Static

These scenarios cover some aspects related to link-aggregation (combining multiple network connections simultaneously to increase throughput, provide redundancy, or both). On OSDx, this can be achieved using bonding interfaces.

Test Static Transmit Load Balance

Description

A bonding interface is configured in DUT0 using the transmit load balance in static mode. This mode can be used to achieve load-balancing in transmission. In this scenario, transmission load balancing is performed via a hash policy.

Scenario

Example 1

Step 1: Set the following configuration in DUT0 :

set interfaces bonding bond0 address 192.168.100.10/24
set interfaces bonding bond0 disable-dynamic-lb
set interfaces bonding bond0 hash-policy layer3+4
set interfaces bonding bond0 miimon 100
set interfaces bonding bond0 mode transmit-load-balance
set interfaces ethernet eth0p0 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 bridge br0 address 192.168.100.20/24
set interfaces bridge br0 stp version rstp
set interfaces ethernet eth0 bridge-group bridge br0
set interfaces ethernet eth2 bridge-group bridge br0
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+up
Show output
---------------------------------------------------------------

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 1
Show 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=0.380 ms

--- 192.168.100.20 ping statistics ---
1 packets transmitted, 1 received, 0% packet loss, time 0ms
rtt min/avg/max/mdev = 0.380/0.380/0.380/0.000 ms

Step 6: Run command interfaces bonding bond0 show ports at DUT0 and check if output contains the following tokens:

Transmit Hash Policy: layer3+4 (1)
Show output
Ethernet Channel Bonding Driver: v6.12.20

Bonding Mode: transmit load balancing
Transmit Hash Policy: layer3+4 (1)
Primary Slave: None

Duplex: full
Link Failure Count: 0
Permanent HW addr: 00:a0:26:16:00:16
Slave queue ID: 0

Step 7: Run command interfaces ethernet clear at DUT0.

Step 8: Initiate a bandwidth test from DUT0 to DUT1
