• Cisco Nexus 1000V Virtual Switch Module investment series in the Cisco Unified Computing System

  Hi all
  I read an article by Cisco entitled "Best practices in Deploying Cisco Nexus 1000V Switches Cisco UCS B and C Series series Cisco UCS Manager servers" http://www.cisco.com/en/US/prod/collateral/switches/ps9441/ps9902/white_paper_c11-558242.html

  A lot of excellent information, but the section that intrigues me, has to do with the implementation of module of the VSM in the UCS. The article lists 4 options in order of preference, but does not provide details or the reasons underlying the recommendations. The options are the following:

  ============================================================================================================================================================
  Option 1: VSM external to the Cisco Unified Computing System on the Cisco Nexus 1010

  In this scenario, the virtual environment management operations is accomplished in a method identical to existing environments not virtualized. With multiple instances on the Nexus 1010 VSM, multiple vCenter data centers can be supported.
  ============================================================================================================================================================

  Option 2: VSM outside the Cisco Unified Computing System on the Cisco Nexus 1000V series MEC

  This model allows to centralize the management of virtual infrastructure, and proved to be very stable...
  ============================================================================================================================================================

  Option 3: VSM Outside the Cisco Unified Computing System on the VMware vSwitch

  This model allows to isolate managed devices, and it migrates to the model of the device of the unit of Services virtual Cisco Nexus 1010. A possible concern here is the management and the operational model of the network between the MSM and VEM devices links.
  ============================================================================================================================================================

  Option 4: VSM Inside the Cisco Unified Computing System on the VMware vSwitch

  This model was also stable in test deployments. A possible concern here is the management and the operational model of the network links between the MSM and VEM devices and switching infrastructure have doubles in your Cisco Unified Computing System.
  ============================================================================================================================================================

  As a beginner for both 100V Nexus and UCS, I hope someone can help me understand the configuration of these options and equally important to provide a more detailed explanation of each of the options and the resoning behind preferences (pro advantages and disadvantages).

  Thank you

  No, they are different products. vASA will be a virtual version of our ASA device.

  ASA is a complete recommended firewall.

• Cisco Nexus 3548/3524 SNMP Interface traffic problem

  Hi all!

  I would like to share with you the problem I've encountered SNMP interface respect tracking on the Cisco Nexus 3500 of traffic devices.

  We is transferring our network infrastructure in the Nexus and we encountered a problem with the interface bitrate of tracking traffic on Nexus 3548: deltas SNMP counter ifHCInOctets and ifHCOutOctets show no valid data.

  We have investigated this issue and figured he could be linked with the refresh rate of the meter.
  I measured, by snmpwalk, the time between simple increments the counter ifHCInOctets to Interface VLAN and it apears to about 140seconds. But for physical interfaces (Eth), the interval of interface SNMP counters are 15 seconds and with sampling frequency of the 1960s for the queries we can still observe the problems on graphs (see attached screnshot).

  We get the same results when testing the question on various physical devices (3548 Nexus) on versions of different software - including the last being.

  snmpscreenshotvlanint.jpg

  

  And for Ethernet interfaces (same NMS - ZABBIX-config):

  snmpscreenshotphint.jpg

  

  We tested a wide Huawei s6700 switches and the range of Cisco IOS devices and there is no such problems.

  The main problem is that we cannot monitor our crucial nexus, via SNMP devices (as you can see from the attached chart).  Results are the same when configure us Cacti or Zabbix to monitor Nexus devices.

  The results of this monitoring not having meritorical value or use.

  We are working on this case with Cisco TAC, and they manage to reproduce the problem in their LAB environment. But for now, they cannot provide any solution and they claim that this isn't a bug. If we get any final statement for this case, I'll post here for your information.

  I'll be more than happy if you can post ideas that help me solve the problem described.

  Thank you in advance!

• Cisco Nexus 1000v switch

  Hi, I have 2 questions about the Switch Cisco Nexus 1000v.

  First of all, why use it rather than the standard vswitch distributed?

  Second, if an environment currently works using distributed vswitches, what are the impacts and the problems likely to introduce a Switch Cisco Nexus 1000v? Is there a process for the upgrade?

  See you soon

  Here is a comparison for the most up-to-date between the optioins network:

  http://www.Cisco.com/en/us/prod/collateral/switches/ps9441/ps9902/solution_overview_c22-526262.PDF

  The great driver with most of the people running the 1000v I talked to is give visibility to the network team and streamlining changes made to the virtual network environment. In a great organazation with a network operations team, they will create an IVR to route a new VLAN, and then create the new VLAN on all switches distribution and access in the area of layer 2, just 1000v allows them to move forward and it create on the hypervisor using a set of commands that they already know.

• 40g of Cisco Nexus-FET

  I'm trying to choose the right cable to connect to a Cisco Nexus 40 G - FET (on a Nexus 6004). I saw on Cisco's Web site that says the FET transceiver has 12 fibres inside. Yet, when he broke out to connect to four FETs of 10G on a FEX (2232TM-E), only 8 fibers would be used.

  so... What type of connector DFO buy? A 12 FTU fiber or fiber 8 FTU? Are they interchangeable? I might as well use an 8 or a connector DFO 12 fiber on my fan-out cable?

  Cisco uses 8 fiber lit even if standard DFO is of 12 fibers. Please refer to Figure 23 here.

  As described further down in this document (figures 25 and 26) some (cited Corning) providers offer only fiber 8 DFO and which can be used for interconnection as well.

• Switch Cisco Nexus 6004 removes more than 300 bytes IP packets

  Hi all

  We have a circuit of wave level 3 10 G running between two switches Cisco Nexus 6004. The circuit came online between our two data centers (in the same city) without problem.

  When attempting to ping to the remote-end 10G interface, it works very well with packets of 64 bytes. CDP is enabled and that we see the CDP information remote switch. However, if we increase the size of the ping to more than 300 bytes packets, we lose 1 in every 20.

  We settings MTU verifed, type of cable of 10G and duplex settings.

  Level 3A tested clean and we will move forward with more testing.

  Any ideas on the problem? We feel the carrier out and end to test with their testers. But so far, the circuit's own test. I was not sure if it is something related to Cisco. I am at a loss at the moment.

  Thank you.

  Mike

  Hi Mike,.

  There is nothing wrong with your switches or circuit.  NEXUS devices have a default COPP on the control plan that limit the size and the amount of traffic that must be the CPU process.

• Cisco Nexus to use authentication Radius AAA using Microsoft 2008 NPS

  I have a Nexus 7010 running

  I was wondering if you can help me with something. I'm having a problem with the approval of the order through our aaa config. We have not an authentication problem of command approval that does not work. From what I've seen and read Nexus NX - OS 6.x has not all orders for the aaa authorization, unless you configure GANYMEDE +. My basic config is below if you can help would be much appreciated.

  > ip source interface mgmt radius 0

  > key RADIUS-server XXXXX

  > host X.X.X.X key radius server authentication XXXXX accountant

  > RADIUS-server host X.X.X.X XXXXX key authentication accountant aaa

  > authentication login default group aaa authentication Radius_Group

  > RADIUS server logon group console local aaa Radius_Group

  > server X.X.X.X

  > server X.X.X.X

  > mgmt0 interface-source

  Also nobody how to configure Microsoft 2008 NPS as Raduis server to work with Nexus? I read a few post that suggests to change the

  Shell: roles = "vdc-admin" in the value field of the attribute in the RADIUS server

  Anyone know if it works?

  Thank you

  I haven't used NPS before but sounds like you are on the right track. As Ed mentioned in his post, GBA, you can set the type of protocols that you will accept during an authentication session. Authentication Nexus sessions is considered as PAP/ASCII, so you should be good to go. I don't have a Nexus switch to test with, but if you can use wireshark to capture the session and see the exact protocol / method used. However, I am sure that PAP is the way to go:

• Cisco Nexus switches

  I'm looking to deploy a series 5100 Cisco NEXUS switch at 10 Gbps.

  I know that the Nexus is supposed to work with the converged network adapter (for 10 Gbps FCoE, etc.), but can it operate without an ANC?

  I want to put some passthrough 10 Gbps modules in my Dell m1000 chassis and the cables directly to the Nexus switch.

  I know that the Nexus is perhaps overstated for this solution, but it is a step in the UCS solution for us.

  Thoughts?

  Hi, you don't need special drivers for "low latency" 10 Gbit ethernet on a 5 k.

  for example, to switch non-nexus 5 k

  PING 10.10.10.1 (10.10.10.1) 56 (84) bytes of data.

  64 bytes of 10.10.10.1: icmp_seq = 1 ttl = 255 time = 0,530 ms

  64 bytes of 10.10.10.1: icmp_seq = 2 ttl = 255 time = 0.618 ms

  and a nexus 5000 with a qlogic 8152

  PING 172.16.78.3 (172.16.78.3) 56 (84) bytes of data.

  64 bytes from 172.16.78.3: icmp_seq = 1 ttl = 128 time = 0.150 ms

  64 bytes from 172.16.78.3: icmp_seq = 2 ttl = 128 time = 0,134 ms

• Configuration of Cisco Nexus

  Hi, wondered about the Configuration of the Cisco Nexus 100v.

  First of all, the MSM will have three vNIC used to:

  1. the Control Interface - NIC1

  2. Management Interface - NIC2

  3 packet Interface - NIC3

  The management interface is on the same VLAN as VMconsole (service console) because it is used to communicate with vCenter and ESX hosts for management traffic?

  Addresses IP should be assigned for control and packet Interfaces?

  Thank you

  When you use L3 control we encapsulate the control traffic and the package on the default management interface. Only IP you need is the IP address that you have assinged to the management interface 0. Interfaces and control packets never get used and never need a IP address.

• help required for cisco nexus 1000v

  Hello

  I have three esxi host in my environment and I want to integrate these hosts with cisco nexus 1000v switch.

  I installed vsm on host1 and adding the remaining host via vsm Update Manager. exchanges I have already create in SMV shown in the welcome that I've added to the vsm, but the port group is not shown on the host1 esx on which I have installed vsm, should I also add the host that contains MSM in the cisco nexus switch?

  I want to say that I have installed the MEC on any army three esxi. is it good?

  Hi Mohsin,

  Where did you read that? In the past, we have added the guests, including one who executes the VSM. Usually run us both VSMs (primamry and secondary) and add anti rules affinity so that the two VSMs are on different hosts. I'm not a person CISCO, but having worked with CISCO engineers, we had no problem with what you have just mentioned. It would really be a waste of host in my opinion. I don't see why this could be a problem... As long as you have all your trade (PGs for your packages VSM etc etc) in place, you should be able to add all hosts in my experience.

• Restoration of Cisco Nexus 1000V - Host-ID fingerprint

  Someone find some information about how to restore a Cisco Nexus 1000V?

  The license is the result of a fingerprint of the identifier of the VSM. In case we lose the VM with VSM or host ESX Server must be reinstalled, this print is different. So that would mean the licensekey need, it's be regenerated.

  Has anyone found information on it?

  R: Yes

• Cisco Jabber with Cisco multi-party Shared more Licenses

  Hello

  I'm looking for a Solution to video conference for approximately 4000 employees. Currently the customer uses Cisco's Jabber for video calls from point to point. The main requirement is Ad - Hoc videoconferencing by any employee at any time. I looked at both meeting of Cisco and Cisco TelePresence Server server. The two solution requires more or licenses more pluralistic multi-party Personal shared. The customer won't buy a PMP license for each user. Their requirement is multimedia resources shared so that any employee can initiate an ad hoc conference.

  Now the question is: can we use Cisco Jabber with multiparty licensing shared?

  Thank you

  Mockus S

  Yes, it is quite possible.

  The only singularity is with PMP + which applied slightly differently than the head of the Orchestra/vTS. This does not seem to match your use case since you intend to buy only SMP licenses +. From version 2.0 (1) CMS, PMP + licenses - which are less expensive than SMP + - use only if: a) the space belongs to a LDAP user with a PMP + license for which they are responsible; or (b) If a user LDAP with PMP + assigned to them joins the Cisco meeting App space as an authenticated user. In all other scenarios, including ad-hoc escalation with CUCM licensed SMP + is consumed. This is different from that of head of the Orchestra/vTS, which were also able to understand the right to the user for ad-hoc calls.
