Alternate SVC Diagnostics
This section describes an alternate method you can use to troubleshoot SVC signalling, using the
atm signalling diagnostics command.
Use the following commands starting at the privileged EXEC prompt to check SVC signalling:
Follow these steps to check SVC signalling:
Step 1 Use the atm signalling diagnostics enable command to enable ATM signaling diagnostics.
Switch# configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
Switch(config)# atm signalling diagnostics enable
Step 2 Use the atm signalling diagnostics filter-index-number command to configure an ATM signaling
diagnostics filter number.
Switch(config)# atm signalling diagnostics 1
Command Purpose
Step 1
Switch# configure terminal
Switch (config)#
Enters configuration mode from the
terminal.
Step 2
Switch (config)# atm signalling diagnostics
enable
Switch (config-atmsig-diag)#
Enables ATM signaling diagnostics.
Step 3
Switch (config-atmsig-diag)# atm signalling
diagnostics filter-index-number
Starts ATM signaling diagnostics, using
an index number from 1 to 50, and
changes the prompt to ATM signaling
diagnostics configuration mode.
Step 4
Switch (config-atmsig-diag)# incoming-port atm
card/subcard/port
Configures the incoming port to filter.
Step 5
Switch (config-atmsig-diag)#
called-nsap-address NSAP-address
Sets the full called side NSAP address to
filter.
Step 6
Switch (config-atmsig-diag)# status active Activates the filter.
Step 7
Switch (config-atmsig-diag)# end
Switch#
Exits signaling diagnostic configuration
mode.
Step 8
Switch# show atm signalling diagnostics filter
filter-index-number
Displays the configuration of the ATM
signaling diagnostics filter.
Step 9
Switch# show atm signalling diagnostic records
filter-index-number
Displays any captured records for this
signaling diagnostics filter.
Step 10
Switch# configure terminal
Switch (config)#
At the privileged EXEC prompt, enters
configuration mode from the terminal.
Step 11
Switch (config)# no atm signalling diagnostics
enable
Disables ATM signaling diagnostics.
