Check Connection
This scenario shows how to configure a cellular interface and then check for network connectivity by pinging Google’s DNS public server. In addition, some operational commands are executed and the information displayed by them is checked.
Test ICMP Connectivity
Description
In DUT0, the cellular module wwan0 is configured with the PIN code required by the inserted SIM card. Additionally, a Packet Data Protocol (PDP) is configured with the APN corresponding to the SIM card’s operator. Then, the cellular interface cell0 is associated with this PDP and configured to obtain its IP addressing through DHCP. Once it’s configured, the ‘Ping’ command is used to check connectivity with Google’s DNS public server.
Scenario
Step 1: Set the following configuration in DUT0 :
set cellular profile CELPROFILE apn movistar.es set controllers cellular wwan0 encrypted-pin U2FsdGVkX1+kjk7eC6GlMcC2CoAGETiHLxs1nOx8YaE= 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'
Note
Once the cellular module is configured, checking whether the SIM and registration states are correct can be done with the following operational command.
Step 2: Run the command controllers cellular wwan0 show network-status on DUT0 and check whether the output matches the following regular expressions:
SIM status\s* = OK Registration state\s* = registeredShow output
SIM status = OK Registration state = registered Public Land Mobile Network code = HOME[21407] ACT[21422] Public Land Mobile Network name = Movistar Network technology currently in use = lte Current Service Domain registered = cs-ps (capable cs-ps) Current Roaming status = off 3GPP Cell ID = 72016415 Radio Band = eutran-20 Channel = 6400 LTE Tracking Area Code (TAC) = 28673 LTE Carrier Aggregation Info: Primary Cell Info: Band = E-UTRA Band 20 Frequency = 6400 Downlink Bandwidth = 10 MHz Physical Cell ID = 195 Scell State = registered RSRP (dBm) = -77 RSRQ (dB) = -7 RSSI (dBm) = -54 SINR (dB) = 20 Uplink Bandwidth = 10 MHz Secondary Cell Info #0: Band = E-UTRA Band 3 Frequency = 1301 Downlink Bandwidth = 20 MHz Physical Cell ID = 216 Scell State = inactive RSRP (dBm) = -84 RSRQ (dB) = -12 RSSI (dBm) = -61 SINR (dB) = 23 RX level (dBm) = -78 Coverage level = 5 (*****)
Note
On the other hand, checking whether the cellular interface has correctly established the network connection can be done with the following command.
Step 3: Run the command controllers cellular wwan0 pdp 1 show network-data-connection on DUT0 and check whether the 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 = 88.31.127.253 IPv4 mask = 255.255.255.252 IPv4 gateway = 88.31.127.254 IPv4 primary DNS = 80.58.61.248 IPv4 secondary DNS = 80.58.61.249
Note
Additionally, with the previous operational command, the IP address provided by the operator to be used by the cellular interface is displayed. With the following command, it is possible to check if the DHCP client has correctly configured the cellular interface.
Step 4: Run the command interfaces cellular cell0 show on DUT0 and check whether the output matches the following regular expressions:
cell0\s+\d+.\d+.\d+.\d+\/\d+\s+up\s+upShow output
------------------------------------------------------------------ Name IP Address Admin Oper Vrf Description ------------------------------------------------------------------ cell0 88.31.127.253/30 up up fe80::58fa:99ff:fe16:b9c8/64
Note
Once all of the above has been verified, we can be sure that the cellular interface has been correctly configured and there is network connectivity. The latter can be verified, for example, by pinging Google's DNS public server.
Step 5: Ping the 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=117 time=29.1 ms --- 8.8.8.8 ping statistics --- 1 packets transmitted, 1 received, 0% packet loss, time 0ms rtt min/avg/max/mdev = 29.071/29.071/29.071/0.000 ms

Step 4: Run the command interfaces cellular cell0 show on DUT0 and check whether the output matches the following regular expressions:
cell0\s+\d+.\d+.\d+.\d+\/\d+\s+up\s+upShow output
----------------------------------------------------------------- Name IP Address Admin Oper Vrf Description ----------------------------------------------------------------- cell0 37.12.30.106/30 up up fe80::cd0:c4ff:fe14:39e6/64
Note
Once all of the above has been verified, we can be sure that the cellular interface has been correctly configured and there is network connectivity. The latter can be verified, for example, by pinging Google's DNS public server.
Step 5: Ping the 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=113 ms --- 8.8.8.8 ping statistics --- 1 packets transmitted, 1 received, 0% packet loss, time 0ms rtt min/avg/max/mdev = 112.820/112.820/112.820/0.000 ms
