Unable To Set Up Aps 1:1 Line Redundancy Configuration; Operator Information About Aps Architectures - Cisco BPX-BXM-155-8DX Installation And Configuration Manual

APS Configuration Problems
Initial Investigation: The addapsln command is used to setup the APS line redundancy configuration.
For APS 1+1 configurations, BPX software supporting APS and BXM firmware supporting APS must
be used.
These hardware requirements must be met:

Unable to set up APS 1:1 line redundancy configuration

Description: The addapsln user interface command fails to execute correctly for APS 1:1 line addition.
Initial Investigation: For APS 1:1 configuration, two adjacent lines on the same card are used. No
special hardware is required however the maximum connections supported must be reduced by half
using the cnfcdaps command. FW and SW support of APS is required.
Workaround: APS 1:1 can be run on non APS enhanced BXM card by halving the number of channels
the card can support (cnfcdaps). No special backcards are needed for APS 1:1.
For APS 1:1 configuration the APS line must be configured (addapsln) before a line (upln) or trunk
(uptrk) can be upped. Conversely, the line or trunk must be downed before the APS line can be deleted
(delapsln).
Use dspapsln to verify that the APS line has been added.

Operator information about APS architectures

Description: The cnfapsln user interface command does not let you configure any combination of APS
architectures.
Initial Investigation: You can change the APS configuration by using the cnfapsln command, however
not all combinations are allowed. Here is a table of combinations allowed and disallowed.

BXM-Enhanced OC-3 or OC-12 front cards. BXM -155-4 or BXM-155-8 frontcard of revision C
or higher. BXM-622-2 or BXM-622-1 of revision E or higher.
RDNT-BP daughter backplane - special APS redundancy backplane
BXM OC-3 or OC-12 APS backcards (they have two connectors on the back instead of one and
require the daughter backplane in order to fit into the BPX backframe.
Card redundancy (addcdred or addyred) must be set up on the card pair prior to addapsln, see
section on Y-cable issues. APS does not use the special Y-cable, it uses straight cables on both ports
to the remote port. The redundant card must be in adjacent slots.
Using a backcard frame containing internal card cage stiffeners requires that only slots 2-5 and
10-13 be used for APS 1+1 configurations. This is due to the stiffeners preventing the daughter
backplane from fitting into the backcard frame.
A newer backcard frame removes the slot restriction of having to put daughter backplane and APS
backcards in slots 2-5 and 10-13.
