I would like to know what debugging tools exist in the IOS of cisco catalysts as well as for a 6509?
I am sitting with a problem where there are 3 floors in the same building (admin building). Each floor has 3 switches. So there's a total of 9 switches. These switches are connected with fibre to the head office, which is about 5 minutes walking distance from the admin building. These fibre cables then connect to a 6509 gig blade. This 6509 then connects to a cisco router as the gateway. The head office use the exact same 6509 and gateway router, but head office is not complaining about slow response.
Basically what happens is intermittently the users on all floors in admin building will complain there's a very slow response to all their applications. This occurs like once a week or so but then it will be throughout the day that they will have slow connectivity and then fast connectivity etc.
I would like to know if there is a debugging tool in the IOS for the switches as well as for the 6509 in order to try and nail the problem?
