What are two characteristics of VLAN1 in a default switch configuration?
VLAN 1 is the management VLAN. All switch ports are members of VLAN1.
Why would packets from the router or hosts fail when trying to reach the switch management interfaces if the native VLAN were left in default?
The native VLAN is untagged. If the VLAN 99 traffic to the router is untagged (as it would be, because that is native on the switches), the router cannot interpret the data because there is no VLAN information in the header as expected. In turn, the router tags all VLAN 99 traffic outbound, and leaves VLAN 1 data untagged, so the switches are unable to correctly interpret either. VLAN traffic to the other VLANs should not be affected by the assignment of the native VLAN.
What does VLAN stand for?
A VLAN is a virtual LAN. In technical terms, a VLAN is a broadcast domain created by switches. Normally, it is a router creating that broadcast domain. With VLANs, a switch can create the broadcast domain. This works by, you, the administrator, putting some switch ports in a VLAN other than 1, the default VLAN. All ports in a single VLAN are in a single broadcast domain. Because switches can talk to each other, some ports on switch A can be in VLAN 10 and other ports on switch B can be in VLAN 10. Broadcasts between these devices will not be seen on any other port in any other VLAN, other than 10. However, these devices can all communicate because they are on the same VLAN. Without additional configuration, they would not be able to communicate with any other devices, not in their VLAN.
What two methods avoid unintentional VLAN database corruption when adding a new switch?
1) reset the revision number before installing. 2) have a backup switch with existing VLAN data.
How do you create VLAN step-by-step?
AnswerVLANs are created on Layer 2 switches to control broadcasts and enforce the use of a Layer 3 device for communications. Each VLAN is created in the local switch's database for use. If a VLAN is not known to a switch, that switch cannot transfer traffic across any of its ports for that VLAN. VLANs are created by number, and there are two ranges of usable VLAN numbers (normal range 1-1000 and extended range 1025-4096). When a VLAN is created, you can also give it certain attributes such as a VLAN name, VLAN type, and its operational state. To create a VLAN, use the following steps.1) Configure VTP. VTP is a protocol used by Cisco switches to maintain a consistent database between switches for trunking purposes. VTP is not required to create VLANs; however, Cisco has set it up to act as a conduit for VLAN configuration between switches as a default to make administration of VLANs easier. Because of this, you must first either configure VTP with a domain name or disable VTP on the switch.2) Create the VLAN. VLANs are created by number. The two ranges of VLANs are as follows: The standard range consists of VLANs 1 to 1000. The extended range consists of VLANs 1025 to 4096. Extended VLANs are currently supported only on switches running COS software version 6.1 or greater. When you create a VLAN, you have many options to consider. Many options are valid only for FDDI and Token Ring VLANs. Some of the items configured deal with options, such as private VLANs, which are discussed in other sections in this book. VLANs are created using the set vlan command for COS devices or with the vlan command in vlan database mode for IOS switches.
Can STP be configured on an HP server?
Configuring Standard STP Parameters STP is disabled by default on Routing Switches. By default, each port-based VLAN on an HP device runs a separate spanning tree (a separate instance of STP). An HP device has one port-based VLAN (VLAN 1) by default that contains all the device's ports.
Interface VLAN 1 has ip address of 192.168.1.2 255.255.255.0 and the default gateway of 192.168.1.1. why does interface VLAN 1 require an ip address in this this LAN?
Simple answer is: In order to connect to your switch or to do some troubleshooting of the links connected to the switch you require an ip add binded on the switch, therefore to access it or troubleshoot any link connected to it an ip add is used. Detailed answer: For Example lets consider a scenario in which a switch connected to 2 diff sites, A & B. Both A & B are using point to point ip to communicate with each other and are assigned a single VLAN 100 to pass through the switch. Suppose if site B gets down due to any reason and you want to confirm it, you will access your switch and shutdown the port connected to site A because you are about to bind site A's ip address to your vlan interface, finally you will bind the ip address of site A to interface vlan 100 and then ping site B, if the ping response is not successful it means the problem exists in the path & vice versa. This detailed answer is just to clear the concept. Regards, Engr. Emad ul Haq
