IPv4 Access Control Lists (ACLs)
Introduction
Optional PCM and IDM Applications
ProCurve Manager is a Windows-based network management solution for all
manageable ProCurve devices. It provides network mapping and polling
capabilities, device auto-discovery and topology, tools for device configura-
tion and management, monitoring network traffic, and alerts and trouble-
shooting information for ProCurve networks.
ProCurve Identity Driven Manager (IDM) is an add-on module to the ProCurve
Manager plus (PCM+) application. IDM extends the functionality of PCM+ to
include authorization control features for edge devices in networks using
RADIUS servers and Web-Authentication, MAC-Authentication, or 802.1X
security protocols.
For more information, including electronic copies of the PCM and IDM
manuals, visit the ProCurve Web site at www.procurve.com. (The PCM and IDM
documentation is available under Network Management on the Product manuals
page of the Technical Support area.)
General Application Options
Layer 3 IP filtering with Access Control Lists (ACLs) enables you to improve
network performance and restrict network use by creating policies for:
â– Switch Management Access: Permits or denies in-band manage-
ment access. This includes preventing the use of certain TCP or UDP
applications (such as Telnet, SSH, web browser, and SNMP) for
transactions between specific source and destination IP addresses.
â– Application Access Security: Eliminates inbound, unwanted IP,
TCP, or UDP traffic by filtering packets where they enter the switch
on specific physical ports or trunks.
This chapter describes how to configure, apply, and edit ACLs, and how to
monitor the results of ACL actions.
Notes ACLs can enhance network security by blocking selected IP traffic, and can
serve as one aspect of maintaining network security. However, because ACLs
do not provide user or device authentication, or protection from malicious
manipulation of data carried in IP packet transmissions, they should not
be relied upon for a complete security solution.
ACLs do not screen non-IP traffic such as AppleTalk and IPX.
