Benefit
• Allows VLAN1 to be disabled on any individual VLAN trunk link.
• Terminal Access Controller Access Control System Plus (TACACS+)
and Remote Authentication Dial-In User Service (RADIUS)
authentication enable centralized control of switch administration
and management.
• Allows for 15 levels of switch management authorization, ranging
from read-only to full read/write capabilities.
• Allows dynamic, port-based security, providing user authentication.
• Permits an IP phone to access the voice VLAN irrespective of the
authorized or unauthorized state of the port.
• Provides security and isolation between switch ports, which helps
ensure that users cannot snoop on other users' traffic.
• Bidirectional data support on the Switched Port Analyzer (SPAN)
port allows Cisco Secure Intrusion Detection System (IDS) to take
action when an intruder is detected.
• Allows administrators to be notified of users added to or removed
from the network. Good for tracking location of users or stolen
laptops.
• Secures the access to an access or trunk port based on MAC
address. After a specific timeframe, the aging feature removes the
MAC address from the switch to allow another device to connect to
the same port.
• Ability to trust the QoS priority settings if an IP phone is present and
to disable the trust setting in the event that the IP phone is removed,
thereby preventing a malicious user from overriding prioritization
policies in the network.
• Provides multicast authentication by filtering out non-subscribers and
limits the number of concurrent multicast streams available per port.
• Using VLAN Membership Policy Server (VMPS) client functionality,
ports can be assigned to VLANs based on the MAC address
connected to the port or a user login (using the CiscoWorks User
Registration Tool).
