ZTP "LLDP synchronization" error

[jeronimo]

We have an 5320 (VOSS 8.8.1.0) which doesn't onboard into XIQ-SE 22.9 properly.
It shows up in "Discovered" pane of XIQ-SE, and after Configuring it, it shows "ZTP+ Use Discovered IP Error"

On the switch it says

2023-12-15 15:21:43,616:DEBUG:MainThread:ccsm_logger:send_message.987:: HTTP <Response [412]>
DATA:

"action": "PUT",

}

Just for reference in case someone else experiences this.

Turns out the actual problem was that ZTP+ CONFIG REQUEST sent from the switch looked messed up (it did not give its gateway or dns servers and showed management=false)

"networkAddress" : "192.168.88.18",
"networkPrefixLength" : 24,
"networkDefaultGateway" : "",
"dnsServer" : "",
"dnsServers" : [ ],
"dnsSearchSuffixes" : [ ],
"vrfId" : 0,
"domainName" : "",
"management" : false,

The solution was:

boot config flags factorydefaults zero-touch

Since this was a switch we got for test purposes (from Extreme), there must have been sth left on this switch from the guys previously using it (I suppose the test switches are in a rotating pool).

UPDATE

Apparently that was not the problem after all. The switch was working again but exhibited the same behavior when trying to onboard it using Fabric Extend, which we also did initially.  Apparently that breaks the ZTP process (permanently, unless factory reset or other unknown remedy). You have to use a normal onboarding VLAN and then later apply some Fabric Extend configuration.

For the XIQ-SE side of things please consider upgrading to a later release. 22.09 now falls outside our rolling 12-month support window with the release of 23.11.10 last month.

The above error suggests that the ZTP setting for "Use Discovered" is not set up properly or the Site Precedence may be set for something other than default "IP Range, LLDP". If XIQ-SE times out waiting to learn LLDP information from the device then it attempts to learn from the MGMT interface.

If you continue to have this condition consider opening a case with the XIQ-SE support team with ZTP+ diagnostics enabled (Administration -> Diagnostics -> Server -> Server Diagnostics -> ZTP+ -> Verbose. Ok.)
