# <a name="about">About</a>:
Librenms can interpret, display and group certain additional information on ports.
For this a small `bash` script is supplied in `librenms/scripts` called `ifAlias`.
<a name="setup">Setup</a>:
This requires a little bit of setup on the monitored Server (Not the server running librenms!):
* Add `ifAlias` from `/path/to/librenms/scripts/` or download it from [here](#source) to the Server and make
it executeable `chmod +x /path/to/ifAlias`
* Add to `snmpd.conf` something like:
``pass .1.3.6.1.2.1.31.1.1.1.18 /path/to/ifAlias``
* Restart your `net-snmpd`
There are no changes to be made or additions to insteall for the polling librenms.
Now you can set up your [keywords](#keywords) in your `/etc/network/interfaces`
``//Add more distributions than just Debian based``
# <a name="keywords">Keywords</a>:
See [examples](#examples) for formats.
* <a name="type-keywords">Type-keywords</a>:
* `Cust` - Customer
* `Transit` - Transit link
* `Peering` - Peering link
* `Core` - Infrastructure link (non-customer)
* `Server` - Server link (non-customer)
* <a name="info-keywords">Info-keywords</a>:
* `()` contains a note
* `{}` contains *your* circuit id
* `[]` contains the service type or speed
