I am attempting to get LACP working with a Cisco 2960 and an IBM I7 server.
The connection seems redundant. I can unplug GI0/8 and traffic still flows and clients are not disconnected from the IBM I7. I can do the same with GI0/9 once GI0/8 is plugged back in.
Two issues.
1. How can I change the LACP timer from slow to fast?
2. Why does my port Gi0/8 show as INDEP in the show lacp detail command?
Port: Gi0/8
------------
Port state = Up Sngl-port-Bndl Mstr Not-in-Bndl
Channel group = 3 Mode = Active Gcchange = -
Port-channel = null GC = - Pseudo port-channel = Po3
Port index = 0 Load = 0x00 Protocol = LACP
Flags: S - Device is sending Slow LACPDUs F - Device is sending fast LACPDUs.
A - Device is in active mode. P - Device is in passive mode.
Local information:

indep means the port is not part of the bundle
Can you post the output of "show port-channel summary"?

Hi,
With IBMi7 the support for LACP starts to my knowledge since i7.1 TR7. If that is your case will you please post the DSPLIND (with AGGRSCL option) command output.
As for the LACP fast timer setting while it can be configured on various Cisco boxes I am affraid it cannot be done with Cat2960.
Thanks & Regards,
Antonin
