XS712T Smart Switch
8. Configure the Policy attributes as follows:
• Assign Queue. 3
• Policy Attribute. Simple Policy
• Color Mode. Color Blind
• Committed Rate. 1000000 Kbps
• Committed Burst Size. 128 KB
• Confirm Action. Send
• Violate Action. Drop
For additional information about this screen, see Policy Configuration on page 166.
9. From the Service Configuration screen, select the check box next to interfaces g7 and g8 to
attach the policy to these interfaces, and then click Apply (see
Service Configuration on
page 169).
All UDP packet flows destined to the 192.12.2.0 network with an IP source address from the
192.12.1.0 network that have a Layer 4 Source port of 4567 and Destination port of 4568
from this switch on ports 7 and 8 are assigned to hardware queue 3.
On this network, traffic from streaming applications uses UDP port 4567 as the source and
4568 as the destination. This real-time traffic is time sensitive, so it is assigned to a
high-priority hardware queue. By default, data traffic uses hardware queue 0, which is
designated as a best-effort queue.
Also the confirmed action on this flow is to send the packets with a committed rate of
1,000,000
Kbps and burst size of 128 KB. Packets that violate the committed rate and burst
size are dropped.

Local Area Networks (LANs) are often deployed in environments that permit unauthorized
devices to be physically attached to the LAN infrastructure, or permit unauthorized users to
attempt to access the LAN through equipment already attached. In such environments, it can
be desirable to restrict access to the services offered by the LAN to those users and devices
that are permitted to use those services.
Port-based network access control makes use of the physical characteristics of LAN
infrastructures in order to provide a means of authenticating and authorizing devices attached
to a LAN port that has point-to-point connection characteristics and of preventing access to
that port in cases in which the authentication and authorization process fails. In this context, a
port is a single point of attachment to the LAN, such as ports of MAC bridges and
associations between stations or access points in IEEE 802.11 Wireless LANs.
The IEEE 802.11 standard describes an architectural framework within which authentication
and consequent actions take place. It also establishes the requirements for a protocol
between the authenticator (the system that passes an authentication request to the
authentication server) and the supplicant (the system that requests authentication), as well as
between the authenticator and the authentication server.
