ZyXEL Communications IES-1248 VDSL-SWITCH User Manual page 29

The IES-1248 allows you to use different channels (also called Permanent Virtual Circuits or PVCs) for different
services or subscribers. Define channels
each channel a priority. ATM Quality of Service (QoS) allows you to regulate the average rate and fluctuations of
data transmission. This helps eliminate congestion to allow the transmission of real time data (such as audio and
video).
IEEE 802.1x Port-based Authentication
The IES-1248 supports the IEEE 802.1x standard for centralized user authentication and accounting management
through an optional network authentication (RADIUS) server.
Management
•
Remote configuration backup/restore and firmware upgrade
•
SNMP manageable
• Text-based management locally via console port and remotely via telnet

Security
Password protection for system management
VLAN
MAC (Media Access Control) Count Filter
You can limit the number of MAC addresses that may be dynamically learned on a port. You may enable/disable
the MAC count filter on individual ports.
Static Multicast Filter
Use the static multicast filter to allow incoming frames based on multicast MAC address(es) that you specify. This
feature can be used in conjunction with IGMP snooping to allow multicast MAC address(es) that are not learned by
IGMP snooping.
IGMP Snooping
With IGMP snooping, group multicast traffic is only forwarded to ports that are members of that group. IGMP
Snooping generates no additional network traffic, allowing you to significantly reduce multicast traffic passing
through your IES-1248.
System Monitoring
•
System status (link status, rates, statistics counters)
•
Temperatures, voltage reports and alarms.
System Error Logging
