Hello,
We currently have an issue with an Aruba 2930F.
We have 7 Vlans on this switch and have an issue with one of the Vlans.
When the vlan is tagged on the port that has the uplink to the rest of the network, the vlan stops working on the switch.
When the port with the uplink issnt tagged or has the vlan disabled on the port, then the vlan works whithout issues.
We want to use Vlan55 for our new telephone system. the device is connected to port 12 which is untagged in vlan55, this also provides DHCP for this vlan.
It all works when i connect the phone on a tagged port 55 (the phone is configured to use vlan 55). the phone receives an IP address and is able to make a call.
When i tag port 28 which is the port that connects to our main server room, the vlan stops working.
The phone connected to the switch is unable to connect to its provider.
When the port is set to forbidden vlan 55 it all works again.
Config of the switch below.
