Prerequisites for Private VLANs
When configuring private VLANs on the device, always use the default Switch Database Management (SDM) template to balance system resources between unicast routes and Layer 2 entries. If another SDM template is configured, use the sdm prefer default global configuration command to set the default template.
Note |
Private VLANs are supported in transparent mode for VTP 1, 2 and 3. Private VLANS are also supported on server mode with VTP 3. |
