    Follow up: Ok, using real switches (after practicing using Packet Tracer), I now know I can set the hostname, enable the password, then install the switch and connect a port to another configured switch that has the port I am connecting to set up for Trunk Mode and a domain name set for the VTP. That will allow VTP to add the VLAN (or VLANs) to the database.

    However, it does not add any of the ports to the VLAN or VLANs on the replaced switch and without an assigned IP address to manage it, I don't see how it can be remotely accessed.

    So is this possibly how it would be done when a switch fails - instead of sending an unconfigured, brand new, out of the box switch, have the switch sent to the IT dept where they will configure it, then ship it to the remote office?

    Thanks,

    David JR

    I guess I wasn't clear.

    I worked in an 8 story bldg. that had switches on each floor. The local system admins were not allowed access to connect to the routers and switches.

    I was just a help desk low level tech. Wanted to 'move up' but got laid off and the system admins (three of them) weren't going anywhere anyhow.

    So if a switch failed and needed replacing, it would need some configuring. I know they used VLANS because the printers were on one VLAN and the VoIP telephones (I think) were on a different VLAN.

    With VTP running, the new switch would receive the advertisement from the local switch that was a VTP server? But could it receive that advertisement without any configuration?

    And to remotely access the switch, wouldn't someone local have to some minimum configuration so it could be accessed?

    So that is the question / scenario. What exactly would need to be done on a replacement switch besides unpacking it, installing it, connecting the data cables and powering it on?

    Thank you,

    I am working on VTP. That said, suppose you have a remote office where a replacement switch is sent. The switch will 'operate' in the default configuration out of the box. However, to get it to work in the VTP, receiving VTP advertisements, what is the minimum the person at the remote office has to do? Should he assign (by console) the VTY username and password, an IP address and etc so you can remote in and configure it?

    I guess the answer I am looking for would be something like this:

    1. This is the first thing I would have the remote office do.
    2. This is the second thing I would have the remote office do.

    and so on until the switch is configured 'all the way'.

    Thank you,

    I have slowly built up my own lab. Started out with an equipment rack ($500), then one or two routers and one or two switches. Over time, I added more switches and routers, the WIC-2T cards, spare flash's until I now have 10 Cisco 1841 routers, four Cisco 2950 and four Cisco 2960 routers, three Dell Servers (two WS2008 and one WS2012), five laptops, and recently, an HP switch.

    Having all this has been definitely expensive - but I think well worth it. For instance, I learned when you eject a compact flash, it literally 'shoots' across the room and it took me a little while to locate it. So I now know to cup my hand to catch it - something you would never ever learn using any simulator.

    I have also learned Dell laptops do not have a 'break' key which is a very important and needed key sometimes. So you have to connect an external keyboard to the laptop.

    I also have been able to actually erase the flash (on the routers - haven't tried it on a switch . . . . yet) and learn how to connect to a TFTP server and reload the flash.

    I also received a defective WIC-2T card and that was pretty fun troubleshooting it and making sure it was indeed defective. One of the serial ports definitely did not work. Big difference between troubleshooting a defective device in a simulator and a real, actual device. The vendor that sold me the card allowed me to return it and get a replacement.

    And having all that equipment, I can almost pretty much set up any network as diagramed in labs or examples in textbooks.

    Finally, using the lessons provided by ITProTV, I have set up my a router to connect to the Internet and be a time server. That was especially rewarding.

    Yet with all my experience and practice practice practice, still reluctant to go for the ICND1 exam as it is $150.00 and not sure I am really ready ready ready. That is a large sum to waste should I take the exam and . . . . not pass.

    I bought ten Cisco 1841 routers, 4 Cisco 2960 and 4 Cisco 2950 switches. I then learned HP makes switches and added one HP switch. I now have found out Juniper makes switches and thought I'd add one of those since on Ebay I found the Cisco and HP switches for as little as $30 for the Cisco switches and $70 for the HP switch. However, there were no Juniper switches for less than several hundred dollars and some were in the thousands.

    Is there some reason Juniper switches are so much more expensive? How do they compare to the Cisco and HP switches?

    OK, I see my error. The 0. 32, 64, . . . increments are in the fourth octet, So the subnet is 192.168.149.0 and addresses 192.168.149.1 - 30; next subnet is 192.168.149.32 and addresses 192.168.149.33 - 62 . . . and so on. . . .

    I found a subnetting practice site and was doing 'ok' -- until this question:

    What is the last valid host on the subnetwork 192.168.149.0 255.255.255.224?

    224 means increments of 32, correct? So that would be 0, 32, 64, 96,,128, 160 so the last valid address would be 192.168.159.30, correct?

    But the answer given is 192.168.149.30.

    Maybe a typo and they meant 192.168.159.30?

    Otherwise, can you please explain where I am going wrong on this one?

    1. When you have multiple devices connected to a switch and two devices have the same IP address, sometimes an error message will appear on a device if a duplicate IP address is found. Is this message part of the Windows operating system or a message generated by the switch?

    2. When you have a serial connection between two routers and they have the same IP address and subnet mask (such as 11.0.0.1 / 255.255.255.252), it appear neither router has any errors and you can ping that IP address from either router with no problem. Of course, if you try to ping what should be the OTHER IP address (11.0.0.2 / 255.255.255.252), you will get "no reply" and possibly spend several minutes 'troubleshooting the issue' until you realize there is no 11.0.0.2, but instead two 11.0.0.1's. I guess I am asking the serial ports / routers can't detect there is a duplicate IP address and give an error for this configuration mistake?

    Our company uses HP switches. As an employee, I am given an HP ExpertOne account. So I searched for courses on their switches, found (I thought) a course called the HP4-A02 Designing and Deploying Network Solutions. No . . . all it did was take me to Certiport, which referred me back to HP which referred me back to Certiport . . . . Finally spoke to an actual LIVE person at Certiport and they could not find the exam or tell me its cost. Contacted HP and they had Pearson Vue contact me. They referred me to New Horizons in Atlanta and their representative stated they did not have any 'course specific' to the HP ATA certification. They also did not sell or have any study materials or test exams for this certification. Seems like a whole wasted two days in pursuing this.

    So I guess I am asking ITProTv if they know anything about the HP ATA certifications, where to get study materials for it, how much the exams are, how can I be sure I am ready or if just abandon this idea and stick with the Cisco certifications.
