Hybrid ports for shared resources

Use Huawei hybrid ports to let two isolated teams share one server in the same subnet without a router. You decide, per VLAN and per port, which frames leave tagged and which untagged, then trace a frame and its reply through both switches.

Run this lab

It needs Standard: its 5 nodes are set to 7 vCPU and 7,168 MB in total.

In your workspace: Shared, then HCIA-Datacom H12-811 guided labs, then 07 - Hybrid ports for shared resources

Run it on Standard from £5 a day

The free demo can’t run it: it has 6 vCPU and 8 GB, and this lab’s nodes need 7 vCPU and 7,168 MB together. Every lab plan includes every guided lab.

The scenario

Northwind's design and accounts teams share a floor and a subnet (192.168.1.0/24), but compliance says they must not be able to reach each other's PCs. Both teams need the same file server, which sits on another switch. A router would solve it, but this office has none. Huawei switches offer another way: hybrid ports, which let a frame enter in one VLAN and its reply come back in another.

PC1 (design)SW1 GE1/0/1192.168.1.1/2410
PC2 (accounts)SW1 GE1/0/2192.168.1.2/2420
ServerSW2 GE1/0/1192.168.1.100/2430
SW1–SW2 linkGE1/0/10 on both–carries 10, 20 and 30 tagged

What you’ll practise

  • Explain how a hybrid port receives and sends frames using its PVID and its tagged and untagged VLAN lists
  • Configure hybrid ports with port hybrid pvid, untagged vlan and tagged vlan
  • Trace a request and its reply across two switches, VLAN by VLAN
  • Read UT and TG entries in display vlan and the hybrid rows in display port vlan

The tasks

  1. Prepare both switches
  2. Plan before you type
  3. Configure the user ports on SW1
  4. Configure the server port and the link
  5. Test and explain
  6. Read the switch's view
  7. Break it and fix it

The Lab Tasks pane has the scenario, these tasks, the checks to run, hints and the full solution.

How to open this lab

  1. Sign in to your workspace at lab.cloudlabbox.com.

  2. In File Manager, open Shared, then the folder HCIA-Datacom H12-811 guided labs.

  3. Open 07 - Hybrid ports for shared resources and start its nodes, then open Lab Tasks for the scenario and the steps.

The lab is read-only. You can start the nodes and configure the devices, but changes to the topology can’t be saved. To change it, rebuild it in your own folder.
