ieee8021AsPortStatTxFollowUpCount

Module: IEEE8021-AS-MIB

OID (symbolic): IEEE8021-AS-MIB::ieee8021AsPortStatTxFollowUpCount

OID (numeric): 1.3.111.2.802.1.1.20.1.6.1.12

Node type: OBJECT-TYPE

Type: Counter32

Access: read-only

Description: A counter that increments every time a Follow_Up message is transmitted, denoted by a transition to TRUE from FALSE of the rcvdMDTimestampReceive variable of the MDSyncSendSM state machine (see 11.2.14.1.3 and Figure 11-7), when in the SEND_SYNC state increments every time a Follow_Up packet is transmitted.

What is ieee8021AsPortStatTxFollowUpCount?

A counter of Follow_Up messages transmitted from this port, each carrying the precise timestamp for a Sync message just sent. Should track Tx Sync Count closely on a master port; a gap between the two indicates timestamping problems.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.111.2.802.1.1.20.1.6.1.12
snmpwalk -v2c -c public <target> IEEE8021-AS-MIB::ieee8021AsPortStatTxFollowUpCount

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.111.2.802.1.1.20.1.6.1.12.1
snmpget -v2c -c public <target> IEEE8021-AS-MIB::ieee8021AsPortStatTxFollowUpCount.1
