HP Switch: virtual serial configuration VLAN Trunk

Abstract: Ethernet Serial port settings, HP MSR900 often encounter lots of trouble, whether it is to forget the set command, or forget operation process, is a very annoying thing, this article mainly describes the set of questions about virtual serial port Ethernet switch.

Switch serial port (Trunk) function:

In the Ethernet switch relay through serial port using the following two package types:

-          IEEE 802.1Q

ISL (Inter Switch Link, Cisco private)

The configuration steps

The first step: add VLAN on the switch.

Switch1#vlan database

Switch1 (VLAN) #vlan 2

Switch1 (VLAN) #vlan 3

Switch1 (VLAN) #exit

The second step: add the interface to the corresponding VLAN

Switch1#config terminal

Switch1 (config) #interface fastEthernet 0/1

Switch1 (config-if-range) #switchport access VLAN 2

Switch1 (config) #interface fastEthernet 0/2

Switch1 (config-if-range) #switchport access VLAN 3

The third step: Internet configuration switches between port serial port (Trunk)

Switch1 (config) #interface f0/15

Switch1 (config-if-range) #switchport mode trunk

Other related commands

Removal of VLAN:

Switch (config-if) #switchport trunk allowed VLAN removevlan-list

Add VLAN:

Switch (config-if) #switchport trunk allowed VLAN add vlan-list

View port state:

Switch#show interface f0/15switchport

List check relay port allows VLAN:

Switch#show interface interface-id switchport
