Description |
|---|---|
Interface |
Specifies the APS interface name (the APS group port) |
Admin State |
Specifies whether the APS interface is administratively up or down |
Oper State |
Specifies whether the APS interface is operationally up or down |
MC-Ctl state |
Specifies the multi-chassis state |
Work Circuit |
Specifies the physical port that is acting as the working circuit for this APS group |
Prot Circuit |
Specifies the physical port that is acting as the protection circuit for this APS group |
Active Circuit |
Specifies the active circuit |
Tx/Rx K1 Byte |
Displays the value of the SONET/SDH K1 byte received or transmitted on the protection circuit |
APS Group |
Displays the APS group name |
Description |
Displays the APS group description |
Group ID |
Displays the APS group ID number |
Active Circuit |
Specifies the physical port that is acting as the active circuit for this APS group |
Admin Status |
Specifies whether the APS circuit is administratively up or down |
Oper Status |
Specifies whether the APS circuit is operationally up or down |
Working Circuit |
Displays the physical port that is acting as the working circuit for this APS group |
Protection Circuit |
Displays the physical port that is acting as the protection circuit for this APS group |
Switching-mode |
Displays the switching mode of the APS group |
Switching-arch |
Displays the architecture of the APS group |
Revertive-mode |
Displays the revertive mode of the APS group: non-revertive — traffic remains on the protection line until another switch request is received revertive — when the condition that caused a switch to the protection line has been cleared, the signal is switched back to the working line |
Revert-time |
Displays the configured time, in minutes, to wait after the working circuit has become functional again before making the working circuit active again. If the revertive mode is non-revertive, then this field is empty. |
Rx K1/K2 byte |
Displays the value of the SONET/SDH K1/K2 byte received on the interface |
Tx K1/K2 byte |
Displays the value of the SONET/SDH K1/K2 byte transmitted on the interface |
Current APS Status |
Displays the current APS status |
Multi-Chassis APS |
Indicates whether MC-APS is configured |
Neighbor |
Displays the neighbor IP address. All zeros indicates the APS group is an SC-APS. |
Control link state |
Displays the current control link status |
Mode mismatch Cnt |
Indicates the number of times a conflict occurs between the current local mode and the received K2 mode information |
Channel mismatch Cnt |
Indicates the number of mismatches between the transmitted K1 channel and the received K2 channel that have been detected |
PSB failure Cnt |
Displays a count of Protection Switch Byte (PSB) failure conditions. This condition occurs when either an inconsistent APS byte or an invalid code is detected. |
FEPL failure Cnt |
Displays a count of far-end protection-line (FEPL) failure conditions. This condition is declared based on receiving SF on the protection line in the K1 byte. |
No. of Switchovers |
Displays the number of times a switchover has occurred |
Last Switchover |
Displays the timestamp of the last switchover |
Switchover seconds |
Displays the cumulative Protection Switching Duration (PSD) time in seconds For a working channel, this is the cumulative number of seconds that service was carried on the protection line For the protection line, this is the cumulative number of seconds that the protection line has been used to carry any working channel traffic. This information is only valid if revertive switching is enabled. |
Signal Degrade Cnt |
Displays the number of times the signal was degraded |
Signal Failure Cnt |
Displays the number of times the signal failed |
Last Switch Cmd |
Reports the last switch command that was performed on a circuit |
Last Exercise Result |
Displays the result of the last exercise request on a circuit |
Advertise Interval |
Displays the advertise interval |
Hold time |
Displays the hold time |
