Configuring Trunk ports – 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#

NM-16ESW

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#

Lab 1.3 – Configuring vlans – Voice and Data (Cat 6500 and 3550)

set vtp domain #domainname#

set vtp mode {server|transparent|client}

config)#

vtp mode #server|transparent|client#

vtp domain #domainname#

vlan #vlanno#

    name #name#  (Sub-mode, define 2 vlans for voice and data)

int fa0/1

 switchport mode access (IOS defaults to Dynamic mode in some versions, so this command is necessary)

 switchport access vlan #datavlan#

 switchport voice vlan #voicevlan#

 spanning-tree portfast

NM-16ESW

Syntax is similar to 3550.

Log into the 3800/3700 router and configure vlans just like in a 3550 switch

Define vlans in vlan database mode.
