Switch for SFP+

On the CRS 3xx line, use vlan filtering instead. This guarantees hardware offloading.

PS. Do not use this method on the 1xx or 2xx lines.

/interface bonding
add mode=802.3ad name=bond-inet slaves=ether9,ether10,ether8 transmit-hash-policy=layer-2-and-3

/interface bridge
add name=bridge vlan-filtering=yes

/interface bridge port
add bridge=bridge interface=bond-inet
add bridge=bridge interface=sfp1

/interface bridge vlan
add bridge=bridge tagged=bond-inet,sfp1 vlan-ids=201

This works well on my CRSs:

/interface bonding
add mode=802.3ad name=bond-inet slaves=ether9,ether10,ether8 transmit-hash-policy=layer-2-and-3

/interface bridge port
add bridge=br-cabase interface=bond-inet
add bridge=br-cabase interface=sfp1

But if I want to bridge vlans behind some bonding Instead of bridging phy interfaces, cpu explodes:

/interface vlan
add name=vl201-mmen vlan-id=201 interface=sfp1
add name=vl201-mment vlan-id=201 interface=bond-inet

/interface bridge port
add bridge=br-mment interface=vl201-mmen
add bridge=br-mment interface=vl201-mment

Thanks. I am currently using CRS326-24G-2S+ (with routerOS) for this, but when I want to do vlan trunking through the bonding, cpu load grows from 3% to more than 90%.
I'm consulting Mikrotik's support in the meantime, because routerOS probably doesn't take advantage of the switch hardware as swOS would.

    Mikrotik is a decent product and I'm always amazed at their features set, but...

    Using the UI to configuring the switch will punt too much traffic toward the CPU.  However, it is possible to configure the switch fabric with the cli and attain the desired results.

    It does not compare to a JNP QFX5100 or a Extreme Network x650, x670...  etc.

Have you actually looked at Mikrotik switches?  I don't like the OS, but the hardware does what you want it to.


If necessary, buy your SFP modules from FS.com and get them coded as Mikrotik modules at the factory - that's what we do for Cisco, Brocade, Juniper, Extreme, etc.

Even the top-of-the-line Mikrotik only costs US$899.

Thank you. The problem is that to get a price lower than U$D 3000 I have to resort to a used device.

Used Juniper QFX5100-48T will do it. Probably overkill but you can grab one cheap @ebay

Good afternoon.

I'm looking for a switch with the following capabilities:
. transport for more than 20 gbps
. link aggregation LACP
. slots for SFP+
. seamlessly when trunking vlans through the link aggregation.

And essentially that doesn't exceed US$D 2000 and is compatible with
10GBASE-ER and/or 10GBASE-ZR modules that are not from the vendor itself
(e.g. SPFs: Huawei, Mikrotik, Sumitomo, OEMs).

If any of you have a good experience with a device that meets these
requirements (which are minimal with the exception of price and
compatibility) ?
