Yes. In both cases vlan attached to bridge, no IPs on bridge. Unknown traffic could pass thru that vlan, like PPPoE or any other non-IP or broadcast/multicast. Any traffic should be limited by that queue.
Is that vlan attached to switch / bridge?
So why we have issues only with monitoring SNMP supporting devices and no issues using RouterOS API? Sure it is a same amount of data.Network monitoring IS NOT a light task
Any news? Is it works for you?I will try these, thank you very much for your helpDid you try SNMP V2c instead of V1 on the same device? Did you try Vacuum-db?
