Configuring VLAN's on two HP procurve switches

Question

(Newbie to VLANs)

Trying to route a new ISP(Microwave link) from one of my out building to my computer room and hence my firewall. Old ISP came direct into firewall. In the outbuilding the Microwave modem connects with cat5 to HP Procurve 2524 switch. Because this ISP is coming through my internal network, I plan on using a new vlan called "airspeed" only for this ISP traffic. Up until now I've just been using the "Default_vlan" on both HP switches (4108 + 2524).

So far I've been unable to ping from my laptop to the ISP modem both of which are on the new vlan 2 ("Airspeed"). No traffic needs to cross from vlan 2 to vlan 1 so I've left the ports as untagged. I've used the subnet provide from my ISP as the new vlan 2 subnet. Can anybody see what I'm doing wrong here? I've added the configuration of both switch below.

Thanks in advance,

Answer 1

According to the configuration you posted, you only have one port (24) of the switch configured for vlan2. If your laptop and the modem are on different ports (which I presume they are) then both ports need to be untagged members of vlan 2 for this to work.

For example, if the other device is on port 25 you should have:

vlan 1
name "DEFAULT_VLAN"
untagged 1-23,26
no untagged 24-25
ip address 128.1.146.204 255.255.0.0
exit
vlan 2
name "Airspeed"
untagged 24-25
ip address 77.75.00.51 255.255.255.248
exit
no aaa port-access authenticator active

instead of what you posted.
