Configuring Traps
This section provides information for:
â– IP Hosts on page 167
â– Trap Categories on page 168
â– Trap Severity Levels on page 169

The system generates SNMP traps according to operating specifications defined in
supported MIBs.
IP Hosts
Traps are sent to IP hosts. The IP hosts are configured in a proprietary trap host table
maintained by the router (the server). Each entry in the table contains:
â– IP address of the trap destination
â– Community name (v1 or v2c) or username (v3) to send in the trap message
