Hi guys

could anyone help me for the following

(i) how many vlan can able to configure in a switch?
(ii) if we are allocating a segmentation for each vlan, how to do that one in the switch?
(iii) how to set restriction rights to other users login into switch?

clarify the above one ASAP

It depends on the hardware and what it is capable of handling. In most cisco cases you should be able to configure 256...

The set up parts again is determined by what is being used....

Google is your friend for this
