Dears,
I have 2 questions.
if any interface on N7k version 7.X who is broadcasting a heavy traffic which show command should be executed to see from where the traffic is arriving.
I have nexus N7k with all F3 cards do it is necessary to have a M card for IP routing (OSPF,EIGRP) and for OTV.
thanks

Hello,
I am just adding more information.
M1 series are used for all layer 3 operations such as MPLS, OTV and routing protocols but the F1 series are basically layer 2 cards and used for for FEX, FabricPath and etc.
F1 modules can perform layer 3 routing if M1 modules are presented. In fact, M1 modules perform proxy routing.
Cisco released M2 and F2 series afterwards. F2 line cards can also do basic Layer 3 functions but it can not be used for advance L3 features such as OTV or MPLS.
Then, cisco launched F3 cards which are full L3 with all advanced features.
Hope it helps,

Hi,
From the data sheet:
The F3-Series module supports all of the foundational networking protocols needed to build Layer 2 and Layer 3 networks.
see link:

As for the number of broadcast traffic, check the interface that is connected to the end device
sh int ex/x/x det

Dear Reza,
the above command sh int ex/x/x det mentioned is for the known ports and incase If we don't know where the traffic is coming from then ??
In ios we enter a command sh inter summary and we know so and so interface is sending traffic by seeing the increasing output on the particular interface, but in nexus which show command can be helpful ???
Thanks
