Have a wireless LAN deployment whereby we have multiple LWAPP (1242AG) at different regional offices connecting over the existing wired network and WAN to a central 5508 WLC.
Different wireless users 'break out' onto various VLAN's off the back of the WLC at the central location and can access all the centralised services fine.
However when they print to a local printer in the office the printing traffic is going to the central site and back again to the printer located next to the user....
Client -> LWAPP -> Wired LAN -> WAN -> Central WLC -> WAN -> Wired LAN -> Printer
Printing performance is terrible due to the latency of going over the WAN to the central WLC and back across the WAN to the printer.
Is there any way that we can 'break out' printer traffic onto a VLAN on the LAN whilst still having the rest going to the WLC?
A HREAP can support both local switched and central switched WLANs in the same time, however a WLAN can't support both local switch and central switch mode in the same time.
So basically you can create two WLANs in the WLC, one for local printing which need to be configured as locally switched, another for internet/email traffic which need to be confgigured as centrally switched. You can then apply these two WLANs into the HREAPs in the remote office, so that local printing traffic will not go through WLC, but the internet/email traffic will be sent to WLC.
If you don't want to use two WLANs for different traffic, then it is out of WLC's capability, you have to use wired method, for example, you can configure a WLAN for local switching, then configure routing in the first hop L3 equipment of the HREAP, so that local printing traffic will be routed to local printer, internet/email traffic will be routed to central site.
