Default severity

warning

Message format string

Server "$tmnxDhcpSvrNotifServerName$" could not allocate IP address to client (mac= $tmnxDhcpSvrNotifMsgHwAddress$). Reason: $tmnxDhcpSvrNotifString$

Cause

The tmnxDhcpsAddrAllocationFailure notification is generated when a DHCP server instance could not allocate an address for a client. The reason could be that the DHCP server instance could not find a free address, or it could be a configuration issue.

Effect

The client does not get an IP address lease this time. The client will have to try again if it needs a lease from this system.

Recovery

The recovery action, if any, will depend on the reason.

Cause

The tmnxDhcpsFoLeaseUpdateFailed notification is generated when a Binding Database Update (BNDUPD) packet received from the failover peer, cannot be processed successfully. The failure reason can be one of the following: foShutdown : the failover state of this DHCP Server instance is 'shutdown'; expired : the lease received from the peer has expired; maxReached : the maximum number of leases is already reached; subnetNotFound : no valid subnet for this lease could be found; rangeNotFound : no valid include range for this lease could be found.

Effect

If this DHCP server instance would have to perform a failover switch, it may lease addresses that were already given in lease by the failover peer. The effect is the same regardless of the failure reason.

Recovery

The required recovery action depends on the failure reason: foShutdown : put the DHCP server instance in state 'inService'; put the DHCP server instance failover facility in state 'inService'; expired : ensure the system clocks of this system and its failover peer are synchronized; maxReached : no recovery is possible; subnetNotFound : configure a valid subnet for this lease; rangeNotFound : configure a valid include range for this lease.

Default severity

warning

Message format string

DHCP server $tmnxDhcpServerCfgServerName$ changed failover state: $tmnxDhcpsFoState$.

Cause

The failover state of the DHCP server instance changed.

Effect

The effect depends on the new failover state: init | failover is not operational; the DHCP server startUp | instance is not operational; shutdown : failover is not operational; the DHCP server instance is operational in standalone mode; noCommunication : the communication with the partner is lost; the DHCP server temporarily continues to operate as in normal failover state; partnerDown : the partner is assumed down; the DHCP server instance is leasing addresses from its remote ranges as well as its local ranges; normal : failover is operational; the DHCP server instance is leasing addresses from its local ranges.

Recovery

The required recovery action depends on the new failover state: init | no recovery is required; startUp | shutdown : put the DHCP server instance in state 'inService'; put the DHCP server instance failover facility in state 'inService'; noCommunication | repair the communication with the peer; partnerDown | normal : no recovery is required.

Cause

The tmnxDhcpsLeaseOfferedExpired notification is generated when a DHCP lease that this system had offered to a client, expires while it is still in the 'offered' state, because this system did not receive a DHCP request message from the client.

Effect

The client does not get a lease this time. The client will have to try again if it needs a lease from this system.

The recovery action, if any, will depend on the reason of the expiry.

Cause

The tmnxDhcpSvrHostConflict notification can be generated for hosts configured with a fixed IP address in the local user database. If such a host requests an IP address and the system detects that this IP address has already been handed out to another (dynamic) host, then the tmnxDhcpSvrHostConflict notification is generated.

Cause

The tmnxDhcpSvrLeaseDefaultTimers notification is generated when, for a particular DHCP client, the system has reverted to default lease timer values, because the configuration of the lease timers was inconsistent. The lease renew time T1 and lease rebind time T2 have been reverted to the default values of 1/2 and 2/3 of the lease time.

Cause

The actual length of the DHCP message being built exceeds the maximum size. The maximum size is the minimum of either the maximum DHCP message size or the size provided by the client in the option 'maximum DHCP message size'. A reason can be that too many options are defined on host, pool and subnet levels.

Effect

The Local DHCP Server cannot reply to the client's DHCP requests. The client cannot get an IP address from this DHCP Server.

Recovery

Reduce the number of DHCP options defined on host, pool and subnet levels. Or, if possible, modify the client's DHCP configuration to increase the 'maximum DHCP message size'.

Cause

The tmnxDhcpSvrNoSubnetFixAddr notification can be generated for hosts configured with a fixed IP address in the local user database. If such a host requests an IP address and the system cannot find a matching subnet in this server instance for this IP address, then the tmnxDhcpSvrNoSubnetFixAddr notification is generated, and the request is dropped.

Effect

This DHCP server instance cannot lease any addresses.
