EASURES
This switch supports many methods of segregating traffic for clients
attached to each of the data ports, and for ensuring that only authorized
clients gain access to the network. Port-based authentication using IEEE
802.1X is commonly used for these purposes. In addition to these method,
several other options of providing client security are described in this
chapter. These include port-based authentication, which can be configured
to allow network client access by specifying a fixed set of MAC addresses.
The addresses assigned to DHCP clients can also be carefully controlled
with IP Source Guard and DHCP Snooping commands.
Table 86: General Security Commands
Command Group Function
Port Security
*
* The priority of execution for these filtering commands is Port Security, Port
Authentication, Network Access, Web Authentication, Access Control Lists, DHCP
Snooping, and then IP Source Guard.
Configures secure addresses for a port
802.1X Port
Authentication *
Configures host authentication on specific ports using 802.1X
Network Access * Configures MAC authentication and dynamic VLAN assignment
Web Authentication * Configures Web authentication
Access Control Lists * Provides filtering for IP frames (based on address, protocol, TCP/
UDP port number or TCP control code) or non-IP frames (based on
MAC address or Ethernet type)
DHCPv4 Snooping * Filters untrusted DHCPv4 messages on unsecure ports by building
and maintaining a DHCPv4 snooping binding table
DHCPv6 Snooping * Filters untrusted DHCPv6 messages on unsecure ports by building
and maintaining a DHCPv6 snooping binding table
IPv4 Source Guard * Filters IP traffic on insecure ports for which the source address
cannot be identified via DHCPv4 snooping nor static source
bindings
IPv6 Source Guard * Filters IPv6 traffic on insecure ports for which the source address
cannot be identified via DHCPv6 snooping nor static source
bindings
ARP Inspection Validates the MAC-to-IP address bindings in ARP packets
DoS Protection Protects against Denial-of-Service attacks
Port-based Traffic
Segmentation
Configures traffic segmentation for different client sessions based
on specified downlink and uplink ports
