During Interface Discovery, OpManager queries the ifName (.1.3.6.1.2.1.31.1.1.1.1), ifDescr (.1.3.6.1.2.1.2.2.1.2) and ifAlias (.1.3.6.1.2.1.31.1.1.1.18) OIDs and constructs the Interface DisplayName as mentioned in the table below.
| IfDescription | IfAlias | IfName | Interface Display Name |
|---|---|---|---|
| Not null | Not null | - (Any value) | IFDescription-IfAlias |
| Not null | Null | Not null | IFDescription-IfName |
| Not null | Null | Null | IFDescription |
| Null | Not null | Not null | ifName-ifAlias |
| Null | Not null | Not null | IfName |
| Null | Null | Null | - |
p.s: The priority is from Top to Bottom.
Example 1:
ifDescription - Software Loopback Interface 1
ifAlias - Loopback Pseudo-Interface 1
ifName - loopback_1
Interface Display name: Software Loopback Interface 1-Loopback Pseudo-Interface 1
Example 2:
ifDescription - Software Loopback Interface 1
ifAlias - NULL (or) EMPTY
ifName - loopback_1
Interface Display name: Software Loopback Interface 1-loopback_1
Example 3:
ifDescription - NULL (or) EMPTY
ifAlias - Loopback Pseudo-Interface 1
ifName - loopback_1
Interface Display name: loopback_1-Loopback Pseudo-Interface 1
