I have a Cisco 2940, which is connected via a trunk to a 3750, which in turn connects to the core switch.
I have a need to change the management address and vlan on the switch, from the default '1' to 999.
As is normal the switch is uplinked via a trunk interface, the trunk has a native vlan 999 and can be managed remotely fine when configured with an IP address in vlan 1.
However when I change the default-gateway to the gateway address of vlan 999, configure a vlan 999 address, and do a no shut, I can not ping out at all. VTP is distributing vlan 999 fine, it is not blocked in the trunk and I know the default-gateway address is good - I can ping it from my PC - any ideas?
interface GigabitEthernet0/1 switchport trunk native vlan 999 switchport mode trunkI've been trying to configure the trunk for dot1q, however have the following:SGH09-NetworkServi(config-if)#switchport trunk ? allowed Set allowed VLAN characteristics when interface is in trunking mode native Set trunking native characteristics when interface is in trunking mode pruning Set pruning VLAN characteristics when interface is in trunking modedot1q is not selectable.However with the above configurations, and vlan 1 IP address configured I can remotely manage the switch fine. If I then change the management address to vlan 999, and set the relevant defaul gateway - I can not ping in or out.Hope someone can help!
