PVLAN Limitations

The Private VLAN feature has the following limitations:

Note

Note

A maximum of 80% of 4K VLANs can be added to a PVLAN. Adding more VLANS will display the following log error:
<Erro:HAL.VLAN.Error>Slot-<slot>: Failed to add egress vlan translation entry on port <port> due to “Table full”.
An additional limitation applies to BlackDiamond 8000 series modules and Summit family switches, whether or not they are included in a SummitStack. If two or more member VLANs have overlapping ports (where the same ports are assigned to both VLANs), each additional VLAN member with overlapping ports must have a dedicated loopback port. To state it another way, one of the VLAN members with overlapping ports does not require a dedicated loopback port, and the rest of the VLAN members do require a single, dedicated loopback port within each member VLAN.
Note

Note

There is a limit to the number of unique source MAC addresses on the network VLAN of a PVLAN that the switch can manage. It is advised not to exceed the value shown in the Supported Limits table of the ExtremeXOS Release Notes.
