FEATURE	DESCRIPTION
Multicast VLAN	Multicast VLAN Registration (MVR) is designed for applications
Registration (MVR)	(such as Media-on-Demand (MoD)) using multicast traffic
	across a network. MVR allows one single multicast VLAN to be
	shared among different subscriber VLANs on the network.
	This improves bandwidth utilization by reducing multicast
	traffic in the subscriber VLANs and simplifies multicast group
	management.
L2 Multicast	The device supports Layer-2 multicast switching with line-rate
	(wire speed) switching for all packet sizes and conditions. In
	addition, the MES-2110 can send packets to Ethernet devices
	that are not VLAN-aware by untagging (removing the VLAN
	tags) IP multicast packets.
STP (Spanning Tree	STP detects and breaks network loops and provides backup
Protocol)	links between switches, bridges or routers. It allows a MES-
	2110 to interact with other STP-compliant switches in your
	network to ensure that only one path exists between any two
	stations on the network.
Loop Detection	Use the loop detection feature to monitor any network loops on
	the edge of your network.
IP Source Guard	Use IP source guard to filter unauthorized DHCP and ARP
	packets in your network.
Link Aggregation	Link aggregation (trunking) is the grouping of physical ports
	into one logical higher-capacity link. You may want to trunk
	ports if for example, it is cheaper to use multiple lower-speed
	links than to under-utilize a high-speed, but more costly,
	single-port link.
Port Authentication and	For security, the MES-2110 allows authentication using IEEE
Security	802.1x with an external RADIUS server and port security that
	allows only packets with dynamically learned MAC addresses
	and/or configured static MAC addresses to pass through a port
	on the MES-2110.
Authentication and	The MES-2110 supports authentication and accounting services
Accounting	via RADIUS.
Device Management	Use the web configurator or commands to easily configure the
	rich range of features on the MES-2110.
Syslog	The MES-2110 can generate syslog messages for system
	monitoring.
Firmware Upgrade	Download new firmware (when available) from the ZyXEL web
	site and use the web configurator, CLI or TFTP tool to put it on
	the MES-2110.

	Note: Only upload firmware for your specific model!
Configuration Backup & Make a copy of the MES-2110’s configuration and put it back on
Restoration	the MES-2110 later if you decide you want to revert back to an
	earlier configuration.
