show broadcast packets on a VLAN

Hi there,

does anyone of you has an idea to get on a Nexus7k (Version: 6.1.2) or a 3560 (Vers. 12.2 (58) SE2) Switch

to display the Broadcast Packets In and/or Out in a VLAN?

On a normal switch port interface that is possible without any problems.

For example with Following commands.:

- Sh interface eth3/46 counters

- Sh int eth3/45

If I want to display me the same on a VLAN that does not work.

Has anyone an idea for that problem?

show broadcast packets on a VLAN

Please try 'show vlan counters'?

What commands have you tried?

show broadcast packets on a VLAN

Hi thx`s,

that was the command I needed.

The command sh vlan id 3000 counters show me the Broadcast Packets in the corresponding VLAN.
As a test I had run a parallel tcpdump test.

But now the captured traffic on the broadcast mac address

( ff:ff:ff:ff:ff:ff ), is much more (overall about 68 broadcast packets) as in the Switch statistic.

The switch has shown me just 4 packets in the same time (about 45 seconds).

Command on the Server:

tcpdump -ni bond0.3000  "ether host ff:ff:ff:ff:ff:ff"

Which number is the right one? Do you have an idea where the problem could be?
