Changing the Trap Port for Multiple Network Management Applications
If you are running more than one network management application on your Site
Manager workstation, you must configure Site Manager to receive trap messages
from the SNMP agent on a port other than the default port, 162. This is necessary
for the following reasons:
• The agent can only send trap messages to one network management
application at a time.
• Only one application can map to a UDP port at a time.
By default, the network management application on your workstation is
assigned to User Datagram Protocol (UDP) port 162. This port is dedicated to
receiving SNMP trap messages from the SNMP agent.
Site Manager is the preferred network management application for receiving
trap messages. To avoid any problems when running another network
management application, Bay Networks recommends that you configure Site
Manager to map to an alternative UDP port. This allows you to send trap
messages to Site Manager directly.
To reconfigure the trap port:
1. In the Configuration Manager window, choose Protocols > IP > SNMP >
Communities.
The SNMP Community List window that opens (refer to Figure
7-2).
2. Choose Community > Managers.
The SNMP Manager List window opens (refer to Figure
7-3).
3. Choose Manager > Edit Manager.
The Trap Port and Trap Types window opens (refer to Figure
7-5).
4. Type a new port number for the Trap Port parameter, then click on OK.
You can enter any port number on your Site Manager workstation, as long as
another application is not using that port.
You return to the Configuration Manager window.
5. Choose File > Save to save this configuration file.
Refer to Chapter 3 for instructions on saving configuration files.
