which does not match reality : No one was configuring Vlans.

I have been tasked to replace the existing Cat 6500 and 3750 switches by Nexus 7000 and Nexus 2000.I was told initially my boss plans to get 2 x Nexus 7000 and then eventually blow up to 4 x Nexus 7000s.For Nexus, is there a list of tasks / points that i need to consider for building the initial design?
Can i just link the Nexus 7000 like the following?
N7k-A ========= N7k-B

lots of N2ks lots of N2ks

I config LMS to manage many network devices with the same credential. However, only the Nexus 7000 fail to be archive configuration. LMS log said during telnet, the authentication fail 3 times. (I didn't use any authen server. The username and password are local. and in DCR page, i only configure " Primary Credential"l, nothing in "Auto Update Credential")Then i do a CAD check and fail also. I open the RME/CAD log, comparing with those successful log, there is one line different:[ Mon Mar 05 16:04:27 SGT 2012 ],WARN ,[main], com.cisco.nm.rmeng.inventory.cda.CdaFacade,getCdaHandlerIf, 163,CdaAG is not implemented for the device145.240.152.1 What does it mean "CdaAG is not implemented for the device?

I work in an organization where we recently upgraded our core switches to Nexus 7000. Everything is set up well but we still keep getting this annoying message when we log in the switch. Also the time taken to login into the switch (ssh and telnet) is longer than normal. It is not affecting the network in any way but my concern is somewhere something is wrong and it will give us trouble in the future. How to troubleshoot the cause of this error message. [code]

On a 7K (5.0(2)), I have a situation where the FIB and RIB are out of sync. I'm not sure it's causing a problem, but it's been implicated in some weird packet loss issues. It seems like it could cause network issues if you had two routes in the RIB, only one in the FIB, and then you lost the single path in the FIB. How the RIB/FIB gets out of sequence, how to proactively know about it (nothing in the logs here), and whether or not this is a big deal or a red herring?
Here's sample output that illustrates the RIB and FIB being out of sequence.
ROUTER1# show ip route 172.16.100.1
IP Route Table for VRF "default"
'*' denotes best ucast next-hop

We recently purchased a pair of 2232TM Fabric eXtenders just to find out that our Nexus 7000 does not support it. Will there be support for the 2232TM FeX in Nexus 7000 any time soon?

I have two data centres connected via a L2 DWDM, my manager wants to look into using OTV to get rid of the layer 2 broadcasting issues.
Problem is the DWDM is 1000BaseSX, which is only supported on the N7K-F132XP-15. (and the N7K-M148GS-11 but that doesn't support FCOE, so many bloody caveats). From what I can gather OTV is not supported on the N7K-F132XP-15.
Is it possible to terminate the DWDM on the F1 card & loop another port from the F1 to a port on the N7K-M148GT-11 & run OTV on the M1????
Either using VDCs or just an isolated VLAN on the F1. Is there any better way to do this? Hardware has not yet been purchased.

I am seeing an issue that after deleting/recreating one of the VDC in Nexus 7K, VLAN is not been able to be configured within the VDC although it is not actually a reserved VLAN. Could it be anything missing in the license installation? the version of the image is NX-OS 6.1.2
StorageVDC(config)# vlan 100
^
invalid vlans (reserved values) at '^' marker.

I have a pair of Nexus 7K's running 5.1(3). I have a handful of edge devices that I need to mark ingress traffic, and need to mark both DSCP and CoS. Right now, I have a working config that marks DSCP appropriately.While that works dor DSCP, the MQC will not allow me to mark both DSCP and COS in the same class, and unlike IOS, it appears that Nexus does not have a default DSCP-to-COS mapping. My understanding is this can be solved using table maps, but I don't see how that can solve my problem in this specific scenario (it appears I can do marking or table-map mutation, but not both?). How I can accomplish both?

I need to know how is the ambient temperature for the Nexus 7000 switches to plan a new datacenter. In the datasheet I found the following information regarding this topic:"GR-63-CORE Network Equipment Building Standards (NEBS) specification published by Telcordia Technologies in Section 4.1.2". How are the specification for temperature in this standard?

regarding QOS on Nexus 7000. Our Nexus 7000's form a collapsed distribution/core layer, our access layer switches are are a mixture of Cisco 3750 & Cisco 4507. 3750 switches will connect to Nexus switches via 1Gb uplink, 4507 switches will connect via 10Gb uplinks. Each Nexus will be connected via 20Gb port channel, all servers connect to the Nexus switches via 1Gb links. We're implementing a new telephone system soon which will be using VOIP so I need to configure the switches to perform QOS. The IP phones will mark the RTP traffic with DSCP value EF and call signaling traffic CS3. I'm fine configuring qos on the access layer switches, its just the Nexus switches which I'm not sure about.
Do I actually need to configure any QOS parameters on the Nexus switches so they will prioritise the VOIP traffic. If my understanding the Nexus switches will trust the DSCP values and assign the traffic to the relevent queues?
Just for information VOIP is the only traffic I will be marking QOS values

On Nexus 7000s I want to limit bandwidth of particular IP. I can do this using proper configuratio of IP ACL, policy map and class map. But what if I dont have information on interface? Can I apply bandwidth control for particular IP without knowing the interface?

if vPC is supported between a single 2232PP FEX and two 7000 switches running 6.0(1)? I have been researching this for an implementation I am doing for a client and was able to determine it was not supported with earlier versions of 5.0 when the FEX is connected via vPC as I described above, but I can't find anything related to version 6.0(1). I have done this for other clients with 5000 and 2000 switches, but I don't have too much experience with 7000 switches.

I have some error messages in the Nexus 7000 log, after searching i cannot find an adequate explanation, pretty much the only thing i can find is below and i don’t think it is very relevant to my situation. The device is in production and so reloading and pulling card willy nilly is the last resort.
Device = Nexus 7018
IOS version = 5.1(2)

I've learned recently that the Nexus 7000 only allows the configuration of a maximum of 2 Monitor sessions for spanning traffic. I only have one monitor session left and I need to do the following. 2 Core Nexus 7000 boxes with 2 different traffic probes/sniffers to each nexus( eg Sniffer 1 connects to Switch A on interface eth 1 and to Switch B on eth 1 ; Sniffer 2 connects to Switch A on eth 2 and to Switch B on eth 2.) My plan was to setup a standard session with multiple sources and destinations then on the interfaces connecting to the sniffers run a trunk and do 'sw trunk allowed xxxxx' and filter what I need to go to each sniffer box. However I've recently found out that some of my source traffic is coming from Port-Channel interfaces. Is there a way I can get around this and still do the filtering within only 1 monitor session ?

Are there any dependencies on VTP on the Nexus platforms like the 5500 or 7000? In IOS P V LAN required VTP Transparent mode however I cannot find any reference to this for the Nexus platform. Are there any other features that would require the use of VTP? By default VTP is turned off on nexus and has to be enabled with the feature command so is there any benefit to running VTP in transparent mode vs off?

ive tried this for port eth 4/1:
bciscon7k01(config)# int eth 4/1,eth 4/3,eth 4/5,eth 4/7
bciscon7k01(config-if-range)# shut
bciscon7k01(config-if-range)# int eth 4/1

I have a Nexus 7000 pair with Etherchannels connecting to various access switches. 2960's and 3750's.The access switches channel 2 ports together. LACP active mode. One link goes to one Nexus and one to the other. Those connections are a portchannel with vpc configured.Every 30 seconds on every interface connecting to one Nexus I see a FCS error. The errors increment at the same time every 30 seconds. Only on one port. If I shutdown that link and keep the channel up on the other link the errors move. No shut the interface and they move back.This must surely be some Nexus generated packet that the access switch does not recognize/ what is likely to be getting sent at 30 sec intervals to all Channel members on one link ?
