Definitions may combine these properties differently.
Numbers refer to source variants above. Each value is shown only for variants that define it. Notes below names come from selected MIB definitions.
| Value | Name and source notes | Source variants |
|---|---|---|
| 1 | broadcast | 1, 2 |
| 2 | nBMA | 1, 2 |
| 3 | ptp | 2 |
| 4 | ptp old value 3 | 1 |
| 8 | loopback new value | 1 |
| 16 | tunnel new value | 1 |
At least one MIB declaration places this object in a table row. A value belongs to a row instance; its suffix depends on the row's INDEX or AUGMENTS definition.
In CROUTE-MIB, the row index ipInterfaceAddr is declared as IpAddress. The IPv4 address is encoded as four numeric subidentifiers, one for each address octet. For example, a row with address 192.0.2.10 has the instance .1.3.6.1.4.1.81.31.1.2.1.4.192.0.2.10. Use an index value actually present on the device and permitted by its MIB. Other definitions can differ.

Replace the placeholders with your connection and authentication options. Available permissions and device support can differ from the MIB.
Properties come from available MIB definitions. Actual device support and access can differ. See source records below for original files and qualifications.
The displayed source records contain one distinct definition. Compare its source records.
