Conﬁguring the clocking scheme

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

The switching methods are the following:

• Internal. The clocking scheme is derivedfrom the Passport 8250 device.

• External. The clocking schemeis derivedfromthe ATM network off the ATM uplink port or aT1/E1 port on the Passport 8250. Select oneof the following switching options:

241-5101-200 R2.2

— Fixed. The clocking scheme is ﬁxed permanently to the primary

port. If there is a problem with theprimaryport,you need to change to the secondary port using the clockconﬁg command.

— Automatic switching. The clocking scheme is temporarily ﬁxed to

theprimaryport.The Passport8250automaticallyswitches from the primary port to the secondary port and, if needed,switchesfromthe 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:
