Description

(M320, M40e, M120, T320, T640, and T1600 routers and PTX Packet Transport Routers only) Change the external clock source used for chassis synchronization.

Options

external-a
—

(Routing matrix only) Change the synchronization source to external source A.

external-b
—

(Routing matrix only) Change the synchronization source to external source B.

bits-a
—

(PTX Series only) Change the synchronization source to the BITS external source A.

bits-b
—

(PTX Series only) Change the synchronization source to the BITS external source B.

fpc-slot-number
—

(PTX Series only) Change the synchronization source to an FPC in the slot specified. For the PTX5000 Packet Transport Router, replace slot-number with a value from 0 through7.

gps-0-10mhz
—

(PTX Series only) Change the synchronization source to the 10 MHz GPS source on CCG port 0.

gps-0-5mhz
—

(PTX Series only) Change the synchronization source to the 5 MHz GPS source on CCG port 0.

gps-1-10mhz
