Trap:
In the switch, there are 6 trap hosts supported. Each of them has its own
community name and IP address; is user-definable. To set up a trap host
means to create a trap manager by assigning an IP address to host the
trap message. In other words, the trap host is a network management unit
with SNMP manager receiving the trap message from the managed switch
with SNMP agent issuing the trap message. 6 trap hosts can prevent the
important trap message from losing.
For each public trap, the switch supports the trap event Cold Start, Warm
Start, Link Down, Link Up and Authentication Failure Trap. They can be
enabled or disabled individually. When enabled, the corresponded trap will
actively send a trap message to the trap host when a trap happens. If all
public traps are disabled, no public trap message will be sent. As to the
Enterprise (no. 6) trap is classified as private trap, which are listed in the
Trap Alarm Configuration function folder.
Default for all public traps: Enable.
