• Cam of the NAC could not add the access switch

  Hi all

  My problem is I can't add the access switch to the cam using mozilla firefox or IE.here attech file cannot add the device. Any idea to solve my problem?

  Hello

  Plese note to add a device (switch) to the CAm, you must go to the leadership of OOB-> appliances-> New.

  First, you must configure the SNMP settings on the switch and the cam so that the cam and the switch can communicate.

  I advise you to make sure that carefully read the configuration for OOB guide and management switch:

• ESXi vmnic teaming and multiple access switch

  Hello

  We intend our ESXi to connect to 2 different access switch to increase redundancy. The two switch connect to core via etherchannel. Currently connect us 2 vmnic to 2 buttons (one on one), assign 2 vmnic vswitch as uplink adapter, set these 2 uplinks as active adapters and load balancing game based on the virtual port id.

  Everything seems fine until I found KB 1001938 said "ESX/ESXi host only supports grouping NETWORK adapters on a single physical switch or stacked switches. Is there a problem with our Installer? If so, how should we configure redundancy of the network (different access switch?)?

  There is no problem and your solution is fully supported. The article describes the aggregation of standard links 803.2ad (called "IP Hash" on ESXi) who has the above requirements with a single or bunk physical switches.

  When you use the method of identification of the Port without problem, you can connect multiple physical switches in the host, make sure that all the VLANS are available on all links of the switch.

• Synchronization with Outlook Web Access

  I recently installed Thunderbird to access the professional email using Outlook Web Access. When I move a message in Thunderbird to a folder, I see that he is still in the Inbox in Outlook. There must be a setting of synchronization that I'm missing. Help is very appreciated.

  Lets see. OWA is not IMAP. You can access the exchange e-mail via OWA. Either using davmail or the add-on exequilla.

  The implementation of IMAP in Exchange is odd. This is mainly because that Microsoft never intended anyone to use effectively, but supported marketing needed to be able to tell. So you have Mail.imap.expunge_after_delete set to true and restart Thunderbird.

  Many parameters that have no user interface are read at the start of the program.

• Cannot access switch GS108E on Windows 10

  After the upgrade to windows 10 I can't access my GS108E switch. Get "an error occurred communicating with the server. "Error message: HTTP request error". No idea what is the problem?

  I have reset the default switch & it works now in WIN10. Wish I could label each port so I don't know what connected to it. It's a disappointment, not knowing that I have connected to all 8 ports. I should be able to label each port with a name. This can be done? Thanks for your help. Close the case.

• can the WRT54GL router be configured to operate as a point of access/switch?

  The router connected to the internet is a WRP400, and I've got a WRT54GL connected via PLN to improve the signal. I would like to have the WRT54GL work like a switch and point of access, is this possible? The problem is that, in order to have my TV box work, I need the WRP400 to assign IP addresses.

  Hi Matt, I wasn't looking to recreate because I think I know the problem, that goes back to my initial suspicion.

  You have many things going on, basically, I think you're too smart for your own good.

  • If you have car insurance, you don't need to manually tag the VLAN, so your config from port to manually set 100t can be breaking stuff
  • You have the policy of lldp attributed to the port assigned by the voice of the auto

  To make this as painless as possible, I would like to switch (back out config is boring and takes too long in my opinion).

  Use this document for the LLDP-MED

  https://supportforums.Cisco.com/docs/doc-27005

  It must be remembered that automatic speech depends on the protocols of discovery as the cdp and lldp. These auto policies don't produce any results or undesirable if already manually set you the parameter. The switch performs a basic QoS for the CoS and DSCP to tag packets, so that is why everything is basically done twice - or more based on this config.

• Cannot create the IPv4 Interface on switch SG300-20 entries

  It is a brand new switch, mode of L3, and I am connected to port 5. By default, all ports are VLAN1 (management) defined as the PVID and are defined in trunk mode. I can connect without problems, and nothing else is connected to the switch.

  I did a master reset (via the web interface and button reset for 20 seconds) several times, and every time I try to assign an IP address to a VIRTUAL LAN on the page located at IP Configuration > GPI and Interfaces > Interface IPv4, I lose connectivity to the switch and it should be reset.

  I make no changes to the VLAN1 (management) or the port I am logged in, but the problem persists. My switch is bad? Thanks in advance.

  Hello Terry,

  It is done, your switch has several types of IP addresses,

  -static IP address (you set this)

  -dhcp (a server or router that sets)

  -default (if neither of the other is defined) 192.168.1.254.

  If the sg300 or 500 device has the default IP address and add another IP interface (on a virtual LAN or on a port), it will determine that static or dhcp is the management interface and the address 'by default' won't work any more.

  The workaround for this is:

  When you configure layer 3 routing on a sg300 or switch 500, once the switch is in mode l3, you must:

  1 - give each VLAN interface a static IP from vlan1.  This can be the same as the default 192.168.1.254, but I recommend to choose another address where you decide to add another switch in the future.

  2 - before you set an IP address on the new VLAN, assign a port of access to the new vlan (so you can move your desktop to this vlan) management if necessary.  management of VLAN--> belonging to a vlan port.  Once you assign the ip address and your management interface goes far, move your pc to port on the new virtual local network, give it a static and reconnect to the new IP address.

  3. use the cable from the console and CLI to configure the interface vlan, as the console port does not go down, or lose connectivity when configuring a VLAN.

  Hope this helps,

  Dan

• Need help setting up switch SG300-10

  Hello

  I bought a SG300-10 switch and configuration.

  I have a problem to set up it causes that I'm not really used to networking.

  what I set up at the moment is the VLAN.

  VLAN 2 - step my router it for internet access

  Vlan10 - is for my server and pc in my office

  VLAN 40 - is for the wifi of comments.

  I will use the mode switch layer 3 and I want to configure a DHCP server on the vlan 40 but I'm not very well how to do.  I activated the DHCP and created a pool of ip but how I assign on the vlan 40? and how to set up everything to go on the internet? If I followed the basic logic, I will put all my members of port of vlan 2, is that correct?

  IM new in the field of networking

  Thank you

  Hi Justin,

  Here is some basic information for the switch. With VLAN, it is tag VLAN and remove the brand VLAN. A package of UNTAG means in the package header, there is no VLAN ID. The switch will provide separate from the client connection based on the transfer of bridge table. Usually UNTAG VLAN is used for the client connection. A beacon packet contains the VLAN ID in the header. In general, tag packets is used between other network device. An access port is member of 1 VLAN that is not marked. A trunk (on small business product) port is a port that has 1 UNTAG VLAN (VLAN native) and has the ability to tag the VLAN extra.

  Some examples of configuration CLI for tag and remove the brand VLAN. Keep in mind, VLAN 1 is the default VLAN, therefore, unless you make sure, VLAN 1 will default.

  To create a VLAN 2 on your switch

  Configure the terminal

  database of VLAN

  VLAN 2,3,4

  This will create the VLANs 2, 3 and 4

  To configure an IP address to a VLAN

  Configure the terminal

  interface vlan 1

  IP 192.168.1.254 255.255.255.0

  interface vlan 2

  192.168.2.254 255.255.255.0

  interface vlan 3

  192.168.3.254 IP address 255.255.255.0

  interface vlan 4

  IP 192.168.4.254 255.255.255.0

  Keep in mind, VLAN 1 must have a static IP address before you assign any other VLAN an IP address, or the switch will "lock".

  To assign an access as a member of the VLAN 1 port

  Configure the terminal

  Article IG1 interface

  switchport mode access

  To assign an access as a member of VLAN 2 port

  Configure the terminal

  interface hi2

  switchport mode access

  switchport access vlan 2

  If you check the GUI you'll notice port 1 is "1u" and port 2 is "2u".

  To create a trunk and assign some VLAN-

  Configure the terminal

  interface IG3

  switchport mode trunk

  switchport trunk allowed vlan add 2

  In the GUI, you will notice 3 port will be "1u, 2 t".

  To configure a port to have a VLAN different other that 1 as it removes the brand on a chest.

  Configure the terminal

  interface IG4

  switchport mode trunk

  switchport vlan trunk native 2

  switchport trunk allowed vlan add 3.4

  On the GUI, it will show '2u, 3 t, 4 t'

  Now that we have fundamental port assignment of the road, you can work on DHCP and IP address management.

  When the switch is in mode layer 3, if there is an IP address assigned to a VLAN, it is a switch virtual interface (SVI). The IP address of the service VLAN as default gateway which connects to this VLAN. The switch can associate the pool DHCP IP interface created on the switch-based layer 3.

  Firstly, we must establish your first jump of the switch - the default gateway of the switch statement. If you have a router connected to the SG300 you must assign the SG300 default gateway, which is the IP address of the router.

  Configure the terminal

  Default IP gateway 192.168.1.1

  Then you can concentrate on your DHCP scope. To configure a server DHCP table here is an example-

  network IP dhcp pool PRODUCTION
  

  address 192.168.2.1 low high 192.168.2.253 255.255.255.0

  Infinite rental

  default router 192.168.2.254
  

  dns-Server 8.8.8.8
  

  This basic table DHCP said many things.

  The name of the table is the PRODUCTION, this can be anything you want.

  low address is the first IP address that is assignable in the pool while high address is the last

  infinite lease means that had not expired DHCP lease

  Router by default, it is the most important. It is the default gateway, that the switch will be assigned to the customer. This is very important if you want router between VLAN or upstream of the internet

  DNS server, this allows to resolve the name instead of having to use IP only.

  Now, if you connect to a computer that is enable DHCP where VLAN 2 is not marked, you should receive an IP address that is assigned by the switch on this computer. Notice that the pool is a number of address IP 2 VLAN. The definition of IP pool, this is how it will bind to one VLAN, by matching the subnet.

  Now, once you have all the basic configuration complete, as Marty says, depending on the capacity of your router, it will need to need to support VLAN tagging, interface sub dot1q OR, as Marty has said, it would need static route to allow to your additional subnet route on the internet.

  Hope this will help you get on your way.

• SG300 - how to block access to administration

  Hello and thanks in advance for you help.

  I have a SG300 working mode switch layer 3.

  I created 3 VLAN and intervlan communication works very well. I want to know how to block access to enable management of VLANS.

  The vlan is allowed access to the switch, but not the other vlans.

  What is the best way to implement this? with ACL or the method of access management, by creating an access profile?

  Thanks againg!

  Hi Angel

  List of work on packages that through the access switch.

  Try the next method to restrict access to the management interface.

  

  Take a look at the section of MISTLETOE on the security > Mgmt Access Method > profile of rules and see what methods or restrictions better meet your needs.

  Best regards, Dave

• Mask problem Switch SG300-28 30

  I seem to have a problem using a 30 mask my SG300-28 switch L3 mode.  I want to isolate my router in one VLAN separated.  I had one VLAN created with a 24 mask and it seems to work.  I tried to change the mask on the switch and the router at 30.  There is no DHCP on this VLAN.  I cannot ping either side of the switch or router.  In the configuration screen to assign the IP address to the VLAN there you can use a mask from 8 to 30.  When I change the 30 to a 24, it works very well.

  I use a configuration access port for VLAN router.

  Using a VLAN and an access port is perfectly fine.  There should be nothing wrong with that.

  I don't know if this switch supports, but you might be able to do a "no switchport" and then put the IP address on the interface.

• C3750 interVLAN routing - no internet access for customer switches

  I have a stupid question with my itinerary (intervlan).

  I have a test configuration to a stack of C3750 as core and a few 2960's like access switches.

  http://users.fraeco.be/setup.png - switch at the bottom is the new network (VLANNED). The switches on the left is the current network of production (10.1.1.0/24)

  The C3750 to the router is a 30 network.

  There will be 6 VLAN but at the moment I have one configured. VLAN50 - 10.5.1.0/24

  The C3750 I can ping my network current production, internet, other VLANs in the testsetup... Everything.

  Of the C2960 I can ping other VLAN, join the entry door, reach the router, reached the currenct production network. But I can't reach internet. I have configured 'ip default-gateway 10.5.1.254' on the C2960. C3750 relevant config is down below.

  How can I reach other networks connected to the router and the internet not switches to access? I'm trying just to ping 8.8.8.8.

  Hi, Maxim,.

  I have no idea about your configuration exactly but for the account information that u as far as I can tell... Configure all the respective host to its ip address vlan respective gateway.

  There should be a static route pointing to the router on the switch of the MLS.

  And also, make sure that it should be static (or entered dynamic in case you use PGI) of all subnets of VLANs pointing to the ip directly connected inverter MLS.

  It will certainly work.

  Thank you

• 4506E Core and 2960S access IP Camera System switches

  Hi all

  I implement my first Cisco network and needed a little guidance. Here's the scenario and I wish that it works:

  • 2960S access switches will have cameras IP PoE and POS stations connected to them with the core fiber uplinks.
  • 4506E central office switch will have all the switches connected to the fiber SFP uplink ports access. All fiber optic cables are single mode with LC connectors.
  • All the cameras IP PoE and the other the camera server NETWORK card will be the 172.16.0.0/16 network and in case of default Vlan 1.
  • All computers of end users and a NETWORK card in the camera server will be on the 192.168.1.0/16 network and Vlan 2. 2 VLAN is needed as the main switch.
  • All stations of POS and stand-alone server POS will be on 192.168.20.0/16 and Vlan 3 switch network access and the base.
  • It will be a completely closed network, no internet access.
  • Computers end users will access video server with raids unicast.
  • All switches interconnect fiber SFP transceivers of 1 GB.
  • VLANs are not to communicate with eachother, just need to Vlan 1 and 3, be passed on to the switch base. It will be setting ports in the trunk switchport mode correct?
  • I gave all the devices static IP networks, with the exception of IP cameras that will get the IP Address of the DHCP server.
  • When I plug in a device of watt PoE 15.4, is the port set to auto detects by default so it lights camera or manually activate PoE on the port?

  -I have to run DHCP on central switch, only on the default Vlan 1 172.16.0.0/16 network so my IP cameras can obtain an IP address.

  IP dhcp pool cameras

  network 172.16.0.0 255.255.0.0

  default router 172.16.0.1

  -On the PoE IP camera and POS station ports I think following configuration:

  switchport mode access

  spanning tree portfast

  I would like to know what you think. I have a few weeks before they must go to the production. Any help and advice will be greatly appreciated!

  I will be checking periodically the thread and display updates.

  Yes I see!

  So with each carpet use "port 1' for each channel.

  for example

  If we have a stack, there that a single etherchannel, should therefore be port-channel 1 (the first 6). This could bind to the 4500 to Portchannel 1

  When we have the second battery, it will also be an etherchannel, which is the port-channel 1 (the first 6).

  This could bind to the 4500 on Portchannel 2

  and so on... The port-channel number is locally meaningful only so you don't meet for loops if its configured as suggested, etc...

  This way you can keep it simple and you will have ease of management in this way.

  No, there is no point linking medical examinations to configure

  Hope it makes sense.
