Cisco Systems OL-5512-01 Configuring ATM and Frame Relay Circuits, Committed Information Rate CIR

Chapter 6 Adding Cisco IOS Routers to Cisco WAPMS

Configuring ATM and Frame Relay Circuits

Configuring ATM and Frame Relay Circuits

You configure Frame Relay or ATM virtual circuits for the router in the Circuits pane of the Network Configuration window (see Figure 6-1 on page 6-2). The Circuits box shows the circuit number, name, AAL type (for ATM), far site, far access line, and far circuit number.

Configuring circuits involves:

•adding the circuit end points to the access lines

•customizing the circuit end points (optional)

•configuring the circuit connections between the circuit end points.

To view read-only circuit settings, click Properties. For Frame Relay circuit information, see Figure 6-5and Table 6-2. For ATM circuit information, see Figure 6-6and Table 6-3.

Table 6-2 Frame Relay DLCI Settings for Cisco Routers

Option	Description
Committed Information Rate (CIR)	Maximum data rate at which the router/FRAD can send data
	without risk of dropped packets. This setting is applied to all
	DLCIs discovered by the ASE.
Excess Burst Allowed (Be)	Maximum allowable excess burst rate beyond the CIR; can be
	determined by router or port. Calculated as port speed - CIR.
	This setting is applied to all DLCIs discovered by the ASE.
