But I am unable to assign the virtual NLB MAC address used by the cluster to multiple switch ports. I can however do it on a Cisco 2950. Is there anyway to make this work with the 4507R? Both of my servers are connected to it, and I would rather not have to stick another switch in the middle. I'm running the Supervisor Engine II-Plus.
My goal is to eliminate all of the flooding that the current unicast NLB mode is doing.
No problem. :) At least now you know the switch can do it.
If you can find a way to get MS to assign a true multicast MAC, that would be best.
Otherwise, I believe you can still do it by running the same command twice, once for each interface.
EDIT: Interestingly enough, I found this:
Note: Ensure that you use the multicast mode on the NLB cluster. Cisco recommends that you do not use multicast MAC addresses that begin with 01 because they are known to have a conflict with the IGMP setup.
We have 3 identical switches configured by someone else and would like to claim some of the Gigabit ports(G1/G2/G3/G4) for use on servers. When we try to change the wiring and configuration, we run in to connectivity issues. Attached is a des...
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
