Time for entries in the “LAN” MAC Address Table is the same as the one set for
the “WAN” MAC Address Table. Any new entries will be added to the table even
if the respective bin is full because in such case the oldest entry in the bin will be
removed.
Each “LAN” switch port exposed on the paddleboard (i.e. customer access port)
has a configurable learning mode. A port in
No Blocking
mode will learn the
MACs of all connected devices (up to an optional user-configurable limit). A port
in
Secured
mode has the MAC learning disabled. It will let communicate only
those local devices whose MACs either appear in the user-defined list of the
port‟s static MACs or had been learned before the port got secured (pseudo-
static MACs). Both static and pseudo-static MACs are stored in flash to allow for
restoring normal operation after unit reboot. The user can have as many as 20
static MAC entries defined per port.
Note:
The “LAN” MAC Address Table‟s static and pseudo-static entries do not
age out. All entries in the “WAN” MAC Address table are subject to aging.
Note:
The same MAC address can have multiple instances in the MAC address
table as long as it appears on different D-PVLANs (or different QVLANs, if
QVLAN filtering is enabled).
CAUTION
If QVLAN filtering is used and there is a need to use the same MAC
address in two different D-PVLANs, these MAC addresses must be on
different QVLANs. Otherwise, traffic misrouting may appear. For
example, the MAC address A that appears on Port 1, D-PVLAN#1,
QVLAN#100 and the MAC address A that appears on Port 2, D-PVLAN#2,
QVLAN#100 will be the same entry in
the local “LAN” MAC address table.
Note
: If a device is moved from one ETHER-1000 site to another and stays on
the same D-PVLAN (and same QVLAN, if QVLAN filtering is enabled), its MAC
address entry will be updated with the new site information in the “WAN” MAC
Address Tables across the ETHER-1000 system as soon as the device becomes
active (regardless of the Aging Time settings).
Through the VistaNET software, the user can determine the MAC addresses
stored in the “LAN” MAC address table on per D-PVLAN basis. For any selected
D-PVLAN, a maximum of 138 MAC entries can be displayed. For each entry, it
is indicated whether it is a dynamic, static or pseudo-static entry and whether it
has been learned from a local port (in which case the port number is displayed)
or from a remote port. The entries are sorted in the ascending MAC address
order.
