DES-1228/ME Metro Ethernet Managed Switch CLI Reference Guide
Used to display the current IGMP Access Control configuration.
show igmp access_authentication ports [all | <portlist>]
This command is used to display the current IGMP Access Control
configuration.
<portlist> − specifies a range of ports to be displayed.
None.
Used to display the switch's current IGMP snooping forwarding table.
show igmp_snooping forwarding {[vlan <vlan_name 32> | vlanid
<vlanid_list>]}
This command displays the switch's current IGMP snooping
forwarding table. It provides an easy way for users to check the list of
ports that the multicast group that comes from a specific source will
be forwarded to. The packet comes from the source VLAN. They will
be forwarded to the forwarding VLAN. The IGMP snooping further
restricts the forwarding ports.
vlan − Specify the name of the VLAN for which you want to view
IGMP snooping forwarding table information.
vlanid - Specify the ID of the VLAN for which you want to view IGMP
snooping forwarding table information. If no parameter is specified,
the system will display all current IGMP snooping forwarding table
entries of the switch.
None.
