• 6248 FI Cisco's UCS with Cisco catalyst 2960 connectivity

  In our environment, UCS, connects the two fabric as a Cisco Nexus 9 k switch upstream with vPC and it works well. But we need to isolate some virtual servers on the blades of the UCS on an entirely separate DMZ switch which is Cisco catalyst 2960.

  (1) so can we connect cables separate physical twinax of FI uplink ports to catalyst 2960 and connectivity to the servers in the DMZ keeping YEW to nexus connectivity as it is?

  (2) in this case, as there are 2 switches to nexus core 1 and 2 so we will require 2 cisco catalyst 2960 for disjoint such a network? or otherwise we can connect A FI and FI B to one on his 2 numbers 2960 switch. Gig SFP ports + 10?

  (3) also suggest things must be taken in charge, the best guides practice or an illustration in this context.

  The assignment is static and cannot be changed.

  location 1 - uplink 1

  slot 2 - uplink 2...

  If a property has no blade, the corresponding uplink is not used and that can not be changed!

  This dedication of uplinks of IOM is of course a lot of resources: cables, ports on FI, allowed port,...

  Have you run wireshark on the server because the request to switch? If so you make sure that there is a response from the server? For Windows network POLICY Server (I've never tried Centos), you must ensure that the request is related to a policy which then authenticates, or denies access. Usually, it is a matter of such attributes and the seller.

  Regarding the configuration, it seems a bit out of the AAA. Try to remove the:

  line "aaa dot1x group service radius authentication" and this by using instead:

  "aaa dot1x default radius authentication group". After the dot1x word you are supposed to provide a list of the authentication or the default Word if you do not want to use a list.

• Web authentication Catalyst 2960

  Hello

  I am trying to configure Web authentication relief on a catalyst 2960 switch. The goal is to authenticate customers via web authentication that are consistent (the part of 802. 1 x works fine) not 802. 1 x and allow them access to the network. The problem is that the web authentication seems to fail.

  The equipment about my question: switch catalyst 2960 (version: 122 - 37.SE) and a FreeRadius.

  Here's what happens:

  The authentication window will appear in my browser and the access request is sent to the RADIUS.

  The term RADIUS replies with an Access-Accept. Debugging running on the switch show that all this information is coming properly authentication and switch outputs debug a 'status = PASS' and permission to debug outputs a 'status = PASS_ADD'. Despite this the browser on the client generates a message "authentication failure".

  I have read the manual and the Cisco attribute value pairs are mentioned: ' priv-lvl = 15' and «proxyacl...»» ». They are required to make it work? Given that I'm not setting up any authentication switch connection via RADIUS.

  Any suggestions?

  Thanks in advance

  Yes, they are mandatory.

  If priv-lvl = 15 is not returned to the switch, the user will see? Authentication failed? and the access list will not apply. If the source in the statements of proxyacl field is not? everything? or there are other errors of syntax, the user will see? Successful authentication? but the access list will not apply and the user will be denied access to the network.

  Not sure about the configuration of specific FreeRADIUS, but you need to set up the? [026\009\001] Cisco av pair VSA. It should look like:

  Priv-lvl = 15

  proxyacl #10 = ip permit a whole

• Aironet 1252 with catalyst 2960-8TC-L & 1841 router compatibility

  Hello

  First of all they are togther a good combination?

  I'll buy new ap 1252 and switch catalyst 2960-8TC-L my question can I connect the access point to 1 x 10/100/1000Base-T/SFP (mini-GBIC) (uplink) port?

  because to work on ap with capacity 300 Mbps, it needs port 1000, I will use to power ap powerinjector.

  It will be 15 sereve pc as a working group and 60 customers on wlan.

  Concerning

  Saher

  Depending on the type of traffic and bandwidth customer requirements demand, you might need a couple more of ap which means you may have to settle for a switch of 24 ports. Cisco recommends 15-25 users by so, but still, you can have more if it's just e-mail and web browsing.

• Dot1x multidomain on Catalyst 2960

  Hello

  I improved my 2960 with the latest basic version of LAN 12.2 (46) which includes the authentication of domain Multi (MDA) and I tried to configure what is described here:

  http://www.Cisco.com/en/us/Tech/tk389/tk814/technologies_configuration_example09186a00808abf2d.shtml

  I have the following exceptions in my configuration:

  (1) SE - cat 2960 with the latest version of IOS 12.2 (46) that supports the MDA;

  (2) using the Win2K IAS as a server radius. and

  (3) third party (Avaya) with active begging dot1x IP phone. I have a PC with ability to dot1x connected to the second port of the IP phone.

  That's what I set up on the phone IP port:

  interface FastEthernet0/9

  switchport access vlan 221

  switchport mode access

  switchport voice vlan 222

  dot1x EAP authenticator

  self control-port dot1x

  multi-domain host-mode dot1x

  I also configured the server Radius IAS Win2K to send RADIUS 'cisco-av-pair attribute' tell the authenticator (Cisco Catalyst 2960) that a supplicant (IP phone) is authorized on the voice VLAN as described in config-notes above link.

  When the supplicant IP phone starts to authenticate, he succeeds, but that the port does not allow the field of VOICE, even though the 2960 receives the attribute "cisco-av-pair" of the Radius Server RADIUS. I confirmed the reception of this attribute of debugging on the switch.

  Greetings.

  Please confirm you learn your esxi mgmt addresses (VMK0 will inherit mac vnic UCSM) on FI: #connect nxos

  #See table of mac addresses

  Do the same on your 2960 switches.  You see the mac addresses on the ports of 2960 connected for the UCSM uplinks?

  Your uplinks UCSM go the 2960 into a port channel?

  Can someone tell me a method of turning off the function of the Mode button on a catalyst 2960 to stop this reboot of the switch after being detained for 10 seconds? Even with a config full on the switch, the function "reset" always seems to bypass the config and clear/reload the switch.

  Is it possible to disable this feature in the software?

• The Catalyst 2960 G switch configuration

  Is it possible to configure a Catalyst 2960 G Switch to act as / be an unmanaged (no router) switch?  If so, please provide detailed and simple instructions.

  Hi @lcbalogh1,

  I think that these switches are not routing compatible, but one thing... What you want to do is to have the switch set in a single broadcast domain (all ports in the same VLAN), right? If so, follow these steps:

  • Disable the routing features with the configuration command global "don'tno ip Routing.
  • If the first command is not accepted, type the "No dsm prefer lanbase-routing.

  These two steps above to disable the routing features.

  OK, to mark all the ports of the members of the same VLAN, you have a few options:

  • You can leave all the default ports VLAN (VLAN 1)
  • Or, you can configure all ports in another VLAN different
    • switchport mode access
    • access switchport vlan id - vlan>

  Hope this is useful for you.

  Hello

  You see it here. It is expected if you use this command.

  How to see he uses 'show interface running x/x' and see if configuration commands are there, or if there is already a device on the port if you use the command 'show the interface of the x/x authentication session' and see if the vlan comments is used or not.

• Reviews for iSCSI NFS e 3100 & Catalyst 2960-S vs?

  I'll put up my first SAN, a 3100 e with 2 NICs by MS.  We chose a pile of Cisco 2960-S for redundancy at the network level, and during the planning phase, I had chosen to use NFS.  E does not deduplication with iSCSI support (someone?), and the performance is roughly equal to this environment.  It is 3 guests with approximately 15 production MV; I expect a usage rate of 20% per host based on statistics collected from the current production environment.

  The glitch is 2960-S is limited to 6 ports-channels, even in a pile!  Initially, my plan was simple enough, and a commercial engineer.  Create channel-port on each host to storage traffic and traffic VM vMotion/HA.  Each of them would be 2 gigabit NIC in a VLAN dedicated.  But, now that I have that 6 Channel ports to work with, what is the best solution?  I would go with NFS, if possible, but I can't understand a good way to provide a high availability and balancing at the network level (yes I know that the effectiveness of IP hash is questionable in a port channel).

  In the past, I have Setup iSCSI multipathing in environments of test with good results, but it is a little more complex that I want to get for such a small environment, and we lose deduplication.

  Is back to the original question - possible to NFS, highly available, without aggregation of links?  I am referring to each element of the stack - host, network and SAN.  Is there another method would you recommend, and if so, why?

  A few thoughts I had:

  Wouldn't be better to put the vMotion/HA NIC on access ports with 1 NIC in standby mode and use the port for NFS instead channels?  Once the environment is fully migrated, I expect vMotion will be made during failures and maintenance periods.

  If I assigns an IP address to a store NFS SP A and it fails, MS B will remain passive until a failure and then take control of this IP/action?  Or the store NFS appears twice in my list of data stores?

  Thanks for your comments!

  Here is my attempt at bad taking a picture to help visualize this

  I had to redact the names and IP addresses

  MGMT use vmnic1 as a primary vmnic5, as a backup. It is the VLAN 125

  vMOTION uses vmnic5 as a primary vmnic1, as a backup. It is 126 VLAN.

  vmnic1 and vmnic5 are shared resources at the level of the physical switch to allow the 125 & 126 VLAN.

• Switch Cisco 2960/3560 = > recovery password and default settings with the button Mode

  Hi Experts,

  I have some confusion with the button Mode with cisco 2960/3560 switches.

  I read on many forums and articles, but where things are not clear.

  a place given 3 seconds and somewhere is given 7 or 10 seconds.

  Qus1), what is the exact time to press/hold Mode button to perform two following tasks:

  A. password recovery (according to my knowledge 3 sec) good or bad?

  Configuration of the switch (start + run) would be safe

  After the recovery of password? Yes or no

  B. factory default (according to my knowledge 10 dry) good or bad?

  I'm afraid, because if I press mode button more than 3 seconds, then

  It will delete any configuration of cisco switch. Yes or no

  Qus2) I want to recover the catalyst 2960/3560 switch password without

  Start/run configuration to lose. That is my main concern.

  Please tell me how to do this, what will be the time keeping Mode buttom

  in a few seconds?

  Qus3) which means this line

  "If the password recovery mechanism is disabled in switch

  then you will lose all the config.

• How to build a redundant fiber optic ring

  Hello everyone. I would like to connect 10 buildings with a redundant fiber optic ring and have a control to connect to the closet room build you on the ring to receive data from our process control systems located in the buildings of the ring. These are domain controllers systems that feed information to the bacbone on FTES. Can someone tell me a document that shows what I have to do and an example of architecture. We use S Catalyst 2960 switches or do I me 3750 s in all my buildings. Thanks in advance for any help.

  Hi Carroll,

  as L2 VLAN and VRF on L3 suggested donation is the best option to go with multiple isolated logical networks on a physical network

  Take a look at the link design guide for the isolation of path by using virtual and VRF LANs which below is very useful

  How to make a call from CPO to vCO (vcenter orchestrator)?

  Hello

  I am trying to create a workflow that would connect to a vCO.

  I was Expecting

  1. how to create targets for the vCO and

  2. how acess that target.

  Concerning

  Shiva

  1) there is no target for the vCO. We have a target/connection to Virtual Center (vCenter)

  (2) If you want to make vCO calls you could do, it all depends on how the API is structured. You can make calls via web services or CLI, etc.

  If you give your use case it is perhaps more to discuss. If you need an ENH or put something in, you can open a case with the TAC.
