Netvanta 3200 | (Interface) Frame Relay, Sub-Relay & Loopback Questions
Good day...
I am replacing an Samsung IBG-1000 for a customer using an Adtran Netvanta 3200. I have contacted the clients provider (MegaPath | T1) and asked for general support however they do not support the Adtran unfortunately and have referred me to try Adtran.
When the Adtran is connected to the client T1 and when viewing the "System Summary" => "WAN Summary" indicates that the "WAN Interface" is UP.
Likewise when viewing the "WAN Interface Encapsulation" status is indicated as ACTIVE.
Firmware Version: R11.4.4
The Questions
1) When viewing the "System Summary" the WARNING: Warning a potential problem has been detected with your system. Please go this troubleshooting page for more detail.
Layer 2 Protocols Error: Error fr1 is administratively up, but the sub interface, fr 1.500 (VC500), is inactive. Make sure fr1 is up. If the problem persists contact your service provider.
EDIT:
This unit is currently disconnected from the circuit, but here is the return from "show interface".

What is this error indicating and how would I resolve the situation of "activating" fr 1.500?
2) Is a "loopback" interface required to be added manually or is this created once the device detects an active link?
I appreciate your help and input greatly
