ieee8021AsPortDSPortRole

Module: IEEE8021-AS-MIB

OID (symbolic): IEEE8021-AS-MIB::ieee8021AsPortDSPortRole

OID (numeric): 1.3.111.2.802.1.1.20.1.5.1.5

Node type: OBJECT-TYPE

Type: INTEGER

Access: read-only

Description: The value is the value of the port role of this port (see Table 10-1), and is taken from the enumeration in Table 14-5. All other values reserved. The enumeration values are consistent with IEEE Std 1588TM-2008, Table 8. The default value is 3 (DisabledPort).

What is ieee8021AsPortDSPortRole?

The port's current role in the gPTP spanning tree: disabledPort, masterPort, passivePort, or slavePort. Check this to see whether a given port is actively distributing time downstream (master), receiving it from upstream (slave), or excluded from the timing topology (disabled/passive).

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.111.2.802.1.1.20.1.5.1.5
snmpwalk -v2c -c public <target> IEEE8021-AS-MIB::ieee8021AsPortDSPortRole

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.111.2.802.1.1.20.1.5.1.5.1
snmpget -v2c -c public <target> IEEE8021-AS-MIB::ieee8021AsPortDSPortRole.1
