I am trying to configure EtherChannel (802.3ad Link Aggregation) between a Dell PowerConnect 5324 and Cisco 3600 series router. I cannot ping between the two devices.

 

The Cisco 3600 router with IOS 12.4 supports EtherChannel (LAG), however it does not support channel group "mode" commands (LACP). 

 

A 3600 router interface can only have "channel-group ".  It does not support command tags such as "auto", "on" or "desirable".

 

I did not configure 802.1q (VLAN trunking) to prove that this is not causing the issue. 

 

Can someone please advise me on the proper way to configure this so I can ping between the two devices?  I'm assuming this issue applies to Cisco 2600 and Cisco 3700 series routers as well.  I also tested this using a PowerConnect 5224 and found the same problem.

Here is how my devices are configured:

---------------------------------------------

interface Port-channel1
 ip address 10.0.18.101 255.255.255.0

Thanks in advance for your help.
