All the QoS Needed in the Wiring Closet for
Today’s Voice and Data Networking
» Eight priority assigned to four queues
»IEEE 802.1p for Layer 2 QoS
»DSCP (DiffServ) for Layer 3 QoS
Key Features
»IEEE 802.1p to DSCP remarking traffic ready for
transport to the Layer 3 core of the network
» Layer 2 and Layer 3 Access Control List (ACL)
Securing the Network at its
Most Vulnerable Point
»IEEE 802.1x and RADIUS network login: for advanced
control for user authentication and accountability
»Guest VLAN: to ensure visitors or unauthorized
users only connect to services defined by IT such as Internet services

» TACACS+: for ease of management security
administration
» Layer 2 and Layer 3 Access Control List (ACL)
» Port MAC address security options

Access Control Lists (ACLs)
» Access Control Lists enable inspection of incoming
frames and classify them based on various criteria.
Specific actions can then be applied to these frames
in order to more effectively manage the network
traffic. Typically ACLs are used as a security
mechanism, either permitting or denying entry (hence
the name Access Control) for frames in a group, but
ACLs can also be applied to QoS.
Supported ACL types are:
- IP ACLs: applicable to IP packet type. All
classification fields are related to IP packets.
- MAC ACLs: classification fields are based on Layer
2 fields.
