The default gateway on host B should be Which option is the default switch port port-security violation mode? When in this mode, the switch will automatically force the switchport into an error disabled err-disable state when a violation occurs. While in this state, the switchport forwards no traffic. The switchport can be brought out of this error disabled state by issuing the errdisable recovery cause CLI command or by disabling and re-enabling the switchport.

By default, how many MAC addresses are permitted to be learned on a switch port with port security enabled? If the maximum number of MAC addresses is reached, when another MAC address attempting to access the port a security violation occurs. Which set of commands is recommended to prevent the use of a hub in the access layer?

SWITCH 300-115

Select the action that results from executing these commands: Switch config-if switchport port-security Switch config-if switchport port-security mac-address sticky A. A dynamically learned MAC address is saved in the startup-configuration file. A dynamically learned MAC address is saved in the running-configuration file. Statically configured MAC addresses are saved in the startup-configuration file if frames from that address are received. Statically configured MAC addresses are saved in the running-configuration file if frames from that address are received.

Refer to the exhibit. What two functions will occur when this frame is received by Switch? Choose two. In this case, the switch will dynamically learn the MAC address Choose two A. If any other device is detected, the port is to drop frames from this device. Which two of these changes are necessary for SwitchA to meet the requirements?

To enable Port security feature, we must enable it on that interface first with the command:. Which condition does the err-disabled status indicate on an Ethernet interface? Port security work on host port. In order to configure port security we need to set it as host port. It could be done easily by switchport mode access command. According to our requirements we can limit the number hosts that can be associated with an interface.

We can set this limit anywhere from 1 to Maximum number of devices that can be associated with the interface is By default it is set to 1. This is the most secure method but requires a lot of manual works. In dynamic method we use sticky feature that allows interface to learn mac address automatically.

Interface will learn mac addresses until it reaches maximum number of allowed hosts. We need to specify what action; it should take in security violation. Three possible modes are available:.

Categories

Protect : - This mode will only work with sticky option. In this mode frames from non-allowed address would be dropped. It will not make log entry for dropped frames. Interface will learn address until it reach maximum allowed number. Any additionally learned addresses would be dropped while keeping interface operational.

Restrict : - In restrict mode frames from non-allowed address would be dropped. But in this mode, switch will make a log entry and generate a security violation alert. Shutdown : - In this mode switch will generate the violation alert and disable the port. Only way to re-enable the port is to manually enter no shutdown command. This is the default violation mode.

We used dynamic address learning feature of interface. You can check MAC Address table for currently associated address.

Switch learns mac address from incoming frames. In our scenario we have connectivity between server and pc. We can use this utility to generate frames from PC0. Use ping command to generate frames.

One interesting thing that you may notice here is the type. This is the magic of sticky option, which we used with port security command. Sticky option automatically converts dynamically learned address in static address. In our topology we have one additional PC. Assume that, this is the cracker's PC.

To gain unauthorized access in network he unplugged the Ethernet cable from pc PC0 and plugged in his pc PC1. Click red X button on the right hand partition of packet tracer window and place the X over the connection between Switch and PC0.
