• BRI-Dialer (IDSN) Example
interface dialer 0 + Configures dialer interface 0
ip address 2.2.2.2 255.255.255.0 + Sets IP address/subnet on port
encapsulation + Interface/Sub-interface Behavior
XSR interfaces and sub-interfaces, channels and channel-groups are added and deleted differently
depending on the particular interface. Interface characteristics are as follows:
• T1/E1 Controller - Creating a channel group adds a serial interface. For example, when you
issue the command
controller t1 1/0 , the XSR automatically creates channel group 0 with
all available timeslots assigned to it. You can verify this by checking the running configuration
where the following entry is displayed:
interface serial 1/0:0
– You can create other serial objects by creating more channel groups. For example, by
entering the following commands:
channel-group 0 timeslots 1-10 speed 64
channel-group 1 timeslots 11-20 speed 64
– the following interfaces are added:
interface serial 1/0:0
interface serial 1/0:1
– You can delete those controller interfaces only by removing the channel groups which
automatically created them by entering:
no channel-group 0 + This automatically deletes Serial port 1/0:0
no channel-group 1 + This automatically deletes Serial port 1/0:1
– To delete controller ports and all associated interfaces, you must remove the entire
controller:
no controller t1 1/0
• PRI NIM - When configuring a PRI interface, a pri group is created as follows:
controller t1 1/0
pri-group
– Creating a PRI group adds a serial interface internally, but it is not visible nor accessible to
the user:
interface serial 1/0:0 is not displayed anywhere. But, the system
resources associated with it remain in use until the pri group is deleted as follows:
no pri-group
• BRI NIM - When configuring a BRI interface, sub-interface addition/removal differs if you are
configuring a leased line or switched connection.
– Leased line: When configuring a leased line connection, serial sub-interfaces are created
and are visible to the user:
interface bri 2/1
leased-line 64
+ This adds serial port 2/1:1
leased-line 64 + This adds serial port 2/1:2
– These serial interfaces are removed by deleting the entire controller. For example:
interface bri 2/2
no controller t1 2
