multicast mac table on Nexus 7000

On IOS I would type:

 

show mac address-table multicast

And see mac tables entries for multicast addresses.

 

Yet on the nexus 7000 version 6.1(2), I cannot - it throws an error.

 

On the Nexus 5500 version 7.0(7)N1(1) the command returns output,as I woudl expect.

 

After checking documentation I cannot seem to find the answer for returning my output on a Nexus 7000.  I am keen to understand the switching paths at layer 2 at a switchport level to validate behaviour.

 

Does anyone know how to achieve this on a Nexus 7000 version 6.1(2) - or does this require an upgrade?

 

Many thanks.

Hi Nicholas,

 

The command "show mac address-table multicast" was introduced in releases 6.2(x) and later so yes, that would require an upgrade. Assuming your gear supports it, the Nexus 7K BU's recommended code is currently NX-OS 6.2(16).

 

Example output on my Nexus 7K:

 

 

 

RTP-AGG1# show mac address-table multicast 
Legend:
* - primary entry, G - Gateway MAC,(R) - Routed MAC, O - Overlay MAC
age - seconds since last seen,+ - primary entry using vPC Peer-Link
VLAN MAC Address Type Age OIFs
---------+-----------------+--------+---------+------------------------------
257 03bf.0001.1234 static - Eth10/24
RTP-AGG1# sh ver | i image kickstart image file is: bootflash:///n7000-s2-kickstart.6.2.16.bin system image file is: bootflash:///n7000-s2-dk9.6.2.16.bin RTP-AGG1# which | i i table.multicast (3238) show mac address-table multicast [ vlan <vlan-id> ]

 

 

 

Hope that helps!

Many thanks indeed. In fairness I was a little embarrassed to as such a rudimentary question!

 

Thank you for your concise response!
