corePortSpeed
Module: CORE-MIB
OID (symbolic): CORE-MIB::corePortSpeed
OID (numeric): 1.3.6.1.4.1.629.1.50.9.3.1.12
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-only
Description: Actual speed in Mbps
What is corePortSpeed?
This read-only INTEGER reports the port's actual negotiated speed in Mbps. An admin uses it to confirm a port actually negotiated the expected link speed rather than falling back to a lower rate. For example, an admin sees corePortSpeed=100 when 1000 was expected and investigates a bad cable or SFP causing the port to negotiate down.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.629.1.50.9.3.1.12 snmpwalk -v2c -c public <target> CORE-MIB::corePortSpeed
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.629.1.50.9.3.1.12.1 snmpget -v2c -c public <target> CORE-MIB::corePortSpeed.1
