sonusApsGroupChannelMismatches

Module: SONUS-SONET-APS-MIB

OID (symbolic): SONUS-SONET-APS-MIB::sonusApsGroupChannelMismatches

OID (numeric): 1.3.6.1.4.1.2879.2.5.9.1.2.1.16

Node type: OBJECT-TYPE

Type: Counter32

Access: read-only

Description: A count of Channel Mismatch failures. A Channel Mismatch indicates that a mismatch between the transmitted K1 channel and the received K2 channel has been detected. Under normal conditions, a mismatch will occure each time the LTE changes the channel number on its transmitted K1 byte (i.e., when the channel with the highest priority switch request changes). A mismatch could also occur if the channel number on the incoming K2 byte changes (e.g., due to a failure at the far-end LTE).

What is sonusApsGroupChannelMismatches?

Read-only Counter32 counting Channel Mismatch events, where the transmitted K1 channel and received K2 channel disagree; some mismatches are normal during a switch, but a persistently rising count suggests a far-end problem.
