The CISCO Informacast cl

Customer Environment

Ruckus Access Points Ruckus Virtual Smart Zone Controller Controller Version: 6.1.0.0.935 Control Plane Software Version: 6.1.0.0.683 AP Firmware Version: 6.1.0.0.1595 Aruba JL261A 2930F-24G-PoE+-4SFP Switch

Root Cause

The software uses SLP(Service Location Protocol) multicast to discover the Informcast server on their LAN Ruckus directed multicast features are suspected to be breaking SLP by converting the multicast to unicast and disabling the same on Eth and WLAN interfaces resolved issues

Symptoms

But the client does not register on the server
Connecting the same client to wired network same VLAN works

Troubleshooting Steps

Packet captures taken on Server
Packet captures were taken on Client
Packet captures were taken on AP uplink and WLAN interfaces
No drops noticed
However, when QOS processing / Directed multicast is enabled on WLAN interface the software does not work as intended
When directed multicast is disabled and QOS processing is disabled on the Ruckus AP WLAN interface the software works without issues

Workaround

Disabled QOS functionality of WLAN logical interface to make the software work
Access the AP via SSH and disable QOS on WLANs that have CISCO Informacast nodes
The following commands can also be run from the AP Diagnostic Script function of SZ
The following commands can also be run from the Remote AP Cli feature of SZ and ZD

set qos igmp_query v2 disable
set qos igmp_query v3 disable
set qos eth0 classification disable
