Hi - why 59 entries ?

And how do i get just the NIC MAC of the card plugged into the switch port - just the 1 mac

I thought the "interface gi1/0/14" at end of command would give me 1 MAC the mac of card connected to that port. ?

Also i have esxi host 8 nics - plugged into this cisco 2960. - i can only find 1 of the 8 mac address;s in the mac table of the switch.? - why are they not all listed. - its the source mac in the table isnt it? - if so should i not see in the table that this esx host sent (source) frames through the switch ? - Thanks

How do yo have the NIC's setup in ESXi?

If you clear the counters, wait a little while, and do "show int" for the interfaces in question do you see traffic going both into and out of the port?

Hi giltjr thanks for help

I have clear counters - yes traffic In and OUT


the odd thing is that i have all 6 x 5 (30) esxi host interfaces plugged in the switch. - when i troll through the mac-address table - I can see 50-70 MACs - at best 1 or 2 of the MACs that vcentre or esxi ssh shows me of the MACs of the esxi hosts - are listed in the table.

why would the others not be in there? - they are sending receiving traffic

you are probably seeing the mac addresses of the vm's nics.

are using esx as a router between the vm's and the rest of the network or are you using a vswitchvs witch.

giltrj - Id like to give double points. Thankyou very much

No esx router - It was simply i was seeing the VM MACs in the mac table - I didnt think they would be different to the MACs I see on the vcentre client - network adaptor list.

couldn't see the wood through the trees

Thanks for the points.  There are many times I don't see the forest for the trees.  Just so many things to look at and think about, sometimes we overlook the obvious.
