Xor-Hash

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

Test Xor-Hash

Description

A bonding interface is configured in DUT0 using the xor-hash mode. This mode can be used to achieve load-balancing based on the configured 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 hash-policy layer3+4
set interfaces bonding bond0 miimon 100
set interfaces bonding bond0 mode xor-hash
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 eth1 bridge-group bridge br0
set system login user admin authentication encrypted-password '$6$GSjsCj8gHLv$/VcqU6FLi6CT2Oxn0MJQ2C2tqnRDrYKNF8HIYWJp68nvXvPdFccDsT04.WtigUONbKYrgKg8d6rEs8PjljMkH0'

Step 3: Run the command interfaces bonding show on DUT0 and check whether the output matches the following regular expressions:

bond0\s+192.168.100\.10\/24\s+up\s+up
Show output
---------------------------------------------------------------

fe80::2a0:26ff:fe18:c9/64

Step 4: Run the command interfaces bonding bond0 show ports on DUT0 and check whether the output contains the following tokens:

Bonding Mode: load balancing (xor)
Show output
Ethernet Channel Bonding Driver: v6.12.49

Bonding Mode: load balancing (xor)
Transmit Hash Policy: layer3+4 (1)
MII Status: up

Down Delay (ms): 0
Peer Notification Delay (ms): 0

Slave Interface: eth0p0
MII Status: up
Speed: 1000 Mbps
Duplex: full
Link Failure Count: 0
Permanent HW addr: 00:a0:26:18:00:c9

Slave Interface: eth1
MII Status: down
Speed: Unknown
Duplex: Unknown
Link Failure Count: 1
Permanent HW addr: 00:a0:26:18:00:ca
Slave queue ID: 0

Step 5: Ping the 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=345 ms

--- 192.168.100.20 ping statistics ---
1 packets transmitted, 1 received, 0% packet loss, time 0ms
rtt min/avg/max/mdev = 344.506/344.506/344.506/0.000 ms

Step 6: Run the command interfaces ethernet clear on DUT0.

Step 7: Initiate a bandwidth test from DUT0 to DUT1

admin@DUT1$ monitor test performance server port 5001
admin@DUT0$ monitor test performance client 192.168.100.20 duration 5 port 5001 parallel 10
Expect the following output on DUT0:

Step 8: Run the command interfaces ethernet show counters on DUT0 and check whether the output matches the following regular expressions:

eth0p0 \s+up\s+\d{2,}\s+\d+\s+\d+\s+\d{2,}
eth0p4 \s+up\s+\d{2,}\s+\d+\s+\d+\s+\d{2,}
Show output
