attempt is made to add an entry after it is full. The event log is preserved across system
resets.

Mirroring
The Port Mirroring screen allows you to view and configure port mirroring on the system.
Port mirroring selects the network traffic for analysis by a network analyzer. This is done for
specific ports of the switch. As such, many switch ports are configured as source ports, and
one switch port is configured as a destination port. You can configure how traffic is mirrored
on a source port. Packets that are received on the source port, that are transmitted on a port,
or are both received and transmitted, can be mirrored to the destination port.

one switch port is configured as a destination port. You can configure how traffic is mirrored
on a source port. Packets that are received on the source port, that are transmitted on a port,
or are both received and transmitted, can be mirrored to the destination port.
The packet that is copied to the destination port is in the same format as the original packet
on the wire. This means that if the mirror is copying a received packet, the copied packet is
VLAN tagged or untagged as it was received on the source port. If the mirror is copying a
transmitted packet, the copied packet is VLAN tagged or untagged as it is being transmitted
on the source port.
