Configuring SNMP Parameters and Traps
Page 13-4
6) Broadcast Traps
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
disabled
. To enable broadcast traps, enter the
following command:
5=enabled
The following prompt displays:
UDP destination port (162):
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).
7) Unicast Traps
When unicast traps are enabled, the switch transmits traps only to the
IP
address(es) defined
in the
snmpc
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:
6=enabled
Configuring a New Network Management Station
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:
8=123.12.1.1
The following prompt displays:
Enter trap mask words 0:1 (ffffffff:ffffffff):
Each trap in the switch is assigned a mask that consists of “words”. The mask value
ffffffff:ffffffff
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 <
Enter
>. 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.
