On a 4507 switch, I have several VLANs defined. I'm defining ACLs for these and have run into a problem allowing printing between two VLANs.
VLAN 2 is defined for public devices and VLAN 6 for staff. Public devices have no need to interact with staff devices at all, including printers, so I deny access to VLAN 6 in the ACL. Staff devices only need to interact with printers in VLAN 2 and no other devices. ACLs are applied inbound on the respective VLAN interfaces.
If I include these lines in the respective ACLs, printing from VLAN 6 to a printer in VLAN 2 fails. (note: to keep it shorter, I only included the pertinent ACL lines.)
In debugging this, I see the PC in VLAN 6 make attempts to connect from any number of various ports (1400, 1500, 1600â¦) to establish the connection to the printer in VLAN 2 on port 9100. If I change the ACL for VLAN 6 to the following, printing will now work, but this allows access to all devices in VLAN 2 - not just the printers.
access-list 106 deny ip any 10.50.0.1 0.0.255.0
access-list 106 permit ip any any
I've seen various forum discussions concerning this, but haven't found any solutions that work here. Yet, I do see that others are limiting printing only to port 9100. So, I wanted to know how to configure the ACLs to only allow printing between the VLANs.
