Issue/Introduction

By default, the ProxySG automatically generates link-local IPv6 addresses on all interfaces. This feature can be disabled.
 

Cause

This is a default feature of IPv6.

Resolution

Use the following CLI commands:

> enable
# conf t
# ipv6 auto-linklocal disable


The ipv6 auto-linklocal command enables or disables automatic generation of link-local addresses on all interfaces. When this parameter is enabled (as it is by default), individual interface configuration values override this setting. When this setting is disabled, it is disabled for all interfaces (regardless of the per-interface setting). After link-local addresses are generated for the ProxySG interfaces,they will stay configured until they are manually removed using the no ip-address command or until the ProxySG is rebooted.

Or for a specific interface:
SGOS#(config interface interface_number) ipv6 auto-linklocal {enable | disable}

Enables or disables the automatic generation of link-local addresses for this interface. After a link-local address is generated for an interface, it remains configured until it is manually removed using the no ip-address command or until the ProxySG is rebooted.
