8 port or 16 port switch

I am using 8 port and 16 port switches in my organization. Is there any way to block the ports since there is no IOS that comes in these switches?

The SD216 is an unmanaged switch, so there's no way to block the ports from
software.
What you could possibly do:
block the ports physically: stuff something in the unused ports, like vax or something. This will void your warranty, though.
if you have a managed switch between this SD216 and the rest of the network, assign static MAC addresses on that switch and disable dynamic learning.
Cheers,
Tamas

  • Can I create a port channel to two switches that are not stacked?

    Two switches, not stacked, but connected together via 802.1q trunk.
    Server with four NICs, capable of trunking and LACP.
    Can the switches be setup to have an etherchannel between the two switches and the server?

    Hi,
    In short NO
    You would need to connect your server to only ONE switch if you want all 4 nics in the same TEAM.
    You could use 2 TEAMS and put 2 nics in each forming a 2 port etherchannel to each switch

  • Converting Eth port to FC port in a cisco 6001 switch

    Hi,
    Back to forum after a long time. I have one issue to discuss regarding cisco 6001 switch. We purchased a new 6001 switch. Want to convert some of the Ethernet ports out of total 48 to FC to join the switch into a existing fabric.
    cisco Nexus 6001 Chassis ("Norcal 64 Supervisor")  - This is what H/W version look like from show version command.
    In the past, we have quite a few Cisco 5548UP switch and the way convert the Ethernet port into FC port is, by going to correct slot/module and then
    (config)# slot 1
    (config-slot)# port 41-48 type fc
    Then "reload" willl complete the conversion. But in the new 6001 switch, it throws the following error when above command is typed. We have full license for the switch including  FC_FEATURES_PKG
    "ERROR: Module type doesn't support this CLI"
    We are running firmware : 6.0(2)N2(2)
    Any help in this regard will be helpful.
    Thanks.

  • What can be the max difference in cable lengths that we can have between the ISLs in a port-channel between MDS switches?

    Hello All
    What can be the max difference in cable lengths that we can have between the ISLs in a port-channel between MDS switches? Do we have any documentation?
    Thanks
    Chetan

     competitive solution instead recommends a distance variance of 30 meters or less among ISLs within a trunk. If the distance variance is greater than 30 meters, undesired and degraded performance will occur. For example, if a trunk has a distance of 100 kilometers, the competitive trunking solution allows a cable length variance of only 0.03 percent!

  • 2-Port Dual View KVM Switch

    I'm about to purchase a 2012 (late fall) Mac Mini.  I currently use a G5 Tower w/Tiger, with two monitors VGA monitors.  As technology changes faster than I can keep up, is there a chance that "2-Port Dual View KVM Switch" means I could connect two monitors at the same time?  I want to be able to switch between the G5 and the Mac Mini.
    Part of the discription reads: This new KVM Switch lets you control two dual-head, VGA-enabled USB computers from one USB console that includes two VGA monitors.
    Please advise.
    Patt

    Thanks Eric,
    I know that Kvm is used to swap between two computers, what I don't know is if there a way to swap dual monitors.  If I continue to use my G5, as this has all the software I use, and soon the internet will become less and less usualble on the G5, will the KVM work swaping back and forth if I use two monitor on my G5 and one monitor on my Mac Mini?  Of course, my goal is to continue using both my VGA monitors for both Macs.
    I'm understanding that since the 2012 Mac Mini only has room for one VGA monitor which is connected to the thunderbold port via an adapter which comes with the Mac Mini  (true or false)?
    I'm understanding that I could connect the Mac Mini to two VGA monitors if I purchase an adapter that would connect to the HDMI port and using the DVI port/adapter VGA - I can connect two monitors. 
    But will the KVM have the means for swapping the mouse, keyboard and two monitors back and forth? This is my big hurtle.
    This is what I saw on the discription that was different from other KVM discriptions.
    "This new KVM Switch lets you control two dual-head, VGA-enabled USB computers from one USB console that includes two VGA monitors." 
    You were very kind to help, I hope my clarification helps.

  • Port Groups on Multiple switches

    Is it possible to create a port group that contains ports from multiple physical switches. We are using Catalyst 3500 series switches that are connected to a Catalyst 6509 running layer 3.

    The Etherchannel do not HAVE to be on the same switch.
    You may configure an etherchannel between 3 physical switches :

  • Cisco 5 port and 8 port gigabit unmanaged switches

    I am looking for 5 port and 8 port gigabit unmanaged switches in Cisco. Please provide the BoM for the same. As per my understanding the following switches can suffice the requirement (SG100D-05 and SG100D-080) however I am not sure about the DC power, whether they can be used in normal AC environments.
     

    The SG100D-05 and SG100D-08 are too small and their power requirements are too low to justify building an AC power supply into them like the larger SGx00 switches have, so they are wired to accept DC power and use an external power adapter (included) for connection to an AC environment.
    There are really no optional components to these devices, so the BOM would be as follows:
    5-port SG100D swich: SG100D-05
    8-port SG100D swich: SG100D-08

  • Port aggregation on different switches?

    Hello all :)
    I got a server PC with two fast ethernet NICs (NICS do support port aggregation)
    I know you can connect two 100 Mbps ports of server to two fast ethernet ports of a switch, this way you get one 200 Mbps link. If one of the ports or one of the links fail, other link keeps working.
    this is a vey nice redundancy.
    My question is;
    is it possible to bundle two fast ethernet ports of server to two different switches? (first ethernet port of PC to switch 1 and second ethernet port of PC to switch 2. switch 1 and switch 2 are connected each other with an uplink)
    if possible, what is the CLI command for that?
    thank you very much for helping.

    Hello,
    AFAIK, and unless something has changed very recently, the only way to link two (or more) switches together in a single Etherchannel is in a stack configuration.
    Nortel appears to have a feature called Split MultiLink Trunking, which does multichassis trunking, you might want to have a look at the document below:

  • Nexus M1 Series 32 port 10G Module Local Switching Support ?

    Hi,
    Ive got d 32 port M1 series linecard asic architecture slide below.
    There seems to be a local fabric asic on this M1 series card. Anyone knows whether if this module supports local switching and what is the capacity of local switching ?
    We are all aware that this module sits 80G on the chassis fabric modules.
    Thanks.

    4:1 mux is downstream from replication ASIC which has total 10Gb toward each front panel port-group. So correct you can never put more than 10Gbit/s in/out combined across the ports in one port-group.
    As an example say ports 1,3,5,7 each receive 10Gbit/s unicast for ports 9,11,13,15 (1->9, 3->11, ..) The port-group only has 10Gbit/s upwards so incoming excess is dropped at mux and depending on packet ordering you'd get around 2.5Gbit/s out on each port 9,11,13,15.
    This is why the module has an 80Gb fabric connection, as there is only 80Gb from replication down to front-panel ports the fabric ASIC will never see more than 80Gbit/s so doesn't need any more channels.
    Cheers,
    /Phil

  • Connecting Rv180w and D-Link 5-Port 10/100/1000 Switch DGS-1005G

    This simple exercise has become a pain. I have a D-Link 5-Port 10/100/1000 Switch DGS-1005G connected to an old (10 years old) linksys 4 port router and it works fine. When I try to connect the switch to my new RV180W it appears dead...no connectivity lights at all. I cannot see an uplink port on the RV180w.....I have tried crossover cable still no joy. Am I missing something?

    Hi Tom,
    Yes i am pretty sure, i have called 3S vision and confirmed it, also i conducted 3 test in 3 different switches last week and the camera worked just like that " Plug & Play ".
    I have tested out 3 switches and they are :
    Cisco Switch 16 Port 10/100
    Netgear 8 port 10/100
    Cisco Switch 8 Port 10/100
    I was able to view the camera and modify the settings, upgrade the firmware, etc. all worked, except this model !!!!
    I am losing hope on this and we are considering buying another switch which would be a waste of money.
    Is there is any possible way to enforce the port to read it?
    Also i have noticed one thing, whenver i plug the Camera to SG300-28P switch, the camera has a small led in the motherboard which keeps blinking red when its connected. It is like its trying to boot but not able too.
    I have until the end of the week, if this issue is not sorted out with this switch model, i will have to buy another one

  • CER Use port description as port location

    Hello all,
    I am trying to confirm if this "feature" is as useless as I have found it to be. From my testing and what little documentation I can find when checking the "Use port description as port location" check box on the LAN switch details screen this will ONLY show you this information when looking at the switch port details screen. It DOES NOT actually use the switch port description as location information for the 911 call notifications. 
    My hope was that by checking this check box the switch port description would override the ALI location information configured within the ERL assigned to the switch port that the phone is connected to. This would allow the creation of one ERL/ALI per building say and the device specific room level information would simply come from the switch port description. With out this option a ERL/ALI has to be created for every room in the building. 
    Thank you all.

    There's absolutely no problem in choosing 8888 as admin port while installing IWS in solaris Environment. Just make sure u follow these steps while installation:
    (1)You should choose a random number for the administration server to make it harder for anyone to breach your server.
    (2) Make sure the port you choose isn't in use. Look at the file /etc/services on the server machine to make sure you don't assign a port number that is reserved for another service. If you choose a port that is being used by another service, the installation program prompts you for another port.
    (3)Note :If you choose a server port number lower than 1024, you must be logged in as root to start the server. After the server is bound to the port, the server changes from the root user account to the user account you specify. If you choose a port number greater than 1024, you don't have to be the root user to start the server.

  • Root port vs Designated port?

    To my understanding, the designated port becomes the forwarding port, which means that its forwards frames. Root port has the lowest bridge ID and it also forwards frames...does this mean that the root port is the designated port? what is the difference? When is there a root port and a designated port on the same switch?
    Thanks in advance for your help.

    Hello,
    it might be easiest to understand the difference when you look at it from the perspective of the root switch: the designated port is the port leading away from the root bridge (that is why all forwarding ports on the root are designated ports), while the root port is the forwarding port on the non-root switch pointing towards the root.
    Does that make sense ? Here is an extended explanation from KnowledgeNet:
    Q:What is the difference between the root port and the designated port on a non-root bridge router. I know how the designated port is determined, but just what does it do?
    A:To understand the differences, you must understand the concepts of the root bridge and non-root bridges. Remember that STP creates a logical layer 2 tree of your bridged network. At the bottom of the tree is the root bridge and every other bridge has only one (active) path to the root bridge. To create this tree, STP places ports in one of two states: blocking or forwarding. Determining which port should be blocking and which port should be forwarding can be done automatically by the STP algorithm or you can give it a little help my modifying some attributes such as bridge priority, port cost, port priority, etc. Assuming the root bridge has been selected, each port on the root bridge becomes a designated port and therefore a forwarding port. All other bridges are now considered non-root bridges. To create the tree throughout the topology, STP will go through two different types of elections: root port elections and designated port elections. Every non-root bridge will select its best path to the root bridge. The best path port is called the root port. To stop loops, the third election (called the designated port election) comes into play. Here, each segment in the bridged network elects one designated port and places it in forwarding mode. This designated port is the branch leading away from the root. The idea is, if you only have one port handling traffic on a segment, no loops can be formed.

  • 24 port or 48 Port 10/100/1000 with 4 POE

    Hi I need to offer a solution to a cusotmer with 24 or 48 port 10/100/1000 switches with minimum 4 POE Ports
    DOes Cisco have this solution

    4 ports only for PoE? I think buying a 24-port PoE is a very expensive choice. May I recommend you buy a 4-port mid-span PoE switch instead?
    If you Google "mid-span" poe, you'll find a number of manufacturers.
    Another thing I would like to know is what are you trying to connect? Mid-Span PoE ports comes in a variety of "flavours", some will give you STANDARD 15.4W (or less) power but there are some which can give you 20.0W or 30.0W of power per port.
    Now, if you are still determined to get a PoE switch, I would like to determine from you, for a 48-port PoE switch, if you want ALL 48-ports capable of delivering PoE? If you say yes, then the only choice you've got is the WS-C3560-48PD-SF or WS-C3750E-48PD-SF.
    WS-C2975 (48 10/100/1000 PoE up to 24), WS-C2960G, WS-C3560G, WS-C3750 (24 OR 48 10/100/1000 PoE up to 24) are likely candidates.
    Hope this helps.
