Re: [essex vlan]cannot ping vm on other compute node

 

thank you, Kevin S, and also thanks George

i did this command in the beginning of the time when i meet this
problem, and it failed because """sw-31(config)#vlan 105
VTP VLAN configuration not allowed when device is in CLIENT mode."""
meanwhile i'm guided to a wrong way by our network administrator,
since i'm very new to switcher config.

yes, by add a vlan id to switch, the problem is solved. and switcher
must be putted to vtp server mode. the client mode just copy vlan
config from a server, so any configure about vlan is ignored.

ps: i followed this qa on cisco site:

thank you very much for your help
