Техническая Инструкция для Cisco Cisco 5760 Wireless LAN Controller

Do not use multicast-unicast for AP capwap multicast mode as a general

●

Verify igmp settings using "show ip igmp groups" command

●

Verify wireless multicast details with "show wireless multicast" and "show wireless multicast
group summary"

●

4. Tune data rates for optimal performance.

Sample data rate configuration for 2.4 Ghz:

ap dot11 24ghz rate RATE_1M disable

ap dot11 24ghz rate RATE_2M disable

ap dot11 24ghz rate RATE_5_5M disable

ap dot11 24ghz rate RATE_6M disable

ap dot11 24ghz rate RATE_9M disable

ap dot11 24ghz rate RATE_11M disable

ap dot11 24ghz rate RATE_12M mandatory

ap dot11 24ghz rate RATE_18M supported

ap dot11 24ghz rate RATE_24M supported

ap dot11 24ghz rate RATE_36M supported

ap dot11 24ghz rate RATE_48M supported

ap dot11 24ghz rate RATE_54M supportedSample data rate configuration for 5 Ghz Ghz:

ap dot11 5ghz rate RATE_6M disable

ap dot11 5ghz rate RATE_9M disable

ap dot11 5ghz rate RATE_12M mandatory

ap dot11 5ghz rate RATE_18M supported

ap dot11 5ghz rate RATE_24M supported

ap dot11 5ghz rate RATE_36M supported

ap dot11 5ghz rate RATE_48M supported

ap dot11 5ghz rate RATE_54M supported

Note: Above is just an example config and the data rates have to be tuned for optimal values on a
per-environment basis.

Tip:

if igmp snoopng cannot be enabled, you can try using:

Broadcast forwarding:

wireless broadcast

Alternatively, you can just forward the broadcasts to a specific VLAN

wireless broadcast vlan <VLAN ID>

WLAN Configuration

Make sure following requirements are met.

1. Disable peer-to-peer blocking action

2. Enable multicast vlan support.

Below is a config example of wlan using external radius authentication with mac-filter and aaa-
override enabled

aaa new-model

aaa group server radius ISE

server name ISE

aaa authentication dot1x ISE group ISE

radius server ISE

address ipv4 x.x.x.x auth-port 1645 acct-port 1646
