  • Page 22: Types Of Mac Address Table Entries

    The following is how an AP learns a MAC address when it receives a frame from a port, Port A for example: Check the source MAC address (MAC-SOURCE for example) of the frame. Assume that frames with the source MAC address MAC-SOURCE can be forwarded through Port A. Look up the MAC address table by the MAC address for a match and do the following: If an entry is found for the MAC address, update the entry.

  • Page 23: Configuring A Mac Address Table

    Unicast mode: If an entry is available for the destination MAC address, the AP forwards the frame directly from the hardware. Broadcast mode: If the AP receives a frame with the destination address being all Fs, or no entry is available for the destination MAC address, the AP broadcasts the frame to all the interfaces except the receiving interface.

  • Page 28 would occur in a loop network and prevents decreased performance of network devices caused by duplicate packets received. In the narrow sense, STP refers to IEEE 802.1d STP; in the broad sense, STP refers to the IEEE 802.1d STP and various enhanced spanning tree protocols derived from that protocol. Protocol packets of STP STP uses bridge protocol data units (BPDUs), also known as configuration messages, as its protocol packets.

  • Page 29: How Stp Works

    Figure 7-1 A schematic diagram of designated bridges and designated ports All the ports on the root bridge are designated ports. Path cost Path cost is a reference value used for link selection in STP. By calculating path costs, STP selects relatively robust links and blocks redundant links, and finally prunes the network into a loop-free tree.
  • Page 30 For simplicity, the descriptions and examples below involve only four fields of configuration BPDUs: Root bridge ID (represented by bridge priority) Root path cost (related to the rate of the link connecting the port) Designated bridge ID (represented by bridge priority) Designated port ID (represented by port name) Calculation process of the STP algorithm Initial state...
  • Page 31 Selection of the root port and designated ports on a non-root bridge The process of selecting the root port and designated ports is as follows: Table 7-3 Selection of the root port and designated ports Step Description A non-root bridge regards the port on which it received the optimum configuration BPDU as the root port.
  • Page 32 Initial state of each bridge The following table shows the initial state of each bridge. Table 7-4 Initial state of each bridge Bridge Port name BPDU of port {0, 0, 0, AP1} Device A {0, 0, 0, AP2} {1, 0, 1, BP1} Device B {1, 0, 1, BP2} {2, 0, 2, CP1}...
  • Page 33 BPDU of port after Bridge Comparison process comparison Port CP1 receives the configuration BPDU of Device A {0, 0, 0, AP2}. Device C finds that the received configuration BPDU is superior to the configuration BPDU of the local port {2, 0, 2, CP1}, and updates the configuration BPDU of CP1.
  • Page 34 Figure 7-3 The final calculated spanning tree Device A With priority 0 Device B With priority 1 Device C With priority 2 The spanning tree calculation process in this example is only a simplified process. The BPDU forwarding mechanism in STP Upon network initiation, every bridge regards itself as the root bridge, generates configuration BPDUs with itself as the root, and sends the configuration BPDUs at a regular hello interval.

  • Page 35: Introduction To Rstp

    For this reason, as a mechanism for state transition in STP, the newly elected root ports or designated ports require twice the forward delay time before transiting to the forwarding state to ensure that the new configuration BPDU has propagated throughout the network. Hello time is the time interval at which a bridge sends hello packets to the surrounding bridges to ensure that the paths are fault-free.
  • Page 36 MSTP supports mapping VLANs to MST instances (MSTIs) by means of a VLAN-to-MSTI mapping table. MSTP can reduce communication overheads and resource usage by mapping multiple VLANs to one MSTI. MSTP divides a switched network into multiple regions, each containing multiple spanning trees that are independent of one another.
  • Page 37 They are physically linked with one another. For example, all the bridges in region A0 in Figure 7-4 have the same MST region configuration: The same region name, The same VLAN-to-MSTI mapping configuration (VLAN 1 is mapped to MSTI 1, VLAN 2 to MSTI 2, and the rest to the common and internal spanning tree (CIST, that is, MSTI 0), and The same MSTP revision level (not shown in the figure).
  • Page 38 Boundary port A boundary port is a port that connects an MST region to another MST region, or to a single spanning-tree region running STP, or to a single spanning-tree region running RSTP. In Figure 7-4, for example, if a bridge in region A0 is interconnected with the first port of a bridge in region D0 and the common root bridge of the entire switched network is located in region A0, the first port of that bridge in region D0 is the boundary port of region D0.
  • Page 39 Figure 7-5 helps understand these concepts. In this figure: Bridges A, B, C, and D constitute an MST region. Port 1 and port 2 of bridge A connect to the common root bridge. Port 5 and port 6 of bridge C form a loop. Port 3 and port 4 of bridge D connect downstream to other MST regions.

  • Page 40: Protocols And Standards

    Within an MST region, MSTP generates different MSTIs for different VLANs based on the VLAN-to-instance mappings. MSTP performs a separate calculation process, which is similar to spanning tree calculation in STP, for each spanning tree. For details, refer to How STP works.

    When the root bridge of an instance fails or is shut down, the secondary root bridge (if you have specified one) can take over the role of the primary root bridge. However, if you specify a new primary root bridge for the instance then, the secondary root bridge will not become the root bridge. If you have specified multiple secondary root bridges for an instance, when the root bridge fails, MSTP will select the secondary root bridge with the lowest MAC address as the new root bridge.

  • Page 46 MSTP can detect link failures and automatically restore blocked redundant links to the forwarding state. A bridge on the CIST determines whether a configuration BPDU received by a port has expired according to the max age parameter. If yes, it starts a new spanning tree calculation process.

  • Page 47: Configuring The Timeout Factor

    The settings of hello time, forward delay and max age must meet the following formulae; otherwise, network instability will frequently occur. 2 × (forward delay – 1 second) ú max age Max age ú 2 × (hello time + 1 second) It is recommended that you specify the network diameter with the stp bridge-diameter command and let MSTP automatically calculate optimal settings of these three timers based on the network diameter.

  • Page 48: Configuring Ports As Edge Ports

    The higher the maximum port rate is, the more BPDUs will be sent within each hello time, and the more system resources will be used. By setting an appropriate maximum port rate, you can limit the rate at which the port sends BPDUs and prevent MSTP from using excessive network resources when the network becomes instable.
  • Page 49 Specifying a standard that the AP uses when calculating the default path cost You can specify a standard for the AP to use in automatic calculation for the default path cost. The AP supports the following standards: dot1d-1998: The AP calculates the default path cost for ports based on IEEE 802.1d-1998. dot1t: The AP calculates the default path cost for ports based on IEEE 802.1t.

  • Page 50: Configuring Port Priority

    If you change the standard that the AP uses in calculating the default path cost, the port path cost value set through the stp cost command will become invalid. After the path cost of a port is changed, MSTP will re-calculate the role of the port and initiate a state transition.

  • Page 51: Configuring The Link Type Of Ports

    When the priority of a port is changed, MSTP will re-calculate the role of the port and initiate a state transition. Generally, a lower priority value indicates a higher priority. If you configure the same priority value for all the ports on a bridge, the priority of a port depends on the index number of the port. Changing the priority of a port triggers a new spanning tree calculation process.

  • Page 52: Enabling Mstp

    By default, the packet format recognition mode of a port is auto, namely the port automatically distinguishes the two MSTP packet formats, and determines the format of packets it will send based on the recognized format. You can configure the MSTP packet format on a port. After the configuration, when working in MSTP mode, the port sends and receives only MSTP packets of the format you have configured to communicate with bridges that send packets of the same format.

  • Page 53: Performing Mcheck

    To do... Use the command... Remarks Optional Enable MSTP for the ports stp enable By default, MSTP is enabled for all ports after it is enabled for the AP globally. To control MSTP flexibly, you can use the undo stp enable command to disable MSTP for certain ports so that they will not take part in spanning tree calculation and thus to save the CPU resources of the AP.

  • Page 54: Configuring Digest Snooping

    An mCheck operation takes effect on a bridge only when MSTP operates in RSTP or MSTP mode. Configuring Digest Snooping As defined in IEEE 802.1s, connected bridges are in the same region only when the MST region-related configurations (domain name, revision level, VLAN-to-instance mappings) on them are identical. An MSTP bridge identifies bridges in the same MST region by checking the configuration ID in configuration BPDUs.
  • Page 55 With Digest Snooping enabled, comparison of configuration digest is no longer performed for in-the-same-region check, so the VLAN-to-instance mappings must be the same on associated ports. With global Digest Snooping enabled, modification of VLAN-to-instance mappings and removing of the current region configuration with the undo stp region-configuration command are not allowed.

  • Page 56: Configuring No Agreement Check

    [AP B-Ethernet1/0/1] stp config-digest-snooping [AP B-Ethernet1/0/1] quit [AP B] stp config-digest-snooping Configuring No Agreement Check In RSTP and MSTP, two types of messages are used for rapid state transition on designated ports: Proposal: sent by designated ports to request rapid transition Agreement: used to acknowledge rapid transition requests Both RSTP and MSTP bridges can perform rapid transition on a designated port only when the port receives an agreement packet from the downstream bridge.
  • Page 57 If the upstream bridge is a third-party device, the rapid state transition implementation may be limited. For example, when the upstream bridge uses a rapid transition mechanism similar to that of RSTP, and the downstream bridge adopts MSTP and does not work in RSTP mode, the root port on the downstream bridge receives no agreement packet from the upstream bridge and thus sends no agreement packets to the upstream bridge.

  • Page 58: Configuring Protection Functions

    Configuring Protection Functions An MSTP bridge supports the following protection functions: BPDU guard Root guard Loop guard TC-BPDU guard Among loop guard, root guard and edge port settings, only one function can take effect on the same port at the same time. Configuration prerequisites MSTP has been correctly configured on the AP.
  • Page 59 Enabling root guard The root bridge and secondary root bridge of a spanning tree should be located in the same MST region. Especially for the CIST, the root bridge and secondary root bridge are generally put in a high-bandwidth core region during network design. However, due to possible configuration errors or malicious attacks in the network, the legal root bridge may receive a configuration BPDU with a higher priority.
