Block Printers

[Najeeb Stanikzai]

Hello All,

i have a question. how can i block printing on subnet or vlan on Cisco switch

i would like to block 172.16.20.1 0.0.3.255 subnet to not print.

the printers ips are 172.16.12.20

172.16.12.21

172.16.12.22
 

Thanks

You have two choices: 

1.  You have three IP addresses, so you can create an ACL which includes the three IP address from contacting the printer server.

2.  Or you can create an ACL for the entire subnet.

Hi,

you can use this below ACL.

ip access-list extended blockprinter
 deny   ip 172.16.20.0 0.0.3.255 172.16.12.20 0.0.0.3
 permit ip any any

do i need to create this access list in core switch ?

it is still allow, it did not block the printers.

i have tested it both in core switch and client switch it did not block printers.

Thanks

Which switch has the SVI for the 172.16.20.x network ?

So on a 172.16.20.x client what is the default gateway on that client ie. what IP address.

You need to find the switch with an "interface vlan <x>" with that IP address configured.

Then you need to apply the acl Suresh provided eg -

int vlan <x>
ip address 172.16.20.x 255.255.252.0
ip access-group blockprinter in
