Entering the Physical Addresses of Devices to be Polled
You must designate the physical address of at least one intelligent Enterasys or
Cabletron device on your network to poll; the maximum number of addresses per
circuit is eight. These addresses define the destination nodes your Enterasys
management application will look for to determine the status of the active link.
The IRM2 will simultaneously poll all addresses on each circuit’s list; if it cannot
establish a link with any address on the list after the designated number of retries,
the IRM2 assumes the circuit is down and switches traffic to a designated backup
port.
To designate the polling addresses for a circuit:
1. With the selected circuit still displayed in the Current Circuit box, click on Add;
the Add Poll Address window,
Figure 7-4 , will appear.

2. Enter the physical address of the device you want polled.
3. Click to add the address to the list. If you have entered an address
that is not in the correct XX-XX-XX-XX-XX-XX hexadecimal format, an error
message will appear, and no address will be added to the list.
