savi max-binding-table

Function

The savi max-binding-table command sets the maximum number of SAVI binding entries on an interface.

The undo savi max-binding-table command restores the default maximum number of SAVI binding entries on an interface.

By default, the maximum number of SAVI binding entries is the same as the number of binding entries supported by the device.

Usage Guidelines

Usage Scenario

An SAVI binding table is a set of the ND snooping binding table and DHCPv6 snooping binding table. When the sum of ND snooping binding entries and DHCPv6 snooping binding entries on an interface reaches the configured maximum number of SAVI binding entries, subsequent users cannot connect to the network. After the maximum number of SAVI binding entries is set, the device does not process many ND packets and DHCPv6 packets with invalid source addresses to defend against attacks.

Prerequisites

Ensure that SAVI has been enabled globally using the savi enable command.

Example

# Set the maximum number of SAVI binding entries on the GE0/0/1 to 8.

<HUAWEI> system-view
[HUAWEI] savi enable
[HUAWEI] interface gigabitethernet 0/0/1
[HUAWEI-GigabitEthernet0/0/1] savi max-binding-table 8
