Description
Use the igmp transparent enable command to enable transparent IGMP message transmission on
the port.
Use the undo igmp transparent enable command to disable transparent IGMP message transmission
on the port.
By default, transparent IGMP message transmission is disabled on a port.
For a VLAN-VPN-disabled port, the switch can transmit an IGMP message received on the port within
the VLAN that the IGMP message belongs to normally. For the switch to transparently transmit an IGMP
message received on a VLAN-VPN port in the outer VLAN, however, you must enable transparent
IGMP message transmission on the port.
If your switch is required to process the IGMP messages received on a VLAN-VPN port (for
example, because IGMP or IGMP snooping is enabled on the port), you must disable transparent
IGMP message transmission on the port so that the switch can process the IGMP messages
normally.
Do not enable transparent IGMP message transmission on a port without VLAN-VPN enabled.
Examples
# Enable transparent IGMP message transmission on port Ethernet 1/0/1.
