Traffic mirroring to 2 destination ports (1GE- BaseT&10GE -SR) restrictions-best practices

Traffic mirroring to 2 destination ports (1GE- BaseT&10GE -SR) restrictions-best practices

Hi community

we need to mirror all incoming traffic from port A to x2 different ports (B&C). Port A is 10G-LR, port B is 1GE-baseT and port C is 10G-SR.
In regards of the configuration and restrictions:
Is there any configuration issue when there's a media type mismatch between both destination ports?
According to the doc below, it seems that when we mirror traffic to more than x1 destination port, we lose x1 physical port availability because of the loopback port configuration. Is this correct?: https://extremeportal.force.com/ExtrArticleDetail?an=000081804

Is there any other condition/restriction to consider?

Thx in advance.

There shouldn't be any impact to other ports.

looks great. we're using some X620-16x switches so i guess besides the optics, all the ports could be 10G. regarding the way the switch does the mirroring through the ASIC, could this one-to-many mirroring have any impact in any over subscription in the other ports?

You can do this. It works by EXOS mirroring traffic from port A to the loopback port, and the loopback port will use the switch asic to forward the traffic to these two mirror ports. With that being said the loopback port will need to be 10G if you need that one 10G mirror port to get all the traffic.

HI Stephen,

thanks for the feedback. Yep, for sure if port A is let's say a 10G , in case traffic goes over 1G we'll lose some traffic. my wonders is really if it' s techinical possible to configure this setup with mismatch port interface speed both as destination and source.
So when you say 'you will lose one port for the internal loopback' you mean we lose a physical port availability and we can not use it, right?

Thx again
