I have some questions about queues / QoS. We have a RB211 with several cAP ac’s through a managed switch.
Clients: point-of-sale (POS) equipment (both iPads and wired Epson printers on one vlan), guests (wireless) on a second and a 2 office computers and a printer on a third vlan.
We’ve had some occasions where POS traffic (which is the most critical for us) lags. The workers sometimes experience the printers don’t print until maybe a minute or so after requesting the print. I’m not sure if it’s the connection between the client and cAP ac, or deeper in the network. Any way of putting up logging? I guess putting up logging, only catches things from the RB2011 point of view.
All POS traffic from iPads (placing orders, making payments, requesting prints/receipts) goes through the master iPad (192.168.7.41, it’s hardcoded and how the app works). All Epson printers have static IPs (192.168.7.100-110), slave iPads has dynamic IPs (192.168.7.150-200).
I’ve tried to put up a simple queue, but I’m not sure if this is very effective.
Now the guest wifi and employee machines is hard capped at 5M and 10M, but optimal would be to let guests/employees have no cap, but always give priority to POS traffic.
/queue simple
add name=Guests target=GuestWIFI_VLAN priority=8/8 limit-at=4M/4M max-limit=5M/5M
add name=Employees target=Employee_VLAN priority=7/7 limit-at=9M/9M max-limit=10M/10M
add name=Lightspeed target=Lightspeed_VLAN priority=1/1
(fasttrack was enabled, but removed after I implemented the above queue).
Since master iPad and POS printers all have static IPs, could I also set up rules of some sort, to faster expedite all traffic from master iPad to POS printers?
Also a secondary rule to quickly allow all traffic between slave POS iPads (dynamic IP) and the static master iPad? Every client on the POS vlan is equally important, so this probably won’t help(?)
