mld-static-source-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.

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

Syntax   mld-static-source-show switch name-string group-ip ip-address vlan vlan-id source-ip ip-address host-ip ip-address ports port-list

group-ip ip-address

Specifies the IP address of the group.

vnet vnet-name

Specifies the name of the VNET.

l2-net l2-net-name

Specifies the name of the Layer 2 network.

vlan vlan-id

Specifies the name of the VLAN.

source-ip ip-address

Specifies the IP address of the source.

host-ip ip-address

Specifies the IP address of the host.

ports port-list

Specifies the list of ports.

Formatting Options

format fields-to-display

Display output using a specific parameter. Use all to display all possible output.

parsable-delim character

Display output formatted for machine parsing using a specified delimiter.

sort-asc

Display output in ascending order.

sort-desc

Display output in descending order.

show dups

Display duplicate entries in the output.

layout vertical|horizontal

Format the output in a vertical or horizontal layout.

show-interval seconds-interval

Repeat the show command at a specified interval.

show-headers|
no-show-headers

Display column headers or not.

limit-output number

Limit the display output to a specific number of entries.

count-output

Display the number of entries in the output. This is useful with vRouter show commands.

unscaled

Display full values in the output instead of scaled approximate values.

raw-int-values

Display integer values instead of mapped values

sum-by

Aggregate output by specific parameters. If sum-by fields are specified, records that have the same value in sum-by fields are combined and displayed as one aggregate record. NOTE: This option is only available for show commands that collect statistics such as connection-stats-show.

Defaults   None.

Access   CLI

History   Command introduced in Version 2.3.

Version 2.3

Command introduced.

Version 2.4.1

The parameter, switch, deprecated. The parameter, vnet, added.

Version 3.0.0

The parameter, l2-net, added.

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