Table 14: Command output
Field | Description |
---|---|
Restart status | Restart state of the device:
|
Restart phase | Restart phase:
|
Restart Interval | The maximum adjacency hold time (in seconds). If the restarting device fails to complete restarting before this timer expires, the peer ISIS-SPB process removes the adjacency with the restarting ISIS-SPB. This timer is configurable with the graceful-restart t2 command. |
SA bit | Support for setting the SA bit in the Restart TLV sent to the neighbor:
|
Total number of interfaces | Number of SPBM-enabled interfaces. |
Number of waiting LSPs | Number of LSPs that are waiting to be synchronized with the GR helper for completing LSDB synchronization. |
T2 remaining time | The remaining time (in seconds) of the T2 timer. If the restarting device fails to complete restarting before this timer expires, the neighbor removes the adjacency with the restarting device. |
T1 remaining time | Remaining time (in seconds) of the T1 timer on the interface. The T1 timer sets the interval for the restarting device to retransmit hello messages with the RR bit set (restart request messages). The T1 timer is not user configurable. The restarting device retransmits a restart request message to the neighbor if it does not receive an acknowledgment for a restart request (hello message with the RA bit set) before the T1 timer expires. |
RA received | Whether the interface received an ISIS-SPB hello with the RA flag from the neighbor device. |
CSNP received | Whether the interface received a CSNP from the neighbor device. |
T1 expirations | Number of T1 timer expirations on the interface. When this counter reaches 10, the restarting device stops retransmitting hello messages with the RR bit set. |
