The switching method options are automatic switching and manual
switching. For automatic switching, the Passport 8250 changes from the
primary port to the secondary port. For details on automatic switching, see
“Configuring the redundant ATM uplink port for automatic switching”
(page 55).
For manual switching, you use the urconfig command to change from the
primary port to the secondary port. For details on manual switching, see
“Configuring the redundant ATM uplink port for manual switching”
(page 57).
