port channel- router 3725

[catalystexpress]

Hi All,

Am using GNS3 software and have setup 2 cisco 3725 as below

R1 ---- portchannel 1------R2

the port channel is up but am not able to ping the link

am not sure if this is possible, because am not able to set the lacp protocol nor set the channel-group mode to enable

thank you very much for all the help....

Hi,

There is a restriction on configuring LACP/PAGP as they are not supported. Here is a good doc, thought of sharing with you.

Hi,

switching in GNS3 is done with a router equipped with an ethernet network module NM-16ESW but you are limited in what you can do, just a few unsupported features:

-port-security

-RSTP and MSTP and PVST(+)

-PagP and LACP

-DTP

...

Regards.

Alain.

I could successfully experiment port-channel with a couple of c7200 direct connected at GNS3 .
