Bonding
These scenarios cover some aspects related to link-aggregation, which is the technique of combining multiple network connections in parallel in order to increase throughput, to provide redundancy or both. On OSDx, this can be achieved by using bonding interfaces.
Test Round-Robin Mode
Description
A bonding interface is configured in DUT0 using the round-robin mode. This mode can be used to achieve load-balancing.
Scenario
Step 1: Set the following configuration in DUT0
:
set interfaces bonding bond0 address 192.168.100.10/24 set interfaces bonding bond0 miimon 100 set interfaces bonding bond0 mode round-robin set interfaces ethernet eth0 bond-group bond0 set interfaces ethernet eth1 bond-group bond0 set system login user admin authentication encrypted-password '$6$GSjsCj8gHLv$/VcqU6FLi6CT2Oxn0MJQ2C2tqnRDrYKNF8HIYWJp68nvXvPdFccDsT04.WtigUONbKYrgKg8d6rEs8PjljMkH0'
Step 2: Set the following configuration in DUT1
:
set interfaces ethernet eth0 address 192.168.100.20/24 set system login user admin authentication encrypted-password '$6$GSjsCj8gHLv$/VcqU6FLi6CT2Oxn0MJQ2C2tqnRDrYKNF8HIYWJp68nvXvPdFccDsT04.WtigUONbKYrgKg8d6rEs8PjljMkH0'
Step 3: Run command interfaces bonding show
at DUT0
and check if output matches the following regular expressions:
bond0\s+192.168.100\.10\/24\s+up\s+upShow output
------------------------------------------------------------------ Name IP Address Admin Oper Vrf Description ------------------------------------------------------------------ bond0 192.168.100.10/24 up up fe80::dcad:beff:feef:6c01/64
Step 4: Run command interfaces bonding bond0 show ports
at DUT0
and check if output contains the following tokens:

Step 5: Ping IP address 192.168.100.20
from DUT0
:
admin@DUT0$ ping 192.168.100.20 count 1 size 56 timeout 1Show output
PING 192.168.100.20 (192.168.100.20) 56(84) bytes of data. 64 bytes from 192.168.100.20: icmp_seq=1 ttl=64 time=0.328 ms --- 192.168.100.20 ping statistics --- 1 packets transmitted, 1 received, 0% packet loss, time 0ms rtt min/avg/max/mdev = 0.328/0.328/0.328/0.000 ms
Step 6: Run command interfaces ethernet clear
at DUT0
.
Step 7: Initiate a bandwidth test from DUT0
to DUT1
