Check Cisco devices
It is strongly recommended that firmware/software in your Cisco devices be IOS
version 12 or higher. If you want ATM or Frame Relay support, IOS 12 is
mandatory in your Cisco devices.
(Optional) Enable UDP port forwarding on routers
If you want to have your Peregrine appliance communicate with listener agents
across subnets, you will need to enable routing for the UDP packets. If you have
routers separating the broadcast domains in your network, you should
configure them to pass along listener broadcast traffic on port 1738, as well as
on the ports you have configured on your Peregrine appliance.
Note: Port 1738 is the default, but you can add other listener ports in
Administration > System Preferences > Listener communication.
By configuring the Peregrine appliance and your routers to listen for UDP
broadcasts on the same ports, Network Discovery will find new workstations
much faster.
For Cisco routers, a procedure is provided below. For any other manufacturer,
Peregrine recommends checking the router documentation to find a way to
forward UDP traffic between subnets.
To configure your Cisco IOS router
1 Access the EXEC privilege level on the configuration interface.
