IGMP Configuration
IGMP Enabled: When enabled, the switch will monitor network traffic to
determine which hosts want to receive multicast traffic.
Router Ports: Set if ports are connecting to the IGMP administrative routers.
Unregistered IPMC Flooding enabled: Set the forwarding mode for
unregistered (not-joined) IP multicast traffic. The traffic will flood when
enabled, and forward to router-ports only when disabled.
IGMP Snooping Enabled: When enabled, the port will monitor network
traffic to determine which hosts want to receive the multicast traffic.
IGMP Querying Enabled: When enabled, the port can serve as the Querier,
which is responsible for asking hosts if they want to receive multicast traffic.
Mirroring
Port Mirroring is used on a network switch to send a copy of network packets
seen on one switch port (or an entire VLAN) to a network monitoring
connection on another switch port. This is commonly used for network
appliances that require monitoring of network traffic, such as an
intrusion-detection system.
Mirroring Configuration
Port to Mirror to: The port that will "duplicate" or "mirror" the traffic on the
source port. Only incoming packets can be mirrored. Packets will be
dropped when the available egress bandwidth is less than ingress
bandwidth.
Ports to Mirror: Select the ports that you want to mirror from this section of
the page. A port will be mirrored when the "Mirroring Enabled" check-box is
checked.
