    Figure 6-2-1 From the list, we can find that common reasons include UDLD, bpduguard, port security and loop. The specific reason for err disable of the current interface can be viewed. The system will attempt to restore the interface which is set as err disable after a period of time, 300 seconds by default. However, if the source of err disable is not solved fundamentally, the interface will be set as err disable again after restoring.

LACP introduction Link aggregation control protocol (LACP) is designed to perform dynamic link aggregation and disaggregation. This protocol is based on IEEE802.3ad and adopts the combination of link aggregation control protocol data units (LACPDUs) and peer-to-peer enabled LACP ports.

    destination will be forwarded from a same port. And the messages to different destinations may be forwarded from different aggregation ports. Many workstations will connect with the switch which will connect a router through an aggregation port. The link aggregation used on the switch is based on the source load balancing to ensure that the switch can use the router bandwidth effectively and distribute the communication through the physical connection with the workstation.

Part 7: VLAN 7.1 VLAN This part is mainly about 802.1Q-VLAN VLAN introduction The traditional Ethernet is a broadcast network. All hosts are in the same broadcast domain and communicate with each other through hub or switch.

    The above settings may cause the following network problems ⚫ A large number of broadcast packets or unknown unicast packets may exist in the network, which will waste network resources. ⚫ A host will receive many messages that are not intended for the host itself, will will lead to serious potential security problems.

    If VLAN 2 is selected for VLAN, there is no member by default, so it can be set manually. As shown in the above figure, port 2-3 is added to the tagged member of VLAN 2, and port 4-5 is added to the untagged member of VLAN 2.

    7.1.4 Port Setting Configure the port mode, entrance detection function and TPID function. There are three VLAN modes: Acess, Trunk, Hybird Access: connect to terminal devices (such as PC, camera, set top box, etc.) and set PVID directly. Trunk: the port connected between switches. Generally it needs to set many VLANs to perform tagged. Hybrid: mixed mode.

  • Page 35: Part 8: Mac Address Table

    When setting PVID value, VLAN must be added before setting. Vlan2-7 has been added in Chapter 7.1.1, so you can set 5. But if the value is set as 9, the system will report an error and the setting will be unsuccessful. In normal conditions, the entrance detection filtering will not set, neither the TPID.

  • Page 36: Dynamic Address

    Classification and features of MAC address table entries. According to their own features and configuration methods, MAC address table entries can be divided into three categories: ⚫ Static MAC address table entry: also known as "permanent address", which is added and deleted manually by user and will not age with time.
  • Page 37 According to the actual condition, the administrator can add, modify or delete the entries in the MAC address forwarding table manually. He can delete all MAC address table entries related to a certain port, or choose to delete certain types of MAC address table entries, such as dynamic table entries and static table entries.

    message in which the destination address is this MAC. If the destination address received by this switch is the bound MAC address, this switch will only forward to this bound port. 2. After configuring the static MAC address, the address table entry that originally existed in the dynamic MAC is deleted. 8.3 MAC address filtering If the MAC address filtering table entry is set in this switch, if the message with this MAC address whether in source MAC or destination MAC, it will be discarded as long as the switch receives it.

    device may save many outdated MAC address table entries, thus exhaust the MAC address table resources, which will cause the device unable to update MAC address table according to the changes of the network. If the aging time configured by user is too short, the device may delete the effective MAC address table entries, which may cause the device to broadcast a large number of data packets and affect its operation performance.

    topology changes to related equipment. 9.1.3 Basic concept of STP (1) Root bridge: The tree network structure must have root, so STP introduces the concept of Root Bridge. There is only one root bridge in the whole network, and the root bridge will change with the network topology, so the root bridge is not fixed.

  • Page 42: Basic Principle Of Stp

    (4) Path cost Path cost is the reference value of STP protocol for link selection. STP calculates the path cost to select the stronger link and block the redundant link, so as to prune the network into a tree network structure without loop. 9.1.4 Basic principle of STP STP can determine the network topology by transmitting BPDU between devices.
