Cannot ping in/out of switch but can ping through it

[BradK1]

I recently setup a new extreme switch that I am having a problem with. The switch itself is not able to ping out and other devices aren't able to ping it. .Though I am able to ping through the switch. For example:

laptop>problem switch> netgear switch>dhcp server works.

All configuration settings are factory default except DHCP client has been enable.

Does anyone know what could be causing this issue? It persists through power cycling. The workaround is to enable ipforwarding, which is unusual as I haven't had to do that with other switches.

Okay. Thanks for your help Eric.

Not 100% sure, but I think that DHCP might be getting assigned to the management VLAN (which is connected to the management virtual router), not the default vlan. Therefore it's not local to the LAN segment and requires that routing be enabled to respond. This is a hunch, as we always statically assign the IP's to the vlan we're managing from (not usually the built-in management vlan). Hopefully someone more knowledgeable on this config will comment.

[BradK1]

My IP address is assigned by the DHCP server.
Error: DHCP/BOOTP is enabled on the VLAN

Does anyone know why enabling IP forwarding resolves the issue? As well why am I able to ping through the switch, but the switch isn't able to ping other devices and vice versa?

Thanks Brad. I think you need to simply add the IP to your default vlan. "config vlan default ipaddress x.x.x.x y.y.y.y"

Brian all devices are on same subnet and I unplugged the switch with 192.168.101.132 IP address and pinged that IP again and wasn't able to find another device.
