Hi,

I'm already struggling couple of days with the topic so i need your help :)

 

Lets start with the topology description

 

ROUTER 1

 -> ROUTER2 (access point)

 -> ROUTER3 (access point)

 -> SG108PE

     -> EAP113 (outdoor wifi repeater) powered via PoE, extends router 1 SSID

 

Identified strange behaviour:

1) whole network is unavalble when SG108PE is down (fe. restart)

2) random network unavaibility ~10-20s (started when switch was installed)

3) SG108PE v2 identifiesas SG105E v4 when accessed both via webpage and Easy Smart Configuration Utility:

    A) once connected directly Laptop - SG108PE and after Factory Reset switch identifies as SG108PE with 192.168.0.1 - swich able to perform FW upgrade, curent FW: en_1.0.1_[20191204-rel.71847

    B) once connected to SG108PE via LAN identifies as SG105E v4 with 192.168.0.1 (visible via Easy Smart Configuration Utility) - not able to perform FW upgrade as image verification fails (I assume HW mismatch during check)

    C) not able to configure all 8 ports as 105E supports only 5 ports

    D) 108PE and 105E identifies with different MAC Address.

 

 

I assume random drops might be connected to STP beeing confused about 108PE and 105E both addresing the same factory IP.

Factory subnet 192.168.0.X

My subnet 192.168.1.X

Sometimes when i do the scan with Easy Smart Configuration Utility both records for 108 and 105 are visible which is odd as it's only one sad confused device.

 

 

Any ideas?

Sadly, the device is out of guarnatee as i recently found it in the drawer looking for something to per the accesspoint. Not sure about his past :)
