Cisco IE 3010 Switch Software Configuration Guide
OL-23145-01
Chapter 1 Overview
Features
• Local web authentication banner so that a custom banner or an image file can be displ ayed at a web
authentication login screen
• MAC authentication bypass (MAB) aging timer to detect inactive hosts that have authenticated after
they have authenticated by using MAB
• Password-protected access (read-only and read-write access) to management interfaces (device
manager, and the CLI) for protection against unauthorized configuration changes
• Multilevel security for a choice of security level, notification, and resulting actions
• Static MAC addressing for ensuring security
• Protected port option for restricting the forwarding of traffic to designated ports o n the same switch
• Port security option for limiting and identifying MAC addresses of the stations allowed to access
the port
• VLAN aware port security option to shut down the VLAN on the port when a violation occurs,
instead of shutting down the entire port.
• Port security aging to set the aging time for secure addresses on a port
• BPDU guard for shutting down a Port Fast-configured port when an invalid configuration occurs
• Standard and extended IP access control lists (ACLs) for defining security policies in both direct ions
on routed interfaces (router ACLs) and VLANs and inbound on La yer 2 interfaces (port ACLs)
• Extended MAC access control lists for defining security policies in the inbound direction on Layer 2
interfaces
• Source and destination MAC-based ACLs for filtering non-IP traffic
• DHCP snooping to filter untrusted DHCP messages between untrusted hosts and DHCP servers
• IP source guard to restrict traffic on nonrouted interfaces by filtering traffic based on the DHCP
snooping database and IP source bindings
• Dynamic ARP inspection to prevent malicious attacks on the switch by not relaying invalid ARP
requests and responses to other ports in the same VLAN
• Layer 2 protocol tunneling bypass feature to provide interoperability with third-party vendors
• IEEE 802.1x port-based authentication to prevent unauthorized devices (clients) from gaining
access to the network. These features are supported:
–
Multidomain authentication (MDA) to allow both a data device and a voice device, such as an
IP phone (Cisco or non-Cisco), to independently authenticate on the same IEEE 802.1x-enabled
switch port
–
Dynamic voice virtual LAN (VLAN) for MDA to allow a dynamic voice VLAN on an
MDA-enabled port
–
VLAN assignment for restricting 802.1x-authenticated users to a specified VLAN
–
Port security for controlling access to 802.1x ports
–
Voice VLAN to permit a Cisco IP Phone to access the voice VLAN regardless of the authorized
or unauthorized state of the port
–
IP phone detection enhancement to detect and recognize a Cisco IP phone.
–
Guest VLAN to provide limited services to non-802.1x-compliant users
–
Restricted VLAN to provide limited services to users who are 802.1x compliant, but do not have
the credentials to authenticate via the standard 802.1x processes
–
802.1x accounting to track network usage
