bertLoopbackMask

Module: CISCO-WAN-AXIPOP-MIB

OID (symbolic): CISCO-WAN-AXIPOP-MIB::bertLoopbackMask

OID (numeric): 1.3.6.1.4.1.351.110.6.1.28.1.7

Node type: OBJECT-TYPE

Type: INTEGER

Access: read-only

Description: Every loopback is represented by 2 bits of mask. Bits 0-5 are
valid in this integer. The meaning of the mask can be 
understood from the example below:
   ----------------------------------------------
        Loopback     |   SM       |  Test Medium
                     | support    |     Port
   ----------------------------------------------
   Far End Loopback  |     1      |    1
   Facility Loopback |     1      |    1
   Metallic Loopback |     1      |    0
   ----------------------------------------------
   (Table contents applicable to FRSM-4T1)
   bertLoopbackMask = 011111 binary

The column titles represent the variables bertLoopback  
depends on. The mask is represented in column major order.
             

What is bertLoopbackMask?

This read-only object is a bitmask (bits 0-5 valid, 2 bits per loopback type) indicating which loopback types -- far end, facility, or metallic -- are supported by the Service Module in this slot, cross-referenced against supported test media like port. An admin choosing a bertLoopback value would decode this mask to confirm the specific loopback type is valid for the card and test medium being used. This is another card-capability check an admin's automation would perform before issuing the actual loopback SET.
