How to connect a HP A5120 switch to a Cisco Small Business Switch 302-8 ( SRW208-8p)
First the part of the cisco switch. In my configuration I had more than 1 vlan’s. I wanted that only vlan 1 to 3 are forwarded to the other switch. To do this you need to configure the following on the Cisco Switch:
Create a vlan database:
vlan database vlan 2-3,10-11 interface vlan 1 ip address xxx.xxx.xx1.252 255.255.255.0 no ip address dhcp
Standard the switches are auto negotiated on Access or Trunk. But in case you need you need to add the command: switchport mode trunk.
interface gigabitethernet2 switchport mode trunk switchport trunk allowed vlan add 2-3
HP A5120 Switch:
login to the switch. Go into the system-view mode. Add some vlan’s
vlan 1 igmp-snooping enable # vlan 2 name Wi-Fi # vlan 3 name Management interface Vlan-interface1 ip address xxx.xxx.xx1.253 255.255.255.0 # interface Vlan-interface2 ip address xxx.xxx.xx2.253 255.255.255.0 dhcp relay server-select 0 # interface Vlan-interface3 ip address xxx.xxx.xx3.253 255.255.255.0 dhcp select relay dhcp relay server-select 0
Configure the connected port to the Cisco Switch with a trunk. This is just a static trunk port. In a previous post I posted a trunk between 2 HP switches that one was with LACP.
interface GigabitEthernet1/0/7 port link-type trunk port trunk permit vlan 1 to 3
When you have configured this you can test this to configure on the cisco switch a separate port on a different VLAN for example VLAN 2 with an address and ping the switch ip address of that VLAN on the other switch.
