ceSctpStatT1expired
Module: CISCO-SCTP-MIB
OID (symbolic): CISCO-SCTP-MIB::ceSctpStatT1expired
OID (numeric): 1.3.6.1.4.1.9.10.74.1.1.25
Node type: OBJECT-TYPE
Type: Counter32
Access: read-only
Description: Number of times that T1 timer expired (timer for sending either INIT or COOKIE-ECHO chunks and receiving an acknowledgment).
What is ceSctpStatT1expired?
This counter tracks how many times the T1 timer, which bounds how long the device waits for acknowledgment of an INIT or COOKIE-ECHO chunk, expired. Repeated T1 expirations mean association setup handshakes are stalling, which on a signaling gateway directly delays or prevents a new SS7 or SIGTRAN link from coming up. This counter increasing specifically whenever one peer tries to establish a new association suggests that peer, or the path to it, is not responding to INIT or COOKIE-ECHO in time.
