IPv6 First Hop Security

Cisco Sx350 Ph. 2.2.5 Devices - Command Line Interface Reference Guide

646

29

 

Example

The following example enables the switch to specify 2 as the minimum CGA 
security level:

switchxxxxxx(config)# 

ipv6 nd inspection sec-level minimum

 2

29.29 ipv6 nd inspection validate source-mac

To globally enable checking source MAC address against the link-layer address in 
the source/target link-layer option, use the ipv6 nd inspection validate source-mac 
command in Global Configuration mode. To disable this function, use the no form 
of this command.

Syntax

ipv6 nd inspection validate source-mac

no ipv6 nd inspection validate source-mac

Parameters

N/A

Default Configuration

This command is disabled by default.

Command Mode

Global Configuration mode

User Guidelines

When the switch receives an NDP message, which contains a link-layer address in 
the source/target link layer option, the source MAC address is checked against 
the link-layer address. Use this command to drop the packet if the link-layer 
address and the MAC addresses are different from each other.
