Configuring Jumbo Frames
To enable and configure the hold-off timer, perform the following procedure, beginning in global
configuration mode:
Configuring Jumbo Frames
You can configure the interface to support jumbo frames. The jumbo setting specifies that the station
support a maximum transfer unit (MTU) of up to 9100 bytes.
Caution For jumbo frame support, you must configure all the stations on the ring to support jumbo frames.
Command Purpose
Step 1 Router(config)# interface rpr-ieee 0 Activates interface configuration mode to
configure the RPR-IEEE interface.
Step 2 Router(config-if)# rpr-ieee protection
sonet holdoff-timer time [east | west]
Specifies the delay before a protection response is
sent. Values range from 0 to 20, in units of 10
milliseconds. The default is 0.
(Optional) You can also specify the east or west
ringlet.
Caution When using SW-LCAS on the
RPR-IEEE, the addition or deletion of a
SW-LCAS member circuit causes a
traffic hit with a maximum of 50 msec.
The holdoff timer requires a value
greater than 5 (50 msec) or the
SW-LCAS addition or deletion triggers
a protection response
Step 3 Router(config)# no shut Enables the RPR-IEEE interface and changes the
mode from the default passthrough.
Step 4 Router(config)# end Returns to privileged EXEC mode.
Step 5 Router# copy running-config startup-config (Optional) Saves configuration changes to the
TCC2/TCC2P flash database.
