    Setting up medium size hardwire and wireless network, need a few bits of advice... calling you network gurus

    your router should not be the "core" to your network. Routers are usually edge devices. My advice: Get a central switch 24 port, a good one (Cisco, 3Com, HP) as this will be the lynch pin to your network. Connect everything to that as your central point. resist the temptation to...

    Cisco Gurus, I have a question.

    list price is ~$25K, it is slated to go bye-bye shortly. in essence what is does is assign users to a specific VLAN and then maintains that assignment regardless of where on the network that user plugs. This rather than assigning a specific port to a specific VLAN. It is useful if you have...

    Very weird IP problem

    Comcast may be proxying your IP address. You get 1 IP address from the ISP which is, in reality, an address on ISP's private network, which is then NAT'd and shot out onto the Web. Too many users and not enough public IP addresses to go around.

    VPN Router

    it depends.... if you are doing a router to router VPN: yes if the VPN router is 100% IPSec complaint and you have a Mac VPN client: yes (http://www.apple.com/macosx/features/windows/) If none of the above: good luck

    house to house wireless networking. What is needed

    wireless might work, but for it to be effective you need a clear line of sight. if there is a stand of trees in the way and you can not clearly see the house in the summer, then wireless will more than likely not work. At 500 yards (and ever 500 feet) you are beyond the range of standard...

    VPN and CPE

    a few reasons: because the owner of a private network is responsible for the material on it and if you merrily download or distribute copyrighted material, the network owner is liable. If the BSA shows up and your company owned machine has 27 copyright protected (but with no licenses) items...

    I need a 24 port switch

    it sounds like you want to set up what is called a "private VLAN"...where every port (save one) is completely isolated from the others and all traffic from one port can only be sent out to and received from the common promiscous port. This is quite common when you set up a multiple dwelling...

    [Stupid Question] Why is alot of internet access "asychronous"

    one other thing: think about the "average" user...most of their upstream requests are small and are for more bandwidth intensive content coming back so it makes sense to limit the uploadspeed to benefit the download speeds. it just more efficient use of bandwidth.

    Small Business Wired Router...what to get?

    yes, it comes in a 10, 50 and unlimited user flavors...as to the thru put, for most applications you will probably run out of WAN bandwidth before you'll overrun a PIX 501 (up to 60mbps cleartext thruput and 3mbps for 3DES encrypted traffic thruput)

    What is a VLAN and how does it work?

    tagging and untagging is used to determine the priority of traffic. Hypothetical: 2 (VLAN #1 and VLAN #2) network streams arrive at 1 port simultaneously, which one goes 1st? with tagging, the IT folks can say that VLAN #2 traffic is more latency sensitive and should go 1st to avoid...

    What is a VLAN and how does it work?

    a VLAN is a virtual LAN. It allows multiple users to be grouped together in a common IP subnet without worrying about physical location. For example: we have Bob, Sally, Manny and CHuck on the 1st floor; Connie, Mel, Sam and Mike on the 3rd. All of them are connected to different...

    Can resellers sell old stock Cisco switches as new??

    Can resellers sell old stock Cisco switches as new??

    the part number ends in RF generally not the serial number. but in this case, I might be concerned, based on the serial number it appears that this was built in mid to late 2003... if it is that old there are a couple of reasons: 1) the reseller bought it and it got hung in their inventory...

    What Cisco Router to buy

    Layer 3 switch definitely. while a router is capable, you have indicated a "large amount of data flowing" and depending upon the amount of traffic, a router may be overrun by the bandwidth requirement. BTW, the 3550's have been disco'd and the recommended replacements are the 3560 family.

    wireless router question?

    it's got 4 LAN ports, so as long as you use those to connect devices to the LAN and not use the WAN port as an uplink you will be fine.

    Layer3 Switch recommendation

    Not exactly easy to understand but if I am interpreting this correctly, the Summit 200-24 is, out the box, an L3 "lite" switch. It has all the doo dads of a good solid L2 switch with some of the more entry level L3 features. Its "claim to fame" appears to be the ability to upgrade the software...

    Layer3 Switch recommendation

    If you are pushing a lot of L3 traffic, do yourself a favor and don't use a router. While the pricing can be attractive, you will very quickly find that the performance delta between a router on a stick (aka poorman's layer 3 LAN solution) and a dedicated L3 switch is significant. Most decent...

    Where is the bottleneck in this networking situation?

    if the primary purpose of the wireless connection is to allow internet access, mainly browsing, then both the wireless and DSL connection will compete to be your slowest links. wireless has the greatest set of variables (distance from AP, overall signal strength, power settings on the laptop etc).

    Same or different SSID for 2 AP on same network?

    the wireless client should seamlessly transition from one AP to the next as you roam or conditions change. the only reason that you would have multiple SSIDs on the same wireless network is if you want to "force" certain clients to specific AP's. This is common in areas where employees and...

    Opinions on 802.11a?

    11a, while pricey, is an excellent solution in a highly competitive wireless environment. As there is little other common equipment that runs in that freq range, interference is an uncommon occurence. In addition, due to this lack of interference and freq competition, it is a very popular site...
