In 3750 stack switch , i creat a private vlan101 where gi1/0/22 and vlan102 with gi1/0/23 is community prots which are connected to two different Service provider repectively and valn100 with gi1/0/21 is primary promiscuous port.I also aggregate port(LACP) gi1/0/15 & gi1/0/16 and with same port with another switch (3750).In this switch also VLAN10,20,30,50and 60 and some ports are free. Port channel does not work with private vlan so i want to connect gi1/0/21 throgh firwall port directly,so that i can minimize the collisions and traffic pass through firewall for all valn (inbound,outbond) .
Is promiscuous port communicate with all vlan ports (10,20,30 etc)and rest port as well as private port ?
Please advice me how can i resolve this issue so that i can minimize the collisions without any ACL or VACL and how can i use these valn (100,101,102) completly seprate fron another valn.

Hello Sujet,
>> Is promiscuous port communicate with all vlan ports (10,20,30 etc)and rest port as well as private port ?
the promiscuos port is the L3 routed exit point for the private secondary vlans
in your case g1/0/21 the promiscuous port connects to an external device the firewall.
Has the firewall a path to vlans 10,20,30 ?
if you provide L3 services to primary vlans by configuring SVI interface vlan 100.
I think the best thing would be to have a second link to the firewall acting as the path for normal vlans 10,20,30,50,60.
if the firewall has a third interface I would do so to avoid possible problems in routing over the private vlan.
Hope to help

Dear Giuslar,
My all notes are in bold :-
1:-Is promiscuous port communicate with all vlan ports (10,20,30 etc)and rest port as well as private port
YES
2:- the promiscuos port is the L3 routed exit point for the private secondary vlans -- actually i want to connect the promiscuos port directly through firewall.
3:-in your case g1/0/21 the promiscuous port connects to an external device the firewall.
Has the firewall a path to vlans 10,20,30
--yes is connected throght ether channel port which is port number 5 and 6. which is aggregated with firewall ports (LACP).
an you provide example for L3 services to primary vlans by configuring SVI interface vlan 100.
I have free port on Firewall.
Thanks,
Sujeet
