<![CDATA[How long will LLDP-data be stored/cached on a node?]]>We changed the connection between two LLDP-capable switches:

First Switch1-Port7 connected to Switch2-Port1,
Then we changed to Switch1-Port2 connected to Switch2-Port8.

Now in [Object Details] - [Interfaces] of node Switch1 I can see Switch2 connected to Port 2 AND 7. the same MAC and the same IP-Addresse and Peer Discovery on both interfaces = LLDP. The same on Switch2.
When I look at [Tools] - [Info] - [Topology Table (LLDP)] there is only the new connection.

Is there something like a Lease Time for LLDP information?

No old topology info anymore. Thanks Victor.

Now it should correctly remove outdated information (it does on my tests).

Best regards,

I was able to reproduce this problem on my system and found the bug causing it. I'll fix it till next release.

Best regards,
Victor

Beside the out-dated LLDP topology information I also see out-dated FDB information.

The same as I described in my first post. Which information do you need for further troubleshooting? I also see a lot of SYS_IF_PEER_CHANGED events from different nodes but nothing has changed in topology.

I deleted one switch and re-add then run the topology poll the link is gone.

supposedly I've found the problem. I've made necessary changes in 1.2.16. Please let me know if your problem will be solved after upgrade.

Best regards,
Victor

Our Peer Node information (LLDP) are still not updated.

What i do as a workaround, is to delete the node and re-add it and the run a topology discovery poll.

But the old link information stays on both switches for ever. So it's maybe a bug.

You can also do manual topology poll via Poll -> Topology menu on node. If incorrect link information stays more than topology polling interval then it's a bug.

Victor
