‎10-23-2019 03:40 AM

i have a requirement of Many to many port miorring to run CC setup on Juniper EX 4300.

Is that possible to achieve it?

I tried couple of options but none of them have given satisfactory input.

Hi milindmistry,

Tried this does JUNOS ELS has a different way to interpret this.

 

Hence not working on EX 4300.

Per this link - https://www.juniper.net/documentation/en_US/release-independent/nce/topics/concept/port-mirroring-co... only 1 active analyzer session is allowed for on EX4300 (also 2300 & 3400).  Using the other documentation noted by @randero provides a method for multiple analyzer sessions.  Then use Firewall Filters to segment which analyzer sees what traffic.

 

To provide for such capabilities on the switch, it might be good idea to save at least 4 interfaces for this operation, if ever required.

Thanks for the link.

 

Just wished to understand, if we can use same input port for both of the instances here?

 

Or can i have 1 instance with many inputs and two recorder output (using no-mac learning) i guess.
