DGS-3130 Layer 3 Stackable Managed Switch CLI Reference Guide Switch# configure terminal Switch(config)# ethernet ring g8032 ring2 Switch(config-erps-ring)# exit Switch(config)# ethernet ring g8032 ring1 Switch(config-erps-ring)# sub-ring ring2 Switch(config-erps-ring)# exit Switch(config)# ethernet ring g8032 ring2 Switch(config-erps-ring)# port1 none Switch(config-erps-ring)# 33-14 revertive This command is used to restore to the working transport entity, in the case of the clearing of a defect. Use the no form of this command to continue to use the RPL, if it is not failed, after the Switch link defect condition has cleared. revertive no revertive Parameters None. Default By default, this option is enabled. Command Mode G.8032 Profile Configuration Mode. Command Default Level Level: 12. Usage Guideline In the case of clearing a defect, the traffic channel reverts after the expiry of the WTR timer, which is used to avoid toggling protection states in the case of intermittent defects. In non-revertive operation, the traffic channel continues to use the RPL, if it is not failed, after a switch link defect condition has cleared. Since in Ethernet ring protection the working transport entity resources may be more optimized, in some cases it is 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 to the working transport entities immediately. In this case, a second traffic interruption is avoided by not reverting protection switching. Example This example shows how to configure rings in the ring profile "campus" to operate in the non-revertive mode. Switch# configure terminal Switch(config)# ethernet ring g8032 profile campus Switch(config-erps-ring-profile)# no revertive Switch(config-erps-ring-profile)# 363
