TP-link T2600G-28TS not polling ports

    Description

      When I add a TP-Link T2600G-28TS switch, the discovery module, finds all the ports, but, after the first run of the poller, all the ports are marked as "DELETED", so they won't be polled anymore.

      Every 6 hours (when the discovery module runs), same thing happens: ports are discovered, but deleted after the first execution of the poller.

      I have other TP-Link switches, but they are working fine.

      Attached you can find execution of:

      ./discovery.php -d -m sensors -h XX

      and 

      ./discovery.php -d -m os -h XX

          No problem.
          As I remember, this is common trouble for TP-Link switches.

          You are right. I had to increase the timeout. Sound strange, because other devices on the same place are not suffering of this issue. Probably this switch respond very slowly...

          Sorry for opening the issue.

          But as I see in your discovery debug, this is device or network trouble:

          CMD[/usr/bin/snmpget -v2c -c *** -Pu -OQUst -m SNMPv2-MIB -M /opt/observium/mibs/rfc:/opt/observium/mibs/net-snmp 'udp':'sw01.italia1.gs.leaf.space':'161' sysObjectID.0 sysUpTime.0]
          		 
          STDOUT[
          		 
           
          		 
          ]
          		 
          STDERR[
          		 
          Timeout: No Response from udp:sw01.italia1.gs.leaf.space:161.
          		 
          ]
          		 
          SNMP STATUS[FALSE]

          try increase device snmp timeout setting (in device -> edit -> SNMP tab).

          please attach debug for:

          ./discovery.php -d -m ports -h <device>

          and rigth after this, for poller too:

          ./poller.php -d -m ports -h <device>
