Metro 1500 series with 100% CPU utilization

hi,

our client has 4 Metro 1500 series, all units have utilized 100% of the CPU. Is this a normal behavior of Metro 1500?

Re: Metro 1500 series with 100% CPU utilization

This configuration issue could have caused the switch to generate a lot of TCNs which got to the STP root switch, that I guess it is the 4k switch, and then, for each TCN the whole STP topology needs to reconverge causing a lot of traffic, and as the STP TCNs are analyzed by the CPU, this could caused the CPU utilization to go up. Or IP SNMP causes high CPU utilization.
