I am running ping between two Nexus 7018 over WAN link ,and I can see some set pattern of packet drop(7.40 % drop) with MTU size 1500.When I ping between my 6500 VSS pair and same Nexus 7018 over different SP WAN link on diffrent location , I am still getting same kind of packet drop (8% drop) with MTU 1500. Has any one else come across this issue with Nexus?

I'm going to replace a Cat6513 with a Nexus 7018. In my Cat6513, there are object tracking config as follows:
ip sla monitor 1
type echo protocol ipIcmpEcho 112.78.254.249
timeout 3000
frequency 6
ip sla monitor schedule 1 life forever start-time now
ip route 172.17.7.0 255.255.255.0 165.202.51.46 name VPN-1 track 123
Is there similar feature in Nexus platform? Because from Nx-OS command ref, I only found:
ip route ip-prefix/mask {[interface] next-hop} [preference] [tag id]
Seems can't associate a track object to a static route in Nx-OS?

We have a Nexus 7018 with NX OS 5.2(1), and we were trying to understand somehow the steps to do a VACL, we know that in IOS it would be:
interface GigabitEthernet9/33
description Puerto. Captura
switchport
switchport trunk encapsulation dot1q
switchport trunk allowed vlan 19,20

I have a serious problem with nexus 7018, there're unicast flooding on one n7k, named n7k-1, which is the member of vPC domain combined with 2 N7Ks. [code]I had clean the mac-address-table, and all mac-address-tables had been synced fine, and the unicast flooding went away.
How could I fix the mac-address sync function between the modules ?

We are in a process to replace our old end of life switches( mostly Cisco 2950's) with some new offerings from cisco. Attached is our current network diagram. Anny merit of using Cisco Nexus switches in this design and also what will be the benifit in doing so. Again I am asking about the specific benefits which I will get in my Network not general benifits of nexus.

We have two Nexus 5010 to test the solution. As part of the testing we upgraded the boxes from 4.2.1.N1.1 to 5.0.2.N1.1 and after the reboot the switch lost all of the VLANs. We put the VLANs back and when we got to the private VLANs we got the following error:
%PRIVATE_VLAN-2-PVLAN_ASSOC_UP_FAILED: Failed to bring up the association between 530 & 531

I need to upgrade my core switches at one of our locations (two 7009s with dual sups) from 6.0.1 to 6.1.2. After looking through the release notes it appears that this will be a disruptive upgrade?how long should I expect for the disruption? Are we talking a 7009 boot cycle (10 - 15 minutes) or something longer?How many disruptions can I expect? I suspect 1 per chassis during the failover to the standby but I'd like to validate.Is there any compelling reason to upgrade the EPDL? From what I can see, again from the release notes, this is only necessary with F2 cards if I were to upgrade to Sup2s . I'm in a healthcare environment and this upgrade will be affecting one of our major campuses so the more info I can get to the managers the more accepting they will be for the disruptions.

I would like to perform nondisruptive upgrades on two Cisco Nexus 5010s that currently run NX-OS version 4.1(3)N2(1) to Release 5.1(3)N2(1a). Is this possible? Or, do I need to upgrade to Release 5.0(2)N1(1) first?

I have a situation where my Internet edge routers learn 0.0 from ATT (AS 7018) my provider. I then wish to advertise these learned routes via WAN. However my WAN MPLS provider is also ATT and they use AS 7018 for that as well. When I try to push 0.0 to my other WAN sites 0.0 is suppressed to avoid loops.What's the best way to tell the WAN routers to advertise 0.0 back to the same AS originally learned from?

I need to enable vPC "peer-switch" command on a pair of Nexus 7018s which are currently vPC peers (primary and secondary). The STP root and Secondary root are currently configured across these switches.Can I enable the peer-switch command in this configuration without impacting services, and then modify both switches to have the same bridge priority without impacting services ? We have a few downstream 5ks which are not dual homed to both vPC peers (work in progress) so need to understand if the peer-switch command will in any way break this connectivity for now.

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

we are planning a Nexus datacenter project with this layout:Our experiences with Nexus switches are not so large until now and the manuals are very extensive.Both N5K´s should be connected directly with all 4 N2K switches. I did not find a layout like this in the manuals. Only a design,where only 2 N2K are connected to one N5K, with this fex config:Now I´m not sure if it is right to make a config like this with the same slots and fex´s or with different slots and fex´s.

I have two Windows 7 computers and neither one will successfully upgrade a 1242 AP to LWAP. However, I go to a coworker's XP machine and run the tool without issues. On Windows 7 I keep receiving the error message of ACL or Firewall is blocking. I have added rules and then even tried disabling the firewalls completely on both computers and still no success.

Is it possible to upgrade the CSACS-1121-UP-K9 to be a non upgrade part? We were going to upgrade from a Windows 4.x to the above Appliance (version 5.x) but there is now a reason to keep the old Windows version running therefore we cannot give the new Appliance the old ACS's licenses?!So we should have (with hindsight) bought a fresh version of the ACS 5.x rather than an upgrade.
