CRS312 port mirror

Fri Jun 24, 2022 3:24 pm

Hi I am trying to set up port mirroring on a CRS312.
In my scheme, there are two servers connected to the switch with two links of 10 Gb / s each.
There is one PC for traffic pickup, connected by a 1 Gbps link.
Then the traffic goes through CCR1009, the speed is not more than 300 Mbps.
I tried to capture traffic from the required vlans using ACLs and using forwarding, but I can't get a complete copy of the traffic.
As a test, I'm trying to download several zip archives via ftp to the server and then restore a copy of the dump using wireshark. Half the time I can't open archives. This is one of the bugs in wireshark:
[TCP Previous segment not captured] FTP Data: 1410 bytes (PASV) (RETR 10M_1.zip)
I have tried both routeros and swos - the problem remains
