Configuring the LAN Ports
3-8 Software Configuration
Enter the following command to configure the XSR as an SNTP client:
XSR(config)#sntp-client server [primary | A.B.C.D.][alternate | A.B.C.D.]
Enter the following command to configure the XSR as an SNTP server:
XSR(config)#sntp-server enable
Remember to save your configuration after all edits.
Configuring the LAN Ports
1. Enter interface gigabitethernet <1 | 2 | 3> to acquire Interface mode and select one of the
GigabitEthernet ports.
2. Enter ip address <xxx.xxx.xxx.xxx> <yyy.yyy.yyy.yyy> where x is the IP address and y is the
subnet mask of this GigabitEthernet port.
3. Enter no shutdown to keep the interface enabled.
4. Enter show ip interface gigabitethernet <1 | 2 | 3> to verify LAN settings.
5. Enter copy running-config startup-config to save your settings.
Remember to save your configuration after all edits.
Configuring the WAN Ports
For ISDN PRI configuration, continue below; or see “BRI Configuration” on page 3-9, or “ADSL
Configuration” on page 3-11.
PRI Configuration
1. Enter controller <t1 | e1> <slot # | card # | port #> of the first installed T1/E1/ISDN-PRI NIM
to acquire Controller mode and set up the physical port.
2. Enter no shutdown to keep the interface enabled.
The above commands add either one channel-group 0 having 24 timeslots for the T1 controller
with default values for framing set to ESF, B8ZS line encoding, and line clock source, or one
channel-group 0 having 31 timeslots for the E1 controller including crc4 framing, hdb3 line
encoding, and line clock source defaults. For a non-default configuration, go to Step 3.
3. Enter clock source <line | internal | internal synchronization> to select where the XSR will
derive its timer for synchronized data transmission.
The line source derives from the network, internal derives from a chip on the XSR, and
internal synchronization derives from the first T1/E1/ISDN-PRI card by clock transfer.
4. Enter no channel-group <number> to delete the default group.
5. Enter channel-group <number> timeslot <number> <speed> <number> to create a channel
group.
