802.1x
802.1X authentication: Provides access control on a per-client
or per-port basis:
• Client-level security that allows LAN access to 802.1X
clients (up to 32 per port) with valid user credentials
• Port-level security that allows LAN access only on ports on
which a single 802.1X-capable client (supplicant) has
entered valid RADIUS user credentials
Access Security Guide
acl
Access Control Lists (ACLs): Filter layer-3 IP traffic to or from
a host to block unwanted IP traffic, and block or limit other
protocol traffic such as TCP, UDP, IGMP, and ICMP. Access
control entries (ACEs) specify the filter criteria and an action
(permit or deny) to take on a packet if it meets the criteria.
Advanced Traffic Management Guide
addrmgr
Address Table Manager: Manages MAC addresses that the
switch has learned and are stored in the switch’s address
table.
Management and Configuration Guide
arp-protect
Dynamic ARP Protection: Protects the network from ARP
cache poisoning. Only valid ARP requests and responses are
relayed or used to update the local ARP cache. ARP packets
with invalid IP-to-MAC address bindings advertised in the
source protocol address and source physical address fields
are discarded.
Access Security Guide
auth
Authorization: A connected client must receive authorization
through web, AMC, RADIUS-based, -based, or
802.1X authentication before it can send traffic to the switch.
