Catalyst 2950 Switch

Cat2950#

Cat2950#conf t

Enter configuration commands, one per line. End with CNTL/Z.

!-- The VLAN Trunk Protocol (VTP) mode is set to server,

!-- and the VTP domain name to isset to cisco.

Cat2950(config)#vtp mode server

Setting device to VTP SERVER mode

Cat2950(config)#vtp domain cisco

Changing VTP domain name from VitalCom to cisco

!-- Created two VLANs: VLAN10 and VLAN20.
