Static ARP Table

You can query and configure static ARP entries.

Context

ARP entries can be maintained dynamically or manually. Manually configured mappings from IP addresses to MAC addresses are static ARP entries. You can query, add, modify, and delete ARP entries manually.

CAUTION:

Static ARP entries are always valid when a switch works normally. When a VLAN is deleted, the ARP entries of the VLAN are also deleted.

Procedure

• Query static ARP entries.
  1. Choose Service Management > ARP > Static ARP Table in the navigation tree to open the Static ARP Table page.
     NOTE:

     • Table 1 describes the parameters on the Static ARP Table page.
     • The Static ARP Table page does not contain the ARP Type drop-down list box.

  2. Set the search criteria.
  3. Click Query to display all matching records.
• Create a static ARP entry.
  1. Choose Service Management > ARP > Static ARP Table in the navigation tree to open the Static ARP Table page.
  2. Click New to open the Create Static ARP page.

     Table 1 describes the parameters on the Create Static ARP page.

     Table 1 Create Static ARP

     Parameter	Description
     Destination IP	Indicates the destination IP address in the new ARP entry, for example, 10.10.10.1. NOTE: This parameter cannot be set to the virtual IP address of a VRRP group on a VLANIF interface. Otherwise, an incorrect host route will be created, causing forwarding errors.
     Destination MAC	Indicates the Ethernet MAC address mapping the IP address. The value is in the format H-H-H.
     VLAN ID	Indicates the VLAN ID corresponding to the IP address. NOTE: If you enter a VLAN ID, the created ARP entry is in the specified VLAN. The VLANIF interface of the VLAN must be in the same network segment as the destination IP address.
     Outgoing	Indicates name of the outbound interface of ARP packets, for example, Ethernet0/0/1. NOTE: The interface must be a member of the specified VLAN.

  3. Set parameters.
     NOTE:

     The destination IP address and the IP address of the outbound interface must be in the same network segment.

  4. Click OK.
• Modify a static ARP entry.
  1. Choose Service Management > ARP > Static ARP Table in the navigation tree to open the Static ARP Table page.
  2. Click to open the Modify Static ARP page.
     NOTE:

     • Table 1 describes the parameters on the Modify Static ARP page.
     • The destination IP address, destination MAC address, and VLAN ID cannot be changed.

  3. Set parameters.
  4. Click OK.
• Delete Static ARP
  1. Choose Service Management > ARP > Static ARP Table in the navigation tree to open the Static ARP Table page.
  2. Select a record that you want to delete and click Delete. The system asks you whether to delete the record.
     NOTE:

     • To select a record, click the check box of the record.
     • To delete records in batches, click the check boxes of the records.

  3. Click OK.
