i wanted to know if i can and when i will be able to run the nexus 7000 as a Fully MPLS PE router (L2VPN, L3VPN etc..) ?
the interfeces need to be 10Gbps so i need to use the 8 ports & the 32 ports M1 modules.
I installed mpls feature set in N7K.I was able to enable feature l3vpn.Then, I tried enabling feature ldp. license not installed. ldp feature will be shut down after grace period of approximately 120 day(s).
I don't see any TRANSPORT_SERVICES_PKG in the NX-OS licensing guide.However, there is LAN_TRANSPORT_SERTICE_PKG. But I believe this is not for LDP.
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

I just bought 2 Nexus 7000 to upgrade my primary/Production Data Center from 6509/MSFC. I'll keep the 6509E/SUP720 for the DR Data Center. I have ordered two 10Gig Wan Pipes between the Production and DR. In other words between the Nexus 7000 and the 6509E.
My problem is that i do not know the best way to do the routing between the 2 Data Centers. Currently I have MPLS with a provider connecting the 2 Data Centers using BGP on the CEs and I'm running eigrp in locally in the Cores. After the 10Gig comes to life, the MPLS will go away.
My QUESTION: Should i run ibgp between the 2 Nexus and ibgp between the 2 6509E/sup 720 AND THEN run ebgp between the Nexus and the 6509/sup 720 over the 10Gig WAN? OR should i collapse everything into one eigrp domain/AS and just run Eigrp between the Nexus and 6509E/Sup 720 over the 10Gig Wan?
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]

I am working on a DataCenter architecture where we would like to implement Nexus 7000, For the time being, there only one "context" but we may take the opportunity to implement VDC in a later future, I was not able to find a clear answer on the following :
Can we add the VDC licence & configure a new VDC on a Nexus 7000 running without VDC ? I suppose this is possible. but does it need to have the whole configuration changed or adding a VDC can be done without any interruption on the current environnement ?
We have Nexus 7000s configured for sampled netflow. We have tools that should reconstruct the sampled flow records for management displays. Most tools require the flow record, option and template to be sent in order to reconstruct the sampled flow record. We have captured some of this traffic and noticed that the template contains "SamplerMode": Unknown (1) [See Nexus 1-1.png]. Is this usual or have we not include commands required for proper operation? [code]

Using 2 different flow collectors (open source and commercial), gaps/drops in the reported traffic are observed on a periodic basis.Problem doesn't seems to be with the exporters, hence I wondering if netflow configuration on N7K can be tweaked to address this symptom.

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.

View 4 Replies View RelatedI 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

View 1 Replies View RelatedI 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?

View 1 Replies View Relatedregarding 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
