What is s5EnPortLinkStatus?

Reports whether this port is seeing link (on/off applies to 10BASE-T and fiber ports; other(1) is returned for AUI), the first thing to check when a port that should be up isn't passing traffic.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.45.1.6.6.1.1.1.5
snmpwalk -v2c -c public <target> S5-ETHERNET-COMMON-MIB::s5EnPortLinkStatus

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.45.1.6.6.1.1.1.5.1
snmpget -v2c -c public <target> S5-ETHERNET-COMMON-MIB::s5EnPortLinkStatus.1
