ctAutoNegAdminStatus
Module: CTRON-ETHERNET-PARAMETERS-MIB
OID (symbolic): CTRON-ETHERNET-PARAMETERS-MIB::ctAutoNegAdminStatus
OID (numeric): 1.3.6.1.4.1.52.4.1.2.4.2.1.1.1.1
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-write
Description: This object controls whether Auto-Negotiation is enabled for the specified port. If Auto-Negotiation is disabled the port will revert to the speed, duplex and flow control settings specified by their associated leaves in the ctEtherManualConfig and ctFlowControl groups.
What is ctAutoNegAdminStatus?
This is an administrative toggle enabling or disabling IEEE Auto-Negotiation on this specific Ethernet port. When disabled, the port falls back to the manually configured speed, duplex, and flow-control settings defined elsewhere in this MIB. For example, an admin disables auto-negotiation on a port connected to an older switch that mis-negotiates, forcing it instead to a manually set 100Mb full-duplex configuration.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.52.4.1.2.4.2.1.1.1.1 snmpwalk -v2c -c public <target> CTRON-ETHERNET-PARAMETERS-MIB::ctAutoNegAdminStatus
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.52.4.1.2.4.2.1.1.1.1.1 snmpget -v2c -c public <target> CTRON-ETHERNET-PARAMETERS-MIB::ctAutoNegAdminStatus.1
Set instance 1 (SNMPv2c):
snmpset -v2c -c private <target> 1.3.6.1.4.1.52.4.1.2.4.2.1.1.1.1.1 i <value>
