Use the undo arp max-learning-num command to restore the default. By default, the maximum number of dynamic ARP entries that an interface can learn is 1024. When the number argument is set to 0, the interface is disabled from learning dynamic ARP entries. Examples # Specify VLAN-interface 40 to learn up to 500 dynamic ARP entries.
Page 11: Arp Timer Aging

NOTE:  A static ARP entry is effective when the switch works normally. However, when the VLAN or VLAN interface to which an ARP entry corresponds is deleted, the entry, if long, will be deleted, and if short and resolved, will become unresolved.

Page 30: Dhcp Server Detect

undo dhcp select server global-pool [ subaddress ] View Interface view Default level 2: System level Parameters subaddress: Supports secondary address allocation. When the DHCP server and client are on the same network segment, the server preferably assigns an IP address from an address pool that resides on the same subnet as the primary IP address of the server interface (connecting to the client).

Parameters None Description Use the dhcp server detect command to enable unauthorized DHCP server detection. Use the undo dhcp server detect command to disable the function. By default, the function is disabled. With this function enabled, upon receiving a DHCP request, the DHCP server will resolve from the request the IP addresses of DHCP servers which ever offered IP addresses to the DHCP client and the receiving interface.
Page 32: Dhcp Server Ip-pool

Using the dhcp server forbidden-ip command repeatedly can exclude multiple IP address ranges from allocation. Related commands: display dhcp server forbidden-ip, dhcp server ip-pool, network, and static-bind ip- address.

Page 34: Dhcp Server Relay Information Enable

To avoid IP address conflicts, the DHCP server checks whether an IP address is in use before assigning it to a DHCP client. The DHCP server pings the IP address to be assigned by using ICMP. If the server gets a response within the specified period, the server selects and pings another IP address.
Page 35: Display Dhcp Server Conflict
