4For host inet, type the IP address of the remote host.

5If the remote host is on a different network, type the IP address of the gateway node at the gateway inet prompt.

6For user, type the FTP userid of the remote host.

7For ftp password, type the FTP password of the remote host.

8Reboot the Passport 8250 device to save the boot parameters. reboot

Note: After restarting the Passport 8250, you can log into the CLI only after ****BOOT COMPLETE, SYSTEM IS READY**** is displayed.

Configuring the clocking scheme

To configure the clocking scheme for the Passport 8250 device, select the source for the reference clock, and, if applicable, select the switching option using the clockconfig command.

The switching methods are the following:

•Internal. The clocking scheme is derived from the Passport 8250 device.

•External. The clocking scheme is derived from the ATM network off the ATM uplink port or a T1/E1 port on the Passport 8250. Select one of the following switching options:

— Fixed. The clocking scheme is fixed permanently to the primary port. If there is a problem with the primary port, you need to change to the secondary port using the clockconfig command.

—Automatic switching. The clocking scheme is temporarily fixed to the primary port. The Passport 8250 automatically switches from the primary port to the secondary port and, if needed, switches from the secondary port to internal.

Note: We recommend that you select the device with the lower stratum clock as the clock source. The Passport 8250 has a stratum 4 clock.

The syntax of the clockconfig command is:

clockconfig [set]
