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: https://learningnetwork.cisco.com/thread/15990 thank you very much for your help _______________________________________________ Mailing list: https://launchpad.net/~openstack Post to : openstack@lists.launchpad.net Unsubscribe : https://launchpad.net/~openstack More help : https://help.launchpad.net/ListHelp
