Enabling Or Disabling Mld Snooping - Cisco WS-CBS3032-DEL Software Configuration Manual

Chapter 25 Configuring IPv6 MLD Snooping

Enabling or Disabling MLD Snooping

By default, IPv6 MLD snooping is globally disabled on the switch and enabled on all VLANs. When
MLD snooping is globally disabled, it is also disabled on all VLANs. When you globally enable MLD
snooping, the VLAN configuration overrides the global configuration. That is, MLD snooping is enabled
only on VLAN interfaces in the default state (enabled).
You can enable and disable MLD snooping on a per-VLAN basis or for a range of VLANs, but if you
globally disable MLD snooping, it is disabled in all VLANs. If global snooping is enabled, you can
enable or disable VLAN snooping.
Beginning in privileged EXEC mode, follow these steps to globally enable MLD snooping on the switch:
Command
Step 1
configure terminal
Step 2 ipv6 mld snooping
Step 3 end
Step 4 copy running-config startup-config
To globally disable MLD snooping on the switch, use the no ipv6 mld snooping global configuration
command.
Beginning in privileged EXEC mode, follow these steps to enable MLD snooping on a VLAN.
Note When the IPv6 multicast router is a Catalyst 6500 switch and you are using extended VLANs (in the
range 1006 to 4094), IPv6 MLD snooping must be enabled on the extended VLAN on the Catalyst 6500
switch in order for the switch to receive queries on the VLAN. For normal-range VLANs (1 to 1005), it
is not necessary to enable IPv6 MLD snooping on the VLAN on the Catalyst 6500 switch.
