psmLinkState
Module: COMPEX-IN3000
OID (symbolic): COMPEX-IN3000::psmLinkState
OID (numeric): 1.3.6.1.4.1.426.1.7.3.1.5
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-only
Description: The link state of the port.
Note that if link pulses are disabled then the link state will be up.
What is psmLinkState?
This read-only enumerated value reports whether a specific port currently shows up(1), down(2), or unsupported(3) link status, noting that the value reads up if link pulses are disabled on that port. An admin uses it as the first check when a host on that port seems unreachable, to distinguish a physical disconnect from a higher-layer problem. Seeing psmLinkState down(2) on port 5 while the cable appears seated would prompt an admin to check psmLinkPulses to rule out link-pulse detection being disabled.
