DHCP/4/DHCP_ALLOC_ADDRESS
Message
DHCP/4/DHCP_ALLOC_ADDRESS: Result of IP address allocation from the DHCP server to wireless users.[WLAN_STA_INFO_IP_CONNECTION]ACMAC:[STRING];ACNAME:[STRING];APMAC:[STRING];APNAME:[STRING];USER:[STRING];MAC:[STRING];TIME:[STRING];ZONE:[STRING];DAYLIGHT:[STRING];ERRCODE:[STRING];RESULT:[STRING]
Description
The log indicates the result of IP address allocation by a device functioning as a DHCP server to wireless users.
If a large number of such logs are displayed, other logs may be difficult to view. You can run the info-center filter-id bymodule-alias DHCP DHCP_ALLOC_ADDRESS command in the system view to shield such logs.
Parameters
Parameter Name | Parameter Meaning |
---|---|
ACMAC |
MAC address of an AC. |
ACNAME |
System name of an AC. |
APMAC |
MAC address of an AP. |
APNAME |
System name of an AP. |
USER |
Name of a wireless user. |
MAC |
MAC address of a wireless user. |
TIME |
Time when a log is recorded, in seconds. (The seconds are calculated starting from 00:00:00 on January 1, 1970.) |
ZONE:UTC |
Time zone. |
DAYLIGHT |
Whether the daylight saving time (DST) is used.
|
ERRCODE RESULT |
Error code. IP address allocation result. |
Possible Causes
When an AC, Fat AP, or cloud AP functions as a DHCP server, the AP through which a wireless user goes online, SSID of the user, and other user information can be obtained and recorded in this log. The following table lists the mapping relationships between error codes (ERRCODE) and address allocation results (RESULT) in logs.
ERRCODE |
RESULT |
Description |
Possible Causes |
---|---|---|---|
0 |
Success |
An IP address is successfully allocated. |
– |
102 |
DHCP IP POOL IS OUTFLOW(Pool name:name, the idle address num:num) |
There is no idle IP address in the address pool. Parameters in the brackets indicate the address pool name and number of idle IP addresses. |
No IP address is available for allocation in the address pool. You can run the display ip pool command to check the number of idle IP addresses. Here, the command output indicates that the number of idle IP addresses is 0. |
103 |
DHCP IP POOL LOCKED(Pool name:name) |
The address pool is locked. The parameter in the brackets indicates the address pool name. |
The address pool is locked using the lock command in the address pool view. |
104 |
NOT FIND IP POOL (Receive from interface:if, interface ip:ip. Relay ip:ip. Expect ip:ip) |
The address pool corresponding to the client-expected IP address is not found. Parameters in the brackets indicate the Layer 3 interface that receives the DHCP Request packet, IP address of the interface, IP address of the DHCP relay agent, and client-expected IP address. |
|
105 |
INCORRECT REQUEST IP OR MAC (Ip:ip MAC:mac) |
The DHCP server cannot allocate the client-expected IP address. Parameters in the brackets indicate the client-expected IP address and client's MAC address. |
|
106 |
IP CONFLICTED(The conflict ip:ip) |
An IP address conflict occurs. The parameter in the brackets indicates the conflicted IP address. |
An IP address conflict is detected when the DHCP server allocates an IP address to a client. The address pool then sets the IP address status to conflicting and allocates a new IP address to the client. |
If the client-expected IP address is displayed as 255.255.255.255, the client does not expect any specific IP address.
Procedure
- If there is no idle IP address in the address pool, you are advised to expand the address pool or shorten the address lease time.
- If no corresponding address pool is configured, configure the address pool.
- If the address pool is locked, determine the reason why it is locked. If the client is a PC, the PC typically applies for a new IP address in four-message exchange mode.
- If the PC cannot obtain an IP address or cannot continue to use the original IP address, run the ipconfig /release and ipconfig /renew commands on the PC to enable it to apply for an IP address again. If the client is a mobile phone, delete the SSID recorded on the mobile phone and associate the SSID to the client again.

DHCP/0/DHCPV6RATET_DETECT
Message
DHCP/0/DHCPV6RATET_DETECT: The rate of DHCPV6 packets exceeds the speed limit. [INTEGER] packets have been discarded.
Description

Possible Causes
DHCPv6 messages exceed the rate and the number of discarded DHCPv6 messages reaches the threshold.
Procedure
- Run the display this include-default | include dhcpv6 packet-rate drop-alarm
threshold command in the system view to check the alarm
threshold for the number of DHCPv6 messages discarded when the rate
