What is s5EnPStatSourceAddrChngs?

Counts how many times the 'last source address' seen on this port has changed, a useful signal for detecting a port that's unexpectedly seeing traffic from multiple different devices (e.g. an unmanaged hub or a MAC spoofing situation).

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.45.1.6.6.2.2.1.2
snmpwalk -v2c -c public <target> S5-ETHERNET-COMMON-MIB::s5EnPStatSourceAddrChngs

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.45.1.6.6.2.2.1.2.1
snmpget -v2c -c public <target> S5-ETHERNET-COMMON-MIB::s5EnPStatSourceAddrChngs.1
