addapsln
Note Other architecture mode options may be displayed by the CLI when the addapsln command is entered
with no parameters, but they are not supported at this time.
AXSM/A and AXSM/B APS Issues
AXSM PXM45-based software has two different operating modes:
• AXSM-A mode
• AXSM-B mode
Note To see the APS mode of an AXSM, run dspcd on the CLI of the AXSM. The field labeled “Card
Operating Mode” shows either AXSM-A or AXSM-B.
AXSM PXM1-based cards and below have only the AXSM-A mode. AXSM PXM45-based cards have
both AXSM-A and AXSM-B modes.
When you upgrade from a PXM1-based switch to a PXM45-based switch, the AXSM will still be in
AXSM-A mode. To change to AXSM-B mode, use the PXM command, enableaxsmbaps from the PXM
CLI. Refer to Cisco MGX 8800/8900 Series Configuration Guide, Release 5.2.
AXSM-A mode monitors only one line at a time. AXSM-B monitors two lines at the same time.
AXSM/B cards can run in either the AXSM-A or AXSM-B mode.
When using two AXSM/A cards for an APS redundant pair, if one of the AXSM/A cards does not
function in the intercard state, the AXSM-A mode will not function. AXSM/A transmits RDI on both
the working and protection lines.
When using two AXSM/B cards for an APS redundant pair, if one of the AXSM/B cards does not
function in the intercard state, APS is unaffected.
For APS to function properly on AXSM/B, AXSM-E, and AXSM-XG, at least one front card and its back
card must be functioning properly. However, signal failure will be reported from all lines on the other
back card if the other back card is not present.
