DHCP Snooping:
This feature enables the DHCP Snooping (MSM-6226 switch) to include
information about client when forwarding DHCP requests from a DHCP
client to a DHCP server via Trust Port. DHCP snooping can be configured
on LAN switches to harden the security on the LAN to only allow clients with
specific IP/MAC addresses to have access to the network. In short, DHCP
snooping ensures IP integrity on a Layer 2 switched domain.

QoS:
Support Quality of Service by the IEEE 802.1P standard. There are two
priority queue and packet transmission schedule using Weighted Round
Robin (WRR). User-defined weight classification of packet priority can be
based on either VLAN tag on packets or user-defined port priority.

Port Trunking:
Support static port trunking and port trunking with IEEE 802.3ad LACP.
Bandwidth Control:

SNMP/RMON:
SNMP agent and RMON MIB. In the device, SNMP agent is a client
software which is operating over SNMP protocol used to receive the
command from SNMP manager (server site) and echo the corresponded
data, i.e. MIB object. Besides, SNMP agent will actively issue TRAP
information when happened.

to establish the multicast groups to forward the multicast packet to the
member ports, and, in nature, avoid wasting the bandwidth while IP
multicast packets are running over the network.
