Catalyst 4500 Series Switch, Cisco IOS Software Configuration Guide - Cisco IOS XE 3.9.xE and IOS 15.2(5)Ex
Chapter 1 Product Overview
Layer 2 Software Features
Under the Summary Steps, steps 3 and 4 should read as follows:
ipv6 pim [vrf vrf-name] bsr candidate bsr ipv6-address [hash-mask-length] [priority
priority-value] [scope scope-value] [accept-rp-candidate access-list-name]
ipv6 pim [vrf vrf-name] bsr candidate rp ipv6-address [group-list access-list-name] [priority
priority-value] [interval seconds] [bidir]
Under the Details Steps, Step 3 should read:
ipv6 pim [vrf vrf-name] bsr candidate bsr ipv6-address [hash-mask-length] [priority
priority-value] [scope scope-value] [accept-rp-candidate access-list-name]
Example:
Device(config)# ipv6 pim bsr candidate bsr 2001:DB8:1:1:4 scope 6
Under the Details Steps, Step 4 should read:
ipv6 pim [vrf vrf-name] bsr candidate rp ipv6-address [group-list access-list-name] [priority
priority-value] [interval seconds] [bidir]
Example:
Device(config)# ipv6 pim bsr candidate rp 2001:DB8:1:1:1 group-list list
In the section "Configuring BSR Devices to Announce Scope-to-RP Mappings,” the keyword
scope scope-value should be removed from Step 3, both under Summary and Detail Steps.
In the section “Additional References section,” it would be helpful to reference RFC 5059.
IPv6 Multicast Listen Discovery (MLD) and Multicast Listen Discovery
Snooping
MLD is a protocol used by IPv6 multicast devices to discover the presence of multicast listeners
(nodes that want to receive IPv6 multicast packets) on its directly attached links and to discover
which multicast packets are of interest to neighboring nodes. MLD snooping is supported in two
different versions: MLD v1 and MLD v2. Network switches use MLD snooping to limit the flood
of multicast traffic, causing IPv6 multicast data to be selectively forwarded to a list of ports that want
to receive the data, instead of being flooded to all ports in a VLAN. This lessens the load on devices
in the network, minimizing unnecessary bandwidth on links, enabling efficient distribution of IPv6
multicast data.
For information on configuring multicast services, see Chapter 38, “Configuring IP Multicast.
Jumbo Frames
The jumbo frames feature allows the switch to forward packets as large as 9216 bytes (larger than the
IEEE Ethernet MTU), rather than declare those frames “oversize” and discard them. This feature is
typically used for large data transfers. The jumbo frames feature can be configured on a per-port basis
on Layer 2 and Layer 3 interfaces. The feature is supported only on the following hardware:
WS-X4306-GB: all ports
WS-X4232-GB-RJ: ports 1-2
WS-X4418-GB: ports 1-2
WS-X4412-2GB-TX: ports 13-14
