The Dynamic Address Table contains the MAC addresses
learned by monitoring the source address for traffic
entering the switch. When the destination address for
inbound traffic is found in the database, the packets
intended for that address are forwarded directly to the
associated port. Otherwise, the traffic is flooded to all
ports.
Admin > Dynamic Address
The
Dynamic Address
screen contains parameters for
querying information in the Dynamic MAC Address Table,
including the interface type, MAC addresses, VLAN, and
table storing. The Dynamic MAC Address table contains
information about the aging time before a dynamic MAC
address is erased, and includes parameters for querying
and viewing the Dynamic MAC Address table. The Dynamic
MAC Address table contains address parameters by which
packets are directly forwarded to the ports. The Dynamic
Address Table can be sorted by interface, VLAN, and MAC
Address.
Address Aging
Specifies the amount of time (in seconds)
the MAC address remains in the Dynamic MAC Address
table before it times out, if no traffic from the source is
detected. The default value is 300 seconds.

reporting messages are assigned a severity code, and
include a message mnemonic, which identifies the source
application generating the message. It allows messages
to be filtered based on their urgency or relevancy. Each

Admin > Port Mirroring
Admin > Port Mirroring
Port mirroring monitors and mirrors network traffic by
forwarding copies of incoming and outgoing packets
from one port to a monitoring port. Port mirroring can be
used as diagnostic tool and/or a debugging feature. Port
mirroring also enables switch performance monitoring.
Network administrators configure port mirroring by
selecting a specific port to copy all packets, and different
ports from which the packets are copied.
Source Port
Defines the port to which traffic is mirrored.
Type
Indicates the port mode configuration for port
mirroring. The possible field values are:
RxOnly
•
Defines the port mirroring on receiving ports.
This is the default value.
TxOnly

Defines the port mirroring on both receiving and
transmitting ports.
Target Port
Defines the port from which traffic is
mirrored.
Admin > Cable Test
The

Cable Length test.
Admin > Cable Test
Port
This is the port to which the cable is connected.
Test Result
This is the test result. OK indicates that the
cable passed the test. No Cable means there is no cable
connected to the port. Open Cable means the cable is
