what does it mean

i saw a sentence on CCO: "You can not configure a multi-VLAN port when a trunk is configured on the switch."

i can not understand exactly,that means

1. if i config trunk on a switch,then i can not config multi-vlan port on any port of this switch or

2. if i config trunk on a switch,then i can not config multi-vlan port on this trunk port,but i can config multi-vlan port on other ports.

which is right?

thanks in advance

Re: what does it mean

thanks a lot,i understand now,but this will take me some trouble.

My building,4 floors,one switch cat2924 every floor,so total 4 switches,

and i create 4 vlans on every switch. you know,i connect them by using trunk link. now there are 3 users (one is on the3rd floor,and other two on the 4th floor) want to access the whole network(all 4 vlans),

I think if i can create multi-vlan,then i can resolve this problem,

but now i can not create multi-vlan,what should i do?

my boss do not want to buy anything.

Re: what does it mean

If trunks are already configured on each switches, there are no ways to configure ports to be multi-VLAN. The only solution would be to trunk to those 2 machines or use multi-VLAN ports between switches.

Re: what does it mean

Not all NIC cards are capable of trunking. Check your NIC manuals and see if it supports trunking
