dErpsInstOperPort0IfIdx

Module: DLINKSW-ERPS-MIB

OID (symbolic): DLINKSW-ERPS-MIB::dErpsInstOperPort0IfIdx

OID (numeric): 1.3.6.1.4.1.171.26.78.1.5.1.13

Node type: OBJECT-TYPE

Type: InterfaceIndexOrZero

Access: read-only

Description: This object indicates the ifIndex of the operational first ring port of the physical ring. The value of administrative port0 inherits dErpsEtherRingAdminPort0IfIdx of physical ring to which the instance belongs. The special value of zero indicates the operational port0 is not available.

What is dErpsInstOperPort0IfIdx?

Reports the ifIndex of the operationally active first ring port, normally inherited from the physical ring's dErpsEtherRingAdminPort0IfIdx; zero means it is unavailable. Admins use it to confirm which physical interface is actually serving as ring port 0 right now.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.171.26.78.1.5.1.13
snmpwalk -v2c -c public <target> DLINKSW-ERPS-MIB::dErpsInstOperPort0IfIdx

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.171.26.78.1.5.1.13.1
snmpget -v2c -c public <target> DLINKSW-ERPS-MIB::dErpsInstOperPort0IfIdx.1
