Circuit emulation services-interworking functions (CES-IWF) and constant bit rate (CBR) traffic relate 
to a quality of service (QoS) classification defined by the ATM Forum for Class A (ATM adaptation layer 
1 [AAL1]) traffic in ATM networks. In general, Class A traffic pertains to voice and video transmissions, 
which have particular clocking requirements. For details, refer to 

The default software image for the ATM switch router contains the Private Network-Network Interface 
(PNNI) routing protocol. The PNNI protocol provides the route dissemination mechanism for complete 
plug-and-play capability. The following section, “

,” 

describes modifications that can be made to the default PNNI or Interim-Interswitch Signalling Protocol 
(IISP) routing configurations.

For routing protocol configuration information, refer to 

and 

Static route configuration allows ATM call setup requests to be forwarded on a specific interface if the 
addresses match a configured address prefix. To configure a static route, use the following command in 
global configuration mode:

An interface must be User-Network Interface (UNI) or Interim Interswitch Signalling Protocol (IISP) to 
be configured with static route. Static routes configured as PNNI interfaces default as down.

The following example shows how to use the atm route command to configure the 13-byte peer group 
prefix = 47.0091.8100.567.0000.0ca7.ce01 at interface ATM 3/0/0:

Switch(config)# atm route 47.0091.8100.567.0000.0ca7.ce01 atm 3/0/0

Switch(config)# 

atm route addr-prefx atm card/subcard/port

Specifies a static route to a reachable address 
prefix.
