Figure 5-67. Voice VLAN OUI Table.
Parameter description:
• Delete: Check to delete the entry. It will be deleted during the next save.
• Telephony OUI: A telephony OUI address is a globally unique identifier assigned to a vendor by IEEE. It must be 6 characters
long and the input format is "xx-xx-xx" (x is a hexadecimal digit).
• Description: The description of OUI address. Normally, it describes which vendor telephony device it belongs to. The allowed
string length is 0 to 32.
• Add New entry: Click to add a new entry in Voice VLAN OUI table. An empty row is added to the table, the Telephony OUI,
Description.
• Buttons:
Apply: Click to apply changes.
Reset: Click to undo any changes made locally and revert to previously saved values.
NOTE: All non-telephony MAC addresses in the Voice VLAN will be blocked for 10 seconds.
For example: When Pkts enter the port and you add a new OUI entry, this can enable the OUI to match current Pkts, and the
packet will be forwarded.
5.13 GARP
The Generic Attribute Registration Protocol (GARP) provides a generic framework in which devices in a bridged LAN, e.g. end
stations and switches, can register and de-register attribute values, such as VLAN Identifiers, with each other. The 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 is 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 via LLC Type 1 services, using the group MAC address and PDU format defined
for the GARP application.
