Static
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 Static Adaptive Load Balance
Description
A bonding interface is configured in DUT0 using the adaptive load balance in static mode. This mode can be used to achieve load-balancing in transmission and reception. In this scenario, transmission load balancing is performed using 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 adaptive-load-balance set interfaces ethernet eth0p0 bond-group bond0 set interfaces ethernet eth0p4 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 eth1 bridge-group bridge br0 set interfaces ethernet eth2 bridge-group bridge br0 set system login user admin authentication encrypted-password '$6$GSjsCj8gHLv$/VcqU6FLi6CT2Oxn0MJQ2C2tqnRDrYKNF8HIYWJp68nvXvPdFccDsT04.WtigUONbKYrgKg8d6rEs8PjljMkH0'
Step 3: Run the command interfaces bonding show on DUT0 and check whether the output matches the following regular expressions:
bond0\s+192.168.100\.10\/24\s+up\s+upShow output
--------------------------------------------------------------- Name IP Address Admin Oper Vrf Description --------------------------------------------------------------- bond0 192.168.100.10/24 up up fe80::2a0:26ff:fe18:c9/64
Step 4: Run the command interfaces bonding bond0 show ports on DUT0 and check whether the output contains the following tokens:
Bonding Mode: adaptive load balancingShow output
Ethernet Channel Bonding Driver: v6.12.49 Bonding Mode: adaptive load balancing Transmit Hash Policy: layer3+4 (1) Primary Slave: None Currently Active Slave: eth0p0 MII Status: up MII Polling Interval (ms): 100 Up Delay (ms): 0 Down Delay (ms): 0 Peer Notification Delay (ms): 0 Slave Interface: eth0p0 MII Status: up Speed: 1000 Mbps Duplex: full Link Failure Count: 0 Permanent HW addr: 00:a0:26:18:00:c9 Slave queue ID: 0 Slave Interface: eth0p4 MII Status: up Speed: 1000 Mbps Duplex: full Link Failure Count: 0 Permanent HW addr: 02:a0:26:18:00:cc Slave queue ID: 0
Step 5: Ping the IP address 192.168.100.20 from DUT0:
admin@DUT0$ ping 192.168.100.20 count 1 size 56 timeout 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=352 ms --- 192.168.100.20 ping statistics --- 1 packets transmitted, 1 received, 0% packet loss, time 0ms rtt min/avg/max/mdev = 352.178/352.178/352.178/0.000 ms
Step 6: Run the command interfaces bonding bond0 show ports on DUT0 and check whether the output contains the following tokens:
Transmit Hash Policy: layer3+4 (1)Show output
Ethernet Channel Bonding Driver: v6.12.49 Bonding Mode: adaptive load balancing Transmit Hash Policy: layer3+4 (1) Primary Slave: None Currently Active Slave: eth0p0 MII Status: up MII Polling Interval (ms): 100 Up Delay (ms): 0 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 queue ID: 0 Slave Interface: eth0p4 MII Status: up Speed: 1000 Mbps Duplex: full Link Failure Count: 0 Permanent HW addr: 02:a0:26:18:00:cc Slave queue ID: 0
Step 7: Run the command interfaces ethernet clear on DUT0.
Step 8: Initiate a bandwidth test from DUT0 to DUT1
