ALC1024 Overview
IEEE 802.1p Priority
The line card can add IEEE 802.1p Priority tags to non priority-tagged traffic that comes in through a subscriber
port. Other IEEE 802.1p aware devices in the Ethernet network can use the tags to prioritize the traffic. The line
card itself does not apply priority-based traffic scheduling for either upstream or downstream traffic.
Multiple PVCs
The line card allows you to use different channels (also called Permanent Virtual Circuits or PVCs) for different
services or subscribers. Define channels
1
on each DSL port for different services.
IEEE 802.1x Port-based Authentication
The line card supports the IEEE 802.1x standard for centralized user authentication and accounting management
through an optional network authentication (RADIUS) server.
Protocol
Multiple Protocols over AAL5 (RFC 1483)
MAC (Media Access Control) Filter
Use the MAC filter to filter incoming frames based on MAC (Media Access Control) address(es) that you specify.
You may enable/disable the MAC filter on specific ports. You may specify up to ten MAC addresses per port.
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
IGMP (Internet Group Management Protocol) snooping reduces multicast traffic for maximum performance.
System Monitoring
System status (link status, rates, statistics counters)
Temperatures, voltage reports and alarms.
Overheating Detection, Warning and Safegaurd
The
ALM
LED turns on when the line card’s internal temperature is too high and turns off when the temperature
has returned to a normal level.
1
Up to eight channels on each DSL port at the time of writing.
