shpw mac address-table output

[fabio.marino]

Hi all,

I have the following output

Vlan    Mac Address       Type        Ports

----    -----------       --------    -----

20    0021.5e99.b690   BLOCKED     Gi2/0/14

  10    0021.5e99.b690    DYNAMIC pv  Gi2/0/14

Vlan 20 is an Isolated vlan and the vlan 10 the primary associated.

Primary Secondary Type              Ports
------- --------- ----------------- ------------------------------------------
10        20      isolated          

Interface Gi2/0/14 is in trunk with ans ESX server to which the host with the above mac address is connected to.

Please is somebody able to understand the output of show mac address table command? What does Blocked mean?

Hi,

The mac is in blocked state to prevent any communication with other hosts in this VLAN. The Mac is learned on vlan 10 to allow communication with promiscious vlan ports
