RE: PVLAN on 3750

I haven't done this in a while so my memory may be rusty but I don't see
in your comfit the community for the Vlans you've created. I'm not near
my CAT to demonstrate the config. (Private-vlan community)

Subject: PVLAN on 3750

Hi fellows,

I just tried to implement a fairly standard PVLAN configration on a
3750,
however it did not work as intended. Configs as follows:

vlan 501
> private-vlan isolated
> !
> vlan 500
> private-vlan primary
> private-vlan association add 501
> !
> int g1/0/3
> switchport mode private-vlan host
> switchport private-vlan host-association 500 501
> !
> int g2/0/5
> switchport mode private-vlan promiscuous
> switchport private-vlan mapping 500 add 501

Configuration is pretty straight-forward but could not identify what
went
wrong. Command "*show interface g1/0/3 private-vlan mapping*" would
produce
a "*Private vlan mapping information is not available*" response,
although "
*show vlan private-vlan*" would show them correctly configured.

As a result, I was unable to reach IP addresses on the 500/501 subnet
that
were located on the isolated vlan/ports

Another question I have (and I could not find much information on the
documentation) is regarding making promiscuous a trunk port (as port
g2/0/5
in the above example). How does it work for VLANs out of the PVLAN
config
that are supposed to be received on this trunk? They also did not seem
to be
working at the time.

Any help is appreciated.
