exNetPortLinkStatus

Module: DAVID-MIB

OID (symbolic): DAVID-MIB::exNetPortLinkStatus

OID (numeric): 1.3.6.1.4.1.66.1.3.2.3.1.1.3

Node type: OBJECT-TYPE

Type: INTEGER

Access: read-only

Description: For 10BASE-T ports: this is the link integrity test defined by the 10BASE-T standard. If link status test is enabled, this flag indicates whether the link is active or inactive. There are several reasons for an inactive link: . PC or workstation connected to the MAU has been turned off . disrupted link (e.g., wiring problem) . TP-MAU on the end of the link is missing, dead, or powered off . transmit and receive polarities are swapped

For FOIRL ports: the link status is constantly tested; thus, this variable is always meaningful. A value of off(1) indicates a low-light condition (poor signal quality). The value on(2) indicates that signal quality on the link is ok.

For AUI ports: the value other(3) is always returned since link status test does not apply.

What is exNetPortLinkStatus?

Reports link integrity for this port: for 10BASE-T ports it reflects the standard link-integrity test (off(1) can mean a powered-down device, bad wiring, a dead MAU, or swapped polarity); for FOIRL ports off(1) indicates low light / poor signal quality; AUI ports always report other(3) since the test doesn't apply to them.
