What is nwAppnFwdLsNumActiveSession?

This read-only integer reports the total number of active sessions currently on this specific link, counting both endpoint sessions and intermediate (transit) sessions together. An admin uses this to gauge real-time load on a particular link, and a value near a known session limit warns of impending congestion on just that link. An admin planning to take a link down for maintenance would check this counter first to see how many active sessions would be disrupted.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.52.4.2.2.2.3.5.2.2.3.1.1.1.27
snmpwalk -v2c -c public <target> CTRON-APPN-MIB::nwAppnFwdLsNumActiveSession

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.52.4.2.2.2.3.5.2.2.3.1.1.1.27.1
snmpget -v2c -c public <target> CTRON-APPN-MIB::nwAppnFwdLsNumActiveSession.1
