I don't really need an L7 policy for this particular group, so wasn't going to add it in. I can add a dummy one in if necessary. This is the reason I cannot ping it?

yes you need it.

This is how you assign the serverfarm to the vip.

switch/User1(config)# policy-map multi-match SLB1

switch/User1(config-pmap)# class VIP-250-81

switch/User1(config-pmap-c)# no loadbalance policy SF_Linux4

switch/User1(config-pmap-c)#

gdufour-cat6k1#ping 192.168.100.250

Type escape sequence to abort.

Sending 5, 100-byte ICMP Echos to 192.168.100.250, timeout is 2 seconds:

Success rate is 0 percent (0/5)

Type escape sequence to abort.

It's working thanks, just applied it as you were answering. I just put the default class into it.

Yay! Now it's testing time :)
