attributes are propagated to devices in the bridged LAN, and these devices form a
¡°reachability¡± tree that is a subset of an active topology. GARP defines the
architecture, rules of operation, state machines and variables for the registration and
de-registration of attribute values.
A GARP participation in a switch or an end station consists of a GARP application
component, and a GARP Information Declaration (GID) component associated with
each port or the switch. The propagation of information between GARP participants
for the same application in a bridge is carried out by the GARP Information
Propagation (GIP) component. Protocol exchanges take place between GARP
participants by means of LLC Type 1 services, using the group MAC address and PDU
format defined for the GARP application concerned.
2-29.1 Global Config
The switch stores its configuration in a number of text files in CLI format. The files are
either virtual (RAM-based) or stored in flash on the switch.
There are three system files:
Running-config: A virtual file that represents the currently active configuration
on the switch. This file is volatile.
Startup-config: The startup configuration for the switch, read at boot time.
Default-config: A read-only file with vendor-specific configuration. This file is
read when the system is restored to default settings.
It is also possible to store up to two other files and apply them to running-config,
thereby switching configuration.
Web Interface
To configure the GVRP in the web interface:
1. Click Configuration, GVRP, Global Config
