Multicast VLAN
Registration (MVR) Multicast VLAN Registration (MVR) is designed for applications
(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
Protocol) STP detects and breaks network loops and provides backup
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
Security For security, the MES-2110 allows authentication using IEEE
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
Accounting The MES-2110 supports authentication and accounting services
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 &
Restoration Make a copy of the MES-2110’s configuration and put it back on
the MES-2110 later if you decide you want to revert back to an
earl
i er configuration.
