adnChassisBackupMSC8kSourceIfIndex
Module: ADN-MIB
OID (symbolic): ADN-MIB::adnChassisBackupMSC8kSourceIfIndex
OID (numeric): 1.3.6.1.4.1.637.3.1.5.15.1.1.8
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-only
Description: This variable identifies the backup line timing source . In spite of the name, which is like this for historical reasons, the line timing source can be MSC (Medium Speed Coupler) 8kHz, PDH HSC (High Speed Coupler) or SDH HSC line timing source. The value of this object corresponds to the ifIndex of the line which provides the source. The value 0 is used when there is no backup line timing source located on the chassis.
What is adnChassisBackupMSC8kSourceIfIndex?
This OID stores an interface index number that points to the card providing backup timing signals (8 kHz, PDH, or SDH) to the chassis. Network engineers care about this because if the primary timing source fails, the system automatically switches to this backup, and knowing which interface is the backup helps verify redundancy is properly configured. An example value might be 5, meaning port 5 on the chassis is currently the backup timing source; a value of 0 means no backup timing source is configured.
