Description
(M320, M40e, M120, T320, T640, and T1600 routers and PTX Packet Transport Switches 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 Switch, 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 | — | (PTX Series only) Change the synchronization source to the 10 MHz GPS source on CCG port 1. |
gps-1-5mhz | — | (PTX Series only) Change the synchronization source to the 5 Hz GPS source on CCG port 1. |
