as well as a control run test build. For recently shipped phones, the process specified in the 8.5(3) release notes is the correct process to follow.

Here is the reason as to why this issue happened. Cisco firmware is signed to ensure that only Cisco-certified firmware may be loaded on our phones. It was necessary to upgrade the servers that do the signing and the loads that understand both signing keys are, not surprisingly 8.3(3) though 8.5(2). The old servers were decommissioned and no longer available so 8.5(3) only understands the new server signing keys, hence the need to upgrade first to a load that understands both keys.

Alternatively you can try this workaround
  1. download firmware 8.4(4) in ZIP format from cisco.com (cmterm-7945_7965-sccp.8-4-4.zip)
  2. extract a zip file to tftp server on my laptop. i use 3CDaemon for tftp server.
  3. change the dhcp value for option 150 to tftp's ip .
  4. reset the ip phone to factory default by pressing hold# and then 123456789*0# (http://www.cisco.com/en/US/products/hw/phones/ps379/products_tech_note09186a00800941bb.shtml)
  5. ip phone will retrieve firmware v.8.4(4) from my laptop.
  6. when downloading the modified image file finished, change the dhcp value for option 150 to cucm's ip.
  7. register 7945G with cucm and "Auth Fail" should not appear.

Problem with ACE4710 in L2 mode. It does not pass traffic between VLANs.


We have ACE4710 appliance from Cisco. We configured RDP load balance in bridge mode, but ACE doesn't pass traffic between the VLANs. ICMP req and rep passed. We can ping VIP and some of servers in server farm, but can't establish RDP session to VIP or directly to servers. ACE4710 work in bridge mode. Interface Vlan 501 and 1501 are members of bridge group 1.

Diagnostic steps

1) Server response could be bypassing ACE (asymmetrical traffic). Try configuring
Source NAT if it resolves this issue.
Click here for more information on sample config on how to configure Source NAT on ACE.

2) Please check and confirm that the servers are in VLAN 501 and the upstream router is in VLAN 1501.
3) Please check and confirm that the default gw of the server is the upstream router in VLAN 1501.
4) Try to only match on the VIP address (remove the "tcp eq rdp").
5) Check if you are able to initiate a RDP session directly on the server, through the ACE but on the IP of the server.
6) Check your HP NIC Teaming software on blade servers. If Teaming mode Auto/Auto traffic does not correctly return to ACE then change the mode to Network Fault Tolerance Only (only one NIC active) and try again.

Cisco 4500 switch goes into a reboot loop


Whenever we power up the 4500, it goes to ROMMON and sits there until we manually type in "boot" and hit enter. After the manual boot, everything seems to work fine. This switch hasn't been used for awhile so we are not sure what/who caused this to happen. Since it does boot, we know the image is there and OK. We have tried running boot system flash cat4500-ipbase-mz.122-31.SGA6.bin command multiple times but it keeps booting into ROMMON mode.

Diagnostic Steps

1) Current BOOT file is --- flash:cat4500-ipbase-mz.122-31.SGA6.bin
Invalid filename flash:cat4500-ipbase-mz.122-31.SGA6.bin. It must begin with device name.
It cannot find the file you specified for it to use in bootup and therefore it goes to ROMMON.
Where is the image actually stored ?
Try the following commands to get further details
post the current boot system command ie."sh run | include boot system"
post the output of "dir /all" from the switch.


2) sh run | include boot system
boot system flash:cat4500-ipbase-mz.122-31.SGA6.bin
You have boot system flash:xxxxxx
If your image is in bootflash, you need to do a boot system flash bootflash: and then your image name.

3) Make sure you have the right boot-system commands configured, or if it is only one IOS which is on the bootflash, you can remove the boot-system commands to make sure it boots the ONLY IOS on the bootflash.. do a "no boot-system bootflash: xxxx " to remove this.

4) If you have these commands, can you remove them
and just have one command with booting the sytem from bootflash

boot system flash
boot system flash:cat4500-ipbase-mz.122-31.SGA6.bin

Timezone in Cisco ip phones does not update



We installed CUCM-BE 7.13 in place with 7941s throughout. The time on the phone is not correct, although in my Time/Date field on CUCM is configured correctly. The CUCM specifies the correct timezone and time on the server appears to be correct.


We can change the phone's date/time format, but not the timezone. Any suggestions?

Upgrade to 7.1.3b. Then change to a timezone with * and it should reset from Date/time group page itself.
Check the phones - they should immediately reflect the correct time zone.

Is there a Windows 7 x64 driver for Quickcam Pro 5000 Cisco VT camera II?


There is an unsupported workaround for this.

We have tried it and it works but it doesn't let the video advantage work with anything except an IP Communicator. The solution is as follows -

1) Please click here to download the latest driver from Logitech's website for Vista x64 for the QCP 5000.
2) From a non-Windows 7 PC (or from XP Mode), run the installer. Let it extract all of the files, and DO NOT PROCEED through the installation process (or if it errors, keep the error message open). Go to the Temp folder where the files were extracted (in our case, in XP Mode, it was C:\Documents and Settings\{username}\Local Settings\Temp\QuickCam_11.1.0) COPY (don't Move) this folder to a location that's accessible to your Windows 7 system.
3a) For Cisco VT users, go into the \QuickCam_11.1.0\Drivers\x64\PRO464 folder and edit the lPRO464v.inf file. Do a find-and-replace, finding 08C5 and replacing it with 08C7 (this essentially makes the inf file identify your Cisco VT device ID as a QCP 5000). There could be as much as 85 replacements that you will have to do. Save and close the ini file.
3b) Go into Devices and Printers. Go into the properties for the USB Composite Device, find the Unknown Composite Device, and update the driver. Select to manually specify the driver location. Point it to the \QuickCam_11.1.0\Drivers\x64\PRO464 folder, and you should be all set.

“Cannot enable port security on a trunk” error. How to setup port security on a trunk port 2950?


We are using a 3550 switch. When we try to enable port security, the command is rejected "you cannot enable port security on a trunk" is the message. We are trying to enable security on a switch that has both data and voice VLANs configured. In the docs it indicates that you cannot have port security on a trunk port. We are wondering if this was absolutely true as we would like to secure some of our ip phone switch ports that are trunk ports.

Diagnostic Steps
1. When you enable port security on an interface that is also configured with a voice VLAN, you must set the maximum allowed secure addresses on the port to at least two secure addresses. If any type of port security is enabled on the access VLAN, dynamic port security is automatically enabled on the voice VLAN. You cannot configure port security on a per-VLAN basis

2. On a Cisco 3550, you can use the "switchport voice vlan" command along with the "switchport access vlan" command to separate the voice and data traffic without having to use a trunk. This would, however, depend on the phone you are using. Then, since the port would be an access port, you could apply port-security to it.

3. When you connect IP Phones to switch and configure voice vlan command it internally forms a trunk so no special trunk configuration in required.
Please click here for more information.

4. Cisco does not allow you to configure port security in trunk ports cause trunk ports may learn many mac addresses which will defeat the use of port security feature so when you connect ip phones and want port security feature so not configuer ports as trunk and instaed configure as voice vlan for voice traffic and also configuer the same port with access vlan for data traffic.

5. By default, all the ports are in the vlan 1 thats why its not shown in the configuration. even you configure it for VLAN 1. If you configure the port for another VLAN, it will show up in the configuration.

6. Avaya phones do not require an explicit dot1q trunk. You can try this configuration
interface FastEthernet0/2
description to IP phone and PC
switchport access vlan 2
switchport voice vlan 3
mls qos vlan-based
no cdp enable
spanning-tree portfast

7. For Mitel 3300 phone systems with Mitel 5330 IP Phones try the following –
interface FastEthernet0/30
switchport mode access
switchport voice vlan 10
switchport port-security
switchport port-security maximum 2
switchport port-security mac-address sticky
spanning-tree portfast

8. Also this configuration will be useful using trunk port with port security
int fax/x
switchport mode trunk
switchport port-security
switchport port-security mximum 2
switchport port-security mximum 1 vlan 5
switchport port-security mximum 1 vlan 1
If you have trunk with vlan 1 and 5 this configuration will make the max mac address to 2 and 1 per VLAN as well

Failed to get the JTAPI Provider; JTAPI fails


When we migrated our CER to 7.1(1) the JTAPI started failing? How do we resolve the issue.

Diagnostic Steps
  1. Confirm that all the servers are reachable from CER and vice-versa
  2. Make sure that CTI Manager service is started on the servers
  3. Confirm that the username and pass you use for the jtapi user that get assigned to CTI route point is configured correctly on CER and CUCM. (try not to use any special characters in the username or pass)
  4. If CTI Manager service is already started on CUCM, restart it.
  5. Check and verify if there is a version mismatch between the JTAPI provider on the UCM and CER servers. If there is a mismatch downgrade the CUCM version under the Admin Utility from 7.1 to 7.0. The JTAPI started working again.

How do you migrate from CCM 4.1 to CUCM 7.1

Steps for Migration
  1. First, make sure you have the necessary new servers and install a fresh copy of UCM 7.1.
  2. Then work with Cisco licensing to get the DLU files created. Send them a list of all the phones and MAC addresses as well as which service contracts the servers were under.
  3. They will then create a file and sent it to you to load into the UCM 7.1 cluster.
  4. Build an intercluster trunk between the 2 clusters so users could still communicate with each other while we completed the different phases of the migration. Please click here to find more information on setting up intercluster trunks
  5. Next, build fresh partitions, CSS, dial patterns and other system features on UCM 7. This is important if you need to change your naming convention and make it more standardized. There are also a lot of new features around paritions and CSS that you can take advantage of.
  6. Next export your phone configs from CM 4 and put them in BAT files. This can be imported into UCM 7.
  7. Then make changes to your DHCP scopes to change the TFTP entries so that you just need to reboot the phones in CM 4 for them to then come up in UCM 7.
  8. If you run the issue of not being able to bulk change the voicemail integration in Unity 5, you can do it in the SQL database itself.

CCM Failed to upgrade 7.x after importing data with disaster recovery


Diagnostic Steps
  1. This is because the locale wasn't import with the disaster recovery that I did before the upgrade. Locale files are not import after a disaster recovery, if we try to upgrade to another CCM version it will show this error.
  2. If you have an actual 5.1.3 and you want to install a new in parallel you will need to install the locale before going to 7. For example if you have 5.1.3 in production ,install 5.x locale and then upgrade to 7
  3. Also if you have done a restore of the data and all user are using the French locale which is not part of CCM by default the upgrade will fail. CCM will not be able to do the upgrade because all user are set to the French locale but the locale isn’t there.
  4. Prior to upgrade install 5.X locale on the existing server, do the DRF backup. Load the new server with all the specific information (name, ip address and so forth). Once it is on the wire do a restore from the backup on to the new server.

7915 expansion modules not displaying anything


We are working with CME version 7, 7962 ip phone which has 7915 expansion modules. The modules are ok, but they don’t display any data next to the buttons. However if you press the any of the buttons, the call goes through. But on the modules, nothing can be seen. How do we resolve this issue?

Diagnostic Steps
1. Instead of upgrading to 8.5 load try to upgrade gradually. From your current version downgrade to 8.3 load, upgrade to 8.4.2, then up to 8.5 load.
2. For all SCCP firmware upgrades from firmware release versions earlier than 8.3(3) to version 8.5(2)SR1 or greater, first upgrade your firmware to version 8.5(2). Once you have upgraded to version 8.5(2), you can upgrade your IP Phone to version 8.5(2)SR1 or later.
3. So we need to downgrade our firmware to first 8.5(2) the we can proceed with our upgrade to 8.5(2)SR1 or later, this issue as there is a mismatch in the signatures between the firmware loads, hence resulting in the 7915 screens being blank.

Warning: monitor nvram area is corrupt


We got the error message as below while loading the 3660 router. Warning: monitor nvram area is corrupt ... using default values. ERROR in NVRAM sizing. NVRAM could be bad! What could be the cause of this problem?

  1. The router is probably experiencing a hardware problem. The problem also encompasses the FLASH memory, as the router is not able to access it and load the IOS stored there.
  2. Enter the ROMMON mode and try to download the IOS file back to the FLASH using the tftpdnld command. The following URL contains a discussion how to use this command. It is written for 2600 series routers but will work the same way for 3660.
  3. If you manage to load and boot the IOS, try to issue the commands erase startup-config and copy running-config startup-config to reinitialize the NVRAM and to store data there.

Advantages of ip routecache on 2950t switch


The ip route-cache command is used on devices that perform routing to activate a so-called route cache (or Fast Switching) that speeds up the routing process by storing the result of routing table lookup in a cache, thereby improving the lookup time for subsequent packets going the same way. To deactivate the route cache on an interface, the no ip route-cache command is used.

The Catalyst 2950T does not have routing capabilities. The command no ip route-cache on the Vlan interface is there actually because the IOS is not performing any routing operations nor it has the support for that. The command cannot be removed from the Vlan interface. Simply put, it is a fixed command that results from the way the IOS for the 2950 series is built.

Click here for more information on Fast Switching and other switching methods here.

The primary function of a route cache is to speed up the routing table lookup by storing the result of the routing and header rewrite lookup for a packet into a cache organized for very fast lookups. For all subsequent packets going to the same destination, the results from the cache are used instead of looking them up again and again in the routing table and in the Layer3-to-Layer2 mapping tables, such as ARP or IP/DLCI maps. The load balancing may or may not be involved, and the per-destination load balancing is only a side effect of using the route cache.

IP phone showing "auth fail" error on screen. Issues with CUCM 7.0


We have installed cucm7.0 (ccmpub and sub)..when the ip phone 7970 registers with the ccmpub it shows "SCCP70.8-5-2SRIS" "auth fail" and "local authentication failed: SCCP70.8-5-2SRIS" error before registering to the ccmpub server. But when we remove the network cable from ccmpub it fail over to the second ccmserver (sub) but gives about error continuously after 2~3 minutes of gap..i chose unsecure mode in device security...do we have to change the firmware?

The phone firmware needs to be @ 8.5.2 before trying to go to 8.5.2sr1. For all SCCP firmware upgrades from firmware release versions earlier than 8.3(3) to version 8.5(2)SR1 or greater, you must first upgrade your firmware to version 8.5(2). Once you have upgraded to version 8.5(2), you can upgrade your IP Phone to version 8.5(2)SR1 or later. Click here for more details.

If you do not have the 8.5.2SR1 on the inactive version, revert UCM back onto the "Inactive Version". Install 8.5.2 (NOT 8.5.2SR1), this will upgrade the phones to 8.5.2, then switch partitions again, this should in tern upgrade to what every Firmware version you have.

%DUAL-5-NBRCHANGE: IP-EIGRP(0) 1: Neighbor 10.5.109.3 (Vlan109) is down: retry limit exceeded & peer restarted


We are facing EIGRP neibor peer restarted error logs on my backbone switch and its getting down after every 4 hrs. All our network is severely being impacted due to this EIGRP neibour error.

Debugging Steps
  1. the failure of IP routing protocols and messages of duplicated addresses in HSRP are symptoms of underlying layer 2 problems.
  2. analyze STP and log on all devices. Be aware that also a malfunctioning or mis-configured access layer switch can be the root cause of this kind of problems.
  3. verify who is the root bridge for each defined vlan, there are chances that for some specific vlan the root bridge is a poor access layer switch.
  4. Starting from distribution or core switches you should use: show spanning-tree summary
  5. for each vlan listed in the previous show you can see details using: sh spanning-tree vlan vlan#
  6. Verify the root bridge id for each vlan. It should be one of core/distribution switches, if not this can be a problem.
  7. verify to the check if there is any wrong configuration that caused an access layer switch to be root bridge for a specific vlan.
  8. Try to reach by telnet each access layer switch. The log can be examined using: sh log
  9. search for spanning-tree messages if present they are a lot one for each vlan/STP instance.
  10. HSRP and routing protocols are like user traffic in this case and the error events are symptoms, changing the VIP address is not a solution.
  11. Also look for possible CDP native vlan mismatch that can join two vlans on access ports (no trunking)
  12. Since in your case the problem affects multiple vlans so the cause should be one of the previously mentioned (wrong root bridge or malfunctioning device)

Does 7600-ES+4TG3CXL require particular slot in 7600?


Does the 7600-ES+4TG3CXL need to be put on a particular slot like the RSP (e.g. slot 5 or 6 on 7606)? Does this has anything to do with the pin length at the backplane of the chassis? There's some length difference between the pin on slot 2 and the rest (on 7606). Slot no 2 seems to have longer pin.


Slots 1 and 2 are the ones to be used with supervisors 1A or 2. Sup 720 has to be installed in slot 5 or slot 6.

The reason for this is that Sup720 integrates the switching fabric SFM (actually a 720 Gbps matrix) that it is not present in older supervisors but existed as a separated line card to be installed in slots (5 and/or 6 only sup2 supports SFM). Click here for more details.

The Switch Fabric Module 2 (WS-X6500-SFM2) can be installed in any Cisco 7600 series router. (Click here and see Figure 11-2.) The Switch Fabric Module 2 requires Supervisor Engine 2 and must be installed in slot 5 or slot 6 of the Cisco 7606, Cisco 7609, or OSR-7609 routers, or in slot 7 or slot 8 of the Cisco 7613 router.

In conclusion, slot 1 and 2 have different pinout than the other slot because it was needed to host SUP2. SUP2 does not have integrated switch fabric, so install it separately from the supervisor (the SFM which installed on slot 5 or 6). Newer supervisors have the switch fabric integrated, therefore, those later version of supervisors need to be installed on slot 5 or 6.
