The lifetime of every trap message depends on the number of generated trap messages. If
the switch frequently generates trap messages, a longer lifetime can be set for every trap
message to prevent trap messages from being lost.
Configuring inform parameters
:
1.
Run:
snmp-agent inform
{
timeout
seconds
|
resend-times
times
|
pending
number
}
*
The timeout period for waiting for Inform ACK messages, number of inform
retransmissions, and allowable maximum number of informs to be acknowledged are set.
If the network is unstable, you need to specify the number of inform retransmissions and
allowable maximum number of informs to be acknowledged when you set a timeout period
for waiting for Inform ACK messages. By default, the timeout period for waiting for Inform
ACK messages is 15 seconds; the number of inform retransmissions is 3; the allowable
maximum number of informs waiting to be acknowledged is 39.
Setting the number of inform retransmissions to a value smaller than or equal to 10 is
recommended. Otherwise, device performance will be affected.
2.
Run:
snmp-agent inform
{
timeout
seconds
|
resend-times
times
}
*
address
udp-
domain
ip-address
params
securityname
security-string
The timeout period for waiting for Inform ACK messages from a specified NM station and
the number of inform retransmissions are set.
If the network is unstable, you need to specify the number of inform retransmissions and
allowable maximum number of informs to be acknowledged when you set a timeout period
for waiting for Inform ACK messages. By default, the timeout period for waiting for Inform
ACK messages is 15 seconds, and the number of inform retransmissions is 3.
Setting the number of inform retransmissions to a value smaller than or equal to 10 is
recommended. Otherwise, device performance will be affected.
3.
Run:
snmp-agent notification-log enable
The alarm logging function is enabled.
If the link between the switch and the NM station fails, the switch will stop sending informs
to the NM station because the NM station is unroutable but the switch will continue logging
informs. If the link recovers, the NM station will learn the informs logged by the switch
during the link failure.
After the alarm logging function is enabled, the system logs only informs, not traps.
By default, the alarm logging function is disabled.
4.
Run:
snmp-agent notification-log
{
global-ageout
ageout
|
global-limit
limit
}
*
The aging time of alarm logs and maximum number of alarm logs allowed to be stored in
the log buffer are set.
By default, the aging time of alarm logs is 24 hours. If the aging time expires, alarms logs
will be automatically deleted.
