Utilizing the Command Line Interface

XSR User’s Guide 2-19

• 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

1 2 ... 50 51 52 53 54 55 56 57 58 59 60 ... 465 466
