Ok I figured it out for the below example
On the cisco switch:
INT E0/1
SWITCHPORT MODE TRUNK
SWITCHPORT TRUNK ENCAP DOT1Q
SWITCHPORT TRUNK ALLOWED VLAN ALL
INT E0/5
SWITCHPORT MODE TRUNK
SWITCHPORT TRUNK ENCAP DOT1Q
SWITCHPORT TRUNK ALLOWED VLAN REMOVE 1,92
As I don't want the Vlans 1 and 92 being advertised from the Site B to Site
A. Hope this helps someone understand Vlan Tagging across multiple vendors.
And restricting vlans on trunks.

Subject: vlan access maps?
Hi,
Here is an alternative scenario to yesterdays question. Basically I am
trying to understand 802.1Q and how vlan access maps work.
Site A (non cisco switch) is connected to Site B (non Cisco Switch) through
a cisco switch as such.
A ----- Cisco ------- B
Link from A is connected to eth 0/1 on the cisco switch
Link from B is connected to eth 0/5 on the cisco switch
Device 1 is connected to eth 0/6 on the cisco switch
Device 2 is connected to eth 0/7 on the cisco switch
Device 1 needs to be a part of the default (vlan 1) from Site A
Device 2 needs to be a part of the vlan 2 from Site B
And I should be able to tag the vlans with 802.1Q and pass them along from
site A to Site B through the cisco Switch
But I want to be able to control which Vlans from site A are advertised to
site B and vice versa
I know that a 3550 switch will not be able to do this, so what switch would
you recommend ( I only have a 2950-48, 3750 and a 4006 lying around, well
have the 3550 also )
And what process would it take to get the above scenario to work
