Configuring Trunk ports – Lab 1.3

Posted: February 26, 2006 by sankar in Crabs, Lab 1.3

Cat 6500

 set trunk #mod/port# dot1q on (Other options include off, negotiate etc)

 set vlan #vlanno# #mod/port# (This defines the native vlan on the trunk port)

Cat 3550

switchport trunk encapsulation dot1q (Always use this command first before configuring mode as trunk) 

switchport mode trunk

switchport trunk native vlan #vlanno#

switchport trunk allowed vlan #x,y,z#


int fa0/1

 switchport mode trunk

 no shut

 switchport trunk encap dot1q  (This command is not really needed, because nm-16esw supports only dot1q trunking)

 switchport trunk native vlan #vlanno#
