What are the steps to migrate from UCM Business Edition 6.1 to full UC 7.1.2 on 3 servers?

Steps for migration
  1. Upgrade BE to 7.1.2. Then, using the hardware replacement guide for UCM and Unity Connection, build a new UCM publisher and Unity Cxn both w/ the IP address of the current server. Then do a disaster backup of UCM and Unity and restore them to their respective servers. Do this will be on a separate network of course.
  2. Change the IP addresses of Unity Cxn and UCM Publisher for their new segment.
  3. Install the servers in their new location and swing DHCP to the new cluster.
  4. Wait for a few days for the system to stabilize. Re-install the current UCMBE server as subscriber 1 in the new cluster and shift the phones accordingly.

Please note that you will not be able to restore data back onto the CM and CX server separately. When you run DRS on the CUCMBE, it will spit out files which will be used by both CM and CX.

You can reuse the 7828 server for the Unified CM. It will support 1000 phones.

Can we combine 2 interfaces on same Cisco router


Can we combine 2 interfaces on same router for redundancy purpose, like we do port channelling on switch? For redundancy on 2 layer3 device we can use routing protocols like HSRP,VRRP, etc., Is there any way we can use 2 interfaces on router to assign a single ip address, so that if 1 interface fails traffic will be forwarded through other interface?

In addition to device-level failover, we can also configure interface redundancy on the same chassis of a Cisco ASA firewall. Basically you create a logical interface pair bundle (called “interface redundant“) in which you include two physical interfaces. If one of the interfaces fail, the second one in the redundancy pair takes over and starts passing traffic. You can
configure up to 8 redundant interface pairs. After you configure the redundant interface pair, all security appliance configuration refers to this logical redundant pair instead of the member physical interfaces.
Configuration Example:
ASA(config)# interface redundant 1
ASA(config-if)# member-interface gigabitethernet 0/0
ASA(config-if)# member-interface gigabitethernet 0/1
From now on, all interface related commands must refer to “interface redundant 1“.

Also you can have L3 etherchannels for ethernet family of interface. Please click here for more information on Fast EtherChannel Enhancements on Cisco 7200 Series Routers.

There is a new Feature on the ISR-G2 29xx and 39xx which have dual-purpose GE-Interface

interface gig 0/1
media-type sfp
media-type sfp auto-failover
So the SFP of gig0/1 is the primary interface the RJ45 of the gig0/1 is the Backup-Interface.
So you do not have any need to configure BVI Interfaces.

How do you add certificates between CUCM 6.1 and Exchange?


We need to add the secured SIP trunk between CUCM & Exchange server. Since CUCM needs to trust the Exchange server we need to add certificates to the CUCM. Can someone help us with this?

Please follow the following steps to add certs using the CM Platform, aka OS Administration web GUI. Once logged in, it's Security > Certificate Management > Upload Certificate.

The certificates you see uploaded are created during CUCM installation. They are the various self-signed certs for the components of the CUCM sub-systems. On the Exchange side, you will need the root CA certificate which can be either self-signed (customer has their own CA) or from a 3rd-party.

Edge wae is not registering with the central manager. WAAS CMS error


The edge wae can ping the central manager's ip address and even complete a trace route to the CM at three hops.

The error is as follows:
register: Registration failed.
cms: unable to register node
FAILED to enable management services.

De-register cms on the central manager, de-register the core WAE, and re-enabling cms on the central manager, core and edge WAEs. I hope This will resolve your issue.

If the above does not work then try a reboot of the WAE to solve the problem.

Can we use external music source for MoH on CUCM 7.1?


We have just installed Call Manager 7.1 and would like to use an external music source that we pay for as our music on hold. Is this possible? If so, how do we get the audio onto the call manager? We were not sure if we could add and audio card to the call manager server or if an external server is needed.
All you will need is a USB Audio adapter, part # MOH-USB-AUDIO= that hooks up to server via USB and lets you plug in a 3.5mm audio source into the USB box as a audio feed.

If recorded or live audio is needed, MoH can be generated from a fixed source. For this type of MoH, a sound card is required. The fixed audio source is connected to the audio input of the local sound card.
This mechanism enables you to use radios, CD players, or any other compatible sound source. The stream from the fixed audio source is transcoded in real-time to support the codec that was configured through Unified CM Administration. The fixed audio source can be transcoded into G.711 (A-law or mu-law), G.729 Annex A, and Wideband, and it is the only audio source that is transcoded in real-time.
The Cisco MoH USB audio sound card (MOH-USB-AUDIO=) must be used for connecting a fixed or live audio source to the MoH server. This USB sound card is compatible with all MCS platforms supporting Cisco Unified CM 6.x and later releases.

Please click here for more information on configuring Fixed and Audio file MoH services.

How do you edit the line text field for all the users in CUCM 6.1.4?


You can export your devices from BAT and then edit the line appearances in the exported .csv file. Then you can re-import the records into the phones. Make sure you check the box that says "overwrite existing".

A summary of procedure:
  1. Use BAT to Export Phones - All Details (you can do this by phone model or all models)
  2. Edit the CSV that is exported. Remove any phone records you aren't planning to update
  3. Edit the CSV that is exported. Modify the line appearances on the phones as per your requirement
  4. After editing the CSV, upload it to CUCM using BAT>Upload/Download Files (target: phones, transaction-type: phones-all details)
  5. Use BAT Phones>Insert to import the All Details record you uploaded. Check the box to overwrite existing record.
Please click here for more information on BAT administration.

CUCME: Blackberry, Iphone, Nokia E-series integration


How do you integrate Blackberry, Iphone and Nokia E-series for CUCME? Does it do the same as with CUCM?

CME does not support Cisco CUMA.
Consequently you can only use Iphone in SIP mode. Nokia also has SCCP client.

How do you obtain a migration license for your existing Cisco Unity Express 7.1 features?


There is no cost to obtain migration licenses for CSL.

Step 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.
Step 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.
Step 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.
Step 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.
Step 5 Verify all of your license information and click Submit to receive the free CSL upgrade license file by e-mail.
Step 6 Repeat the appropriate steps above for each device that is running features that you want to migrate.
Step 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.

Cisco 4507 - Loading new image upon reboot


We have a 4507RE and just copied over a new IOS (cat4500-ipbase-mz.122-31.SGA11.bin). Since the older image is currently loaded, we need to reboot the switch so that the new image can be loaded. What command can we use to instruct the switch to use the new image and not old upon reboot? But we do not want to erase the old image just in case we need to revert back to it.

conf t
no boot system
boot system bootflash:cat4500-ipbase-mz.122-31.SGA11.bin
boot system bootflash:cat4500-ipbase-mz.122-31.SGA6.bin
end
wr
reload
Basically, the commands mean boot SGA11 first. If the IOS fails, boot SGA6.

Is there a limit on the number of GRE tunnels that can be configured on a router?


There may be factors such as memory constraints that will place practical limits on how many tunnels you can support. But there is also a hard limit on the number of tunnels that you can configure. That limit is based on the limitation of the number of IDBs supported by your router. The IDB is the Interface Descriptor Block and each interface (physical, or tunnel, or loopback, or whatever) requires an IDB. The number of IDBs will vary by platform and sometimes by release level of the code that you are running. You can use the privileged command show idb to see what the limitation is on your router. On the 1841 router that I just checked the limit on IDB is 1200 (which is a pretty large number - I believe that you would encounter other limits on performance or on size of configuration before you exhaust the IDB limit).

Can different 3750 models be stacked?


We have 3750G-24 TS and a 3750-24TS (non-gig). Can we stack those two different kind of models? Never done it before and it seems it would be odd since it would be 24 gig ports and 24 FE ports. How about the code? Do they run the same code?

A Cisco 3750 switch can be stacked with any other model of Cisco 3750 switches. Catalyst 3750 switches that run Cisco IOS® Release 12.2(25)SEB are compatible with Cisco EtherSwitch service modules that run Cisco IOS Release 12.2(25)EZ. Catalyst 3750 switches and Cisco EtherSwitch service modules can be in the same switch stack. Within this switch stack, the Catalyst 3750 switch or the Cisco EtherSwitch service module can be the stack master.

Please click here for more information on manage Switch stacks.

For the code, the major version must match, but you can have minor revisions between the two. You must force the mater to push the IOS to other stack memeber it does not do it automatically. Please click here for 3750 stack software compatibility.

It is highly recommended that switches in the same stack run the same code with same feature set. If a switch becomes the new master, that switch should support same feature set as the master or else you will have inconsistency. Switches with different cisco ios softwarer versions likely have different stack protocol versions. Switches with different major version numbers are incompatable and cannot exist in the same stack.

What's the maximum number of LDAP Directories configurable in CCM 7?


What is the maximum number of LDAP directories configurable in CCM7? We have users spread across 25 OUs. Is there a server that could gather all of these accounts and serve them up to CCM under just one context?

You can configure up to 5 LDAP agreements. In your case, you'll need to set your search at the root and then use AD permissions to deny the LDAP user the ability to see objects it shouldn't see. Each agreement can point to a different search space or "OU" in LDAP.

The synchronization is performed by a process called Cisco DirSync, which is enabled through the Serviceability web page. When enabled, it allows one to five synchronization agreements to be configured in the system. An agreement specifies a search base that is a position in the LDAP tree where Unified CM will begin its search for user accounts to import. Unified CM can import only users that exist in the domain specified by the search base for a particular synchronization agreement.
So, you can only use type of import (i.e., AD, Sun, etc) - if you go AD, that's the only choice. You can then set up separate agreements which specify specific OU's in AD that you'd like to search for users.
Again, in the original case of having 25 OU's, then you could consider the following:
Reorganization of the AD tree. Break those 25 OU's into 5 logical groups or a single group (i.e., Users) where you'd set up an agreement for. If you don't maintain AD, this isn't likely to happen.
You can set your search base as the root of the AD tree. You would then need to use permissions within AD to limit the objects and containers that your LDAP Dir Sync user can actually access. Again, this could get a bit involved depending on what you're dealing with in AD and, if you don’t control AD, you'll have to do some convincing here to get this done. But this is an option and it works - have done it elsewhere.

Cisco 1841 + HWIC-2SHDSL poor upload throughput


Has anyone had any experience with a Cisco 1841 and a HWIC-2SHDSL? The problem we are having is very very poor upload speeds on a 1Mbps/1Mbps 4 wire G.SHDSL service maxing out at ~ 10-15KBps egress. The download speed is fine up to ~ 1Mbps ingress.
The service provider claims there is no issue with the circuit, and we are now forced to focus our attention on the router/ WIC card.
There does appear to be some OAM errors incrementing very slowly(~200 over 72 hours) on ATM PVC sub-interface, but there are no CRC errors on SHDSL controller. The SHDSL seems to be connected correctly with the right line coding/ rate as per the service provider recommended settings.

One resolution to the problem is to make sure you have set the vbr-nrt on the atm pvc

interface ATM0/1/0.33
Pvc 0/33
vbr-nrt 1024 1024

How can you redistribute any route into OSP?


We have 2 routers at home network. 2650xm ix connected to ISP Cable modem 2620 is connected to 2650XM by switch and they both are in same network.
Routing protocol config on 2650

router ospf 10
log-adjacency-changes
redistribute connected
network 192.168.1.0 0.0.0.255 area 0
!
router rip
version 2
network 192.168.1.0
default-information originate

Why does router 2620 learn route from 2650, using rip as default? As ospf has less AD which is 110 then rip? Right now 2650 is advertising routes to 2620 router by Rip and OSPF and 2620 has chosen Rip protocol as compare to OSPF. Can someone explain why this is so?

You can redistribute any route into OSPF with the exception of the default route.
To generate a default route into OSPF
  1. You need the default route in the router generating the advertising along with the command default information-originate
  2. You can use the command default information-originate always when the router does not have a default route on its routing table.
If you want the 2620 router to obtain the default via OSPF, we would recommend using option 1.

The 2620 has chosen the RIP default-route because only RIP is sending a default-route from the 2651. Using "redistribute connected" under the OSPF configuration will not tell OSPF to advertise a default route.
So if you want a default-route to be advertised by OSPF as well as RIP you need to use one of the options listed above.

If two routers are ospf neighbors then they will exchange the hello packets with respect to time-interval's configured on those interfaces.

If the 2620 needs to reach the internet, per your current configuration, it will use RIP to reach the router advertising the default route.
Once the packet reaches the ASBR router, it will use static to reach the internet (next hop 96.51.144.1).
The packet won't be dropped unless you have NAT issues.

How to run its-CISCO.2.0.1.0.tcl


We have CME and FXS and FXO. We placed call form analog phone connected to FXS to 8000 and we tried to run the its-CISCO.2.0.1.0.tcl on my 2801 router. We added the files to router flash memory and we added the following configuration:
application
service autoatt flash:its-CISCO.2.0.1.0.tcl
param operator 0
paramspace english language en
paramspace english index 0
paramspace english location flash:
paramspace english prefix en
param aa-pilot 8000
!
We am not sure about the how to make the dial-peers and the call flow.

You can use the following script
dial-peer voice xx pots
service foo
port x/x/x
Digital ports use "incoming called-number ." instead of "port".
same for voip DP, plus "codec g711u" and "no vad".

The first config activate service when going off-hook. Typically used for FXO.
Generally is not needed to activate services for local phones. When it is, ideally the service should support mode "out-bound".

Services are activated by incoming DP, except for services supporting out-bound mode (not your case). Also please note that you cannot change the audio file without a reload, because even if you overwrite file in flash, IOS caches the content and no there is no know working way to refresh it.

Service is configured with out-bound keyword, and script entry point is ev_handoff instead of ev_setup_indication. Generally, the scripts do support both.

Change in behavior of ssh session after IOS upgrade


We upgraded a series of 3560s and 4506s to version 12.2(53)SE and 12.2(53)SG1, respectively. Before the upgrade, we would login to the switches using an SSH client. We would enter a user id and password for the initial connection and then if we wanted to get into enable mode, we had to enter a separate password. Now, after the upgrade, on the 3560s, we are automatically placed into enable mode after entering the initial userid/password sequence. There's no need to enter a separate enable password. On the 4506s, the functionality is the same as before the upgrade. Any ideas on what happened and how we might be able to get the 3560s back to the original behavior?

Diagnostic Steps

1) It can be problem with aaa configuration in your switches for enable mode authentication. The below sample configuration which will go for enable level password authentication also with TACAS server configured for authetication.

aaa new-model
aaa authentication login default group tacacs+ line
aaa authentication enable default group tacacs+ enable

2) You can try to add 'aaa new-model' to the configuration
3) You can try to remove the 'password' command from the 'line vty' section.
