• Confirm Action. Send
• Violate Action. Drop
For more information, see Configure a DiffServ Policy on page 200.
9. On the Service Configuration page, select the check box next to interfaces g7 and g8 to
attach the policy to these interfaces, and then click the Apply button. (See
Configure the
DiffServ Service Interface on page 205.)
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 include 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
1000000
Kbps. Packets that violate the committed rate and burst size are dropped.
802.1X Access Control
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 you
might want 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 to provide a means of authenticating and authorizing devices attached to a
LAN port with point-to-point connection characteristics. If the authentication and authorization
process fails, access control prevents access to that port. In this context, a port is a single
point of attachment to the LAN, such as a port of a MAC bridge and an association 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
