ieee8021AsPortDSPortNumber

Module: IEEE8021-AS-MIB

OID (symbolic): IEEE8021-AS-MIB::ieee8021AsPortDSPortNumber

OID (numeric): 1.3.111.2.802.1.1.20.1.5.1.4

Node type: OBJECT-TYPE

Type: Unsigned32

Access: read-only

Description: The portNumber value for a port on a time-aware end station (i.e., a time-aware system supporting a single gPTP port) shall be 1. The portNumber values for the gPTP ports on a time-aware bridgeBridge supporting N ports shall be 1, 2, ?, N, respectively (see 8.5.2.3) .

What is ieee8021AsPortDSPortNumber?

The gPTP port number for this row, always 1 on a single-port end station, or 1..N on an N-port bridge. Use it together with the clock identity to uniquely address a specific timing port when reading other port-level counters.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.111.2.802.1.1.20.1.5.1.4
snmpwalk -v2c -c public <target> IEEE8021-AS-MIB::ieee8021AsPortDSPortNumber

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.111.2.802.1.1.20.1.5.1.4.1
snmpget -v2c -c public <target> IEEE8021-AS-MIB::ieee8021AsPortDSPortNumber.1
