RE: How to configure redundancy on access port?

I can't speak to his particular situation, however I have 3750's stacked and I'm rocking that configuration for redundancy and throughput.

In his particular situation, if all you're after is redundancy, configure the nic for redundant mode (not bonded) and it doesn't matter if they're two different chassis. Like I said, both NICs will be enabled, only one will be active. One switch dies, the other becomes active.

I thought newer code/access switches enabled bonding across different chassis (not stacked) but not sure which model/IOS is required. Open a TAC case and ask. I just remember the 65XX had the VSS like stacking ability (w/out VSS) so I'm assuming it's only a matter of time till that feature floats down to the lower end gear.

Hope this helps,
JB

I thought the pc's were connected to different access
switches....port-channel to multiple nic's in pc would imply multichassis
etherchannel in access layer...i believe a feature recently introduced in
asr's/7609's, not sure about smaller access type switches doing
multi-chassis lag/etherchannel

Did I misunderstand you jb?

Thanks

Can't you use the Dell/HP/Intel drivers to be in redundancy mode? Basically
both NICs are running with one IP Address, where one is "sleeping" the other
isn't. Otherwise setup a port channel, but not sure your options on the
2960 line.

Like was mentioned earlier, your client is going to dictate your choice,
followed by your infrastructure.

Hope this helps!

I've configured windows OS as rip listener before. (i recall in some older
versions it was setting a registry key, but I think in newer versions it's a
windows option/component installable from add/remove programs) You can run
rip on the subnets/vlans to the pc's from the 6500's. Perhaps only inject
route you wish the pc's to learn, or perhaps only def rt. It seems that
anything else I think of with simple dual def gateways might not work nice
with carrier detect being up on interface to access switch, test it, also
test dual def gw's with different metric, maybe arp cache timeouts need to
be considered too...just brainstorming

Fhrp's (glbp,hsrp,vrrp,etc) might be good as someone previously mentioned,
rstp in network, root bridges pri/sec on 6500's
