swIfAutoNegotiationMasterSlavePreference

Module: CISCOSB-rlInterfaces

OID (symbolic): CISCOSB-rlInterfaces::swIfAutoNegotiationMasterSlavePreference

OID (numeric): 1.3.6.1.4.1.9.6.1.101.43.1.1.45

Node type: OBJECT-TYPE

Type: INTEGER

Access: read-write

Description: This variable specifies the administrative mode of the Maste-Slave preference in auto negotiation.

What is swIfAutoNegotiationMasterSlavePreference?

This read-write enumerated INTEGER (preferMaster/preferSlave) sets the administrative master/slave role preference used during auto-negotiation on this interface, relevant to clock-timing negotiation on certain Ethernet link types like 1000BASE-T. Admins configure this when a link fails to negotiate properly, since both ends need complementary master/slave roles for clock recovery to work. For example, if two directly connected gigabit ports both default to the same role and fail to link up, setting one side to preferSlave can resolve the negotiation deadlock.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.9.6.1.101.43.1.1.45
snmpwalk -v2c -c public <target> CISCOSB-rlInterfaces::swIfAutoNegotiationMasterSlavePreference

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.9.6.1.101.43.1.1.45.1
snmpget -v2c -c public <target> CISCOSB-rlInterfaces::swIfAutoNegotiationMasterSlavePreference.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.9.6.1.101.43.1.1.45.1 i <value>
