Hi All,
Just want to ask, is there any configuration on catalyst 3750 that will allow specific port on only one pc?
or in any way is it possible to open a specific port to one pc.
thank you and hope you may help me.

Hi,
If you are wishing to restrict access on a switchport to a single PC, you could try the port security function. This feature will allow you to tie an interface down to just a single MAC address - if any other MAC addresses are detected on the port you can configure the interface to be err-disabled.
The following configuration guide explains the commands for the Cisco 3750 switch:
An example would be:
interface fa0/1
switchport mode access
switchport access vlan 10
switchport port-security mac-address 1111.2222.3333
Hope this helps,
Many thanks

Hi
there is one more possibility
(config)#errdisable recovery interval ?
<30-86400> timer-interval(sec)
on the interface:
switchport mode access
switchport port-security
switchport port-security mac-address sticky
If a PC is connected, is put down by the Switch automatically the MAC :
switchport port-security mac-address sticky 11112222.3333 vlan access

Hi Nelba,
This is not a Cisco issue where you need to check how to open up the port on one PC but still if you check this out on Google!!
Here are just some results which i found for you:

Also if you need to have specific address sending traffic to specific ports you can use port acls for the same.
