Cisco Switching/Routing :: Nexus 7000 And 2000 FEX Support With VPC
Apr 20, 2012if 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.

Oct 15, 2012I am designing a network for my client where I have to implement a 10 Gig end to end connectivity. The major factor of concern from my management is about scalability (space to include more 10Gig servers as the nodes grow up). I have suggested Cisco 5596UP with 2232 PP as this gives ample amount of 10Gig ports. The setup has to be implemented across 2 different datacenters located 40 Kms apart, connected with 10Gig DC Interconnect.
I understand that Cisco Nexus 2232 is a Layer 2 Only switch and would need to communicate with parent 5K switch very frequently. Is it necessary to have the 2K and 5K pair in the same datacenter or in proximity? Is it possible to have the SFP uplinks connected to the DC interconnect? Because we have two datacenters located 40 Kms apart and having 1*Layer 3 - 5K switch at DC A with Layer 2 - 2K nexus Switch at DC B will be cost effective. We do require more 10Gig ports and not much requirement on Layer 3 usage. What are the type of communication that would be much frequent between 2K and 5K?

As you can see, the default group configuration ACS5-1 for authenticatoin has applied to both defaults and console. But the command authorization does not appear to be applied to the console. As a result, when i login from the console and get authenticated, the command authorization does not trigger and i can run commands I'm not supposed to. In the configuration, I do not see "aaa authorization console" option unlike we have in IOS.

Cisco Switching/Routing :: FIB Inconsistency On Nexus 7000
Aug 3, 2011On 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.

Jul 17, 2012I 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.

View 4 Replies View RelatedCisco Switching/Routing :: Nexus 7000 QoS Marking For Both DSCP And COS
Jan 29, 2012I 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 RelatedCisco Switching/Routing :: QOS For VOIP Traffic On Nexus 7000
Mar 4, 2012regarding 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

Cisco Switching/Routing :: Nexus 7000 Span Limitation
Apr 18, 2012I'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 ?
