This command displays failover pool statistics.
The following output is an example of failover pool stats information
Table 138 describes failover pool statistics output fields.
Field | Description |
Failover Admin State | Identifies the failover state of the DHCP server instance inService — The failover admin state is in service outOfService — The failover admin state is out of service |
Failover Oper State | The operational state of a DHCP server instance |
Failover Persist Key | The maximum amount of time that one server can extend a lease for a client's binding beyond the time known by the partner server |
Administrative MCLT | The administrative Maximum Client Lead Time (MCLT) |
Operational MCLT | Indicates the operational MCLT |
Startup Wait Time | The startup wait time. The startup wait time is the time that one IP address pool attempts to contact the partner IP address pool. During this time, the IP address pool is unresponsive to DHCP client requests. |
Partner Down Delay | The minimum safe-time after the beginning of COMMUNICATIONS-INTERRUPTED state. After the expiry of this time, the server enters the PARTNER-DOWN state. |
Ignore McLT | The ignore McLT status. If, after the transition COMMUNICATIONS-INTERRUPTED-to-PARTNER-DOWN state, the DHCP server instance ignores the safety period with a duration of Maximum Client Lead Time; a ‘true’ value has the effect that the DHCP server starts offering IP addresses from the partner's scope immediately after this transition, without waiting for existing leases allocated by the partner and not known by this system to time out. A ‘true’ value increases the risk that duplicate addresses are offered; if the transition to PARTNER-DOWN state is likely to be caused by a failure of the partner system rather than a communications problem, this risk is reduced. |

This command forces a DHCP server to transition from the COMMINICATIONS-INTERRUPTED state to the PARTNER-DOWN state.
It is important to note that this command should only be used if the remote DHCP server is out of service, else duplicate address allocations could occur.
In case of a communication failure between two redundant DHCP servers, the DHCP server transitions to the COMMUNICATIONS-INTERRUPTED state. In this state, the DHCP server allocates IP addresses for new leases from the local and address-driven address-ranges only. This prevents duplicate address allocations.
If during the partner-down-delay time, the communication with the remote DHCP server is not restored, then the DHCP server transitions to the PARTNER-DOWN state. In this state, the DHCP server also allocates IP addresses for new leases from the remote ranges. A DHCP server should only reach this state when the remote DHCP server is out of service, else IP address conflicts can occur.

This command displays NAT MAP fragmentation information.
The following is sample output for this command, and Table 158 describes the fields.
Label | Description |
Rx Resolved Packets | Specifies fragments that were resolved and never buffered. This includes:
|
Rx Unresolved Packets | Specifies the number of packets that were queued in the system since the last clear command was invoked. For example, out-of-order fragments without a matching flow record (missing the first fragment). These packets can be eventually resolved and forwarded, or discarded (for example, as a result of timeout). |
Tx Frags | Specifies the fragments that were transmitted (Rx Resolved and Rx Unresolved that were eventually resolved) out of the fragmentation logic within the VSR. There is no guarantee that these fragments will be transmitted out of the system as they may be dropped on egress due to congestion or restrictions imposed by the configured filter. |
Dropped Frags | Specifies the dropped fragments due to some fragmentation issue (timeout, buffer full). |
Created Flows | A cumulative counter that represents the total number of flow records since the last clear command was invoked. It only counts the first fragment and roughly represents the amount of fragmented packets that were processed by the system since the last clear command. The counter does not provide any indication about the number of flows (packets whose fragments were transmitted fully) that were actually transmitted. |
Flow Collisions | Represents the number of overlapping first fragments. For example, when a flow record already exists and another first fragment for this flow is received. |
Exceeded Max Flows | Specifies the number of occurrences when the number of flows in the system exceeded its maximum supported value. |
Exceeded Max Timeouts | Specifies the number of fragments that have timed out (since the last clear command):
|
Exceeded Max Buffers | Specifies the number of occurrences when the number of buffers in the system exceeded its maximum supported value. |
Exceeded Max Timeouts | Specifies the number of fragments that have timed out (since the last clear command):
|
Exceeded Max Buffers | Specifies the number of occurrences when the number of buffers in the system exceeded its maximum supported value. |
Exceeded Max Buffers Per Flow | Specifies the number of occurrences when a fragment count per flow has exceeded its limit. |
In-Use Flows | An approximation of the number of flow records that are currently in use. The counter provides an estimate, expressed in percent, of the number of fragmented packets that were being processed at the time the counter was invoked. |
Max Flows | Specifies the amount of time in seconds that the system will remain in a hold down state before being used again. |
In-Use Buffers | Represents the amount of buffered fragments, expressed in percent of the maximum buffer space, that can be used for fragmentation. |
Max Buffers | A non-cumulative counter that represents the maximum number of buffers allocated since the last clear command. The counter captures the highest value of the buffers-in-use counter since the last clear command. The counter shows the percentage of the total buffer space that can be used by fragmentation. |
