Hi, I have a very unique problems that I am unable to solve as I have never seen the symptoms before + there are no errors on the affected equipment.
The layout of the equipments are as such
other equipment <--> 2911 Router <--> Ether-Switch/3925 Router <--> 7206 <--> Internet
During certain times at night, the 2911 exhibits cpu load, high packet loss and an increase in bandwidth of at least twice it's normal amount. this results in packet loss in all the other equipment. I am attempting to locate who was demanding such a high burst but so far the graphs display normal rates for all the other equipment.
Because the 2911 demands an increase from the 7206, the 7206 is able to accomodate this as it still has balance BUT my other equipment that are connected to the 7206 takes a drop in bandwidth as well. the graph shows that when the 7206 bursts higher, the rest of my other links take a slight drop in bandwidth.
Also, the graph from Ether-switch to 2911 indicates the bandwidth hike BUT the graph from 2911 to ether-switch does not display the same thing as due to the cpu load, the data is somehow not captured properly.
The 2911 has firmware c2900-universalk9-mz.SPA.150-1.M1.bin, no logs to indicate any errors, CPU processes appear normal. is there anything I can do to resolve this issue?
