tnPortSpeedCurrent

Module: TN-PORT-MIB

OID (symbolic): TN-PORT-MIB::tnPortSpeedCurrent

OID (numeric): 1.3.6.1.4.1.868.2.5.141.1.1.1.2

Node type: OBJECT-TYPE

Type: INTEGER

Access: read-only

Description: Provides the current link speed of the port. Unknown - Link down. 10Mbps HDX - Forces the port in 10Mbps half duplex mode. 10Mbps FDX - Forces the port in 10Mbps full duplex mode. 100Mbps HDX - Forces the port in 100Mbps half duplex mode. 100Mbps FDX - Forces the port in 100Mbps full duplex mode. 1Gbps FDX - Forces the port in 1Gbps full duplex mode. 2.5Gbps FDX - Forces the port in 2.5Gbps full duplex mode 10Gbps FDX - Forces the port in 10Gbps full duplex mode.

What is tnPortSpeedCurrent?

This read-only INTEGER reports the link speed and duplex mode actually in effect on this port right now, ranging from unknown(1) when the link is down to specific values like fdx1Gbps(6) or fdx10Gbps(8). An admin checks it to confirm what speed a port actually negotiated to, which may differ from what tnPortSpeedConfigured requested if auto-negotiation settled on something else. Seeing tnPortSpeedCurrent report fdx100mbps(5) when the admin expected Gigabit would indicate an auto-negotiation mismatch with the connected device worth investigating.
