Mirroring - EverFocus ES1645-51 User Manual

 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.

4.7 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.
