How to configure VLAN trunk between HP and Cisco switch?

VLAN trunk between HP and Cisco switch

Many enterprises use multi-vendor switching environment and it takes quite an effort for network administrators to configure and manage different vendor devices. In fact incompatibility of protocols also become quite a headache.

Considering the above, this article gives assistance in configuring trunk between HP Switch and Cisco Switch.

Example Scenario

A sample scenario has been created as per below diagram –

As shown above, Cisco Switch is working as Layer 3 Gateway for 2 VLANs (Admin and HR VLAN).HP switches are working as Layer 2 edge switches.

Table below will be referred to while configuring VLAN Trunk to  the devices –

On Cisco Switch (CORE)

Create VLAN 10 and 20 and SVI for both.

Cisco-CORE(config)#vlan 10Cisco-CORE (config-vlan)#name “ADMIN”

Cisco-CORE (config-vlan)#exit

Cisco-CORE (config)#interface vlan 10

Cisco-CORE (config-vlan)#ip address 192.168.10.1 255.255.255.0

Cisco-CORE (config-vlan)#no shut
 
Cisco-CORE (config-vlan)#vlan 20

Cisco-CORE (config-vlan)#name “HR”

Cisco-CORE (config-vlan)#exit

Cisco-CORE (config)#interface vlan 20

Cisco-CORE (config-vlan)#ip address 192.168.20.1 255.255.255.0

Cisco-CORE (config-vlan)#no shut

Configure Trunk and Allow selective VLANs on Each Trunk

1. VLAN 10 allowed on TRUNK between CORE and SW1
2. VLAN 20 allowed on TRUNK between CORE and SW2

Cisco-CORE (config)#interface GigabitEthernet 0/1Cisco-CORE (config-if)#description “CORE-HP-SW1”

Cisco-CORE (config-if)#switchport trunk encapsulation dot1q

Cisco-CORE (config-if)#switchport trunk allowed vlan 10

Cisco-CORE (config-if)#switchport mode trunk

Cisco-CORE (config-if)#no shut

Cisco-CORE (config)#interface GigabitEthernet 0/2

Cisco-CORE (config-if)#description “CORE-HP-SW2”

Cisco-CORE (config-if)#switchport trunk encapsulation dot1q

Cisco-CORE (config-if)#switchport trunk allowed vlan 20

Cisco-CORE (config-if)#switchport mode trunk

Cisco-CORE (config-if)#no shut

On HP Switch (SW1)

HP-SW1(config)#vlan 10HP-SW1 (config)#name “ADMIN”

HP-SW1 (config)#untagged 2-47

HP-SW1 (config)#tagged 1 

On HP Switch (SW2)

HP-SW2(config)#vlan 20HP-SW2(config)#name “HR”

HP-SW2(config)#untagged 2-47

HP-SW2(config)#tagged 1
