Introduction to IPv6
Configurable IPv6 Security
IP Preserve
IP Preserve operation preserves both the IPv4 and IPv6 addresses configured
on VLAN 1 (the default VLAN) when a configuration file is downloaded to the
switch using TFTP. Refer to “IP Preserve for IPv6” on page 5-23.
Multicast Listener Discovery (MLD)
MLD operates in a manner similar to IGMP in IPv4 networks. In the factory
default state (MLD disabled), the switch floods all IPv6 multicast traffic it
receives on a given VLAN through all ports on that VLAN except the port
receiving the inbound multicast traffic. Enabling MLD imposes management
controls on IPv6 multicast traffic to reduce unnecessary bandwidth usage.
MLD is configured per- VLAN. For information on MLD, refer to the chapter
titled “Multicast Listener Discovery (MLD) Snooping”.
Web Browser Interface
For the web browser interface, software release K.13.01 adds the following
IPv6 functionality:
■ configure and display IPv6 addressing
■ ping6 diagnostic operation
Configurable IPv6 Security
This section outlines the configurable IPv6 security features supported in
software release K.13.01. For further information on these features, refer to
the indicated pages.
SSHv2 on IPv6
SSHv2 provides for the authentication between clients and servers, and
protection of data integrity, and privacy. It is used most often to provide a
secure alternative to Telnet and is also used for secure file transfers (SFTP
and SCP). Software release K.13.01 with SSHv2 on IPv6 extends to IPv6
devices the SSH functionality that has been previously available on ProCurve
switches running IPv4. This means that SSH version 2 connections are
