z Packets with the destination MAC address matching the specified MAC address.
Compared with port mirroring, MAC-based mirroring is more precise and it can be used to
monitor packets of specific device in the network.
VLAN-Based Mirroring
With VLAN-based mirroring configured, a device mirrors packets received on all ports in
the specified VLAN to the destination port.
Compared with port mirroring, VLAN-based mirroring is more extensive and it can be used
to monitor packets of a specific VLAN or VLANs in the network.
Traffic Mirroring
Traffic mirroring uses ACL to monitor traffic that matches certain criteria on a specific port.
Unlike port mirroring where all inbound/outbound traffic passing through a port is
monitored, traffic mirroring provides a finer monitoring granularity. For detailed
configuration about traffic mirroring, refer to QoS-QoS Profile Operation.
Mirroring Configuration
Complete the following tasks to configure mirroring:
Task Remarks
Configuring Local Port Mirroring Optional
Configuring Remote Port Mirroring Optional
Configuring MAC-Based Mirroring Optional
Configuring VLAN-Based Mirroring Optional
On an S5100 series Ethernet switch, only one destination port for local port mirroring or
one reflector port for remote port mirroring can be configured, and the two kinds of ports
cannot both exist.
Configuring Local Port Mirroring
Configuration prerequisites
z The source port is determined and the direction in which the packets are to be mirrored
is determined.
z The destination port is determined.
