Cisco 2911 Router - HP2920 Switches - VLANS

Hello,

I'm working with a Cisco 2911 Router and 4 2900 series HP switches. I would like to create a VLAN on the last switch in the daisy chain. I set all this up in Cisco Packet Tracer and it was very straight forward when using the Cisco L2 switches but with the HP switches I'm struggling. As far as the router configuration I think it's called "router on a stick" and I've uploaded that configuration. On the Cisco switches it was very easy to configure, any port connect to the router or another switch was just trunked to pass on the encapsulation then add the VLAN # to the switch and ports you wanted on that VLAN. On the HP switches its "different". I'm fairly new to this so............

Basically what I have is:

Router port 0/1 connected to switch1 port 23

Switch1 port 24 connected to switch2 port 23

Switch2 port 24 connected to switch3 port 23

Switch3 port 24 connected to switch4 port 23

Switch4 is where I would like to create the VLAN

 

One question is, where can I download the HP Network Simulator and two, how do I configure the switches in this layout?

 

Thanks,

 

Jeff

On all HP switches, you have to add VLANs manually , and assign ports 23 and 24 tagged.

On out of the box cisco switches, some things happen automagically:  Learning VLANs from neighbour switch, setting ports to trunk mode.  But it's best practice to disable all that auto stuff and do it manual.

btw: your cisco config isn't 2911 router, but 1941

Thanks 16again,

So starting from the router (and it is a 1941)

Configure VLAN 10 and DHCP for VLAN 10

ip dhcp pool 10
 network 10.0.10.0 255.255.255.0
 default-router 10.0.10.1
interface GigabitEthernet0/1.10
 encapsulation dot1Q 10
 ip address 10.0.10.1 255.255.255.0

Next I would tag all 23 and 24 ports on the switches. This would allow encapsulated VLAN 10 packets to be transferred from switch to switch.

 

So far so good? I could configure this right now without affecting the current network?

Next would come creating VLAN 10 on the switch. VLAN 10 will be on switch4, the last in the chain. I only need to add VLAN 10 to that last switch?

 

Thanks,

You need to add VLAN 10 to all switches first.  Adding tagged member ports (23-24) is done under its VLAN.
