Deploying VLANs in Batches

This topic describes how to quickly deploy VLANs to devices and ports in batches during network deployment.

Scenario

The switch in a company connects many users and users with the same service requests access the network using different devices. To ensure communication security and avoid broadcast storms, the administrator wants to enable mutual access for users with the same service requests and to disable mutual access for users with different service requests. The administrator can create VLANs based on ports and assign ports for users with the same service requests to the same VLAN. In this case, users that belong to different VLANs cannot communicate with each other while users from the same VLAN can communicate with each other.

Deploying Enterprise Voice VLANs

Two data flows, including voice data and non-voice data, exist on the network. Voice data has higher priority than non-voice data during transmission, which reduces the delay and packet loss phenomena that may arise from the transmission. This topic describes how to quickly deploy voice VLANs.

Scenario

A company has purchased IP phones. To ensure communication quality for office calls and telephone conferences, voice data is transmitted through VLAN 7 and non-voice data is transmitted through VLAN 8. The MAC address and mask for one IP phone are 60-30-40-50-60-70 and E0-00-00-00-00-00 respectively.

Locating VLAN Path Faults Using the Terminal Access Component and VLAN Topology

It consumes time and energy to manually locate network connectivity faults arising from VLAN deployment errors. This topic describes how to quickly locate faults arising from VLAN deployment errors.

Scenario

In a data center, server Device2 whose MAC address is 00-15-5D-3A-DF-08 is disconnected from the network. Maintenance personnel search for terminal access records based on the server MAC address and find out the switch and port connected to the server. Maintenance personnel check devices and links along the VLAN path and quickly locate the fault.

Networking Diagram

Figure 12-12 shows the networking diagram.

Figure 12-12 Network planning of an enterprise
Prerequisites
  • Devices have been added to eSight.
  • SNMP and Telnet parameters have been set as planned on devices and eSight.
Configuration Roadmap
  1. Search for terminal access records based on the server MAC address and find out the switch and port connected to the server. Click Locate in Panel to verify VLAN information on the port.
  2. Open the VLAN topology, enter the user VLAN, check devices and links along the VLAN path, and quickly locate the fault.
  3. Rectify VLAN configurations on the VLAN device management page.
Procedure
  1. Search for terminal access records based on the server MAC address and find out the switch and port connected to the server.

    1. Choose Resource > Network > Equipment > Terminal Resources from the main menu.
    2. Choose Resource Management > Terminal Access Record. Check the terminal access information on the page that is displayed.
    3. Set Terminal MAC to 00-15-5D-3A-DF-08 and search for the target server.
    4. Click in the Operation column of the server, click Locate in Panel, and check the port of access device SW1. The access port is selected.
    5. Ensure that VLAN configuration displayed as tips of port Ge1/1/8 is the same as the VLAN configuration of Device2.

      If the configurations are different, right-click the port, choose Modify VLAN from the shortcut menu, and rectify VLAN configurations.

  2. Check the VLAN path in the VLAN topology and locate the fault.

    1. Choose Resource > Network > Business > VLAN Management from the main menu.
    2. Choose Resource Management > VLAN Device.
    3. Set Device name to SW1 and search for the device.
    4. Click in the Operation column of SW1 to locate the device in the topology.
    5. Click VLAN 2 in the VLAN list on the right to display VLAN member devices and allowed paths in the topology. Two devices with green icons are member devices of VLAN 2. However, the link between the two devices is yellow, indicating that VLAN 2 is not allowed to pass through.
    6. Move the cursor to the link and check the tips: SW2's port Ge1/1/5 is Access and VLAN 2 is not allowed to pass through. The configurations are incorrect.

  3. Rectify the configurations.

    1. Right-click the device in the VLAN topology and choose VLAN Management.
    2. On the VLAN device management page that is displayed, click Configure Port VLAN.
    3. Set port VLAN parameters: Set Type to Trunk and Allowed VLAN to 2.
    4. Click Select Interface and select Ge1/1/5.
    5. Click Confirm.

Monitoring and Fine-Tuning VLANs in the Topology During Organizational Capacity Expansion and Adjustment

During organizational capacity expansion and adjustment, VLAN deployment and adjustment are performed in batches, which likely results in few deployment errors. This topic describes how to quickly locate VLAN deployment errors.

Scenario

A company has adjusted its organizational structure to meet service growth requirements. Figure 12-13 shows the networking diagram after the adjustment. Network administrator Wally monitors VLAN deployment in the VLAN topology in advance, detects deployment errors in a timely manner, and fine-tunes VLANs in the topology.

Networking Diagram
Figure 12-13 Network planning of an enterprise
Prerequisites
  • Devices have been added to eSight.
  • SNMP and Telnet parameters have been set as planned on devices and eSight.
Configuration Roadmap
  1. Open the VLAN topology, enter the user VLAN, check devices and links along the VLAN path, and quickly locate the fault.
  2. Fine-tune VLANs in the topology.
Procedure
  1. Check the VLAN 2 path in the VLAN topology and locate the fault.

    1. Choose Resource > Network > Business > VLAN Management from the main menu.
    2. Choose VLAN Topology > VLAN Topology.
    3. Click VLAN 2 in the VLAN list on the right to display VLAN member devices and allowed paths in the topology. SW1 has a blue icon and SW3 has a yellow icon. SW3 is not a member device of VLAN 2.
    4. The link between SW1 and SW3 is yellow. Move the cursor to the link and check the tips: SW3's upstream port Ge1/1/5 is Hybrid and VLAN 2 is not allowed to pass through. SW1's downstream port Ge1/1/1 is Hybrid and VLAN 2 is allowed to pass through.

  2. The configurations are incorrect. Rectify the configurations by adding ports connecting SW1 and SW3 to VLAN 2.

    1. Right-click SW3 in the VLAN topology and choose Add to VLAN. The device icon is changed to blue.
    2. Right-click the link connecting SW1 and SW3 in the VLAN topology and choose Add to VLAN. The link icon is changed to blue. The recovery is completed.

      You can perform the Add to VLAN operation only when the VLAN types on the two sides of the port are the same.

  3. Check the VLAN 3 path in the VLAN topology and locate the fault.

    1. Click VLAN 3 in the VLAN list on the right to display VLAN member devices and allowed paths in the topology. SW2 and SW4 have blue icons. The two devices are member devices of VLAN 3.
    2. The link between SW2 and SW4 is yellow. Move the cursor to the link and check the tips: SW4's upstream port Ge1/1/6 is Access and the PVID is VLAN 3. SW2's downstream port Ge1/1/4 is Trunk and VLAN 3 is allowed to pass through.

  4. The configurations are incorrect. Rectify the configurations by changing SW4's upstream port to Trunk.

    1. Right-click SW4 in the VLAN topology and choose VLAN Management.
    2. On the VLAN device management page that is displayed, click Configure Port VLAN.
    3. Set port VLAN parameters: Set Type to Trunk and Allowed VLAN to 3.
    4. Click Select Interface and select Ge1/1/6.
    5. Click Confirm.
