ARP

ARP

Context

The Address Resolution Protocol (ARP) maps IP addresses to MAC addresses.

ARP entries include dynamic and static ARP entries according to the mode in which they are generated.
  • Dynamic ARP entries: are automatically generated and maintained through ARP. Each dynamic ARP entry has a lifetime. Dynamic ARP entries can be updated or overwritten by static ARP entries.
  • Static ARP entries: are configured manually to record mappings between IP addresses and MAC addresses. Mappings cannot be changed dynamically.

Procedure

  • Create a static ARP entry.
    1. Log in to the web NMS and choose IP Service > ARP. The ARP page is displayed. as shown in Figure 13-18.

      Figure 13-18  ARP page

    2. Click Create. In the Create Static ARP Entry dialog box that is displayed, select or enter each parameter to configure a static ARP entry. For description of the parameters, see Table 13-21.

    3. Click OK to complete the configuration.

      Table 13-21  Parameter description of creating static ARP entries

      Parameter

      Description

      IP address

      IP address of a static ARP entry.

      MAC address

      MAC address of a static ARP entry.

      VLAN ID

      ID of the VLAN to which a static ARP entry belongs.

      VPN instance

      Name of a VPN instance.

      NOTE:

      Create a VPN instance before specifying this parameter. For details, see VPN Instance.

      Outbound interface of a static ARP packet. Click . In Select Interface, use either of the following methods to select an outbound interface:
      • Enter keywords in the Interface name text box and click Search. Select an interface in the Interface Name list and click OK.
      • Select an interface in the Interface Name list and click OK.
      NOTE:

      If the selected outbound interface is added to VLAN, and the VLANIF interface corresponding to the VLAN is assigned an IP address, the specified IP address in a static ARP entry should be on the same network segment as the IP address of the VLANIF interface, and the ID of the VLAN to which a static ARP entry belongs should be the same as the ID of the VLAN to which the outbound interface belongs.

  • Delete an ARP entry.
    1. Log in to the web NMS and choose IP Service > ARP. The ARP page is displayed. You can view the configured static ARP entries or the generated dynamic ARP entries.
    2. Select the check box next to the ARP entry to be deleted and click Delete.
    3. In the dialog box that is displayed, click OK to delete the APR entry.
  • Update ARP entries.
    1. Log in to the web NMS and choose IP Service > ARP. The ARP page is displayed. You can view the configured static ARP entries or the generated dynamic ARP entries.
    2. Click Refresh to update ARP entries.
  • Search for an ARP entry.
    1. Log in to the web NMS and choose IP Service > ARP. The ARP page is displayed. You can view the configured static ARP entries or the generated dynamic ARP entries.
    2. Select search items in the two drop-down lists next to Search item.

      • Select Type in the first drop-down list, select Static or Dynamic in the second drop-down list, and click Search to search for an ARP entry according to the type.
      • Select IP address in the first drop-down list, enter the corresponding IP address in the second drop-down list, and click Search to search for an ARP entry according to the IP address.
      • Select MAC address in the first drop-down list, enter the corresponding MAC address in the second drop-down list, and click Search to search for an ARP entry according to the MAC address.
      • Select VPN instance in the first drop-down list, enter the corresponding VPN instance name in the second drop-down list, and click Search to search for an ARP entry according to the VPN instance name.

      For description of the parameters, see Table 13-22.

      Parameter

      Description

      Type

      Type of an ARP entry.
      • Static: a manually configured ARP entry.
      • Dynamic: an automatically generated ARP entry.

      IP Address

      IP address of an ARP entry.

      MAC Address

      MAC address of an ARP entry.

      VLAN ID(Outer/Inner)

      ID of the inner VLAN or outer VLAN that an ARP entry belongs to.

      NOTE:

      Currently, a static ARP entry can only be configured with an outer VLAN ID.

      Outbound Interface

      Outbound interface of an ARP entry.

      VPN Instance

      VPN instance to which an ARP entry belongs.

      Timeout Interval(Minutes)

      Remaining lifetime of an ARP entry, in minutes.

      This parameter is valid only for dynamic ARP entries. Each dynamic ARP entry has a lifetime. When the remaining lifetime of an ARP entry is 0, the ARP entry will be deleted.
