Dear Forum Members,
Recently I am noticing high CPU usage (100%) on my CCR1072. My scenario
7 Firewall filter rules
11 Mangle rules
10 Queue tree
No NAT
No Connection Tracking
BGP
LACP 30gbps (803.ad) with mikrotik CRS328 switch
SNMP (NMS+Tree graphing)
When the traffic is ~10gbps CPU is around 7-8% but when peak hour reached, traffic will go up to 17-18gbps then CPU hits 100%. Also, goes back to 20-30% after disabling mangle rules. What can be workaround to get these queue tree graphed?
I am experiencing the same issue on a CCR1072, the problem has started when I have added 1 LACP
I am running RouterOS v7.16 and I do not have any Mangle rules or Queue Tree configured at all.
Despite this, when traffic increases above ~15–18 Gbps, the CPU usage reaches 100%.
At lower traffic levels the CPU usage is normal and stable.
This suggests that the problem is not only related to mangle or queue processing, but more likely caused by:
CCR1072 architectural limitations at high PPS rates
Software-based packet processing in RouterOS v7
Lack of L3 hardware offloading on this model
Possibly additional load from SNMP polling / traffic graphing during peak hours
Since the CCR1072 has no switch ASIC and all forwarding is done by the CPU, it seems to hit a scalability limit at higher throughput regardless of configuration.
Have you managed to find a solution or workaround for this issue?
