doubts about trunks and vlans
doubts about trunks and vlans
Im configuring a VLAN voice on two different 2948 baseline switches. Im create a VLAN voice (with vlan ID 2 and named it "Voice") individually, I mean, on each switch ("SISTEMAS 1" and "SISTEMAS 2"), but I dont know if this kind of configuration is correct, I mean, I know the VLAN configuration in one switch have to replicate to other if port trunk is configured on both, but how can I configure the trunk ports on both?
You have to know that 3com switches is not my specialty.
I tried with Link aggregation on 47th port on both switches and I used a crossover cable between them, but nothing.
The next screenshots of the link aggregation configuration on SISTEMAS 2 switch (but SISTEMAS 1 have the same configuration on the same port):



What kind of configuration I have to make to both switches (and others of the same type) handle and share the same VLAN configuration?

Re: doubts about trunks and vlans
Please do not confuse a "vlan trunk" with an "aggregate link", this will only make your head spin in circles.
Most of this confusing comes from the "Cisco Speak" that uses different terms for techniques than the other vendors.
A "trunk" setting in 3com switch tells the port to expect ONLY tagged vlan traffic on both ends of the connection.
Whereas a "port trunk" in Cisco switch says 2 or more ports are combined to increase bandwidth.
Have I helped or hurt this project, hmmmm.
