Cisco publicly released the much anticipated 8.0 code release for their Wireless LAN Controllers a few days ago.
This is a major point release and brings with it some interesting feature enhancements and new options targeted specifically at high-density wireless networks.
Release notes for 220.127.116.11 are available here.
Since 7.4 Cisco have been adding some handy tools to make optimising high-density networks much easier, some of these have been available for a while via hidden CLI commands but are now available publicly and via the WLC GUI. These headline features available to engineers are:
- RX-SOP (7.2 via hidden CLI, 7.4 public CLI, 8.0 GUI)
- Low RSSI Check (7.5 GUI)
- Cisco Optimised Roaming (8.0 GUI)
I had been working on a similar post to the ones above, so rather than rehash the excellent work by those guys I will update this post in a few days with some real-world uses of these features and go over what I’ve found works, what doesn’t work and what to watch out for when configuring these settings.
