I have recently purchased an SG-300-52 Managed Switch. (This is the first managed switch I have used, so I am trying to figure out what I can do with it and how it works.)
I would like to know how to find out the IP address of each computer connected to each port of the switch. Is this possible and if so how can I do this from the browser interface?
We have a pair of Cisco 6513 switches, to which a selection of Wintel/Linux/UNIX servers are attached, but we have some connections that we can't identify and the data centre is a remote lights-out operation operated by a 3rd party in another country. determining which server NIC ports connect through (via patch panels) to which ports on the Cisco switches.In particular, I have a UNIX (HP-UX) server that has 4 dual port NICs (ie. 8 LAN ports), of which only one is assigned an IP address, but I can see that the other ports have connectivity at level 2 (HP-UX has a "linkloop" command that is analogous to an IP "ping" but takes a MAC address, and I get a response from each when I check from another server). This means that I know that there is a physical, electrical, and level 2 connection.The one server port with the active IP address set up shows in the switches address table ("sh mac-address-table") and it gives the port it is attached to. But the remaining 7 ports do not have IP addresses assigned and so are not listed in the table.

View 4 Replies View RelatedI have installed my new E4200 and it works beautifully. I have several wirelss adapters and a few wired connections through powerline adapters. I also have a second VPN router attached to the 4200.I can see the wireless connected devices with the associated IP addresses. If I plug a laptop directly into the Cisco, I can of course see it.However, I can see none of the devices attatched to the powerline devices? I have a securty cam connected via the powerline and want to know the IP address. I checked with cisco technical support via chat and they said it is impossible. I have used 2 previous routers with the same configuration and can see all devices.
View 1 Replies View RelatedI have 2 networks in the house. The main network is called "FIOS", From one of its LAN ports, a cable runs to the power-line adapter #1) and supplies internet via power-line, to my office.Office network called "Leo". A Netgear router with Its WAN port connected to powerline and is getting its internet from Powerline adapter #1 I have devices attached to both networks, and would like them to communicate. (like TV on "FIOS" to communicate with NAS on "Leo")
Main network "Fios" uses Actiontec MI424WR Gen2. Router DHCP enabled: IP schema 192.168.X.X
Secondary network "Leo". uses Netgear power-line Router DHCP enabled: IP schem 10.0.X.X
So I have a TV which is a member of "Fios" , but would like it to access a NAS, which is attached to the Netgear router "Leo"
I've just got a WAG120N router and can't see anyway to see what devices are attached to the router or be able to assign static IP's
View 3 Replies View RelatedIm trying to setup a cable modem which is also a router that has a printer attached to one of its lan ports. From there it connects to another router which connects to other clients from there i have another router with a VPN connection with other clients. I would like to be able to see everyone on the network. How do I setup the routers in particular the router with the vpn which is the last router. Also the vpn router is connected through its WAN port to the router ahead of it at its lan port so it can use its VPN connection.If it makes it easier lets ignore the cable modem as router and ill find the printer another way of connecting but essentially i need the two other routers for two ip addresses. One for the first router with my regular IP and then the other is for VPN IP.

But can 2 programs access each of these ports independently.
View 1 Replies View RelatedMy university provides one Ethernet port per student in dorm rooms. They assign IP addresses based on which port you connect to and forbid multiple computers connected to the one port using a hub or switch.DHCP leases are 24 hours long, but you can switch out 10 different devices with different MAC addresses and keep getting the same IP. How does this work? Do they just figure that if you're using a hub connecting multiple stations to the one port that they don't care if there's a conflict?
View 3 Replies View RelatedI have two WAP4410N devices on my network.When I try to connect with a wireless device (iPad, Smartphone, etc...) it does not connect.However, if I assing that device a static IP, it connects.Here is the setup:
-2 WAP4410Ns that have static IP's assigned to them. They plug into my 3560's
-Three Cisco Catylist 3560, one of which is my Default Gateway.
-Windows 2008 Server R2 (Domain Controller, DHCP, DNS)
On the System Summary screen in the Port Statistics table when you click on one of the Connected links the pop open window does not show the IP address of the connected device when using IPv4. Where can I find this?
If the devices are using static IP addresses and not getting them from the DHCP server they do not show in the Client Table under DHCP Status.
If they are know MAC addreses because they have been assigned to static IPs on the DHCP setup screen they will not show up in the Uknown MAC Addresses pop up window.
We have a Cisco 4400 controller and a mix of 1010 and 1131 access points.
We have been running out of IP's on our DHCP server because the apple devices are not releasing there IP's.
when you have a device that you don't know it's IP what do you do to find it out, I normally just plug directly into the device and use nmap to scan the ranges I think it might be, but that takes quite some time?

View 2 Replies View RelatedI recently installed some wireless IP cameras and when attempting to re-install a camera I went into the DHCP Client table to verify which IP a camera was using to set it up, but I could not...and still cannot see any of my cameras in the table even though I can access three of them directly through the IE web browser. I initially power cycled both the E4200 router and Motorola cable modem, and then later just the wireless router...but I still do not see the devices connected. I currently have 2.0.37 firmware even though I was told by Cisco support that there was a later version available, just before being informed that I do not have support available and could purchase it. I attempted to locate a newer version, but the online upgrade portion of the Cisco Connect software searched the net and then states that I have the latest version available. I also opened a Firefox browser to see if maybe my browser was causing issues, but the same limited table appears without all entries available. I even opened the Cisco Connect software on another laptop with the same limited results. Other than a factory reset, get me E4200 dual band wireless router to show all attached devices through the DHCP Client table as it previously did approximately two weeks ago?

We sold an ESW 540 switch to a 3COM customer that is replacing old equipment. This replacement will be on different faces so we have to interconnect some 3COM switches to the Cisco equipment. We are installing rigth now and this two situations:
Virtual machines can´t get IP addresses via DHCP (using a different MAC address) when connected to the Cisco switch. Physical machines receive IP addresses from DHCP without problem. This situation never happened with 3COM switches.When we interconect the Cisco Switch to the 3COM switches (not using uplink ports) the connection never goes up. Remembering that 3COM switches are old we fixed the speed to 100 Mbps Full Duplex but it didn't work.
I need clarification on cisco WLC 4402 which have two ports .
Can we connect one port on CORP core switch and one port in DMZ zone to bifurcate the guest traffic from WLC itself ?
Is there a way to set static ip addresses to each port on at sf 300-08?
View 1 Replies View RelatedI've got a LAN with private IPs for the computers, and public, static IPs for the VoIP phones. They are a Hosted VoIP provider, and I want to give priority to the public IPs with my ESW-520-48P switch. How do I implement that in this switch?
I have no roles assigned on the ports and no VLANs setup either. I had tried segregating the VLANs first, but eliminated that route. It's all VLAN 1 now in the switch again. For some reason when I implemented VLAN 100 for voice, voice stopped working on the phones, but data was still fine.

View 2 Replies View RelatedI am having a major issue trying to connect my Windows 7 HP Netbook to my Xbox 360 over either Twonky/Serviio or Windows Media Centre. The Xbox just isn't picking up my computer, my homegroup recognises the Xbox and it is 'Allowed' to share media, but when I test my PC connection within the Xbox dashboard, it fails to connect to PC. My network is wireless.The strange thing is I have TwonkyServer Mobile running on my Android phone and that was found by my Xbox immediately with no need to change settings or search for devices. It streams media just fine from my phone. This leaves me thinking that it is an issue with my PC as opposed to my router, I have double checked my router settings (Sagem 2304), UPnP is showing as enabled, I've reset and unchecked/rechecked the UPnP but still not working.
My TwonkyMobileServer is also unable to find my PC server although I have been able to find my MobileServer in Windows Media Player and stream media from my phone.Windows Firewall has been disabled, I've also Uninstalled my antivirus software, Avast and AVG, although AVG doesn't seem to want to disappear that easily and is still lurking in my System Tray telling me i've 'Lost protection'...Norton Internet Security is also lurking around which is odd, I can not recall installing it! It doesn't seem to be a fully installed version and doesn't seem to want to be uninstalled. Could these AV software and supposed Internet Security software be holding me back?This leaves me thinking that my PC is holding back my Network. Is there any thing I haven't thought of? Would it be the Anti-virus leftovers ruining my streaming dreams??

View 2 Replies View RelatedI've been tasked with finding all switch ports that are configured as Trunks. We plan to use LMS 4.2 to push (via Netconfig) new interface level commands to all user (non-trunked) ports. From my experience, this poses a problem because we do not know which ports are configured as trunks -vs- user ports.
Using Netconfig is not going to be easy since there is no way to script this. It would be great if I could run a show command on a switch and then have CWSI peform a change based upon the output.In other words, we need a way to run a job based upon the output of a command.
i am setting up a new Monitoring System (CA Netvoyant). It has some default Cisco monitoring capabilities ( I believe these are soem standard MIBs). I am wondering how can I add more useful Cisco MIBs for the devices I have in my network. There are thousands of MIBs and it looks like it is not easy at all to find the useful ones.For example the MIBs that can give you Emergency and up to warning level information, cpu, memory, interface errors, module failures (in case of Cat 6500), FWSM, BGP, VPN tunnel status notifications. Is there a list of useful MIBs for each device type, like Cat 6500, ASA5540, Cat 3750-E etc depending on IOS Image? setting up the SNMP monitoring system?
