Address Parse

In this interface, you can set and query parameters related to address parse.

Navigation Path

In the NE Explorer, click the NE and choose Configuration > Packet Configuration > Control Plane Configuration > Address Parse from the Function Tree.

Guideline

The configuration of the address resolution refers to the creation of the static ARP entries.

Buttons

Button	Description
Clear	Clear all the dynamic ARP in the ARP table items. NOTICE: Exercise caution when performing this operation to avoid service interruption.
Switch to Static Type	During the equipment operation phase, you can change dynamic entries in the ARP table to static entries to improve stability of tunnels.

Parameters

**Table 1** Descriptions of the parameters for Address Parse
Parameter	Value	Description
ARP List IP Address	Example: 129.9.1.23	Configure the IP address in the ARP list.
ARP List MAC	Example: 1C-C4-31-88-1C-C4	Configure the MAC address corresponding to the IP address in the ARP list.
ARP List Type	Static, Dynamic	Display the type of the ARP list. Address resolution protocol (ARP) is used to map the IP address (alias: logical address) at the network layer into the MAC address (alias: physical address) at the data link layer. Static ARP means that there is a fixed mapping relation between the IP address and the MAC address, and thus you cannot adjust this relation dynamically on the equipment or the router. For the static ARP, you need to manually create a table that is stored on each piece of equipment in the network. The static ARP table is used in the following scenarios: When a packet is transmitted to a destination address beyond the local network segment, this packet is bound with a specific network interface card (NIC) in order to be forwarded through this gateway. To filter out certain illegal IP addresses, you can bind these addresses with an MAC address that does not exist to realize the filtering. Dynamic ARP means that the mapping relation between the IP address and the MAC address is constantly refreshed and adjusted through address learning. Changing the NIC or moving the host to another network usually changes the physical address. The corresponding MAC address can be obtained in a timely manner based on the dynamic ARP address resolution.
