  • Page 144: Qos Overview

    The priorities are 0 to 7, with 0 the lowest priority and 7 the highest. When a tagged packet is received on a port on the switch, it is examined by the AT-S79 software for its priority. The switch software uses the priority to determine which egress priority queue the packet should be stored in on the egress port.

  • Page 145: Table 2. Default Mappings Of Ieee 802.1P Priority Levels To Egress Port Priority Queues

    Note QoS is disabled by default on the switch. You can customize these priority-to-queue assignments using the AT-S79 management software. The procedure for changing the default mappings is found in “Mapping CoS Priorities to Egress Queues” on page 147. Note that because all ports must use the same priority-to-egress queue mappings, these mappings are applied at the switch level.
  • Page 146 Chapter 12: Quality of Service (QoS) One last thing to note is that CoS does not change the priority level in a tagged packet. The packet leaves the switch with the same priority it had when it entered. This is true even if you change the default priority-to- egress queue mappings.

With this feature, the switch will not allow an end node to send or receive traffic through a port until the user of the node logs on by entering a username and password.

    AT-S79 Management Software User’s Guide Authentication Below is a brief overview of the authentication process that occurs between a supplicant, authenticator, and authentication server. For further Process details, refer to the IEEE 802.1x standard. Either the authenticator (that is, a switch port) or the supplicant can initiate an authentication prompt exchange.

    Chapter 17: 802.1x Port-based Network Access Control server. Each client that attempts to access the network is uniquely identified by the switch using the client's MAC address. Force-unauthorized - Places the port in the unauthorized state, ignoring all attempts by the client to authenticate. This port control setting blocks all users from accessing the network through the port and is similar to disabling a port and can be used to secure a port from use.

This can introduce security risks and can result in undesirable switch behavior. To avoid this, Allied Telesis recommends use the Force- authorized setting of the Port Control feature on ports that are connected to more than one end node, such as a port connected to another switch or to a hub.
