should a CSM virtual respond to a ping?

[bofawcett]

Does a virtual address on a CSM normally respond to a ping?

If this is not default behavior, how would you configure to respond?

Thanks

if router mode is used...and

if a real server on the server side is up and reachable, then yes.

if a real server is not up/reachable, then it should be no.

I think the code was changed for it to work this way..which makes sense.

If memory serves me right, in older code, it would respond, even if no real server was available/reachable.

hope this helps.

This not the behavior I am seeing. Both reals are up and pingable. I get no response from the virtual. This is from either the network or logged into the 6513 that the CSM is in. System is in router mode.

issue these commands from the 6500

(The number 2 is the slot the module is installed in, adjust if necessary.)

show module csm 2 real

show mod csm 2 vserver

show mod csm 2 serverfarm

ping mod csm 2 real

ping mod csm 2 gateway

ping mod csm 2 (your vip ip address)

The results could help indicate where the problem is.

If you wish, post the results here and we'll go from there.

Verify you have an "alias" command on the server side, it acts as a gateway.

vlan 313 server

ip address 10.x.x.3 255.255.255.0

alias x.x.x.1 255.255.255.0

this whole thing could be a routing issue

Make sure the client side "gateway" statement only exists for 1 client side vlan.

I repeat, only 1 client side vlan statement can have a gateway statement. This is KEY!!!

vlan 192 client

ip address x.x.x.x 255.255.255.0

gateway x.x.x..1 255.255.255.0

vlan 193 client

ip address x.x.x.x 255.255.255.0

make sure there is no gateway statement for this second client side vlan
