This command is not valid for S8700 IP Connect configurations.

The test fiber-link command validates that the optical fiber connection between

switch node interfaces (SNI) and expansion interfaces (EI), or a combination

thereof, are administered. If the fiber link is administered, a series of hardware

diagnostic tests are performed on the specified fiber link. The test results along

with any possible error codes are displayed on the MT. The long test sequence

includes destructive tests. Every destructive test aborts unless the fiber link is first

busied out. The short test sequence is non-destructive and can be performed

regardless of whether the fiber link is busied out.

A fiber link is a connection between port networks (PNs), switch nodes (SNs), or

between a PN and the Center Stage Switch (CSS). This connection is comprised

of a bi-directional optical fiber connection (optionally extended via a DS1

Converter complex), with each end terminated on either an Expansion Interface

(EI) or a Switch Node Interface (SNI). Fiber links provide the medium for circuit

and packet connections between PNs and for communication between the EPNs.

The long sequence includes destructive tests and requires that the fiber link be

busied out first. When a fiber is busied out, every call over that fiber is dropped.

clear firmware-counters clears the firmware counters of specified SNI, SNC,

ATM-EI or DS1C circuit packs, or of an the entire PNC (A or B).

The number associated with a fiber link or fiber link pair (on duplicated PNCs).

List fiber-link displays the location of endpoints for each fiber link.

a-pnc | b-pnc

On critical-reliability systems (duplicated PNC) this identifier is used to distinguish

between the two fibers of a duplicated fiber pair.
