connect the switches and configure each port where you plugged in a fiber with the following lines:
switchport mode trunk
Default encapsulation is isl, if you want dot1q also use the next line:
switchport trunk encapsulation dot1q
By default, all vlans will be trunked. Next, configure the existing switch as a vtp server and the others as clients. Within moments you should see all vlans on the other switches too ("sh vlan" command)
2950 only supports dot1q so "sw tr encapsulation dot1q" is not supported and not required also.
Also I believe if you just have 2 vlans which is already available on your core switch then you need to create VTP domain even just manually create vlans on 2 new switches and if those vlans are not available on core switch then add them there also.
yeah i was thinking that the FW will route them, but I understood in my other post that i can't create vlans in 2950 sw.
now i need another solution
I have a core 2950 SW that connected to a checkpoint FW, and a 2 cisco 2950 SWitces
i want to different networks,
so i connect 1st sw to the core, and the 2nd to the core to (without connecting the 2 new together, 1st will be 192.168.1.x and 2nd will be 192.168.2.x) and i will connect 1 port in the core SW to a dmz NIC in the cp fw. 192.168.2.x
and the existing port connected to the lan nic in 192.168.1.x
it's now so securly but less broadcast i think i have.
A Checkpoint firewall supports dot1q VLANs if the OS it is running on does (CP SecurePlatform does). If you make the port that the FW is connected to on your core 2950 a trunk port (use switchport mode trunk) and create VLAN subinterfaces with the corresponding VLAN numbers (VLAN 1 doesnt have a VLAN number assigned on SPLAT so it is just the IP address bound to the pysical interface), the firewall can route between the VLANs for you.
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
