[c-nsp] Trunking Private VLANs on 6509

[Justin Krejci]

I am trying to trunk private vlans from a Cisco 6509 to some other
switches. There does not appear to be a way to do this but it works
great on a Cisco 4948. Does the 6509 not support doing this or is there
something else needed to make this work?

Here is some sample config.

############
Cisco 4948
############

vlan 850
  private-vlan isolated
vlan 851
  private-vlan primary
  private-vlan association 850

interface GigabitEthernet1/34
 switchport trunk encapsulation dot1q
 switchport trunk allowed vlan 850,900,910,911
 switchport private-vlan trunk allowed vlan 850,900,910,911
 switchport private-vlan association trunk 851 850
 switchport private-vlan association trunk 901 900
 switchport private-vlan association trunk 909 910
 switchport private-vlan association trunk 912 911
 switchport private-vlan association trunk 853 852
 switchport mode private-vlan trunk

interface Vlan851
 ip address x.x.x.1 255.255.255.0
 private-vlan mapping 850



############
Cisco 6509

vlan 850

(everything after this point errors out because "trunk" is not an option
for any of these)
