dear all,
when i tried to configure the port channel for link agregation for the uplink to a router. using the gigabit fibre interfaces available on SupervisiorIV 1000BaseX GBIC in slot 1 & 2 of the chassis 4507 but it did not work out?
but when i changed the interface to those avalilable in other module it worked out with the same configuration on the other interfaces i want ot know why it did not work on interface avaliable on SUPIV WS-X4515
regards

I think the valid possible combinations for a successful formation of etherchannel are:
desirable + auto
on + on
AFAIK a port in on mode can form a channel only with a port in on mode, because ports in on mode do not exchange PAgP packets.
Could you try changing the echannel option from on to auto and leaving the other one on desirable?

Hi Haris,
Which ports were you trying to use on the supervisors? Keep in mind, that with redundant supervisor IVs, only 1/1 and 2/1 are available.

Hello,
What were the configurations you used for both sides of the channel. Remember that if you're using a configuration that uses PAgP (desirable, auto) can not form a bundle if it's neighbor doesn't use PAgP (on or off).
Hope this helps.
Regards,
