Port Mirroring
Port Mirroring Overview
Port Mirroring copies all received and transmitted packets (including local traffic) from a source
port to a predefined destination port, in addition to the normal destination port of the packets.
Port Mirroring, also known as "sniffing" is useful in debugging network problems.
Port mirroring allows you to define a source port and a destination port, regardless of port type.
For example, a 10 Mbps and a 100 Mbps port can form a valid source/destination pair. You
cannot, however define the port mirroring source and destination ports as the same port.
You can define one source port and one destination port on each C360 stack for either received
- Rx - or transmitted and received - Tx + Rx - traffic.

Port Mirroring Implementation in the C360
Note the following limitations:
●
The VLAN binding parameters of the source and destination ports must be identical.
●
Ports which are members in a Link Aggregation Group (LAG) cannot also be used as Port
Mirroring Destination or Source ports.
●
On the stack level, port mirroring pairs can be configured between any Giga port, and
between any Giga port on the C360 and any 10/100Mbps port not residing on a C360.
