1. Explain the significance of each of the following types of VLAN: Data, Management, Native, and Blackhole. Explain where each type of VLAN fits into a LAN network. In addition, what is the default VLAN on a Cisco switch for Data, Management, and Native frames? Justify your answer Solution There are different types of VLANs. The type of network traffic they carry defines a particular type of VLAN and others derive their names due to the type or a specific function the VLAN performs. The following describes common VLAN: A data VLAN also known as a user VLAN is configured to carry only user-generatedtraffic. The importance of separating user data from other type of VLAN is proper switchmanagement and control. A Management VLAN is any VLAN you configure to access the managementcapabilities of a switch. A Native VLAN is assigned to an 802.1Q trunk port. An 802.1Q trunk port supportstraffic coming from many VLANs as well as traffic that do not come from a VLAN. The802.1Q trunk port places untagged traffic (traffic that does not come from a VLAN) onthe native VLAN. A Blackhole VLAN is a term used for a vlan configured for unused ports. It’s a securitypractice, whereby you create a vlan that has no route, or no default gateway to othernetworks within your organization, or to the internet. The Default VLAN is simply the VLAN which all Access Ports are assigned to until they are explicitly placed in another VLAN. In the case of Cisco switches (and most other Vendors), the Default VLAN is usually VLAN 1. Typically, this VLAN is only relevant on an Access port, which is a port that sends and expects to receive traffic without a VLAN tag..
