unable to ping local interface vlan on C3 securestack

[Wim_Simons]

Hi,
I created a interface vlan on a C3 securestack with the following :

interface vlan 104
ip address 10.107.15.1 255.255.255.0
no shutdown

show interface vlan 104 gives :

Vlan 104 is Administratively UP
Vlan 104 is Operationally DOWN
Internet Address is 10.107.15.1 , Subnet Mask is 255.255.255.0
Mac Address is: 001F.4530.4517
The name of this device is Vlan 104
The MTU is 1500 bytes
The bandwidth is 0 Mb/s
Encapsulation type Ethernet
ARP Timeout: 14400 seconds

ping 10.107.15.1
no answer from 10.107.15.1

in the result of the command "show ip route" the ip range 10.107.15.1 does not show up.

other interface vlans on the same stack do work and show up in the ip route as local.

I compared the config with another C3 where everything works and don't see any difference.

Can anyone help me ?

thanks,

Wim

The reason is because the interface created for "Vlan 104 is Operationally DOWN."
Fix: Set a port to a vlan or egress that VLAN on an uplink port (as suggested) and make sure the assigned port has physical link. It should work.

ok thanks, I will try this first thing on monday.

You need to have the interface up. This will be accomplished by port assignment to that vlan. At least egress. The port must be up.

Assign a Port to the vlan and connect it to make it operationally up.
