addition to quickly locating the physical location of the suspect device, there is a means to gather evidence as soon as possible. It is not possible to place a network analysis or intrusion detection device next to each access layer switch, or to carry an analyzer to the wiring compartment when suspicious traffic is found. With the above analysis, let's look at how to use the catalyst function to meet these needs! detects suspicious traffic Cat6

Take the Cisco 2950 vswitch as an example. log on to the vswitch and enter the management password to enter the configuration mode. Then, run the following command: Switch # config Terminal # Enter the Configuration Mode Switch (config) # interface fastethernet 0/1 # Enter the specific port configuration mode Switch (config-If) # switchport port-secruity # Configure port security mode Switch (config-If) switchport port-security Mac-address MAC (MAC address of the host) (Config-If) No switchport

each group. In this syntax: Group_by_expression specifies certain columns. The values of these columns determine the baseline for grouping rows. • Unless a single column is specified in the group by clause, a single result cannot be selected even if a GROUP function is included in the SELECT clause. If the list of columns is not included in the group by clause, an error message is returned. • By Using the WHERE clause, You can exclude certain rows before dividing rows into multiple groups. • Co
