Netgear S3300-28X-PoE+ (GS728TXP) - ProSAFE S3300 Smart Switch Series 管理者ガイド

If the interface mode is VLAN ID or Dot1p, specify the VLAN ID or 802.1p priority value in 
the Value field. 

This field is valid only when VLAN ID or dot1p is selected as the interface mode. 

From the CoS Override Mode list, specify the CoS override mode for the selected ports:

Enabled. The port ignores the 802.1p priority value in the Ethernet frames it receives 
from connected devices.

Disabled. The port trusts the priority value in the received frame.

Click the Apply button.

The Generic Attribute Registration Protocol (GARP) is used to exchange information 
between GARP participants to register and deregister attribute values within a bridged LAN. 
When a GARP participant declares or withdraws a given attribute, the attribute value is 
recorded with the applicant state machine for that attribute, for the port from which the 
declaration or withdrawal was made. 

Registration occurs only on ports that receive the GARP PDU containing a declaration or 
withdrawal. 

Deregistration occurs only if all GARP participants connected to the same LAN segment 
as the port withdraw the declaration. 

GARP is part of the IEEE 802.1p extension to its 802.1D (spanning tree) specification. It 
includes: 

GARP Information Declaration (GID)—The part of GARP that generates data.

GARP Information Propagation (GIP)—The part of GARP that distributes data.
