I have a catalyst 6509, installed with 2 sup2(also wtih msfc2) and some interface modules. The two msfc2 work in SRM redundancy mode.There are some servers and hosts connect directly to the 6509. The problem is when I chang the ip address of a server, the hosts in the same vlan with that server can ping the server, but the hosts in other vlans can't ping the server. If I restore the server with the previous ip address, then all the hosts can ping the server. Why? Is it a bug of the SRM features?
