circuitSrcSidePort

Module: FRX-MIB

OID (symbolic): FRX-MIB::circuitSrcSidePort

OID (numeric): 1.3.6.1.4.1.177.3.4.2.1.28

Node type: OBJECT-TYPE

Type: INTEGER

Access: read-only

Description: A circuit segment within an FRX node has two endpoints, each identified by a (port,DLCI) pair. This variable is the source side port number. Note: A value of -1 means 'not applicable'. This variable is not applicable unless the PVC state is Complete.

What is circuitSrcSidePort?

Identifies the port number at the source-side endpoint of this circuit segment within the node -- a PVC segment has two (port,DLCI) endpoints internally; the value is only meaningful once the PVC's state is Complete, and reads -1 otherwise.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.177.3.4.2.1.28
snmpwalk -v2c -c public <target> FRX-MIB::circuitSrcSidePort

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.177.3.4.2.1.28.1
snmpget -v2c -c public <target> FRX-MIB::circuitSrcSidePort.1
