1636 ExtremeWare Software 7.3.0 Command Reference Guide
PoS Commands
configure aps timers
configure aps <group#> timers <seconds> <consecutive_misses>
Description
Sets the values of the timers used in the APS hello protocol that is exchanged between the working and
protection switches for an APS group.
Syntax Description
Default
The default values are
seconds
= 1 and
consecutive_misses
= 5. These parameters are only applicable
to SONET ports performing the protection line function.
Usage Guidelines
You specify the
group#
parameter, which is an integer in the range [1-65535]. The
group#
identifies the
APS group that the configuration command applies to. The
seconds
parameter is an integer in the
range [1-300] that specifies the amount of time the protection switch waits between transmissions of
hello packets to the working switch. The
consecutive_misses
parameter is an integer in the range
[1-100] that controls the time interval the protection switch will wait before assuming that the working
switch has failed. If the working switch does not respond within
consecutive_misses
hello intervals,
or (
consecutive_misses
*
seconds
) seconds, then the protection switch assumes that the working
switch has failed and initiates a line switch.
Example
The following command example configures the timers for APS group
1001
to
1
second and
3
consecutive misses:
config aps 1001 timers 1 3
