gsEPortMirroringSourceSubPort

Module: GIGAswitchEthernet-MIB

OID (symbolic): GIGAswitchEthernet-MIB::gsEPortMirroringSourceSubPort

OID (numeric): 1.3.6.1.4.1.36.2.18.39.5.5.1.1.2

Node type: OBJECT-TYPE

Type: INTEGER

Access: read-write

Description: The frame sampler source switch subport. The source port is the port from which received traffic will be mirrored. This object identifies the switch subport only, the switch fabric port is identified in gsEPortMirroringIndex. If set to 0, all subports associated with the gsEPortMirroringIndex will be source ports. The default value is 0.

What is gsEPortMirroringSourceSubPort?

Specifies which sub-port under this mirroring session's fabric port is the traffic source to mirror; 0 (the default) means all subports on that fabric port are mirrored. Admins narrow this to one specific subport when they only want to capture one physical port's traffic rather than an entire multi-port fabric group.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.36.2.18.39.5.5.1.1.2
snmpwalk -v2c -c public <target> GIGAswitchEthernet-MIB::gsEPortMirroringSourceSubPort

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.36.2.18.39.5.5.1.1.2.1
snmpget -v2c -c public <target> GIGAswitchEthernet-MIB::gsEPortMirroringSourceSubPort.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.36.2.18.39.5.5.1.1.2.1 i <value>
