Cisco 3560 switch interface traffic grabbing vbs scriptTo make it easy for you to view the traffic of the vswitch interface, the customer does not log on to the vswitch, and does not have any network management traffic statistics device. Simply write a vbs script, which is simple and usable. On error resume next dim wshellset WshShell = WScript. createObject ("WScript. shell ") WshShell. run "cmd" WshShell

Q: Are there any simple tools and methods? Run the script automatically on N or so cisco switches according to the script, and then return the result?Method 1: Download and modify the vswitch configuration file and upload it to N vswitches. Restart or copy start run.Method 2: Create a bat file under windows. The content in the file is the same as the command you used to telnet to the vswitch for modification, except that the IP address needs to be N t

Q: Are there any simple tools and methods? Do a script, automatically execute on a script in N-around Cisco switches, and then return the results? Method One, the switch configuration file download, modified and uploaded to the n-switch. Then restart or copy start run. Method Two, under Windows to build a bat file, the contents and you telnet to the

and continue to "keep calling". However, if host-d tries to send a frame to host-e within 20 seconds (assuming HOST-E has not already sent the packet), the frame floods all the switch links, because the Ee-ee-ee-ee-ee-ee MAC address is no longer in the Address table. table 6-8 shows that three switches converge in the new topology and the data traffic is also restored after the entry of address Ee-ee-ee-ee-ee-ee in the MAC address table. Table 6-8. B
