Set of commands for troubleshooting on Cat 6500 with Sup 720:
I just deployed a nexus 7010 switch at a server farm. after deployment, it was notices that there are surges in latency across the network. The default gateway was then moved to the nexus, with this pinging from an host on the same subnet there is intermitent burst is latency
Ping of about 80ms and sometimes even times out.
To me, this is strange.
NX-OS Version is 5-02a
This might require analysis of certain things, like configuration, connectivity between Nexus and Server, Module etc. I suggest you please open a discussion on this in LAN, Routing and Switching section and post configuration, module information etc there.
Another very helpful command is:
show cli list - This will display all available cli options at your current level
