Configuring IP Packet Check

Configuring IP Packet Check

Context

IPSG can check IP packets based on VLANs or interfaces .

NOTE:

If IP packet check is configured on an interface and in a VLAN, check items configured on the interface take effect.

Procedure

  • In the VLAN:
    1. Run system-view

      The system view is displayed.

    2. Run vlan vlan-id

      The VLAN view is displayed.

    3. Run ip source check user-bind enable

      IP packet check is enabled.

      By default, IP packet check is disabled in the VLAN.

    4. Run ip source check user-bind check-item { ip-address | mac-address | interface }*

      IP packet check items are configured.

      By default, the device checks the source IP address, source MAC address, VLAN ID, and interface number in IP packets in the VLAN view.

      NOTE:

      This command is valid only for dynamic binding entries. IPSG enables the device to check all the static binding entries.

    5. Run commit

      The configuration is committed.

  • On the interface:
    1. Run system-view

      The system view is displayed.

    2. Run interface interface-type interface-number

      The interface view is displayed.

    3. Run ip source check user-bind enable

      IP packet check is enabled.

      By default, IP packet check is disabled on the interface.

    4. Run ip source check user-bind check-item { ip-address | mac-address | vlan }*

      IP packet check items are configured.

      By default, the device checks the source IP address, source MAC address, VLAN ID, and interface number in IP packets in the interface view.

      NOTE:

      This command is valid only for dynamic binding entries. IPSG enables the device to check all the static binding entries.

    5. Run commit

      The configuration is committed.
