"Feature" request: Improve discovery (LLDP) compatibility with TP-Link

RouterOS RouterOS beta
1

We use TP-Link JetStream switches, and they appear to be sending NUL-padded device name (identity) field in LLDP. This is even with latest switch firmware; newer models only add more padding (presumably to support longer switch names). Because of this, the default tabular view of /ip/neighbor/print becomes useless as the “IDENTITY” column doesn’t fit at all (and RouterOS just omits it instead of truncating).

It would be nice if RouterOS could ignore \00 NUL padding for compatibility with these devices.

While Mikrotik are looking into this :slight_smile:

I have a Xirrus AP, the Mikrotik seems to see it only with LLDP, while the Xirrus is also sending CDP.
Also, the Xirrus provides a system description entry that is only visible from the CLI, not from winbox
or webfig (Not sure how it should be displayed, perhaps like a comment on a line by itself as it is quite big)
