Hello I am working on a project where I have encountered a catlayst switch with the vlans created only using "interface vlan" command
no ip address
There is no "vlan [vlan id] " comanad to creat the VLAN , can any body send me a reference for this ?
Thanks in advance
Switch# config t
switch(config-vlan)#vlan name xyz
it will create a vlan
Please rate if it helps.
No this is not my question of course I know how can I creat a vlan , the questions is
How do those vlan function and forward traffic when there is no vlan command ??!!
If the switch is layer 3 then this catlayst do the intervlan routing .
Do u know about intervlan routing or ???
This is your question or something else???
If you wanna know abt intervlan config then let me know.
no it does not not do inter valn , as you can see there is no IP address configured under the "interface vlan"
My question is how come when you type "show spanning-tree " you can see vlan 163 and access and tunk ports for this vlan , when in fact the command "vlan 163" was not wirtten at all ?
Have got my question
unfortunately this is a customer`s that I do not admin , and getting this is not that easy but I am trying to do so . But for now can we really do so ? ( mean creat a vlan without a vlan command) ?
Normally when I create a L2 Vlan, I used the commands below:
But if you do the command sh vlan and you see these vlan's active then I guess you can create L2 Vlan using the commands below:
int vlan XXX
no ip address
Hope this helps
