Update interface descriptions



Hi, In existing setup interfaces are represented in the format

(001) ethernet0/0 or (001) Link to xx

It seems it displays interface name when there is no interface description configured on the device.

I understand the digit representation is some internal port allocation which unfortunately is not very meaningful and helpful to be there.

Can I change this representation to show as:

ethernet0/0 Link to xx when there is interface description configured on the interface


ethernet0/0 when interface description has not been setup

...without losing historical data?

My second question. Currently interface descriptions have been picked up by the auto discovery and show in PRTG. They have been changed on the actual devices though. Can I update PRTG to reflect the new interface descriptions without losing historical data for these devices?

In the device settings, please go to SNMP Compatibility Options.

For the Port Name Template try the available settings

[port] [ifalias] [ifdescr]

to get better interface naming.

Changed interface names on the device can not yet be updated in PRTG automatically. It might be possible in the future.

Is this on the roadmap at all? We have a network where port names can change periodically. It'd be immensely helpful to be able to set it to re-scan interfaces and rename them on auto-discovery.
