Re: CRS 3xx - L3 ASIC performance testing

Regarding small MTU tests (tests #1 and #2), I suppose that the bottleneck is on the packet generator or receiver side , not the CRS317. As you see, PPS (packets per second) value is almost the same in all three cases, and the transfer speed depends purely on packet size. That is a typical case for ...

Re: L3 hardware offload in FW mode - will there be any other devices than CRS317 supporting this mode?

I agree that HW accelerated security devices at a low price point is a *huge* gap in the market. One feature that would really push the adoption of this is a stateful failover feature between two CRS switches so that it doesn't have to be a customized script + vrrp. RouterOS v7 supports connection ...

Investigation of 98DX3236 switch ship's L3 capabilities is on the roadmap. Please do not misread: it is investigation not development.

Re: L3 hardware offload in FW mode - will there be any other devices than CRS317 supporting this mode?

I wouldn't be so critical regarding ARM vs. MIPS CPU in terms of packet processing. Comparing CPUs relatively to HW (ASIC) performance is similar to comparing 10,000 RPM HDD vs. 7,500 RMP HDD relatively to SSD. Yes, 10K RPM HDD is faster. However, the benefit is negligible in comparison with SSD. Sa...

Re: VRRP sync-connection-tracking setup

If the above information is insufficient, please provide the output of:
/interface export hide-sensitive
/interface/vrrp print detail
from both routers.

If you have a VRRP password set, please manually remove it from the output, since the print command doesn't have a hide-sensitive option.

Re: VRRP sync-connection-tracking setup

If VRRP is up and running, then in most cases, simply setting sync-connection-tracking=yes on both ends should do the trick: VRRP master syncing its connection with the backup router. Some useful info / limitations: MikroTik uses its own proprietary protocol for connection syncing. Therefore, both r...

Re: Not a fan of the new (/) slash notation.

Old (space) notation is supported too. For instance, in v7 you can do still write
ip route print
instead of
/ip/route print
.
Or even

Re: v7.1beta2 [development] is released!

So announcement says CRS309-1G-8S+IN, CRS312-4C+8XG-RM, CRS326-24S+2Q+RM and CRS354-48G-4S+2Q+RM for L3 offload but CRS317 mentioned above as working. I have CRS326-24G-2S+ (arm). Will it take advantage of L3 offloading? If so, what else will? CRS326-24G-2S+ has an older switch chip, for which L3 o...

Re: Memory Requirements

Check the flash disk on the file system. Maybe there are files there that occupy the storage necessary for .npk to install.

Re: v7.1beta1 [development] is released!

Having a 4K limit would be lowish, but it depends on how the acceleration table is managed. I understand that connections over thr 4K limit will not be accelerated, but maybe there could be some effort (now or in the future) to keep useful connections in the hardware table, i.e. connections that ma...

How is HW-offloaded NAT configured? Does it kick in automatically? How do I notice that the 4096 connection limit is reached? Is it shown, which connections aren't HW-offloaded anymore? /interface/ethernet/switch/set switch1 l3hw=fw , where: L3hw ::= fw | no | yes yes -- All traffic gets processed ...

Re: hardware offload on other Marvell DX switches?

Any clue if ipv6 can be supported later? I would like to run 317s as customer edges rather than 2004s, but ipv6 needs to work offloaded at least at some point. Technically, IPv6 can be supported by 317's switch chips. How hard is to implement IPv6 offloading in ROS and when it gets done still in an...
