Check Accessibility Control
This scenario shows how to configure a cellular interface, enabling the accessibility control mechanism that triggers reconnections when network connectivity is lost.
Test Reconnection By Accessibility Control
Description
In DUT0, the cell0 cellular interface is
configured with a cellular profile for which
accessibility control is enabled. Once connectivity
with Google’s DNS public server has been verified, a
situation where 100% of the packets received by the
network are lost is emulated to verify that the
accessibility control mechanism triggers a reconnection.
Scenario
Step 1: Set the following configuration in DUT0 :
set cellular logging level info set cellular profile CELPROFILE accessibility-control ping address 8.8.8.8 set cellular profile CELPROFILE accessibility-control ping interval 10 set cellular profile CELPROFILE apn movistar.es set controllers cellular wwan0 encrypted-pin U2FsdGVkX1+ByQ9ygl/CXtFrovbuyGIwesmk7AvZCnc= set controllers cellular wwan0 pdp 1 profile CELPROFILE set interfaces cellular cell0 address dhcp set interfaces cellular cell0 phy wwan0 pdp 1 set system login user admin authentication encrypted-password '$6$GSjsCj8gHLv$/VcqU6FLi6CT2Oxn0MJQ2C2tqnRDrYKNF8HIYWJp68nvXvPdFccDsT04.WtigUONbKYrgKg8d6rEs8PjljMkH0'
Step 2: Run command controllers cellular wwan0 pdp 1 show network-data-connection at DUT0 and check if output matches the following regular expressions:
Connection status\s* = connectedShow output
Connection status = connected Traffic channel status = active Max. TX channel rate (bps) = 50000000 Max. RX channel rate (bps) = 300000000 IPv4 address = 176.82.165.15 IPv4 mask = 255.255.255.224 IPv4 gateway = 176.82.165.16 IPv4 primary DNS = 80.58.61.248 IPv4 secondary DNS = 80.58.61.249
Note
Once the cellular interface is configured, it can be verified that there is network connectivity by pinging Google's DNS public server.
Step 3: Ping IP address 8.8.8.8 from DUT0:
admin@DUT0$ ping 8.8.8.8 count 1 size 56 timeout 1Show output
PING 8.8.8.8 (8.8.8.8) 56(84) bytes of data. 64 bytes from 8.8.8.8: icmp_seq=1 ttl=115 time=32.3 ms --- 8.8.8.8 ping statistics --- 1 packets transmitted, 1 received, 0% packet loss, time 0ms rtt min/avg/max/mdev = 32.287/32.287/32.287/0.000 ms
Note
The accessibility control is a mechanism where pings are sent at an interval, and to the IP address, configured by the user. The mechanism then waits for a response within this interval. If no response is received before it times out, a second ping is sent and a response is expected within 10 seconds. If there is still no response, two more pings are sent at 5-second intervals. Finally, if there is still no response, the device reconnects to the network.
Note
As a result, you can verify that no reconnection has been recorded in the system logs if you wait long enough.
Step 4: Run command system journal clear at DUT0.
Step 5: Run command system journal show | cat at DUT0 and check if output does not contain the following tokens:
[Device/wwan0] Warning: [PDP#1] Requesting reconnection... [Device/wwan0] Info: WDS[0]: Stopping network connection... [Device/wwan0] Info: [PDP#1] Establishing network connection...Show output

Note
However, when traffic control is applied, it is possible to prove the 'ping' command is failing because ICMP packets are being dropped.
Step 6: Run command system journal clear at DUT0.
Step 7: Modify the following configuration lines in DUT0 :
set interfaces cellular cell0 traffic control in PLOSS set traffic control PLOSS type network-emulator packet-loss 100
Step 8: Expect a failure in the following command:
Ping IP address 8.8.8.8 from DUT0:
admin@DUT0$ ping 8.8.8.8 count 1 size 56 timeout 1Show output
PING 8.8.8.8 (8.8.8.8) 56(84) bytes of data. --- 8.8.8.8 ping statistics --- 1 packets transmitted, 0 received, 100% packet loss, time 0ms
Note
You can verify that a reconnection has been recorded in the system logs if you wait long enough.
Step 9: Run command system journal show | cat at DUT0 and check if output contains the following tokens:

Note
Once the cellular interface is configured, it can be verified that there is network connectivity by pinging Google's DNS public server.
Step 3: Ping IP address 8.8.8.8 from DUT0:
admin@DUT0$ ping 8.8.8.8 count 1 size 56 timeout 1Show output
PING 8.8.8.8 (8.8.8.8) 56(84) bytes of data. 64 bytes from 8.8.8.8: icmp_seq=1 ttl=116 time=39.8 ms --- 8.8.8.8 ping statistics --- 1 packets transmitted, 1 received, 0% packet loss, time 0ms rtt min/avg/max/mdev = 39.768/39.768/39.768/0.000 ms
Note
The accessibility control is a mechanism where pings are sent at an interval, and to the IP address, configured by the user. The mechanism then waits for a response within this interval. If no response is received before it times out, a second ping is sent and a response is expected within 10 seconds. If there is still no response, two more pings are sent at 5-second intervals. Finally, if there is still no response, the device reconnects to the network.
Note
As a result, you can verify that no reconnection has been recorded in the system logs if you wait long enough.
Step 4: Run command system journal clear at DUT0.
Step 5: Run command system journal show | cat at DUT0 and check if output does not contain the following tokens:
