Routing VLAN 1 on S2500

It appears that routing VLAN 1 on the S2500 is disabled by default. I'm guessing VLAN 1 may be the default management VLAN so routing is disabled for security reasons.

 

Can someone verify and tell me how to change the management VLAN or other configuration so that I can route VLAN 1?

 

Thanks,

Re: Routing VLAN 1 on S2500

Are you getting an error message?

 

Are you trying to do static routing or OSPF?

Re: Routing VLAN 1 on S2500

I use static routes but these vlans are local to the switch so it creates the routes itself. I can't ping or access devices in other VLAN's. There's no error message, it simply behaves as there is no routing.

 

I can successfully PING and access devices within VLAN 1.

Re: Routing VLAN 1 on S2500

Also, other VLANs are routing as expected.

Can you post the output of show ip route and show interface-config vlan 1?

Mark,

Can you provide a copy of your configuration?

Re: Routing VLAN 1 on S2500

Mark,

Just an observation, your vlan 1 interface is a .10 while all your other vlans are .1. Just want to make sure your client DGs on VLAN 1 are correct.

 

Best regards,

Re: Routing VLAN 1 on S2500

This is just a test configuration. I can't remember why I selected .10 but my client IP's are in range. The vlan network is 10.99.0.0 /20 so my range is from 10.99.0.1 through 10.99.15.255.

 

I can put a client on VLAN 3 and can't PING the gateway to VLAN 1.

If I have a client in VLAN 1, I can PING the VLAN 1 gateway but can't ping other VLAN gateways.
