Usage Guidelines

After VLAN aggregation is configured on a device, you can determine whether VLAN aggregation has been correctly configured by running the display sub-vlan command to check information about sub-VLANs and check which sub-VLANs are contained in a super-VLAN.

When using the display sub-vlan command, note the following issues:

If vlan-id is not specified, information about all sub-VLANs on the device is displayed.
If vlan-id is specified, information about a specific sub-VLAN is displayed.

Before running the display sub-vlan command, ensure that the device is configured with sub-VLANs. Otherwise, no command output is displayed.
