dot1dSrPortLocalSegment

Module: SOURCE-ROUTING-MIB

OID (symbolic): SOURCE-ROUTING-MIB::dot1dSrPortLocalSegment

OID (numeric): 1.3.6.1.2.1.17.3.1.1.3

Node type: OBJECT-TYPE

Type: INTEGER

Access: read-write

Description: The segment number that uniquely identifies the segment to which this port is connected. Current source routing protocols limit this value to the range: 0 through 4095. (The value 0 is used by some management applications for special test cases.) A value of 65535 signifies that no segment number is assigned to this port.

What is dot1dSrPortLocalSegment?

The segment number, 0-4095 with 65535 meaning unassigned, identifying the LAN segment this port connects to, a key piece of the source-routing topology an admin configures for the bridge to function correctly.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.2.1.17.3.1.1.3
snmpwalk -v2c -c public <target> SOURCE-ROUTING-MIB::dot1dSrPortLocalSegment

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.2.1.17.3.1.1.3.1
snmpget -v2c -c public <target> SOURCE-ROUTING-MIB::dot1dSrPortLocalSegment.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.2.1.17.3.1.1.3.1 i <value>
