DESCRIPTION

DEFAULT

HLXR NID Loopback

UNIT SWITCH

Version E HLXR only: Selects

MPU V5.1:

 

 

 

NID setting (enabled) for the

UNIT SWITCH

 

 

 

HLXR.

MPU V5.2:

 

 

 

 

 

 

 

Version D or earlier HLXR:

ENABLED

 

 

 

Selects NID setting (either enabled

 

 

 

 

[default] or disabled) on the HLXR.

 

 

 

 

When the HLXR is provisioned to

 

 

 

 

function like an NID, it supports

 

 

 

 

inband and out-of-band loopback

 

 

 

 

codes.

 

 

 

 

 

 

 

 

ENABLED

Enables response to NID loopback

 

 

 

 

codes and overrides hardware

 

 

 

 

configuration settings.

 

 

 

 

 

 

 

 

DISABLED

Disables response to NID loopback

 

 

 

 

codes and overrides hardware

 

 

 

 

configuration settings.
