any idea why Hub will cause the network slow ? based on the attachment. i found 1 hub (Cisco_Micro_Hub)is connected to my network but how could block this ?
this setup really drive me crazy .... From the Dist_1 i detected 1 micro_hub connected to the same port for Sw1 (Fa0/24). so, when i show cdp nei from Sw1 i saw the hub is connected to the same port (Fa4/31) with the Dist_1.
any idea ? thanks.
