My interpretation of the show mac-address-table.. command is that multicast address 0100.5e00.0190 was learned on port gi1/24 by igmp snooping.

SD00#show mac-address-table multicast vlan 3000 igmp-snooping


vlan mac address type learn qos ports

-----+---------------+--------+-----+---+--------------------------------

3000 0100.5e00.0190 static Yes - Gi1/24


My question is: will the global config command below disable snooping on gi/24 for multicast address 0100.5e00.0190.


SD00#sh run | incl mac-address

mac-address-table static 0100.5e00.0190 vlan 3000 interface GigabitEthernet1/24 disable-snooping

SD00#


After configuration of this command "show mac-address-table multicast vlan 3000 igmp-snooping" still shows

vlan mac address type learn qos ports

-----+---------------+--------+-----+---+--------------------------------

3000 0100.5e00.0190 static Yes - Gi1/24


The device is a cat6500 ver. 12.2(18)SXD7b

Hi Simon,


As i told you before on another thread, by default, IGMP snooping is globally enabled on the switch, you can disable it globally on all interfaces using "no ip igmp snooping" in the global configuration.



HTH, please do rate all helpful replies,

Thanks Mohammed. I know that I can disable igmp snooping globally. But this is not what I want. My question was - will


mac-address-table static 0100.5e00.0190 vlan 3000 interface GigabitEthernet1/24 disable-snooping


disable snooping on gi/24 for multicast address 0100.5e00.0190.


Regards

Simon
