hello all, i need to vlan a cisco 3548 with 8 vlans. that part is easy, but i want to make a port a member of all 8 vlans and connect it to a pix port so all the vlans can share the firewall interface without being able to see each other. all the vlans will be in the same class c network 192.168.160.x. is this possible? has anyone done this? thanks for any help you can offer.

kabalah,

Can you post us your solution's configuration so everyone else can view it ? This could be also added into the lab scenarios we are working on.

oh mate,

u r really a geek out there. i dont know how u make a single port as the member of 8 vlans and then connect to PIX.
does the PIX u are using supports subinterface ?

i really am happy with this type of setup if it works bcoz there is more than security factor involved

please post your config.


with regards
tsunami

This is what probably worked for him.

Step 1


configure terminal


Enter global configuration mode.

Step 2


interface interface


Enter interface configuration mode, and enter the port to be added to the VLAN.

Step 3


switchport mode multi


Enter the VLAN membership mode for multi-VLAN ports.

Step 4


switchport multi vlan vlan-list


Assign the port to more than one VLAN.
Separate nonconsecutive VLAN IDs with a comma; use a hyphen to designate a range of IDs.

Configuring a switch port for multi-VLAN mode causes VTP to transition to transparent mode, which disables VTP.

Step 5


end


Return to privileged EXEC mode.

Step 6


show interface interface-id switchport


Verify your entries.
