ILMI Neighbor Discovery
On the BPX, if the BXM runs LMI/ILMI, the BCC must send Abit update to the card. These messages
are throttled. When this happens, the estimated time to reroute all 12K connections increases no more
than five percent.
Note
On the IGX, enabling the Sending Abit Notification using Configurable Timer feature can impact
performance if many connections end at Frame Relay cards. This is due to the restricted format of
interface between NPM and Frame Relay cards.
ILMI Neighbor Discovery
The ILMI Neighbor Discovery feature, available only with the BXM card, enables a network
management system such as Cisco WAN Manager or CiscoWorks 2000 to discover other attached ATM
devices such as Cisco ATM routers or switches. The ATM devices must also support ILMI Neighbor
Discovery.
Configuring the BPX for ILMI Neighbor Discovery
To enable ILMI Neighbor Discovery on the BXM card, use the following the procedure.
Step 1
Enter the cnfport command to set the BXM card parameters as listed in Table 19-4.
Step 2
