Some data I cant find on the Datasheet:
Ethernet-Ports: what speeds at what distance? Jumbo Frames?
CRS317-1G-16S+RM has more ports, better cpu and is cheaper. So?
Comparing a 10G MT Switch with another is "comparing apples to water-melons"? I know this CPUs do only limited routing. Still usefull to route e.g. a managment vlan.As the product naming page explains:
- CRS series: 3
- total number of interfaces: 12
- number of combo 10G Ethernet/SFP ports: 4 (4C+ part of name)
- number of 5G/10G Ethernet ports: 8 (8XG part of name)
The mentioned CRS317-1G-16S+RM fetaures only 1Gbps ports (ethernet) or 10Gbps (SFP+). So it's like comparing apples to water-melons.
And don't let be lead away about device's CPU, it has nothing to do with frame switching. It might be used for routing, but these beasts are switches, not routers (don't let be lead away with the name either).
as seen the test results look like not correct speed that explain in brochure that isCRS312-4C+8XG has Marvell-98DX8212 switch chip and supports the same features as CRS317-1G-16S+ including 10218 byte Jumbo Frames.
Briefly, Ethernet interface link speeds are similar to S+RJ10 module:

We will update the CRS312-4C+8XG documentation regarding that.
