Hello all,
We've been running 2 6500, supervisor 1a/pfc/msfc for some years and as the network have grown, we bought 4 supervisor II, pfc2, msfc2 (no budget for Sup720 for now). I'm looking for hear from people who made this conversion for any tips they have.
The first difference we've found is the limitation in the number of HSRP groups (256 in Supervisor 1 and 16 in supervisor 2, sigh!).
If there are some thoughts, reports, regrets :-), etc, I will be glad to hear from you.
Thank you. Antonio
Hmmm. 16 system wide unique HSRP groups hardly seems like a limitation to me.
It does prevent you from doing
int x ip 10.1.x.1 /24 stand x whatever
repeat for x = 1 to 255.
However this is a convention that does not produce any network functional benefit.
There is nothing to prevent you from using the same standby group(s) on every interface. I have seen cases where two groups were used on each interface for load balancing but never more.
int x ip 10.1.x.1 /24 stand 1 ...... stand 2 .....
repeat for x - 1 to 255
Anyway for a full explanation see:-
you dont mention whether you are running CatOS /IOS or an integrated image....
16 group addresses or possibly some other limit (i think - a long time ago) - but you can reuse them within different subnets....MSFC / PFC IP doesnt use route caching, so better performance than a Sup 1A for some forwarding, and some better hardware assist.
sup1a EOL - note near the end on trade ins....
