    Hello,

    According to Document 40367 I’m trying to get the MAC address connected to a specified port.

    The first stage was:
    snmpwalk 192.168.0.254 -Os -c public -v 2c .1.3.6.1.2.1.17.4.3.1.1

    But the response was:
    mib-2.17.4.3.1.1 = No Such Instance currently exists at this OID

    The switch details are:

    What is the reason the OID is not responding ?
