Configuring basic system parameters
2
To change the holddown time for SNMP traps, enter a command such as the following at the global
CONFIG level of the CLI.
PowerConnect(config)# snmp-server enable traps holddown-time 30
The command in this example changes the holddown time for SNMP traps to 30 seconds. The
device waits 30 seconds to allow convergence in STP and OSPF before sending traps to the SNMP
trap receiver.
Syntax: [no] snmp-server enable traps holddown-time <secs>
The <secs> parameter specifies the number of seconds and can be from 1 – 600 (ten minutes).
The default is 60 seconds.
