Hi, I am also facing this issue of e410 going offline from cloud and also not pingable from the same network. I have upgraded all the e410 to latest 4.2.3.1-r9 firmware. Trunk link is passed to the AP and AP is in Native VLAN meaning AP is getting ip from Native VLAN. The problem is AP automatically goes offline from the cloud and came back later

Hi,

We have mostly seen this issue relate to local network problems.

  1. The AP keeps sending ping messages to the cloud. If it misses consecutive PONG responses, it declares the connectivity down.
  2. Mostly, it relates to local network issues such as momentary packet storms due to heavy BUM traffic, network loops, or ARP poisoning.

As you mentioned, the AP is also not reachable on the local network. We request that you check the above points. We assume there are no power-related issues on the infrastructure side.

If you are still observing the issue, please share the AP tech dump.

Hi Sanjay thank your for replying. I have the following configuration for my network.

  1. Native vlan is 99, and other few vlans were passed to AP in Trunk from a Switch.
  2. The AP resides on VLAN 99.
  3. The AP came online in cloud for few internal and configuration is not in sync.
  4. When again i try to sync the configuration for few minutes the AP broadcast the SSIDs and works fine for few minutes, then automatically the AP reboots and came in cloud after reboot,
  5. After rebooting the configuration is again not in sync and it doesnot broadcast the SSID.

Hi, this indicates that the new change you are trying to push is making the ap to lose its connectivity.
Please verify the new configuration you are trying to push.
AP auto heal and try to reboot with old working configuration. This AP auto recovery is to avoid any service impact.

Hallo, in einer WLAN Installation ist das genauso. Es schalten die E410 Ap´s auf offline. Einige Zeit später, gehen sie offline. Einige sind auch nicht synchron. Dann wieder alles Online und synchron.
In einer anderem Netzwerk, was genauso aufgebaut ist, gibt es keine Probleme.

Alle AP´s und Switche sind Firmware technisch auf dem neusten Stand.

Wer kann helfen. Benötige Hilfe Zeitnah.

LG René

Hi,
kindly follow this checklist,
1.The AP management vlan is allowed in AP ethernet ports.
2. ip ‘request option all’ option must be enabled on ap management interface.
3. All in between switches are allowed with AP management vlan.
4. Identify the new change u are adding to ap group, country code change? setting power out of limit, setting channels which are not available.

If that does not resolved then ,
please share me AP tech dump & Export AP group configuration from AP group profile. to compare.
