[MS Switch] CDP/LLDP how working

[Th1b0plz]

Hello,

I'm not find information accurate about protocol CDP / LLDP, how working this on meraki switch

- what is the actualisation time after a
new connection ?

- And the hold time for an old discover disappears on a port ?

- Possible to force actualisation manually ?

Thanks for information.

I believe those are inner workings of the software on the switches themselves.  Not something we would know.

The only info I do know is:
LLDP frames are sent every 30 seconds with a ttl of 120 seconds
CDP frames are sent every 60 seconds with a ttl of 180 seconds

The switches should catch on quite quickly if a new entry comes up in the switch.  But they do seem to keep old entries on for a while and the change is not reflected on the dashboard immediately.

Thanks for your answer.

indeed the update during a new connection is quite fast

on the other hand the disappearance of an old connection seems to take several hours but how exactly

that is the question 🙂
