FIELD DESCRIPTION EXAMPLE
Bridge Max
Age(sec) 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)
Forward
Delay(sec) 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)
When you have completed this menu, press [ENTER] at the prompt “Press ENTER to Confirm…” to save your
configuration, or press [ESC] at any time to cancel.
Bridge Priority determines the root bridge, which in turn determines Bridge Hello Time, Max Age and Forwarding
Delay.
15.2.2 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Declarations are withdrawn by issuing a Leave message.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.

FIELD DESCRIPTION EXAMPLE
Join Timer
(msec) 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.
