Chapter 2 Utilizing the Command Line Interface
Managing the XSR
Switched: When configuring a switched BRI connection, three serial
sub-interfaces are automatically created when you enter:
interface bri 2/1
isdn switch-type basic-ni1
The following sub-interfaces are added:
interface serial 2/1:0
interface serial 2/1:1
interface serial 2/1:2
These serial sub-interfaces are removed with the no isdn
switch-type
command as follows:
interface bri 2/1
no isdn switch-type +
This deletes serial ports 2/1:0, 2/1:1 and 2/1:2
Entering Commands that Control Tables
A number of CLI commands configure entries in tables such as arp and
access-list in the XSR. Two type of tables are configurable:
 Single-instance table: The ARP table, for example, in which one table
contains many rows and each row is a complete entry. Entries are not
displayed in the same order they are entered.
 Multiple-instance table: The Access-List table, for example, in which
there are multiple tables identified by number with each table
containing many rows and each row is a complete entry. Entries are
not displayed in the same order they are entered.
With few exceptions, you must be in Global mode before issuing table commands.
Adding Table Entries
Depending on the type of table configured, the parameter list can be optional
or required. For example the ARP table has three required parameters and
some optional values depending on the context. For example, using the
following command:
arp ip-address mac-address
you may type:
XSR(config)#arp 1.1.1.1 e45e.ffe5.ffee
