Mirroring - EverFocus ES2446-51 User Manual

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.

4.1.9 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.
