Configuring and Managing
Routers with Site Manager
Version 15.3.0.0
The following section is an amendment to Chapter 7, “Monitoring Trap and Event
Messages” in Configuring and Managing Routers with Site Manager.
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, Nortel 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.
