Configuring Signalling Features
Disabling Signalling on an Interface
Disabling Signalling on an Interface
If you disable signalling on a Private Network-Network Interface (PNNI) interface, PNNI routing is also 
disabled and Integrated Local Management Interface (ILMI) is automatically restarted whenever 
signalling is enabled or disabled.
To disable signalling on an interface, perform the following steps, beginning in global configuration 
mode:
Example
The following example shows how to shut down signalling on ATM interface 0/1/2:
Switch(config)# interface atm 0/1/2
Switch(config-if)# no atm signalling enable
Switch(config-if)#
%ATM-5-ATMSOFTSTART: Restarting ATM signalling and ILMI on ATM0/1/2.
Multipoint-to-Point Funnel Signalling
Multipoint-to-point funnel signalling (funneling) merges multiple incoming switched virtual channels 
(SVCs) into a single outgoing SVC. This feature supports the Microsoft Corporation Proprietary Funnel 
Join (or Flow Merge) Protocol.
No configuration is necessary to enable this feature. For a complete description, refer to the Guide to 
ATM Technology
.
Displaying Multipoint-to-Point Funnel Connections
To display multipoint-to-point funnel connections, use the following EXEC commands:
Command
Purpose
Step 1
Switch(config)# interface atm card/subcard/port
Switch(config-if)#

Step 2
Switch(config-if)# no atm signalling enable
Disables signalling on the interface.
Command
Purpose
