Primary pvlan and multiple isolated vlans.

I'm trying to set up several isolated pvlans and map them to the primary vlan but get this error message:

ENG-4003> (enable) set pvlan 10 21 3/2

Primary private vlan already has an isolated vlan associated.

Failed to add ports to association.

Here is the config so far:

ENG-4003> (enable) sh pvlan

Primary Secondary Secondary-Type Ports

------- --------- ---------------- ------------

10 20 isolated 3/1

10 30 community 3/15-18

10 40 community 3/10-13

- 21 isolated

- 22 isolated

Can't I have more then one isolated vlan mapped to the same primary pvlan?

Re: Primary pvlan and multiple isolated vlans.

You can only have 1 isolated pvlan mapped to a given primary.
