lportQ922State
Module: CASCADE-MIB
OID (symbolic): CASCADE-MIB::lportQ922State
OID (numeric): 1.3.6.1.4.1.277.1.5.1.1.166
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-only
Description: Q.922 state. This object only makes sense when Q.922 is enabled.
What is lportQ922State?
This read-only field reports the current state of the Q.922/LAPD data-link state machine on this port, progressing through states like tei-unassigned, assign-awaiting, tei-assigned, and multiple-frame-established, and per its description is only meaningful when lportQ922Enable is actually turned on. An admin watching this during SVC troubleshooting can tell exactly where the Q.922 link-establishment handshake is stuck if it never reaches multiple-frame-established, the state indicating the LAPD link is fully up and able to carry call-control signaling. For example, a port stuck reporting tei-assigned(4) instead of progressing to multiple-frame-established(7) indicates the TEI negotiation succeeded but the actual multi-frame LAPD link establishment is failing, a much narrower troubleshooting target than a generic SVC-not-working complaint.
