Introduction to IPv6

IPv6 Scalability

SNMP

When IPv6 is enabled on a VLAN interface, you can manage the switch from a network management station configured with an IPv6 address. Refer to “SNMP Management for IPv6” on page 5-20.

Loopback Address

Like the IPv4 loopback address, the IPv6 loopback address (::1) can be used by the switch to send an IPv6 packet to itself. However, the IPv6 loopback address is implicit on a VLAN and cannot be statically configured on any VLAN. Refer to “Loopback Address” on page 3-24.

Debug/Syslog Enhancements

Includes new options for IPv6. Refer to “Debug/Syslog for IPv6” on page 8-12.

IPv6 Scalability

As of software release K.13.01, the switches covered by this guide support the following:

■Dual stack operation (IPv4 and IPv6 addresses on the same VLAN).

■Maximum of 512 VLANs with IPv4 and IPv6 addresses in any combination.

■Up to 2048 VLANs configured on the switch.

■Maximum of 2048 active IPv6 addresses on the switch, in addition to a maximum of 2048 IPv4 addresses. (“Active IPv6 addresses” includes the total of all preferred and non-preferred addresses configured statically, through DHCPv6, and through stateless autoconfiguration. Excluded from “Active IPv6 Addresses” is the link-local address assigned to each VLAN, and “on- link” prefixes received as part of a router advertisement.)

■Maximum of 32 IPv6 addresses on a VLAN.

■Maximum of 10,000 IPv6 routes.

For more information on VLAN and route scalability on the switches covered by this guide, refer to the appendix titled “Scalability: IP Address, VLAN, and Routing Maximum Values” in the Management and Configuration Guide for your switch.
