I really like the possibility to use L3HW offloading on the newer high-end devices! However, I also like to monitor my network traffic with Traffic Flow. And sadly, the two are incompatible out of the box (meaning that Traffic Flow simply doesn't see and hence doesn't report flows that are offloaded to the hardware).
I tried tinkering around with switch ACL rules to copy packets to the cpu (on a CRS326-24S+2Q+):
Code: Select all
/interface ethernet switch set 0 l3-hw-offloading=yes mirror-target=cpu
/interface ethernet switch rule add mirror=yes ports=sfp-sfpplus2 rate=1M switch=switch1
- It duplicates the packets, which are then forwarded by the CPU too.
- It copies all packets to the CPU (the rate parameter is simply ignored).
So... does anybody have this kind of setup? Or do I simply have to mirror the traffic off-device and use another device (e.g. server) for flow monitoring? (Which still poses the question of whether switch ACL rules can somehow be used to implement the sampling.)
