CSM trunks oversaturated?

Answered Question
Jan 31st, 2007

We have a CSM 4.1.6 in Hybridmode we noticed on the switch that the top talkers were maxing out 100% on one of the 4 trunks to the CSM it randomly changes ports steadily @ 100%. So my question is why doesnt the CSM use all trunks equally?

I have this problem too.

I'm using native mode but in Your case maybe this will help:

set port channel all distribution {ip | mac | session} [source | destination | both]

try to choose different balancing method aproptiate for Your traffic:

port-channel load-balance ?

dst-ip Dst IP Addr

dst-mac Dst Mac Addr

dst-port Dst TCP/UDP Port

mpls Load Balancing for MPLS packets

src-dst-ip Src XOR Dst IP Addr

src-dst-mac Src XOR Dst Mac Addr

src-dst-port Src XOR Dst TCP/UDP Port

src-ip Src IP Addr

src-mac Src Mac Addr

src-port Src TCP/UDP Port

Thanks for the quick response Marcin but it doesn't seem to like the command on CATOS both SUP & MSFC. Is there another way to apply it?
