When we think of connectivity in a network, the router is probably the first device that comes to mind, but switches play a vital role in enabling network devices to communicate. Switches can take incoming/outgoing traffic and pass it onward toward its final destination.
How to secure Cisco switch ports?
One way to secure ports is by implementing a feature called port security. Cisco port security limits the number of valid MAC addresses allowed on a port. The MAC addresses of legitimate devices are allowed access, while other MAC addresses are denied.
What does a network engineer do when you take a switch out of the box?
When you take a new switch out of the box, the first thing the network engineer does is secure the switch and assign it an IP address, subnet mask, and default gateway so the switch can be managed from a remote location. Learning the different methods used to secure a switch is important.
How to delete RSA key pair?
To delete the RSA key pair, use the crypto key zeroize rsa global configuration mode command. After the RSA key pair is deleted, the SSH server is automatically disabled.
How to protect network from unauthorized access?
A simple method that many administrators use to help secure the network from unauthorized access is to disable all unused ports on a switch. For example, if a Catalyst 2960 switch has 24 ports and there are three Fast Ethernet connections in use, it is good practice to disable the 21 unused ports. Navigate to each unused port and issue the Cisco IOS shutdown command. If a port later on needs to be reactivated, it can be enabled with the no shutdown command. Figure 2-23 shows partial output for this configuration.
What port is sticky secure MAC address?
Table 2-12 shows the commands needed to enable sticky secure MAC addresses for port security on Fast Ethernet port 0/19 of switch S1. As stated earlier, a specific maximum number of secure MAC addresses can be manually configured. In this example, the Cisco IOS command syntax is used to set the maximum number of MAC addresses to 50 for port 0/19. The violation mode is set to the default mode of shutdown.
Does basic switch security stop malicious attacks?
Basic switch security does not stop malicious attacks. Security is a layered process that is essentially never complete. The more aware networking professionals within an organization are regarding security attacks and the dangers they pose, the better. Some types of security attacks are described here, but the details of how some of these attacks work are beyond the scope of this course. More detailed information is found in the CCNA WAN Protocols course and the CCNA Security course.
Can you disable CDP on a port?
It is recommended that you disable the use of CDP on devices or ports that do not need to use it by using the no cdp run global configuration mode command. CDP can be disabled on a per port basis.
How to prepare a switch for remote management?
To prepare a switch for remote management access, the switch must be configured with an IP address and a subnet mask. Keep in mind that to manage the switch from a remote network, the switch must be configured with a default gateway. This is very similar to configuring the IP address information on host devices. In Figure 2-4, the switch virtual interface (SVI) on S1 should be assigned an IP address. The SVI is a virtual interface, not a physical port on the switch.
How to configure a switch as a default gateway?
To configure the default gateway for the switch, use the ip default-gateway command. Enter the IP address of the default gateway. The default gateway is the IP address of the router interface to which the switch connects. Use the following command to backup the configuration: copy running-config startup-config.
How to tell if a port is PoE?
If PoE is supported, a PoE mode LED will be present. If the LED is off, it indicates the PoE mode is not selected and none of the ports have been denied power or placed in a fault condition. If the LED is blinking amber, the PoE mode is not selected but at least one of the ports has been denied power, or has a PoE fault. If the LED is green, it indicates the PoE mode is selected and the port LEDs will display colors with different meanings. If the port LED is off, PoE is off. If the port LED is green, PoE is being provided to a device. If the port LED is alternating green-amber, PoE is denied because providing power to the powered device will exceed the switch power capacity. If the LED is blinking amber, PoE is off due to a fault. If the LED is amber, PoE for the port has been disabled .
