Cisco Bug: CSCvt11496 - Support for new Webex behavior to classify webex-meetings audio and video as two separate services

Last Modified

  • Cisco 5500 Series Wireless Controllers

Known Affected Releases

8.10(111.0) 8.5(161.0)

Description (partial)

Symptom:
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.

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