We have installed a HWIC-4esw on a remote C2800 router.
Currently the router has a configuration to allow 1 pc and 1 phone on the native C2800 L2 ports. We would like to add an additional phone and PC in that location, and the easiest way "seems" to be to configure it similar to the document at
adding the devices in separate vlans on the L3 ports.
The 2800 is connected to our campus via a PTP T1 on serial 0/1
The configuration seems pretty straightforward, but I am having difficulties with it.
Should I be able to ping a VLAN interface created on this router?
int vlan 151
ip address 10.51.x.x 255.255.255.0
int range fa0/3/0-3
switch access vlan 151
I can't ping the int, and there is no route in the table such as
10.51.x.x connected via VLAN151
The vlan is listed under Show vlan-switch, and ports assigned to it show up correctly, but no devices that connect to it can go anywhere.
IOS version 12.4.22T
As you noted, the only way to bring up a SVI (Switch Virtual Interface) is to have a switchport that is member of that Vlan in up/up status.
You can also bring up that SVI if you had a trunk switchport and allowing that Vlan in the trunk, not the case here but I thought you should know.
Now, the inability to ping anything beyond the gateway could be due to the lack of subnet advertising via a dynamic routing protocol.
While the router has a static default route towards 10.81.1.xx, does that network knows how to get back to 10.51.x.x?
The problem seems to be at the remote end.
