Command Purpose
Step 1
Switch# show ces status Displays information about the current CBR
interfaces.
Use this command to choose the ports to be
configured with CAS enabled.
Step 2
Switch# configure terminal
Switch(config)#
At the privileged EXEC mode prompt, enters
global configuration mode.
Step 3
Switch(config)# interface cbr card/subcard/port
Switch(config-if)#
Selects the source interface to be configured.
Step 4
Switch(config-if)# no shutdown Reenables the interface.
Step 5
Switch(config-if)# ces dsx1 signalmode
robbedbit
Configures the signal mode to robbedbit
(CES T1 only).
Step 6
Switch(config-if)# ces circuit circuit-id cas Enables channel-associated signalling.
Step 7
Switch(config-if)# exit
Switch(config)#
Returns to global configuration mode.
Step 8
Switch(config)# interface cbr card/subcard/port
Switch(config-if)#
Selects the destination interface to be configured.
Step 9
Switch(config-if)# shutdown Disables the interface.
Step 10
Switch(config-if)# ces dsx1 signalmode
robbedbit
Configures the signal mode to robbedbit
(CES T1 only).
Step 11
Switch(config-if)# ces circuit circuit-id cas Enables channel-associated signalling.
Step 12
Switch(config-if)# no shutdown Reenables the interface.
