Disabling error and warning messages
Disabling error and warning messages
Error or warning messages are printed when the device runs out of software resources or when it receives packets with the wrong checksum or groups. These messages are rate limited. You can turn off these messages by entering the ipv6 multicast
device(config)#ipv6 multicast
Syntax: [no] ipv6 multicast
Configuring the MLD mode for a VLAN
You can configure a VLAN for either the active or passive (default) MLD mode. The VLAN setting overrides the global setting:
•Active - In active MLD mode, the device actively sends out MLD queries to identify IPv6 multicast groups on the network, and makes entries in the MLD table based on the group membership reports it receives from the network.
•Passive - In passive MLD mode, the device forwards reports to router ports that receive queries. MLD snooping in the passive mode does not send queries. However, it does forward queries to the entire VLAN.
To set the MLD mode for VLAN 20 to active, enter the following commands.
device(config)#vlan 20
Syntax: [no] multicast6 [active passive]
The default mode is passive.
Disabling MLD snooping for the VLAN
When MLD snooping is enabled globally, you can disable it for a specific VLAN. For example, the following commands disable MLD snooping for VLAN 20. This setting overrides the global setting for VLAN 20.
device(config)#vlan 20
Syntax: [no] multicast6
Configuring the MLD version for the VLAN
You can specify the MLD version for a VLAN. For example, the following commands configure VLAN 20 to use MLDv2.
device(config)#vlan 20
Syntax: [no] multicast6 version [1 2]
When no MLD version is specified, the
