When broadcast traps are enabled, the switch transmits traps to all NMS stations in the default 
group. If you enable this parameter, unicast traps (see option 6 below) will automatically be 
disabled. The default for broadcast traps is 

. To enable broadcast traps, enter the 

following command:

The following prompt displays:

Enter the 

UDP

 destination port for the traps. 

UDP

 port 162 is the default port and is commonly 

used for traps; however, the destination port can be re-defined to accommodate a network 
management station using a nonstandard port.

♦ Note ♦

The destination port configured here must corre-
spond to the 

UDP

 destination port configured at the 

receiving network management station(s).

When unicast traps are enabled, the switch transmits traps only to the 

IP

 address(es) defined 

in the 

 list below this field. 

♦ Note ♦

If both broadcast and unicast traps are disabled, then 
the switch does not transmit any traps. 

If you enable this parameter, broadcast traps (see option 5 above) will automatically be 
disabled. The default for unicast traps is disabled. To enable unicast traps, enter the follow-
ing command:

a. To define a new network management station, enter 8, followed by an equal sign (

), and 

the 

IP

 address of the network management station to receive traps. You can define a maxi-

mum of ten network management stations. They must be numbered sequentially from 8 
through 17. If network management stations are already shown on the display for this 
menu, use the next highest number to add another station. The following is an example of 
how to define the first network management station:

The following prompt displays:

Each trap in the switch is assigned a mask that consists of “words”. The mask value 

indicates that all traps are enabled for words 0 and 1. If you want to accept 

this default (all traps enabled for words 0 and 1), press <

>. If you want to enable 

one or more specific traps for words 0 and 1, you must calculate their bit configurations 
and enter the new mask value at the prompt. Trap types and their bit positions are listed 
in the tables beginning on page 13-11.
