Details
Security	IEEE 802.1x allows dynamic, port-based security, providing user authentication. IEEE 802.1x with VLAN assignment allows a dynamic VLAN assignment for a specific user regardless of where the user is connected. IEEE 802.1x with voice VLAN permits an IP phone to access the voice VLAN irrespective of the authorized or unauthorized state of the port. IEEE 802.1x and port security are provided to authenticate the port and manage network access for all MAC addresses, including that of the client. IEEE 802.1x with an ACL assignment allows for specific identity-based security policies regardless of where the user is connected. IEEE 802.1x with guest VLAN allows guests without 802.1x clients to have limited network access on the guest VLAN. CISCO security VLAN ACLs on all VLANs prevent unauthorized data flows from being bridged within VLANs. CISCO standard and extended IP security router ACLs define security policies on routed interfaces for control-plane and data-plane traffic. Port-based ACLs for Layer 2 interfaces allow security policies to be applied on individual switch ports. Secure Shell (SSH) Protocol, Kerberos, and Simple Network Management Protocol Version 3 (SNMPv3) provide network security by encrypting administrator traffic during Telnet and SNMP sessions. SSH Protocol, Kerberos, and the cryptographic version of SNMPv3 require a special cryptographic software image because of U.S. export restrictions. Private VLAN Edge provides security and isolation between switch ports, which helps ensure that users cannot snoop on other users' traffic. Dynamic ARP Inspection helps ensure user integrity by preventing malicious users from exploiting the insecure nature of the ARP protocol. DHCP Snooping prevents malicious users from spoofing a DHCP server and sending out bogus addresses. This feature is used by other primary security features to prevent a number of other attacks such as ARP poisoning.
