System impact

New DHCPv6 users cannot obtain IPv6 addresses from the DHCPv6 server.

Status control

ON

CLI: Use the snmp-agent trap enable ipv6 dhcp server address-exhaust command.

OFF

CLI: Use the undo snmp-agent trap enable ipv6 dhcp server address-exhaust command.

Object

OID (object name)	Description	Index	Type	Value range

hh3cDhcp6Server2IpUsageOverflow

Basic information

OID	Event	Type	Severity	Recovery notification	Default status
1.3.6.1.4.1.25506.2.179.2.0.3	The address usage of an IPv6 address pool has exceeded the threshold.	Error	Warning	1.3.6.1.4.1.25506.2.179.2.0.4 (hh3cDhcp6Server2IpUsageOverflowRecov)	ON

 

Notification triggers

This notification is generated when the address usage of an IPv6 address pool has exceeded the threshold.

System impact

If the DHCPv6 server continues to assign IPv6 addresses from the address pool to clients, the address pool might run out of addresses. As a result, new DHCPv6 users cannot obtain IPv6 addresses and thus cannot come online.

Status control

ON

CLI: Use the snmp-agent trap enable ipv6 dhcp server ip-in-use command.

OFF

CLI: Use the undo snmp-agent trap enable ipv6 dhcp server ip-in-use command.

Recommended action

To resolve this issue:

1.Use the display ipv6 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 ipv6 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, replan and increase address pool resources. For example, you can increase address resources as follows:

  - i. Use the ipv6 pool-group command to create an IPv6 address pool group, and then add multiple address pools to the address pool group.

  - ii. Use the undo authorization-attribute ipv6-pool command in ISP domain view to remove the current authorization IPv6 address pool attribute.

  - iii. Use the authorization-attribute ipv6-pool-group command in ISP domain view to specify the IPv6 address pool group for users.

  - 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 DHCPv6 users can obtain addresses.

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

Recommended action

To resolve this issue:

1.Use the display ipv6 dhcp dynamic address command in any view to view the subnets in IPv6 address pools that support dynamic IPv6 subnet allocation.

If the utilization of each subnet is high, use the dynamic utilization mark command to adjust the low utilization mark. This operation will make corresponding address pools to release idle subnets.

If the utilization of each subnet is not high, keep observing the utilization of each subnet. When the subnet utilization is high, increase subnet resources timely to ensure that new DHCPv6 users can obtain addresses.

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

Recommended action

To resolve this issue:

1.Use the display domain command in any view to check whether the authorization-attribute ipv6-pool command is configured.

  - If the command is configured, verify that the access configuration is correct. For more information about this task, see IPoE configuration in Layer 2—WAN Access Configuration Guide.

  - If the command is not configured, proceed to step 2.

2.Use the display ipv6 dhcp server statistics command in any view and check whether the value of the Free IPv6 addresses field is 0 in the command output.

If the value of the Free IPv6 addresses field is 0, perform the following task to increase usable address pool resources:

Use the ipv6 pool-group command to create an IPv6 address pool group, and then add multiple address pools to the address pool group.

Use the undo authorization-attribute ipv6-pool command in ISP domain view to remove the current authorization IPv6 address pool attribute.

Use the authorization-attribute ipv6-pool-group command in ISP domain view to specify the IPv6 address pool group for users.

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