hwEthARPLimitTable

hwEthARPLimitTable

The creation, deletion, or modification of the entries in this table, or access to the attributes of these entries can implement ARP entry restriction based on the Layer 3 interface index or Layer 2 interface index + VLAN ID.

The indexes of this table are hwEthARPLimitCfgIfindex, hwEthARPVLANFirst, and hwEthARPVLANLast.

hwEthARPLimitCfgIfindex

InterfaceIndex

Not-accessible

This object indicates the interface to be configured with entry restriction.

This object is implemented as defined in the corresponding MIB files.

1.3.6.1.4.1.2011.5.25.123.1.13.1.2

hwEthARPVLANFirst

Integer32( 0..4094 )

Not-accessible

The value of this object identifies the first value of the VLAN ID range. The VLAN ID of a Layer 3 interface is 0.

This object is implemented as defined in the corresponding MIB files.

1.3.6.1.4.1.2011.5.25.123.1.13.1.3

hwEthARPVLANLast

Integer32( 0..4094 )

Not-accessible

The value of this object identifies the second value of the VLAN ID range. The VLAN ID of a Layer 3 interface is 0.

This object is implemented as defined in the corresponding MIB files.

1.3.6.1.4.1.2011.5.25.123.1.13.1.4

hwEthARPLimitNum

Integer32( 1..2147483647)

Read-create

The value of this object identifies the maximum number of ARP entries.

Integer32(1..16384)

1.3.6.1.4.1.2011.5.25.123.1.13.1.5

hwEthARPLimitRowStatus

RowStatus

Read-create

This object indicates the row status.

This object is implemented as defined in the corresponding MIB files.

Creation Restriction

Configure ARP entry restriction on the Layer 2 interface. The following is an example:

The VLANs from Vlan 1 to Vlan 5 of the Layer 2 interface are configured with ARP entry restriction. In addition, the VLANs from Vlan 3 to Vlan 8 of this Layer 2 interface need to be configured with ARP entry restriction.

  • You can only use active (1) to modify this entry because the VLANs from Vlan 3 to Vlan 5 of this Layer 2 interface are configured with ARP entry restriction.

  • You can only use createAndGo (4) to create this entry because the VLANs from Vlan 6 to Vlan 8 of this Layer 2 interface are not configured with ARP entry restriction.

If conflict occurs, choose createAndGo (4).

Modification Restriction

Configure ARP entry restriction on the Layer 2 interface. The following is an example:

The VLANs from Vlan 1 to Vlan 5 of the Layer 2 interface are configured with ARP entry restriction.

If the VLANs from Vlan 2 to Vlan 5 of this Layer 2 interface need to be configured with ARP entry restriction, you can only use active (1) to modify this entry.

Deletion Restriction

To keep this MIB the same as command lines, if the index is valid, that is, the interface exists, hwEthARPLimitTable can be successfully deleted regardless of whether the interface corresponding to this index is configured with ARP entry restriction.

If the VLANs from Vlan 1 to Vlan 5 of the Layer 2 interface are configured with ARP entry restriction, note the following:

  • On this MIB, ARP entry restriction configured on the VLANSs from Vlan 3 to Vlan 8, and from Vlan 3 to Vlan 5 of this Layer 2 interface can be successfully deleted.

  • On this MIB, ARP entry restriction configured on the VLANSs from Vlan 1 to Vlan 4 of this Layer 2 interface can be successfully deleted.

Access Restriction

When setting or querying the maximum number of ARP packets on a Layer 3 interface, fill in VLAN ID with 0.

When configuring a Layer 2 interface with ARP entry restriction, use a VLAN ID range to configure the other VLAN ID range. However, when querying the maximum number of ARP packets on a specified VLAN of a specified interface, ensure that the values of hwEthARPVLANFirst and hwEthARPVLANLast are the same and valid.
