[f-nsp] LACP with Foundry and Linux Machine

[Rupesh Basnet]

Hi Erich,

I tried changing LACP rates with mode 4 but status was the same and 
linux box was also not able to get partner MAC on its aggregation 
status. I tried with balance-rr mode as well but same, only single MAC 
was obtained under Load Balancing on foundry. I can pass traffic from 
the bonded interface but still don't have any idea if those interfaces 
are really bonded and load balance is happening.

*Status on Linux Box with Mode1:*
Bonding Mode: load balancing (round-robin)
MII Status: up
MII Polling Interval (ms): 30000
Up Delay (ms): 0
Down Delay (ms): 0

Slave Interface: eth0
MII Status: up
Speed: 1000 Mbps
Duplex: full
Link Failure Count: 0
Permanent HW addr: 00:e0:ed:2b:a1:96
Slave queue ID: 0

Slave Interface: eth1
MII Status: up
Speed: 1000 Mbps
Duplex: full
Link Failure Count: 0
Permanent HW addr: 00:e0:ed:2b:a1:97
Slave queue ID: 0

*Status on Linux Box with mode 4:*
Bonding Mode: IEEE 802.3ad Dynamic link aggregation
Transmit Hash Policy: layer2 (0)
MII Status: up
MII Polling Interval (ms): 30000
Up Delay (ms): 0
Down Delay (ms): 0

802.3ad info
LACP rate: slow
Min links: 0
Aggregator selection policy (ad_select): stable
Active Aggregator Info:
     Aggregator ID: 1
     Number of ports: 1
     Actor Key: 17
     Partner Key: 1
     Partner Mac Address: 00:00:00:00:00:00

Slave Interface: eth0
MII Status: up
Speed: 1000 Mbps
Duplex: full
Link Failure Count: 0
Permanent HW addr: 00:e0:ed:2b:a1:96
Aggregator ID: 1
Slave queue ID: 0

Slave Interface: eth1
MII Status: up
Speed: 1000 Mbps
Duplex: full
Link Failure Count: 0
Permanent HW addr: 00:e0:ed:2b:a1:97
Aggregator ID: 2
Slave queue ID: 0
