8.10(111.0) 8.5(161.0)

Description (partial)

WLC NBAR / Protocol-Packs only recognize/classify webex-meetings traffic as one "webex-media", but Cisco collaboration BU changed its webex-meetings app behavior to transmit audio as separate webex audio traffic and marked as DSCP EF, and video as separate webex video traffic (marked as AF-41).

WLC NBAR engine / Protocol-Pack is currently not recognizing the two types of webex traffic (video and audio), and hence, not applying AVC rules properly.

Any current WLC AireOS version (up to 8.10) with any current Protocol Pack (up to NBAR2 Protocol Pack 40.0.0 so far)
