CRS & Bonding LACP

Sat Aug 01, 2015 8:06 pm

Hi,
I need bonding LACP under CRS at wire speed (without CPU usage).
Is this posible actually? exists some web with examples?

I need a simple usage, for example:
input in ether1 and output in a ether2/ether3 bonding interface

Thanks

/interface bonding
add mode=802.3ad name=EtherChannel slaves="ether1 - SW1/0/17,ether2 - SW2/0/17,ether3 - SW1/0/18,ether4 - SW2/0/18,ether5 - SW1/0/19,ether6 - SW2/0/19,ether7 - SW1/0/20,ether8 - SW2/0/20" transmit-hash-policy=\
    layer-2-and-3
Works great to my Ciscos... Seems (to my surprise) to balance out rather evenly as well. My CCR's hardly breaking a sweat CPU wise.
Regards,
Chris

to my best knowledge, LACP is not supported by hw on the crs. to use /interface bonding, the packet must traverse the 1Gig link between the cpu and the switch chip, so you lose a lot more what you could possibly gain. CRS is limited PPS-wise on the CPU to max 240kpps, which tops around 300Mbps...

all you can do is bonding w/o any protocol (e.g ether-channel mode on), somewhere at /inter ethernet switch trunk

I need hw support on CRS.... I need wire speed.
honestly, I am not clear if possible after read the posts....

CRS has hw support for LACP?

The CRS hardware CAN support LACP, but the functionality has not been implemented through the RouterOS software, so there's no way to configure/control it.

No, CRS does NOT have hw support for bonding nor LACP.

This is quite a big failing.

IF the chipset supports it mikrotik should implement the support in either routeros or swos.

Another very welcome feature would be virtual chassis and support for MCLAG.
