Module: RFC1286-MIB

OID (symbolic): RFC1286-MIB::dot1dSrPortBridgeNum

OID (numeric): 1.3.6.1.2.1.17.3.1.1.4

Node type: OBJECT-TYPE

Type: INTEGER

Access: read-write

Description: A bridge number uniquely identifies a bridge when more than one bridge is used to span the same two segments. Current source routing protocols limit this value to the range: 0 through 15. A value of 65535 signifies that no bridge number is assigned to this bridge.

What is dot1dSrPortBridgeNum?

This object holds the bridge number that uniquely identifies this bridge when more than one bridge spans the same two segments, with 65535 meaning no bridge number is assigned. Admins set this when parallel bridges exist between two segments, so source-routed frames can distinguish which bridge instance forwarded them. For example, two bridges linking the same pair of rings might be numbered 1 and 2 respectively.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.2.1.17.3.1.1.4
snmpwalk -v2c -c public <target> RFC1286-MIB::dot1dSrPortBridgeNum

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.2.1.17.3.1.1.4.1
snmpget -v2c -c public <target> RFC1286-MIB::dot1dSrPortBridgeNum.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.2.1.17.3.1.1.4.1 i <value>
