Chapter 7 Switch Operating Procedures
Managing Redundant APS Lines
If you want to manually switch from one line to another, enter the switchapsln <bay> <line>
<switchOption> command, as shown in the following example:
M8850_LA.1.AXSM.a > switchapsln 1 1 6
Manual line switch from protection to working succeeded on line 1.1.1
Table 7-5 describes the configurable parameters for the switchapsln command.
-dr <direction> Determines whether the line is unidirectional or
bidirectional.
• 1 = Unidirectional. The line switch occurs at the receive
end of the line.
• 2 = Bidirectional. The line switch occurs at both ends of
the line.
Note This optional parameter is not shown in the above
example because you do not need to set it for a
revertive line.
Example:
-dr 2
-rv <revertive> Determines whether the line is revertive or non-revertive.
• 1 = Non-revertive. You must manually switch back to a
recovered working line.
• 2 = Revertive. APS automatically switches back to a
recovered working line after the number of minutes set in
the -wtr parameter.
Example:
-rv 1
