Additional SPAN Considerations

When configuring the SPAN, keep in mind:

The source port can be an Ethernet port, a virtual Ethernet port or a VLAN interface. A standard SPAN session will only SPAN source and destination on the same physical (ESX) host.
The destination port can be any physical or virtual Ethernet port. It cannot be a port channel.
All destinations for a SPAN session must be on the same host. As an example, you cannot have one SPAN session with a VLAN as a source (on one host) and two destinations that are on different physical hosts.
There is a limit of 16 SPAN sessions on the Cisco Nexus 1000V, but no more than 4 can have the same source (such as a VLAN). In the following example, both monitor sessions reference VLAN 152 as a source, therefore, only 2 more monitor sessions can be configured using VLAN 152 as the source.
```
monitor session 1
  source vlan 152 both
  destination interface Vethernet6
  no shut
monitor session 2
  source vlan 152 both
  destination interface Vethernet9
  no shut
```
