4-2 ALC1024 Overview
Your ALC1024 uses IEEE 802.1p Priority to assign priority levels to individual ports.
Fast Mode
The fast mode makes use of the “tag” subset of the IEEE 802.1Q standard to identify the source port of a frame
and speed traffic through a service gateway.
MAC (Media Access Control) Filtering
Use MAC filter commands to filter incoming frames based on MAC (Media Access Control) address(es) that you
specify. You may enable/disable specific ports. You may specify up to five MAC addresses per port.
Secured Host
Allow up to ten remote hosts to access your ALC1024 via IP addresses you specify.
System Error Logging
The system error log records error logs locally to the ALC1024 memory. These logs may be viewed again after a
warm restart.
UNIX Syslog Logging
Use UNIX syslog commands to send logs to your UNIX server.
Protocol
Multiple Protocols over AAL5 (RFC 1483)
Management
•
SNMP manageable
• Text-based management via telnet
Remote Firmware Upgrade
You can use FTP to perform configuration backup/restore and firmware upgrade for the ALC1024 from a remote
location.
Security
•
Password protection for system management
•
VLAN
IGMP Snooping
IGMP (Internet Group Management Protocol) snooping reduces multicast traffic for maximum performance.
Overheating Detection, Warning and Safegaurd
An ALM LED turns on when the ALC1024’s internal temperature is too high and turns off when the temperature
has returned to a normal level. Fans in the main chassis cool the unit.
