Cisco Catalyst Blade Switch 3020 for HP Software Configuration Guide
OL-8915-03
Chapter 1 Overview
Features
•
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 on 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 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 directions
on routed interfaces (router ACLs) and VLANs and inbound on Layer 2 interfaces (port ACLs)
•
Extended MAC access control lists for defining security policies in the inbound direction on Layer 2
interfaces
•
VLAN ACLs (VLAN maps) for providing intra-VLAN security by filtering traffic based on
information in the MAC, IP, and TCP/UDP headers
•
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
•
IEEE 802.1Q tunneling so that customers with users at remote sites across a service-provider
network can keep VLANs segregated from other customers and Layer 2 protocol tunneling to ensure
that the customer’s network has complete STP, CDP, and VTP information about all users
•
Layer 2 point-to-point tunneling to facilitate the automatic creation of EtherChannels
•
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:
–
VLAN assignment for restricting IEEE 802.1x-authenticated users to a specified VLAN
–
Port security for controlling access to IEEE 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
–
Guest VLAN to provide limited services to non-IEEE 802.1x-compliant users
–
Restricted VLAN to provide limited services to users who are IEEE 802.1x compliant, but do
not have the credentials to authenticate via the standard IEEE 802.1x processes
–
IEEE 802.1x accounting to track network usage
–
IEEE 802.1x with wake-on-LAN to allow dormant PCs to be powered on based on the receipt
of a specific Ethernet frame
–
IEEE 802.1x readiness check to determine the readiness of connected end hosts before
configuring IEEE 802.1x on the switch
•
MAC authentication bypass to authorize clients based on the client MAC address
•
Network Admission Control (NAC) features:
