since 23 days I get the SNMP error # 223 on some switchports on a Cisco Switch. SNMP works properly on about 150 switchports, but around 20 ports cant be monitored since the 29th of march. Before this date they also were scanned without any issues. Could you maybe help me with this issue? The ports are connected and everything is fine, only the monitoring is broken. Its just annoying in the error overview to have all these ports (also on some other switches) shown up.
