Signal failure (SF) and signal degrade (SD) alarms are not enabled by default on POS interfaces. It is
recommended to change the default alarm notification configuration for POS ports that belong to APS
groups in order to be notified of SF/SD occurrences to be able to interpret the cause for an APS group to
switch the active line.
For path alarms, modify the logical line aps-id in the configure port aps-id sonet-sdh path
alarm
For line alarms, separately, modify the 2 physical ports that are members of the logical aps-id port (the
working and protect lines). APS reacts only to line alarms, not path alarms.
For example:
For example:
A:ALA-48>config>port>aps# info

A:ALA-48>config>port>aps#
If the SD and SF
both the working and protect APS port member.
The no form of this command deletes an aps-group-id or bundle-aps-group-id. In order for an aps-
group-id to be deleted,
The same rules apply for physical ports, bundles deletions apply to APS ports/bundles deletions (for
example an aps-group-id must be shutdown, have no service configuration on it, and no path
configuration on it). In addition working and protection circuits must be removed before an aps-group-
id may be removed.
