Managing the XSR
Setting Port Configuration Mode
The configuration mode setting for ports on the XSR is as follows:
 Single-channel ports are configured in Interface configuration mode.
 Multi-channel ports are configured in Controller configuration mode.
A physical layer data stream is identified by channel using the
controller command, and this channel group is then configured
using the
interface command.
Setting Interface Type and Numbering
Interface types and numbers are set as follows:
 Physical-type interface and port numbers are similar. Interface types
are Serial BRI and PRI (T1/E1), or FastEthernet/GigabitEthernet.
 Virtual Interfaces:
– Dial - Range: 0 to 255, Interface type: Dialer.
– VPN - Range: 0 to 255, Interface type: VPN tunnel/Dialer.
– Multilink - Range: 1 to 32767, Interface type: VPN tunnel.
– Frame Relay DLCI - Range: 16 to 1007, Interface type: Serial/FR.
– Sub-interface: Each sub-interface correlates with a physical
interface, starting at 0. The sub-interface number is Port
number.sub-interface number for single channel serial, port
number.channelgroupnumber.subinterface number for multi-channel.
Configuration Examples
The following examples display minimal interface configuration:
 FastEthernet Example
interface fastethernet 1 + Begins configuring interface/port 1
no shutdown + Enables the interface
 T1 Example
controller t1 1/0 + Begins configuring controller on NIM card 1, port 0
channel-group 3 timeslots 1, 3-6, 12
+
Maps timeslots 1, 3, 4, 5, 6, and 12 to channel group 3
no shutdown + Enables the interface
!
interface serial 1/0:3 + Configures channel group 3 defined above
encapsulation ppp + Sets interface encapsulation type to PPP
no shutdown + Enables the interface
