Issue/Introduction
This article describes how to adjust the cloud platform when changing a host switch port from Access to Trunk mode. It applies to the initial diagnosis and resolution of similar issues in ZStack Cloud.
Environment
- Product: ZCF
- Component: Cloud
- Version: 3.x-5.5.30
Resolution
- During a low-traffic period, stop the workload before making the network change.
Note:
Before deleting or recreating network resources, confirm the workload impact, record the original network configuration, and ensure that a rollback plan is available.
- After configuring the switch, click Resource Center > Cloud Resource Pool > Virtual Resources > VM Instances on the ZStack Cloud main menu. On the VM instance details page, click Export in the upper-right corner to export a CSV file containing the VM instance IP and MAC addresses.
- Detach the NIC from the VM instance.
- Delete the L3 network and L2 network.
Note:
Before deleting the L3 network and L2 network, ensure that their CIDR information has been recorded.
- Add the L2 network and L3 network again.
- Attach the NIC to the VM instance, and specify its IP address and MAC address.
Note:
Stop the VM instance and record the NIC IP address and MAC address before attaching a NIC. If the VM instance has multiple NICs, record the IP address and MAC address of each NIC separately.
