Netgear M4300-24X24F (XSM4348S) - Stackable Managed Switch with 48x10G including 24x10GBASE-T and 24xSFP+ Layer 3 Guia Do Programa

You can enable the switch to operate as a DHCP Layer 2 relay agent to relay DHCP requests 
from clients to a Layer 3 relay agent or server. The Circuit ID and Remote ID can be added to 
DHCP requests relayed from clients to a DHCP server. This information is included in DHCP 
Option 82, as specified in sections 3.1 and 3.2 of RFC3046.

This command enables the DHCP Layer 2 Relay agent for an interface a range of interfaces 
in, or all interfaces. The subsequent commands mentioned in this section can only be used 
when the DHCP L2 relay is enabled.

This command disables DHCP Layer 2 relay agent for an interface or range of interfaces.

This parameter sets the DHCP Option-82 Circuit ID for a VLAN. When enabled, the interface 
number is added as the Circuit ID in DHCP option 82.

VLAN ID

The VLAN in which the MAC Address is learned.

MAC Address

A unicast MAC address for which the switch has forwarding and or filtering information. As the data 

is gleaned from the MFDB, the address will be a multicast address. The format is 6 two-digit 
hexadecimal numbers that are separated by colons, for example 01:23:45:67:89:AB.

Type

The type of the entry. Static entries are those that are configured by the end user. Dynamic entries 
are added to the table as a result of a learning process or protocol.

Description

The text description of this multicast table entry. 

Interfaces

The list of interfaces that are designated for forwarding (Fwd:) and filtering (Flt:).
