We have a variety of 5448 switches in our network right now, all ports are configured as such (simplified of course, but this is the gist of it):
| 1 | interface range ethernet g(1-48) |
| 2 | switchport trunk native vlan 2 |
| 3 | exit |
| 4 | switchport trunk allowed vlan add 12 |
| 5 | exit |
Our SIP phones plug into the switch, computers plug into the phones. The phones grab a DHCP response which tells them to switch the VOIP traffic to vlan 12 tagged (where they request a dhcp address from a server on that network), the computer sends untagged traffic via vlan 2 on the office network.
I'm trying to configure our 6248 switch to do the same thing, but some of the command structure has changed. Tagged ports can no long have an untagged native vlan on them, so I'm not sure how to achieve the same setup. When I set the ports to general mode, set the pvid to 2 and add port 12, I'm unable to get a dhcp address or do anything even bypassing the phone and plugging directly into the switch with a laptop.
Setting the port to access mode and dropping it into vlan 2 works fine for office traffic via my test laptop, but setting the voice vlan to 12 isn't allowing any tagged traffic to move over vlan 12 (dhcp request is never seen at the dhcp server from the phone).
Any help would be appreciated.
