Configuring Forced or Manual Switching
Purpose
Activates interface configuration mode to
configure the RPR-IEEE interface.
Enables jumbo frame capability on the RPR-IEEE
interface:
jumbo—Enables handling of frames in excess of
the standard size, up to a maximum size of 9100
bytes. A jumbo-enabled station changes the
interface MTU to 9100 bytes if all stations in the
ring are jumbo enabled. A message is generated to
indicate that the ring supports jumbo frames when
all stations are configured for this preference.
The default is to not support jumbo frames.
Enables the RPR-IEEE interface and changes the
mode from the default passthrough.
Returns to privileged EXEC mode.
(Optional) Saves configuration changes to the
TCC2/TCC2P flash database.
