System impact

New DHCP users cannot obtain IP addresses from the DHCP server.

Status control

ON

CLI: Use the snmp-agent trap enable dhcp server address-exhaust command.

OFF

CLI: Use the undo snmp-agent trap enable dhcp server address-exhaust command.

Object

OID (object name)	Description	Index	Type	Value range

Notification triggers

This notification is generated when the address usage of an address pool has exceeded the threshold. The address usage of an address pool is read every 5 minutes.

System impact

If the DHCP server continues to assign IP addresses from the address pool to clients, the address pool might run out of addresses. As a result, new DHCP users cannot obtain IP addresses and thus cannot come online.

Recommended action

To resolve this issue:

1.Use the display ip pool command in any view to check whether the address usage threshold specified in the current address pool is appropriate.

  - If the address usage threshold is too low, increase the threshold.

  - If the address usage threshold is appropriate, proceed to step 2.

2.Use the display dhcp server statistics command in any view to view the address usage of the current address pool and the number of assignable addresses in the current address pool.

  - If the assignable addresses are insufficient, use one of the following methods to increase address resources:

Add the current address pool and other address pools to an address pool group.

Add secondary network segments for dynamic address allocation in the current address pool.

  - If the assignable addresses are sufficient, keep observing the address usage of the current address pool. When the address pool has a high address usage, increase address resources timely to ensure that new DHCP users can obtain addresses.

3.If the issue persists, collect alarm information, log messages, and configuration data, and then contact H3C Support for help.

  - If the address pool does not have any assignable addresses, use one of the following methods to increase address resources:

Add the current address pool and other address pools to an address pool group.

Add secondary network segments for dynamic address allocation in the current address pool.

If the issue persists, proceed to step 3.

2.Verify that all DHCP settings are configured correctly. If the issue persists, proceed to step 3.
