Hello,
I configured the private VLANs on a WS-C3750-48P with C3750 Software (C3750-IPSERVICES-M), Version 12.2(35)SE5.
this is the configuration I did:
vlan 500
private-vlan primary
private-vlan association 1100
vlan 1100
private-vlan isolated
!
vlan 1101
private-vlan isolated
!
vlan 1102
private-vlan isolated
!
vlan 1103
private-vlan isolated
!
even if I submit the command private-vlan association 1100-1103 and or try to add the vlan one by one, I am not able to associate more than one private vlan to the primary vlan 500.
Switch#sh vlan private-vlan
Primary Secondary Type Ports
------- --------- ----------------- ------------------------------------------
500 1100 isolated
1101 isolated
1102 isolated
1103 isolated
Any help will be greatly appreciated...
thank you

Hey,
Correct, only one Isolated primary vlan is associated with Primary private vlan. Snippet from configuration guide:
"A primary VLAN can have one isolated VLAN and multiple community VLANs associated with it. An isolated or community VLAN can have only one primary VLAN associated with it."

Hey,
You can have one Isolated vlan per primary vlan.
You ,may also check configuration guide:

Rajeevsh,so if I do not misunderstand, you could associate to a primary VLAN different community vlans, but only one private vlan?
