HUAWEI-ETHARP-MIB

HUAWEI-ETHARP-MIB

Functions Overview

To protect users against attacks, the following measures are taken:

  • ARP entry restriction

  • Anti-ARP attack

  • Network segment scan

The HUAWEI-ETHARP-MIB has the following functions:

  • Configuring ARP entry restriction

  • Checking the entry restriction of each interface

  • Checking the ARP entry learned based on the interface or the interface + VLAN ID

  • Checking the number of ARP packets that are discarded because of the entry restriction or timestamp suppression

  • Setting the time suppression rate based on the slot number

  • Setting to learn only the Response packet replied to the sent Request packet

  • Setting to send the Trap message when the suppression rate is exceeded

  • Setting the interval for sending alarm logs

You can query and set parameters related to the ARP aging on the HUAWEI-ARP-MIB, and now only the ARP aging detection mode and the type of ARP aging detection packets are supported.

The following modules can be set through the NMS:

Timestamp suppression module

  • The NMS supports the configuration of logging ARP attack defense and the interval of Trap messages.

  • The NMS supports the configuration of strict ARP learning.

  • The NMS supports the configuration of timestamp suppression rate.

ARP entry restriction module

  • Each ARP entry restriction has the corresponding private MIB, through which the NMS can query the number of current entries.

  • ARP entry restriction can be set through the NMS.

  • The NMS can query ARP entries or the statistics of ARP entries through the MIB.

The OID of the root object is:

iso(1).org(3).dod(6).internet(1).private(4).enterprises(1).huawei(2011).huaweiMgmt(5).hwDatacomm(25).hwEthernetARPMIB(123)

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.
