scEthPortMode

Module: XSWITCH-MIB

OID (symbolic): XSWITCH-MIB::scEthPortMode

OID (numeric): 1.3.6.1.4.1.81.28.2.1.1.1.28

Node type: OBJECT-TYPE

Type: INTEGER

Access: read-write

Description: The flow control mode of the port when operated in full duplex: halfDuplex(1) - Half duplex connection, standard mode for segment fullDuplexNoPause(2) - Full duplex connection without exchanging flow control packets fullDuplexProprietaryFC(3) - Full duplex connection with Lucent's proprietary flow control frames exchanged fullDuplexISL(4) - Full duplex connection with ISL proprietary protocol control words for VLAN & priority exchanged, ISL = Inter-Switch-Link fullDuplexFlowControlISL(5) - Full duplex connection with both ISL proprietary protocol control words and flow control frames exchanged fullDuplexAsymTxPause(6) - Full duplex connection with STD 802.3x flow control frames sent from this port, but flow control packets received on it are not processed fullDuplexSymPause(7) - Full duplex connection with STD 802.3x flow control frames exchanged fullDuplexAsymRxPause(8) - Full duplex connection with no flow control frames sent from this port, but STD 802.3x flow control 0frames received on it are processed. For Giga ports, when auto-negotiation is enabled, the flow control mode is set internally according to auto-negotiation resolution; and access to this item is read-only.

What is scEthPortMode?

Selects the port's duplex and flow-control behavior: halfDuplex(1) for standard shared-segment operation, or one of several full-duplex variants that add Lucent proprietary flow control, ISL inter-switch-link tagging, or standard 802.3x pause frames in symmetric or asymmetric (Tx-only/Rx-only) form; on Gigabit ports with auto-negotiation enabled this becomes read-only since the mode is resolved automatically.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.81.28.2.1.1.1.28
snmpwalk -v2c -c public <target> XSWITCH-MIB::scEthPortMode

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.81.28.2.1.1.1.28.1
snmpget -v2c -c public <target> XSWITCH-MIB::scEthPortMode.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.81.28.2.1.1.1.28.1 i <value>
