Scenario

In this activity, two switches are completely configured. On a third switch, you are responsible for assigning IP addressing to the Switch Virtual Interface, configuring VLANs, assigning VLANs to interfaces, configuring trunking, and performing basic switch security.

Requirements

S1 and S2 are fully configured. You cannot access these switches. You are responsible for configuring S3 with the following requirements:

·         IP addressing and default gateway configuration, according to the Addressing Table.

·         Create, name, and assign VLANs according to the VLANs and Port Assignment Table.

·         Assign the native VLAN 99 to the trunk port and disable DTP.

·         Restrict the trunk to only allow VLANs 10, 20, 30, 88, and 99.

·         Use VLAN 99 as the native VLAN on the trunk ports.

·         Configure basic switch security on S1.

-       Encrypted secret password of itsasecret

-       Console password of letmein

-       VTY password of c1$c0 (where 0 is the number zero)

-       Encrypted plain text passwords

-       MOTD banner with the message Authorized Access Only!!

-       Disable unused ports.

·         Configure port security on F0/6.

-       Only two unique devices are allowed to access the port.

-       Learned MACs are added to the running configuration.

-       Secure the interface so that a notification is sent when there is a violation, but the port is not disabled.

·         Verify the PCs in the same VLAN can now ping each other.
