server and the client are in the same network segment and are not DHCP relay agents, for Cisco's DHCP In the case of a server, if a request packet with Option82 is received, it is considered a request message from a DHCP relay agent, and the Giaddr field of the message is checked, but because it belongs to the same network segment, the field is 0.0.0.0 DHCP. The server will consider an illegal address, and this message will be discarded, causing the client to obtain no IP address(iv)

Calculate the bandwidth of the backboard of a Cisco switch. It is the maximum amount of data that can be transferred between the vswitch interface processor, interface card, and data bus. The higher the bandwidth of the backboard of A vswitch, the stronger the ability to process data, but the design cost will also rise. Www.2cto.com but how can we check whether the bandwidth of A vswitch is sufficient? Obvi

After the FLASH space is insufficient, I specially query the hardware configuration of the 6509 core device. The default Flash of the 6509 standard configuration is 64 MB, and the standard IOS size is 32.1 MB, the IOS 12.2 (17a) SX version to be upgraded has a size of 40.6 MB. In this case, it seems that the space is insufficient. However, this problem is well solved. The original IOS in Flash is deleted and then uploaded.
