ID |
The LCR group name |
MC-Ctl State |
Specifies the multi-chassis state |
Work MDA |
Specifies the physical MDA that is acting as the working MDA for this LCR group |
Prot MDA |
Specifies the physical MDA that is acting as the protection MDA for this LCR group |
Active MDA |
Specifies the active MDA |
Request Byte |

Label |
Description |
|---|---|
LCR Group |
Specifies an LCR group |
Description |
A description of the LCR group |
Group ID |
The LCR group identifier |
Active MDA |
Displays the active MDA |
Working MDA |
Displays the physical MDA that is acting as the working MDA for this LCR group |
Protection MDA |
Displays the physical MDA that is acting as the protection MDA for this LCR group |
Revertive-mode |
The revertive mode of the LCR group: non-revertive — traffic remains on the protection MDA until another switch request is received revertive — when the condition that caused a switch to the protection MDA has been cleared, the traffic is switched back to the working MDA |
Revert-time (min) |
The configured time, in minutes, to wait after the working MDA has become functional again before making the working MDA active again. If the revertive mode is non-revertive, then this field is empty. |
Request byte |
Specifies the value of the request byte received or transmitted on the protection MDA |
Multi-Chassis LCR |
Indicates whether MC-LCR is configured |
Neighbor |
Displays the neighbor IP address. A 0.0.0.0 address indicates that the LCR group is an SC-LCR. |
Control link state |
Displays the current control link status |
Advertise Interval |
Displays the advertise interval |
Hold time |
Displays the hold time |
LCR Working MDA |
Specifies the working MDA |
Admin State |
Specifies whether the working MDA is administratively up or down |
Operational State |
Specifies the operational state of the working MDA |
Current LCR Status |
Specifies the current status of the LCR |
No. of Switchovers |
The number of switchovers that have occurred on this MDA |
Last Switchover |
Displays the timestamp of the last switchover |
Switchover Seconds |
Displays the cumulative Protection Switching Duration (PSD) time in seconds For a working MDA, this is the cumulative number of seconds that service was carried on the protection MDA |
Last Switch Cmd |
Displays the last switch command that was performed on the working MDA |
LCR Protection MDA |
Specifies the protection MDA |
Admin State |
Specifies whether the protection MDA is administratively up or down |
Operational State |
Specifies the operational state of the protection MDA |
Current LCR Status |
Specifies the current status of the LCR |
No. of Switchovers |
The number of switchovers that have occurred on this MDA |
Last Switchover |
Displays the timestamp of the last switchover |
Switchover Seconds |
Displays the cumulative Protection Switching Duration (PSD) time in seconds For the protection MDA, this is the cumulative number of seconds that the protection MDA has been used to carry any working MDA traffic. This information is only valid if revertive switching is enabled. |
Last Switch Cmd |
Displays the last switch command that was performed on the protection MDA |
