# Traps Receivers

Device>Configure>Traps

Each managed device sends its traps or error messages to a management station. For example, a trap is sent whenever a port or device is reset or an incorrect community string is detected by the switch or router.

The Traps window contains the following MIBs:

Traps Receivers Table

The Trap Receiver table displays the IP addresses and the Read community strings of the destination network management stations. The Trap Receiver table can contain a maximum of ten entries, even though the dialog box displays more than ten rows.

Click Create to create a new row in the Trap Receiver table, then enter the IP Address and Community String and click Apply, or click Delete to remove the currently selected row.

Note: The rows in the Trap Receivers Table are numbered beginning with 0, so if you try to delete the second row, a message appears asking if you want to delete row 1.

Click Cancel to close the dialog box without making any changes. Click Print to print the contents of the dialog box.

Command Line Alternative: You can set trap configurations via the command line CLI/SNMP
To set an snmp trap, use:

set snmp trap <enable | disable> [vtp | ippermit | vmps | config | entity | stpx]
set snmp trap <rcvr_address> <rcvr_community>
show snmp
