WAN Probz

[anand]

Hi,

currently i am facing a probs in WAN connection,

PC A(170.1.97.27/24) is connected to PC B(170.1.97.51/24) via RAD Ethernet Modem( 1 modem in PC A & other in PC B side)

PC B(170.1.97.51/24) is connected on Switch A(located in 2nd Floor)

Switch A is connected to Switch B(located in 1st floor)

in Switch B, all the WAN Routers are connected.(location like X,Y,Z)

now the problem is, when Switch A is connected to Switch B,Router A(170.1.32.2/24)which is connected in Switch B is not pinging, becuase of this, location X(170.1.81.1/24) & Y(170.1.82.1/24) cannot be reached by any one of Switch B users, where as location Z(170.1.88.1/24) can be reached. but when i remove the cable which is connecting from Switch A to Switch B, Router A can ping X Y & Z.

what is the problem & where the problem is residing.

Hello,

is your switch B doing any routing ? Can you post the configuration of Switch B ?

Hi,

the problem has been solved by me itself by just setting the "no logging console" just because of this, the CPU process is getting high & thats the reason it hangs for some times till it flushes out the message.

If you are having this problem, then you should check if you have any debug's going... do a "show debug".. and maybe a "undebug all"? :)

There shouldn't be too many messages going to the console unless you have specifically set some debug-levels or there are some problems in the system/setup... and running debug for a long time in a production system is not a good idea..

yeah i know that setting the debugging ON will increase the CPU usage, but havn't come across such problem till now, actually this was happing in remote end, so i told him to capture the console, only after seeing "CPUHOG & LOGGER_FLUSHED"message, i came to the CPU usage is very high, so that time i had i realised that "logger console" command was enabled & when i disabled the problem has been solved.
