revertive
This command is used to revert back to the working transport entity, for example, when the RPL was blocked.
Use the
no
form of this command to continue using the RPL, if it has not failed and if the ‘switch link defect’
condition was cleared.
revertive
no revertive
Parameters
None.
Default
By default, this option is
revertive
.
Command Mode
G.8032 Profile Configuration Mode.
Command Default Level
Level: 15.
Usage Guideline
When a defect was cleared, the traffic channel will revert after the WTR timer has expired, which is used to
avoid toggling protection states caused by intermitted defects.
n the non-revertive operation, the traffic channel continues to use the RPL if it did not fail after a ‘switch link
defect’ condition was cleared. Since in Ethernet ring protection the working transport entity resources may be
more optimized and in some cases it is more desirable to revert to this working transport entity once all ring
links are available. This is performed at the expense of an additional traffic interruption. In some cases there
may be no advantage to revert back to the working transport entity immediately and in some cases a second
traffic interruption is even avoided by not reverting protect switching.
Example
This example shows how to configure rings in the profile “campus” to operate in non-revertive mode.
Switch# configure terminal
Switch(config)# ethernet ring g8032 profile campus
Switch(config-g8032-ring-profile)# no revertive
Switch(config-g8032-ring-profile)#
11-12
rpl
This command is used to configure the node as the RPL owner, or assign the port as the RPL port.
Use the
no
form of this command to remove the settings.
rpl {port0 | port1} [owner]
