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. So enter the command: Router # delete sup-bootflash: s72033-pk9sv-mz.122-

message are correctIf a large number of messages are sent, the network bandwidth will be exhausted to form another Denial-of-Service attack.3. The client can specify the IP address at will.The client does not have to use the DHCP service. It can set IP addresses in a static way. If any,This will greatly increase the possibility of network IP address conflict.II. Introduction to DHCP Snooping TechnologyDHCP Snooping is a DHCP security feature. Cisco s

to say, after you set the password for level 1, you will be asked to enter the password next time you connect to the switch and enter K, this password is the password set for level 1. Level 15 is the privileged mode password that you enter after you enter the enable command. Step 2: Set the VLAN name. Because the four VLANs belong to different switches, the command for VLAN naming is VLAN 'vlan No. 'name' vlan name ', the following code configures VL
