Using SNMP Traps with 
Third-Party Network
Management Platforms

Most third-party management platforms, such as HP OpenView, cannot automatically
write the trap destination (IP address of management system) to NJ200 Network Jack
during discovery. Although the switches support MIB-2, RMON, and SNMP agents,
they cannot be configured from 3Com Central Configuration Manager to communicate
with the network management platform (IP address of network management system).
Instead, the trap destination must be configured through a standard MIB browser. 

The following example helps illustrate how to write the trap destination to an NJ200
Network Jack Switch using a standard MIB-2 browser. In this example the receiving
device uses IP address 

:

IMPORTANT!: Please note that this procedure varies for different network management platforms. To
properly configure the trap destination for your particular network management platform, please consult
the software documentation for specific instructions.

1. Open the “

” command line. Most often, this will can be found under

.

2. In dot notation, 

represents 

. It may be

indexed with “

” and in that case is 

.

3. Create a row by setting 

value to 5.

4. Configure the 

(IP address of network management system) by 

setting # 

to 

, where

1.3.6.1.2.1.16.19.13.1.4.1 represents the default address indexed with “1”.

5. The first four bytes of the 

, “

”, should be the

IP address of the network management system, or trap receiver. 

Note: Insert a space, not a dot “

”, between the first four bytes. 

6. The last two bytes indicate which UDP port is used to send out traps. 

Do not use any number other than 162 (0xA2) for the last byte. NJ200 Network Jacks can only trap

SNMP information through UDP port 162 (0xA2).

7. Enable the trap destination by setting 1 to 

object, which in this case

is 

.

8. The NJ200 Network Jack is ready to send traps to the network management system

with the IP address 192.168.1.1.

9. Repeat these steps if additional trap destinations are needed. NJ200 Network Jack

can support up to four different trap destinations.
