FIELD DESCRIPTION EXAMPLE
Max Age This is the maximum time (in seconds) a device waits without receiving a BPDU
before attempting to reconfigure. All device ports (except for designated ports)
should receive BPDUs at regular intervals. Any port that ages out STP
information (provided in the last BPDU) becomes the designated port for the
attached LAN. If it is a root port, a new root port is selected from among the
device ports attached to the network. The allowed range is 6 to 40 seconds.
20 (default)
Forwarding
Delay
This is the maximum time (in seconds) a device waits before changing states.
This delay is required because every device must receive information about
topology changes before it starts to forward frames. In addition, each port needs
time to listen for conflicting information that would make it return to a blocking
state; otherwise, temporary data loops might result. The allowed range is 4 to 30
seconds.
15 (default)
Bridge Priority determines the root bridge, which in turn determines Hello Time, Max Age and
Forwarding Delay.
4.2.4 GARP Timer Setup
GARP (Generic Attribute Registration Protocol) allows network devices to register and de-register attribute values
with other GARP participants within a bridged LAN. GARP is a protocol that provides a generic mechanism for
protocols that serve a more specific application, for example, GVRP (GARP VLAN Registration Protocol).
GARP and GVRP are the protocols used to automatically register VLAN membership across switches.
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Declarations are withdrawn by issuing a Leave message.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.
Select Yes in the Edit GARP Timer field in menu 2 to go to Menu 2.2 — GARP Timer Setup.

FIELD DESCRIPTION EXAMPLE
Join Timer Join Timer sets the duration of the Join Period timer for GARP 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.
200 (default)
Leave Timer Leave Timer sets the duration of the Leave Period timer for GARP in
milliseconds. Each
ort has a sin
le Leave Period timer. Leave Time
must be
600 (default)
Menu 2.2 - GARP Timer Setup
Join Timer(Timer (msec)= 200
Leave Timer(Timer (msec)= 600
Leave All Timer(Timer (msec)= 10000
Press ENTER to Confirm or ESC to Cancel:
The Range of Join Timer is between 100 and 65535.
