limit. The default value should be satisfactory in most situations. An

example of a situation where it is bene®cial to change this value would be if the majority of the stations use 25±Mbps adapters. In this case, it may be desirable to limit the data rate on VCCs to 25 Mbps so that the lower speed stations are not overwhelmed with frames from the router. The units for this parameter are Mbps.

Valid Values:

25

100

155

Default Value:

25

Example:

ATM INTERFACE> set speed 25

max-calls

Sets the maximum number of switched virtual circuits (SVCs) that can exist on this ATM device. Every point-to-point and point-to-multipoint SVC uses system resources. This parameter helps limit the system resources reserved for signaling and switched connections. Increasing this parameter will allow more simultaneous SVCs. However, more system memory will be required to manage these connections.

Valid Values:

An integer in the range 64 - 10500

Default Value:

1024

Example:

ATM INTERFACE> set max-calls 500

max-callers

Sets the maximum number of entities on the router that use the ATM interface. Each LEC, Classical IP Client, and 1483 bridge interface quali®es as a user of the ATM interface. Increasing this parameter allows more users of the interface and uses more system memory.

Valid Values:

An integer in the range 64 ± 1024

Default Value:

209

Example:

ATM INTERFACE> set max-callers 25

max-con®g-selectors

Sets the maximum number of selectors under your speci®c control.

The selector is used to distinguish different users on the same end system. VCC setup requests are routed in the following hierarchical fashion: ATM switches route to the destination ATM switch using the Network Pre®x, the destination ATM switch routes to the destination end system using the ESI, and the end system noti®es the destination user based on the selector.
