ieee8021AsPortStatTxAnnounce

Module: IEEE8021-AS-MIB

OID (symbolic): IEEE8021-AS-MIB::ieee8021AsPortStatTxAnnounce

OID (numeric): 1.3.111.2.802.1.1.20.1.6.1.16

Node type: OBJECT-TYPE

Type: Counter32

Access: read-only

Description: A counter that increments every time an Announce message is transmitted, denoted by entering the TRANSMIT_ANNOUNCE state of the PortAnnounceReceive state machine (see 10.3.13 and Figure 10-15).

What is ieee8021AsPortStatTxAnnounce?

A counter of Announce messages transmitted from this port. On a port acting as master, this should be climbing at the configured announce interval; a stall means downstream neighbors have stopped receiving grandmaster candidacy info from this port.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.111.2.802.1.1.20.1.6.1.16
snmpwalk -v2c -c public <target> IEEE8021-AS-MIB::ieee8021AsPortStatTxAnnounce

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.111.2.802.1.1.20.1.6.1.16.1
snmpget -v2c -c public <target> IEEE8021-AS-MIB::ieee8021AsPortStatTxAnnounce.1
