mld-snooping-show

Multicast Listener Discovery (MLD) is a Layer 3 multicast protocol used between IPv6 hosts, and routers similar to how IGMP is used for IPv4. MLD snooping allows a switch to examine MLD packets, and make forwarding decisions based on their content.

MLD snooping constrains IPv6 multicast traffic at Layer 2 by configuring Layer 2 LAN ports dynamically to forward IPv6 multicast traffic only to those ports that want to receive it.


Syntax   mld-snooping-show

Defaults   None.

Access   CLI

History   

Version 2.3

Command introduced.

Version 2.4

The parameters version and snoop-link introduced.

Version 2.5.2

The parameters version, snoop-linklocal and snoop-nd deprecated.

The parameters mldv1-vlans, mldv2-vlans, snoop-linklocal-vlans, and snoop-nd-vlans introduced.

Version 3.1.0

The parameters query-interval and query-max-response-time added.

Usage   The default behavior, when MLD Snooping is not configured, multicast traffic is forwarded to all the switch ports, impacting switch performance.

Examples  To display the format for all options for the local switch, use the following command:

mldv2-vlans:                1-4092

snoop-linklocal-vlans:      none

snoop-nd-vlans:             none

query-interval(s):          60

query-max-response-time(s): 10
