Check Cellular Oids

This scenario shows how to check cellular interface SNMP OIDs. First, a cellular connection is established, then the SNMP service is configured and the cellular status OIDs are verified.

Test SNMP Cellular Status OIDs

Description

Configure a cellular connection and verify that cellular status information is accessible via SNMP. The following OIDs are checked: signal quality, cell location area code (LAC), radio access technology, tracking area code (TAC), cell identifier, active radio band, RSRP/RSRQ/SINR for primary and 5G ENDC carriers, RSCP and Ec/No.

Scenario

Step 1: Set the following configuration in DUT0 :

set cellular profile CELPROFILE apn movistar.es
set controllers cellular wwan0 sim select socket_1
set controllers cellular wwan0 sim socket socket_1 encrypted-pin U2FsdGVkX183DgVnyid8kWUdsWCgGXf+mi9bH0c+fyk=
set controllers cellular wwan0 sim socket socket_1 pdp 1 profile CELPROFILE
set interfaces cellular cell0 address dhcp
set interfaces cellular cell0 phy wwan0 pdp 1
set service snmp community 'COMMUNITY2TEST!'
set system login user admin authentication encrypted-password '$6$GSjsCj8gHLv$/VcqU6FLi6CT2Oxn0MJQ2C2tqnRDrYKNF8HIYWJp68nvXvPdFccDsT04.WtigUONbKYrgKg8d6rEs8PjljMkH0'

Step 2: Run command controllers cellular wwan0 show network-status at DUT0 and check if output matches the following regular expressions:

      RSSI (dBm) = -89
      SINR (dB) = 0
RX level (dBm) = -67
Coverage level = 4 (**** )

Step 3: 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* = connected

Show output

Connection status               = connected
Traffic channel status          = active
Max. TX channel rate (bps)      = 0
Max. RX channel rate (bps)      = 0

IPv4 secondary DNS              = 80.58.61.249

Step 4: Run command interfaces cellular cell0 show at DUT0 and check if output matches the following regular expressions:
