Test Ethernet Stats Through SNMP

Description

Some ping operations are performed and SNMP monitoring is used to check whether interface statistics increase.

Scenario

Step 1: Set the following configuration in DUT1 :

set interfaces ethernet eth0 address 10.0.0.2/24
set protocols static route 0.0.0.0/0 interface eth0
set system login user admin authentication encrypted-password '$6$GSjsCj8gHLv$/VcqU6FLi6CT2Oxn0MJQ2C2tqnRDrYKNF8HIYWJp68nvXvPdFccDsT04.WtigUONbKYrgKg8d6rEs8PjljMkH0'

Step 2: Set the following configuration in DUT0 :

set interfaces ethernet eth0 address 10.0.0.1/24
set protocols static route 0.0.0.0/0 interface eth0
set service snmp community 'COMMUNITY2TEST!'
set system login user admin authentication encrypted-password '$6$GSjsCj8gHLv$/VcqU6FLi6CT2Oxn0MJQ2C2tqnRDrYKNF8HIYWJp68nvXvPdFccDsT04.WtigUONbKYrgKg8d6rEs8PjljMkH0'

Step 3: Run command service snmp walk local-agent v1 COMMUNITY2TEST! oid 1.3.6.1.4.1.2007.6.3.1.10.5 | grep eth0 at DUT0 and expect this output:

Show output
TELDAT-OSDX-MONDB-INTERFACES-MIB::telOSDxMonDBInterfacesEthernetStatsRxBytes."eth0" = INTEGER: 47485524
TELDAT-OSDX-MONDB-INTERFACES-MIB::telOSDxMonDBInterfacesEthernetStatsRxPackets."eth0" = INTEGER: 503962
TELDAT-OSDX-MONDB-INTERFACES-MIB::telOSDxMonDBInterfacesEthernetStatsRxErrors."eth0" = INTEGER: 0
TELDAT-OSDX-MONDB-INTERFACES-MIB::telOSDxMonDBInterfacesEthernetStatsRxMulticasts."eth0" = INTEGER: 9699
TELDAT-OSDX-MONDB-INTERFACES-MIB::telOSDxMonDBInterfacesEthernetStatsRxBroadcasts."eth0" = INTEGER: 1242

TELDAT-OSDX-MONDB-INTERFACES-MIB::telOSDxMonDBInterfacesEthernetStatsTxPackets."eth0" = INTEGER: 1127218
TELDAT-OSDX-MONDB-INTERFACES-MIB::telOSDxMonDBInterfacesEthernetStatsTxErrors."eth0" = INTEGER: 0
TELDAT-OSDX-MONDB-INTERFACES-MIB::telOSDxMonDBInterfacesEthernetStatsTxMulticasts."eth0" = INTEGER: 7960
TELDAT-OSDX-MONDB-INTERFACES-MIB::telOSDxMonDBInterfacesEthernetStatsTxBroadcasts."eth0" = INTEGER: 1412

Note

Generate some traffic between DUT0 and DUT1.

Step 4: Ping IP address 10.0.0.2 from DUT0:

admin@DUT0$ ping 10.0.0.2 count 5 size 56 timeout 1
Show output
PING 10.0.0.2 (10.0.0.2) 56(84) bytes of data.
64 bytes from 10.0.0.2: icmp_seq=1 ttl=64 time=0.660 ms
64 bytes from 10.0.0.2: icmp_seq=2 ttl=64 time=0.377 ms
64 bytes from 10.0.0.2: icmp_seq=3 ttl=64 time=0.369 ms
64 bytes from 10.0.0.2: icmp_seq=4 ttl=64 time=0.363 ms
64 bytes from 10.0.0.2: icmp_seq=5 ttl=64 time=0.366 ms

--- 10.0.0.2 ping statistics ---
5 packets transmitted, 5 received, 0% packet loss, time 4074ms
rtt min/avg/max/mdev = 0.363/0.427/0.660/0.116 ms

Step 5: Ping IP address 224.0.0.1 from DUT0:

admin@DUT0$ ping 224.0.0.1 count 1 size 56 timeout 1
Show output
PING 224.0.0.1 (224.0.0.1) 56(84) bytes of data.

--- 224.0.0.1 ping statistics ---
1 packets transmitted, 0 received, 100% packet loss, time 0ms

Step 6: Ping IP address 224.0.0.1 from DUT1:

admin@DUT1$ ping 224.0.0.1 count 1 size 56 timeout 1
Show output
PING 224.0.0.1 (224.0.0.1) 56(84) bytes of data.

--- 224.0.0.1 ping statistics ---
1 packets transmitted, 0 received, 100% packet loss, time 0ms

Step 7: Send arp ping from DUT0 to IP address 1.1.1.1:

admin@DUT0$ arping 1.1.1.1 interface eth0 timeout 5 count 1
Show output
ARPING 1.1.1.1 from 10.0.0.1 eth0
Sent 1 probes (1 broadcast(s))
Received 0 response(s)

Step 8: Send arp ping from DUT1 to IP address 1.1.1.1:

admin@DUT1$ arping 1.1.1.1 interface eth0 timeout 5 count 1
Show output
ARPING 1.1.1.1 from 10.0.0.2 eth0
Sent 1 probes (1 broadcast(s))
Received 0 response(s)

Note

Repeat the SNMP command above to check for new statistics (information may take some time to refresh).
