    VLAN configuration Introduction to VLAN Ethernet is a network technology based on the Carrier Sense Multiple Access/Collision Detect (CSMA/CD) mechanism. As the medium is shared, collisions and excessive broadcasts are common on Ethernet networks. To address the issue, virtual LAN (VLAN) was introduced to break a LAN down into separate VLANs.

    MSTP STP and RSTP limitations STP does not support rapid state transition of ports. A newly elected port must wait twice the forward delay time before transiting to the forwarding state, even if it connects to a point-to-point link or is an edge port. Although RSTP supports rapid network convergence, it has the same drawback as STP—All bridges within a LAN share the same spanning tree, so redundant links cannot be blocked based on VLAN, and the packets of all VLANs are forwarded along the same spanning tree.

CDP-compatible LLDP operates in one of the following modes: TxRx: CDP packets can be transmitted and received.

    When the half lease duration elapses, the DHCP client sends to the DHCP server a DHCP-REQUEST unicast to extend the lease duration. Upon availability of the IP address, the DHCP server returns a DHCP-ACK unicast confirming that the client’s lease duration has been extended, or a DHCP-NAK unicast denying the request.

    Table 100 The network access device relays the Identity EAP-Response packet in a RADIUS Access-Request packet to the authentication server. Table 101 The authentication server uses the identity information in the RADIUS Access-Request to search its user database. If a matching entry is found, the server uses a randomly generated challenge (EAP-Request/MD5 challenge) to encrypt the password in the entry, and sends the challenge in a RADIUS Access-Challenge packet to the network access device.

It can protect networks against unauthorized access and is often used in network environments where both high security and remote user access are required.

    to prevent user passwords from being intercepted on insecure networks, RADIUS encrypts passwords before transmitting them. A RADIUS server supports multiple user authentication methods. Moreover, a RADIUS server can act as the client of another AAA server to provide authentication proxy services. Basic message exchange process of RADIUS illustrates the interaction of the host, the RADIUS client, and the RADIUS server.

PKI employs digital certificates, which are bindings of certificate owner identity information and public keys. It allows users to obtain certificates, use certificates, and revoke certificates.

    PKI architecture Entity An entity is an end user of PKI products or services, such as a person, an organization, a device like a router or a switch, or a process running on a computer. A certificate authority (CA) is a trusted authority responsible for issuing and managing digital certificates. A CA issues certificates, specifies the validity periods of certificates, and revokes certificates as needed by publishing CRLs.

    ACL configuration ACL overview With the growth of network scale and network traffic, network security and bandwidth allocation become more and more critical to network management. Packet filtering can be used to efficiently prevent illegal access to networks and to control network traffic and save network resources. One way to implement packet filtering is to use access control lists (ACLs).

    QoS configuration Introduction to QoS Quality of Service (QoS) reflects the ability of a network to meet customer needs. In an Internet, QoS evaluates the ability of the network to forward packets of different services. The evaluation can be based on different criteria because the network may provide various services. Generally, QoS performance is measured with respect to bandwidth, delay, jitter, and packet loss ratio during packet forwarding process.

  • Page 435

    Traffic congestion causes The traffic enters a device from a high speed link and is forwarded over a low speed link.   The packet flows enter a device from several incoming interfaces and are forwarded out an outgoing interface, whose rate is smaller than the total rate of these incoming interfaces. When traffic arrives at the line speed, a bottleneck is created at the outgoing interface causing congestion.

    Schematic diagram for SP queuing A typical switch provides eight queues per port. As shown in a, SP queuing classifies eight queues on a port into eight classes, numbered 7 to 0 in descending priority order. SP queuing schedules the eight queues strictly according to the descending order of priority. It sends packets in the queue with the highest priority first.

    queue. On a 100 Mbps port, you can set the weight values of WRR queuing to 50, 30, 10, 10, 50, 30, 10, and 10 (corresponding to w7, w6, w5, w4, w3, w2, w1, and w0 respectively). In this way, the queue with the lowest priority is assured of at least 5 Mbps of bandwidth, avoiding the disadvantage of SP queuing that packets in low-priority queues may fail to be served for a long time.
