gsESwitchPortTrunkingMode

Module: GIGAswitchEthernet-MIB

OID (symbolic): GIGAswitchEthernet-MIB::gsESwitchPortTrunkingMode

OID (numeric): 1.3.6.1.4.1.36.2.18.39.5.2.1.1.9

Node type: OBJECT-TYPE

Type: INTEGER

Access: read-write

Description: The trunking mode of this port. All frames transmitted out this switch port are translated to the appropriate trunking format:

Clear: Ethernet or IEEE 802.3 frame format. This is the default. IEEE 802.1Q: The original frame with a new Ethernet Type (Protocol = 0xXXXX) and the VLAN ID inserted following the original Source Address. Also, the CRC is recalculated.

What is gsESwitchPortTrunkingMode?

Sets the trunking frame format used when the switch sends frames out this port: clear(1) (the default) uses plain Ethernet/802.3 framing, while ieee8021q(2) inserts an 802.1Q Ethernet Type and VLAN ID after the source address and recalculates the CRC. Admins set ieee8021q(2) on a port trunking to another VLAN-aware switch.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.36.2.18.39.5.2.1.1.9
snmpwalk -v2c -c public <target> GIGAswitchEthernet-MIB::gsESwitchPortTrunkingMode

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.36.2.18.39.5.2.1.1.9.1
snmpget -v2c -c public <target> GIGAswitchEthernet-MIB::gsESwitchPortTrunkingMode.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.36.2.18.39.5.2.1.1.9.1 i <value>
