The following table describes the labels in this screen.
Table 15 Switch Setup
LABEL DESCRIPTION
MAC Address
Learning
Aging Time
Enter a time from 10 to 10,000 seconds. This is how long all
dynamically learned MAC addresses remain in the MAC address table
before they age out (and must be relearned). Enter 0 to disable the
aging out of MAC addresses.
GARP Timer: Switches join VLANs by making a declaration. A
declaration is made by issuing a Join message using GARP.
Declarations are withdrawn by issuing a Leave message. A Leave All
message terminates all registrations. GARP timers set declaration
timeout values. Click here for more information on VLANs.
Join Timer Join Timer sets the duration of the Join Period timer for GVRP in
milliseconds. Each port has a Join Period timer. The allowed Join Time
range is between 100 and 65535 milliseconds; the default is 200
milliseconds.
Leave Timer Leave Timer sets the duration of the Leave Period timer for GVRP in
milliseconds. Each port has a single Leave Period timer. Leave Time
must be two times larger than Join Timer; the default is 600
milliseconds.
Leave All Timer Leave All Timer sets the duration of the Leave All Period timer for
GVRP in milliseconds. Each port has a single Leave All Period timer.
Leave All Timer must be larger than Leave Timer.
Port Isolation
Active
Turn on port isolation to block communications between subscriber
ports. When you enable port isolation you do not need to configure
the VLAN to isolate subscribers.
MAC Anti-
Spoofing Select this if you want the SAM1316-22 to generate an alarm and
issue a SNMP trap when an existing MAC address appears on another
port.
Switch Mode Select Standalone to use both of the SAM1316-22’s Ethernet ports
(ENET 1 and ENET 2) as uplink ports.
Note: Standalone mode is recommended for network topologies
that use loops.
Use Daisychain mode to cascade (daisychain) multiple SAM1316-22.
The SAM1316-22 uses Ethernet port one (ENET 1) as an uplink port
to connect to the Ethernet backbone and uses Ethernet port two
(ENET 2) to connect to another (daisychained or subtending)
SAM1316-22.
Note: Daisychain mode is recommended for network topologies
that do not use loops.
