Etherchannel limitations WS-X4548-GB-RJ45

Is anyone aware of any limitation on building an etherchannel on the abovementioned linecard, when bundling more than one port on the same card? The 4506 is using a 6L-E supervisor engine 12.2(54)SG1.

If it's done on a 6500 with a WS-X6148-GE-TX linecard it affectivley can only reach 1gb throughput.
There are no limitation information on this WS-X4548-GB-RJ45 (just like we could find for WS-X6148-GE-TX)...

Please pay attention to the distribution of the Etherchannel ports across the different ASIC ports group in the card (as per the 8-to-1 oversubscription) of this classic module WS-X4548-GB-RJ45 ==> Capacity of 6 Gbps (full duplex) connections to the central forwarding engine

• Bandwidth is allocated across six 8-port groups, providing 1 Gbps per port group

The amount of oversubscription can be controlled by varying the number of ports used at 1000 Mbps. All ports can use Gigabit EtherChannel or IEEE 802.3ad for high-speed interconnection applications
