I am a bit confused ... aparently CRS125 series switches can do some kind of link aggregation. According to wiki:
https://wiki.mikrotik.com/wiki/Manual:C ... t_trunking
Port trunking is used when a larger amount of bandwidth is required, this is done by creating a static link aggregation group, which also provides hardware automatic failover and load balancing for CRS1xx/CRS2xx series switches. By adding two 1Gbps interfaces to a trunk, you can increase the theoretical bandwidth limit to 2Gbps. Make sure that all trunked interfaces are linked to the same speed rates.
Note: CRS1xx/CRS2xx series switches aggregate traffic using the built-in Switch Chip without using CPU resources, to route the traffic a router with a powerful CPU is required to handle the aggregated traffic.
There are no settings... just trunk members and thats it. Further on in the same wiki article, the bonding interface has LACP but does not use hardware acceleration:
https://wiki.mikrotik.com/wiki/Manual:C ... ks#Bonding
Unlike CRS1xx/CRS2xx series switches that use the built-in Switch Chip to create a aggregated link group, a router will use the CPU to create the aggregated link group.
To create a bonding interface for ether1,ether2,ether3,ether4, use these commands on the Router:
add mode=balance-xor name=bond1 slaves=ether1,ether2,ether3,ether4\
Warning: Don't use bonding interfaces on CRS1xx/CRS2xx series devices, bonding interface does NOT use the built-in Switch Chip to create aggregated link group and will overload the CPU instantly. For CRS series device use only port trunking.
So what is this "trunk" feature and how can I use it to connect for example a CRS125 switch to a CSS326-24G (or maybe CCR) with 2Gbps ?? Is it compatible with other brands of switches/routers/nas? It looks like this port trunking is not 802.3ad (LACP) or is it?
anyone figured this out?
