Hi,

It doesn matter if it is stack or non-stack still the limiation is only 2.( Stack will be considered as 1).

The Local SPAN session limit is 2 but you can use RSPAN configuration for the same.

These are the local SPAN and RSPAN session limits:

 

Total Sessions per SwitchLocal SPAN SessionsRSPAN Source SessionsRSPAN Destination Sessions

66

2 (ingress or egress or both)

0

64

1 ingress

1 (ingress or egress or both)

1 or 2 egress

0

 

 

 

 

 

Local SPAN and RSPAN Source and Destination Limits

 

These are the local SPAN and RSPAN source and destination limits:

 

 

 

Sources and DestinationsLocal SPAN SessionsRSPAN Source SessionsRSPAN Destination Sessions

Egress sources

1 (0 with a remote SPAN source session configured)

1 (0 with a local SPAN egress source session configured)

1 RSPAN VLAN

Ingress sources
