ieee8021AsPortStatRxFollowUpCount

Module: IEEE8021-AS-MIB

OID (symbolic): IEEE8021-AS-MIB::ieee8021AsPortStatRxFollowUpCount

OID (numeric): 1.3.111.2.802.1.1.20.1.6.1.2

Node type: OBJECT-TYPE

Type: Counter32

Access: read-only

Description: A counter that increments every time a Follow_Up message is received, denoted by a transition to TRUE from FALSE of the rcvdFollowUp variable of the MDSyncReceiveSM state machine (see 11.2.13.1.3 and Figure 11-6) when in the WAITING_FOR_FOLLOW_UP state.

What is ieee8021AsPortStatRxFollowUpCount?

A counter of Follow_Up messages received on this port, each of which carries the precise timestamp for a preceding Sync message. If Rx Sync count climbs but this stays flat, Follow_Up messages are being lost or dropped.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.111.2.802.1.1.20.1.6.1.2
snmpwalk -v2c -c public <target> IEEE8021-AS-MIB::ieee8021AsPortStatRxFollowUpCount

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.111.2.802.1.1.20.1.6.1.2.1
snmpget -v2c -c public <target> IEEE8021-AS-MIB::ieee8021AsPortStatRxFollowUpCount.1
