Snmpwalk-v 2c-c Pub_PCon9-CT 192.168.232.25 1.3.6.1.1.1.47.1.1.1.1.11.1

Or

Snmpwalk-v 2c-c Pub_PCon9-CT 192.168.232.25 1.3.6.1.4.1.9.3.6.3.0

# get device name

Snmpwalk-v 2c-c Pub_PCon9-CT 192.168.232.25 1.3.6.1.2.1.1.5.0

# the following is an example of obtaining the MAC address of the host connected to the second port of the switch (INTEGER: 2)

# # step 1 # #

Snmpwalk-v 2c-c Pub_PCon9-CT 192.168.232.25 1.3.6.1.1.17.4.3.1 | grep-w "INTEGER: 2"

Return the result:

SNMPv2-SMI::mib-2.17.4.3.1.2.0.7.233.63.136.173 = INTEGER: 2

# # step 2 # #

# get the bold word "0.7.233.63.136.173" from the return result of step 1 above, and execute the following command

Snmpwalk-v 2c-c Pub_PCon9-CT 192.168.232.25 1.3.6.1.1.17.4.3.1 | grep "0.7.233.63.136.173" | grep "mib-2.17.4.3.1.1"

Return the result:

SNMPv2-SMI::mib-2.17.4.3.1.1.0.7.233.63.136.173 = Hex-STRING: 00 07 E9 3F 88 AD

00 07 E9 3F 88 AD is the address of the host network card connected to the second port of the switch

# # step 3 # #

Snmpwalk-v 2c-c Pub_PCon9-CT 192.168.232.25 1.3.6.1.1.17.1.4.1.2 | grep-w "SNMPv2-SMI::mib-2.17.1.4.1.2.2" where the red 2 is INTEGER: 2 of step 1

Return the result:

SNMPv2-SMI::mib-2.17.1.4.1.2.2 = INTEGER: 2

The INTEGER: 2 obtained in step 3 is the corresponding IfIndex.
