Command Modes APS configuration
Command History
Usage Guidelines The holddown timer prevents APS Channel Protocol message flooding over the OSC. The holddown
message count allows a specified number of messages to exchange between the nodes before the
holddown timer starts. For example, if the holddown message count is set to 2, the node sends and
receives two messages before the timer starts. This allows the protocol to operate efficiently without
affecting system performance.
Note The default values for the holddown timer and message count are sufficient for most network
configurations.
Examples The following example shows how to modify the holddown timer and count values.
Switch(config)# redundancy
Switch(config-red)# associate group denver
Switch(config-red-aps)# aps disable
Switch(config-red-aps)# aps timer message holddown 4000 count 4
Switch(config-red-aps)# aps enable
milliseconds Specifies the number of seconds to wait before sending an APS Channel
Protocol message. The range is 100to 10,000 milliseconds. The default
timer interval is 5000 milliseconds (5seconds).
count number Specifies the number of messages to send to the destination node before
starting the hold-down timer. The range is 2to 10. The default message
count is 2.
