Configuring the LAN Ports

XSR(config)#sntp-server enable

Remember to save your configuration after all edits.

1.Enter interface gigabitethernet <1 2 3> to acquire Interface mode and select the first, second or third GigabitEthernet port.

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-defaultconfiguration, 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.

This command allows multiple logical WAN interfaces to be created on a single channelized T1/E1/ISDN-PRI port, ranging from 0 - 23 for T1 lines, and 0 - 31 for E1 lines. Also, from 1 - 24 T1 and 1 - 31 E1 timeslots can be set. Channel speed options are 56 (T1) or 64 (E1) kbps.

Note: Channel group and timeslot number ranges are different. Be sure to match them correctly and within the range. Also, when adding a second T1 or E1, be sure to begin channel numbering again at 0.

6.Enter framing <sf esf crc4 no-crc4> to set the framing type.
