How is an AR used as the DHCP server enabled to record logs when the DHCP server allocates IP addresses

20

A Huawei AR records logs when IP addresses are allocated through DHCP. The logs are stored in a non-TXT file. Perform the following configurations:
- Interface-based
[Huawei] interface gigabitethernet 1/0/0
[Huawei-GigabitEthernet1/0/0] dhcp select interface
[Huawei-GigabitEthernet1/0/0] dhcp server logging //Enable the DHCP server to record logs when the DHCP server allocates IP addresses.
- Global mode
[Huawei] ip pool global
[Huawei-ip-pool-global] logging //Enable the DHCP server to record logs when the DHCP server allocates IP addresses.

How does an AR used as the DHCP server allocate IP addresses to many DHCP clients
When an AR functions as a DHCP server, you can enlarge the address pool range and shorten the lease of IP addresses to allow DHCP clients to quickly connect to and disconnect from the network.

Method used to configure DHCP relay on the AR
When the DHCP server and DHCP clients are on different network segments, the DHCP relay agent can be configured so that the DHCP server can assign IP addresses to the DHCP clients. Procedure: 1. Configure the router # sysname Router # dhcp enable //Enable the DHCP function. # ip pool ip-pool1 gateway-list 10.10.1.1 //Set the gateway IP address. network 10.10.1.0 mask 255.255.255.128 //Specify the range of IP addresses that can be dynamically allocated in the global address pool. excluded-ip-address 10.10.1.2 //Set the IP address 10.10.1.2 that is not assigned automatically in the address pool. excluded-ip-address 10.10.1.4 //Set the IP address 10.10.1.4 that is not assigned automatically in the address pool. dns-list 10.10.1.2 //Configure the IP address of the DNS server for the DHCP client. nbns-list 10.10.1.4 //Configure the IP address of the NetBIOS server for the DHCP client. lease day 10 hour 12 minute 0 //Set the IP address lease to 10 days and 12 hours. domain-name huawei.com //Set the domain name to huawei.com. static-bind ip-address 10.10.1.5 mac-address fc12-2567-ce34 //Assign a fixed IP address to the PC_AD. # ip pool ip-pool2 gateway-list 10.10.1.129 //Set the gateway IP address. network 10.10.1.128 mask 255.255.255.128 //Specify the range of IP addresses that can be dynamically allocated in the global address pool. dns-list 10.10.1.2 //Configure the IP address of the DNS server for the DHCP client. lease day 5 hour 0 minute 0 //Set the IP address lease to 5 days. domain-name huawei.com //Set the domain name to huawei.com. # interface GigabitEthernet0/0/0 ip address 10.10.1.1 255.255.255.128 dhcp select global //Configure the global address pool mode. # interface GigabitEthernet0/0/1 ip address 10.10.1.129 255.255.255.128 dhcp select global //Configure the global address pool mode. 2. Verify the configuration. Run the display ip pool command on the router to check the IP address pool configuration.

How do I view IP address allocation in the DHCP server address pool
Run the display ip pool [ { interface interface-pool-name | name ip-pool-name } [ start-ip-address [ end-ip-address ] | all | conflict | expired | used ] ] command to view IP address allocation.

Method used to configure the logging function when IP addresses are allocated through DHCP on the AR
Huawei AR series routers record logs when IP addresses are allocated through DHCP. The logs are stored in a non-TXT file. The configuration procedure is as follows. -Interface address pool [Huawei] interface gigabitethernet 1/0/0 [Huawei-GigabitEthernet1/0/0] dhcp select interface [Huawei-GigabitEthernet1/0/0] dhcp server logging //Enable the DHCP server to record logs when the DHCP server allocates IP addresses. -Global address pool [Huawei] ip pool global [Huawei-ip-pool-global] logging //Enable the DHCP server to record logs when the DHCP server allocates IP addresses.

How does the AR used as the DHCP server ensure that users obtain the correct DHCP server address
To ensure that users obtain the correct DHCP server address when the Huawei AR serves as the DHCP server, you can configure DHCP snooping on the switch or the DHCP relay agent that is closest to the users.
