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”.

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

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 item “FDB (maximum L2 entries)” in the Supported Limits table of the ExtremeXOS Release Notes.
