display dhcpv6 statistics

Function

The display dhcpv6 statistics command displays DHCPv6 packet statistics.

Format

display dhcpv6 statistics

Parameters

None

Views

All views

Default Level

1: Monitoring level

Usage Guidelines

The device may become faulty when running the DHCPv6 service. Some fault location methods are required for administrators or device maintenance personnel to locate faults quickly. The most convenient and effective method is to provide statistics about packets and packet loss reasons. Run the display dhcpv6 statistics command to view DHCPv6 packet statistics.

Example

# View DHCPv6 packet statistics.

<Huawei> display dhcpv6 statistics

Max-user limit or Add bindtable failed

Information displayed if the DHCPv6 service is abnormal. The displayed information includes:
  • Max-user limit: Total number of DHCP packets discarded because the maximum number of users is exceeded.
  • Add bindtable failed: Total number of DHCP packets discarded because dynamic binding entries fail to be added.
  • High cpu occupancy: Total number of DHCP packets discarded because the CPU usage is excessively high.
  • Port blocked: Total number of DHCP packets discarded because the inbound interface is blocked.
  • Rx buffers full: Total number of DHCP packets discarded because the remaining queue length is shorter than the reserved threshold.
  • L2fdb lookup failed: Total number of DHCP packets discarded because entries fail to be queried.
  • Bad vlan id: Total number of DHCP packets discarded because the VLAN ID is incorrect.
  • Memory exhausted: Total number of DHCP packets discarded because the memory is exhausted.
  • L3if protocol down: Total number of DHCP packets discarded because the Layer 3 protocol of the source interface goes Down.
  • Rate limit: Total number of DHCP packets discarded because rates of the packets exceed the limit.
  • Bad packet length: Total number of DHCP packets discarded because the packet length is incorrect.
  • Bad ip header length: Total number of DHCP packets discarded because the IP header length is incorrect.
  • Bad ip header checksum: Total number of DHCP packets discarded because the checksum of the IP header is incorrect.
  • Bad udp checksum: Total number of DHCP packets discarded because the checksum of the UDP header is incorrect.
  • Hops exceeded: Total number of DHCP packets discarded because the number of next hops is incorrect.
  • Bad magic cookie: Total number of DHCP packets discarded because the magic-cookie field is incorrect.
  • Duplicate option: Total number of DHCP packets discarded because the option fields are duplicate.
  • Bad option length: Total number of DHCP packets discarded because the option field length is incorrect.
  • End option absent: Total number of DHCP packets discarded because of the incorrect end option.
  • Dest-port equals source: Total number of DHCP packets discarded because the source interface is also the outbound interface.
  • Bad chaddr: Total number of DHCP packets discarded because the MAC address of the client is incorrect.
  • Bad giaddr: Total number of DHCP packets discarded because the relay gateway is incorrect.
  • Bad request: Total number of DHCP packets discarded because the request packets are incorrect.
  • Bad reply: Total number of DHCP packets discarded because the response packets are incorrect.
  • Bad dest udp-port: Total number of DHCP packets discarded because the destination interface is incorrect.
  • Bad message type: Total number of DHCP packets discarded because of incorrect destination interfaces.
  • L2fdb lookup failed: Total number of incoming DHCP packets discarded because entries fail to be queried.
  • Client transfered: Total number of DHCP packets discarded due to interface flapping.
  • Bad original interface: Total number of DHCP packets discarded because dynamic binding entries are added.
  • Bad client-id: Total number of DHCP packets discarded because the client ID is incorrect.
