I have upgraded varies switches and routers in the past. I have been tasked to upgrade the IOS on two 4500X switches I configured and IP address on the management port as well as my laptop, but can not ping the laptop or the 4500X. The only way I can ping the 4500X is from itself using the following command ping vrf mgmtVrf 10.40.255.2 if I try to ping using just ping 10.40.255.2 it doesn't work. Is there a detailed procedure anywhere on how to upgrade the IOS or is there something I need to add to the config in order to ping both ways?
