Chapter 4 Configuring Controller SettingsWireless Device Access
Configuring Multicast Mode
Using the CLI to View Multicast Groups
Use these commands to view multicast groups using the controller CLI.
To see all the multicast groups and their corresponding MGIDs, enter this command:
show network multicast mgid summary
Information similar to the following appears:
Layer2 MGID Mapping:
-------------------
InterfaceName vlanId MGID
-------------------------------- ------ ----
management 0 0
test 0 9
wired 20 8
Layer3 MGID Mapping:
-------------------
Number of Layer3 MGIDs........................... 1
Group address Vlan MGID
--------------- ---- ----
239.255.255.250 0 550
To see all the clients joined to the multicast group in a specific MGID, enter this command:
show network multicast mgid detail mgid_value
where the mgid_value parameter is a number between 550 and 4095.
Information similar to the following appears:
Mgid........................................ 550
Multicast Group Address..................... 239.255.255.250
Vlan........................................ 0
Rx Packet Count............................. 807399588
No of clients............................... 1
Client List.................................
Client MAC Expire Time (mm:ss)
00:13:02:23:82:ad 0:20
Using the CLI to View an Access Point’s Multicast Client Table
To help troubleshoot roaming events, you can view an access point’s multicast client table from the
controller by performing a remote debug of the access point. Follow these steps to do so using the
controller CLI:
Step 1 To initiate a remote debug of the access point, enter this command:
debug ap enable Cisco_AP
Step 2 To see all of the MGIDs on the access point and the number of clients per WLAN, enter this command:
debug ap command show capwap mcast mgid allCisco_AP
Step 3 To see all of the clients per MGID on the access point and the number of clients per WLAN, enter this
command:
debug ap command show capwap mcast mgid id mgid_valueCisco_AP
