I have two routers and have HSRP running between the fast ethernet interfaces. Actually there are two groups running. RTR_A real IP is .1 and it is Active for .3 (group 1). RTR_B real IP is .2 and it is Active for the .4 address (group 2). I want to remove one of the groups. Anyone know how I can see if the .4 virtual is being used as a default gateway by a client?
We're getting closer. I enabled accounting, sent some traffic, but the command show interface VLAN1 mac-acc shows the source MACs destined for the VLAN1 interface. That's works, but I may have clients pointing directly to the physical interface. Thanks for the command.
How can you determine that? A Client would have this information statically or dynamically within its TCP/IP information so what's to say this client hasn't be used for 2 weeks because the user was on vacation?
I'm afraid this request is not possible to accomplish without some leg work or having some technical support calls.
The command can be used to get a fair idea of the number of MACs sending traffic to router's interface. If we have just 2 routers and hosts, and if group 2 is active on Router B and no client is using .4, you shouldn't see any traffic right ?
It may or may not help depending on what else is going on in the LAN.
