[c-nsp] PAgP or LACP timers

[Ran Liebermann]

Hi all,

I have a scenario in which there are two 3750 switches for the IBM blade
center.
I'd like to implement etherchannel between the switches so that 8 GE ports
will pass through 8 of the blade servers, while each blade is acting as a
bridge. So far so good.
Each of the blades is running an application, that when fails it also
disrupts the bridging capabilities of the server, therefore not allowing
frames from one side to the other.

Now, the thing is that whenever a blade server is inserted in the chassis
the ports on the switches become up, so in order to control whether a port
is a member of a channel-group I must deploy PAgP or LACP.
However, the inherent timers of the protocols are somewhat slow, 30 seconds
between keepalives, which is too long in order to detect a failure.

My question is divided to two:
1. Is it possible to somehow change the timers of PAgP or LACP? (we found an
"lacp rate fast" command only on 6500).
2. Do you have a different suggestion for the above requirements?

Many thanks,
