What should I do to balance the loads between the ports? I would appreciate your help, thank you
…layer 2 and 3 with 802.3ad mode should do fine.
However, balancing accross all interfaces of the bond can only happen if the application (typically the client side, initiating the connection) uses multiple threads/connections (and hence multiple ports - as IP and MAC will stay the same) for transfer.
SMB connections aresingle threaded, so this will not happen…use another protocol.
You can use iperf3 for testing…use the “-P x” parameter for the client, where X is the number of concurrent threads/connections to be used.
Edit: of course, for multiple concurrent sessions from different MACs/IPs/ports - like a number of users concurrently accessing a Service, like a NAS, balancing accross all interfaces will work as well - for the same reason stated above.
topology
ccr1036 ------------------> cr326 ---------------------------> crs326 --------------------------> olt
bonding (vlan) truck 10g truck 10g
Within the bonding I carry ula vlan which is the one that takes the service to customers through pppoe
…what makes the difference is what is on either side of the topology you depicted above.
One or multiple clients/servers behind CCR1036 and one/multiple customers behind olt?
One-to-One, Many-to-one/one-to-Many or Many-to-Many concurrent connections?
Based on your pics and measures in the first port, I’d gather it is a single client/server session only…one MAC/IP and port … hence it will not be balanced accross the interface forming the bond.
If you want to force distribution accross all interface regardless, use balance-rr mode.
balance rr not compaltible for hw
servidor pppoe ----> vlan -----> bonding ------- sfp+ -----> olt
…in my opinion a single ppoe connection will not be balanced across all ports in the bond.
However, should more than one client connect concurrently to the server, the overall bandwidth of the bond can be leveraged. But one client will simply use/receive one interface at a time.
Indeed. PPPoE is protocol on top of ethernet, hence bonding policies will only hash according to L2 … as PPPoE server is only one (single MAC address), the only remaining variable is client MAC address.
