Broadcast
This scenario covers 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 Broadcast
Description
A bonding interface is configured in DUT0 using the broadcast mode. This mode can be used to achieve a higher degree of fault-tolerance.
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 miimon 100 set interfaces bonding bond0 mode broadcast set interfaces ethernet eth0p0 bond-group bond0 set interfaces ethernet eth0p1 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 eth2 bridge-group bridge br0 set interfaces ethernet eth3 bridge-group bridge br0 set system login user admin authentication encrypted-password '$6$GSjsCj8gHLv$/VcqU6FLi6CT2Oxn0MJQ2C2tqnRDrYKNF8HIYWJp68nvXvPdFccDsT04.WtigUONbKYrgKg8d6rEs8PjljMkH0'
Step 3: Run command interfaces bonding show at DUT0 and check if output matches the following regular expressions:
bond0\s+192.168.100\.10\/24\s+up\s+upShow output
-------------------------------------------------------------- Name IP Address Admin Oper Vrf Description -------------------------------------------------------------- bond0 192.168.100.10/24 up up fe80::a0:26ff:fe16:15/64
Step 4: Run command interfaces bonding bond0 show ports at DUT0 and check if output contains the following tokens:
Bonding Mode: fault-tolerance (broadcast)Show output
Ethernet Channel Bonding Driver: v6.1.55 Bonding Mode: fault-tolerance (broadcast) MII Status: up MII Polling Interval (ms): 100 Up Delay (ms): 0 Down Delay (ms): 0 Peer Notification Delay (ms): 0 Slave Interface: eth0p1 MII Status: up Speed: 1000 Mbps Duplex: full Link Failure Count: 0 Permanent HW addr: 02:a0:26:16:00:15 Slave queue ID: 0 Slave Interface: eth0p0 MII Status: up Speed: 1000 Mbps Duplex: full Link Failure Count: 0 Permanent HW addr: 00:a0:26:16:00:15 Slave queue ID: 0
Step 5: Ping IP address 192.168.100.20 from DUT0:
admin@DUT0$ 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=0.375 ms --- 192.168.100.20 ping statistics --- 1 packets transmitted, 1 received, 0% packet loss, time 0ms rtt min/avg/max/mdev = 0.375/0.375/0.375/0.000 ms
Step 6: Run command interfaces ethernet clear at DUT0.
Step 7: Ping IP address 192.168.100.20 from DUT0:
admin@DUT0$ ping 192.168.100.20 count 5 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=0.388 ms 64 bytes from 192.168.100.20: icmp_seq=2 ttl=64 time=0.382 ms 64 bytes from 192.168.100.20: icmp_seq=2 ttl=64 time=0.388 ms (DUP!) 64 bytes from 192.168.100.20: icmp_seq=3 ttl=64 time=0.374 ms 64 bytes from 192.168.100.20: icmp_seq=3 ttl=64 time=0.377 ms (DUP!) 64 bytes from 192.168.100.20: icmp_seq=4 ttl=64 time=0.365 ms 64 bytes from 192.168.100.20: icmp_seq=4 ttl=64 time=0.369 ms (DUP!) 64 bytes from 192.168.100.20: icmp_seq=5 ttl=64 time=0.357 ms --- 192.168.100.20 ping statistics --- 5 packets transmitted, 5 received, +3 duplicates, 0% packet loss, time 4074ms rtt min/avg/max/mdev = 0.357/0.375/0.388/0.010 ms
Step 8: Run command interfaces ethernet show counters at DUT0 and check if output matches the following regular expressions:
eth0p0 \s+up\s+\d+\s+\d+\s+0\s+(?![0-4])\d+ eth0p1 \s+up\s+\d+\s+\d+\s+0\s+(?![0-4])\d+Show output
