HP 4104 VLAN question

DPower — Tue, 18 Mar 2008 18:01:16 GMT

Running an HP 4104GL with HP G.07.104

I'm trying to configure a VLAN on this switch and not having much luck. I've successfully created the VLAN and added 1 (C20) port. The switch IP is 10.1.1.250/24. The VLAN IP is 10.1.3.254/24. I cannot ping the VLAN IP, but I can ping the switch. If I plug a device into C20 I can ping the VLAN, but not the switch. I've enable IP routing as well. If I issue "show ip route" I do not see the 10.1.3.x network listed. It will not take a static route either. Any ideas how I can get the switch to recognize that it is supporting 2 networks?

Make sure that port C20 is up (has a link), otherwise the VLAN will still be considered as down.

Progress! I did attach a small 5 port switch to C20 and VLAN 300 did show up when I issued a "Show IP Route". However I am unable to ping through the switch. If I plug my laptop on the 10.1.3.x network I can ping only 10.1.3.x devices. I cannot ping the switch 10.1.1.248. I do have IP Routing enabled. If I telnet to the switch I can ping both networks. I'd think if IP ROUTING is enabled it would route! It's all very frustrating.

Here's a copy of my config...

Ahhh... I see the problem. You have the management-vlan feature enabled. This prevents routing on that VLAN.

Solution:
4104(config)# no management-vlan 1
