Description (partial)

This DDTS is for documentation purpose.  Below span limitation is incorrect for N9K Tahoe platform.

1.  The combination of VLAN source session and port source session is not supported.
>> The combination of VLAN source session and port source session is supported for Tahoe platform
2.  VLAN sources are spanned only in the Rx direction.
>> VLAN sources are spanned for both direction for Tahoe platform.

Per lab test result, we found following limitation for Tahoe platform.

3. When a VLAN source configured as BOTH in one session and the physical interface source is being configured in two more sessions(include two), RX span is not supported for physical interface source session.

Tested with N9K-X97160YC-EX only.
For the other Tahoe platform modules, further test is needed before delivery this DDTS to customer. 

Config sample

  source vlan 10 both

monitor session 2
  source interface Ethernet1/1 both   
  destination interface Ethernet1/46
