NEXUS 7000 xcvrInval

Hi,
I have some Nexus 7000 with FET-10G with xcvrInval status
Eth7/33          N5k-S1-3T-1/3   xcvrInval trunk     auto    auto    Fabric Exte
and some other FET-10G with notconn status
Eth7/8           FEX-101         notconnec 1         auto    auto    Fabric Exte
If I inter exchange the position of both FET-10G the status port doesn´t change
FET-10G from 7/8 to 7/33
FET-10G from 7/33 to 7/8
7/33 holds xcvrInval status
7/8 holds notconnec status
I have reconfigured from default interface with same results
Next you´ll find the same serial number in deferent port, the diference is the current
when is xcvrInva or when is notconnec
What can I do to get FET10G in e7/33 validated?

Nexus 7000 Platform Logging

Hello,
We recently had a power supply failure in one of our Nexus 7000s, and I noticed that the syslog for the Platform is only present in the default VDC, and not in any of the other VDCs syslogs. Is this by design, or is there a logging level I can turn up in another VDC to capture this log? Thanks for any input
syslog from default VDC -

Hello Carl,
What version of code are you running on your Nexus 7k?
The expected behavior is:
"When a hardware issue occurs, syslog messages are sent to all VDCs."

Dell Servers with Nexus 7000 + Nexus 2000 extenders

<< Original post by smunzani. Answered by Robert. Moving from Document section to Discussions>>
Team,
I would like to use some of the existing Dell Servers for new network design of Nexus 7000 + Nexus 2000 extenders. What are my options for FEC to the hosts? All references of M81KR I found on CCO are related to UCS product only.
What's best option for following setup?
N7K(Aggregation Layer) -- N2K(Extenders) -- Dell servers
Need 10G to the servers due to dense population of the VMs. The customer is not up for dumping recently purchased dell boxes in favor of UCS. Customer VMware license is Enterprise Edition.
Thanks in advance.

To answer your question, the M81KR-VIC is a Mezz card for UCS blades only. For Cisco rack there is a PCIe version which is called the P81. These are both made for Cisco servers only due to the integration with server management and virtual interface functionality.

Ask the Expert: Basic Introduction and Troubleshooting on Cisco Nexus 7000 NX-OS Virtual Device Context

With Vignesh R. P.
Welcome to the Cisco Support Community Ask the Expert conversation.This is an opportunity to learn and ask questions of Cisco expert Vignesh R. P. about the Cisco® Nexus 7000 Series Switches and support for the Cisco NX-OS Software platform .
The Cisco® Nexus 7000 Series Switches introduce support for the Cisco NX-OS Software platform, a new class of operating system designed for data centers. Based on the Cisco MDS 9000 SAN-OS platform, Cisco NX-OS introduces support for virtual device contexts (VDCs), which allows the switches to be virtualized at the device level. Each configured VDC presents itself as a unique device to connected users within the framework of that physical switch. The VDC runs as a separate logical entity within the switch, maintaining its own unique set of running software processes, having its own configuration, and being managed by a separate administrator.
Vignesh R. P. is a customer support engineer in the Cisco High Touch Technical Support center in Bangalore, India, supporting Cisco's major service provider customers in routing and MPLS technologies. His areas of expertise include routing, switching, and MPLS. Previously at Cisco he worked as a network consulting engineer for enterprise customers. He has been in the networking industry for 8 years and holds CCIE certification in the Routing & Switching and Service Provider tracks.

Hi Vignesh
Is there is any limitation to connect a N2K directly to the N7K?
if i have a an F2 card 10G and another F2 card 1G and i want to creat 3 VDC'S
VDC1=DC-Core
VDC2=Aggregation
VDC3=Campus core
do we need to add a link between the different VDC's
thanks

LMS 4.2.2 Interface utilisation on Nexus 7000

Hi All,
I'm trying to poll some interfaces for their utilization on a nexus 7000 through LMS 4.2.2.
When I create a poller fot the specific instances, the LMS recognises the instances, but after activating the poller I get the error "No Such Instance - The specified instance is not available".
No info is displayed when I generate an interface utilization report for the specific nexus.
When I activate the automonitor for interface utilization, the interfaces on the nexus are polled.
On the cisco website there are some features listed which LMS does not support on the Nexus 7000, but polling is not in that list (neither in the supported feature list).
Any tips?
Thanks for your help.

Any Idea..??

ESXi 4.1 NIC Teaming's Load-Balancing Algorithm,Nexus 7000 and UCS

Hi, Cisco Gurus:
Please help me in answering the following questions (UCSM 1.4(xx), 2 UCS 6140XP, 2 Nexus 7000, M81KR in B200-M2, No Nexus 1000V, using VMware Distributed Switch:
Q1. For me to configure vPC on a pair of Nexus 7000, do I have to connect Ethernet Uplink from each Cisco Fabric Interconnect to the 2 Nexus 7000 in a bow-tie fashion? If I connect, say 2 10G ports from Fabric Interconnect 1 to 1 Nexus 7000 and similar connection from FInterconnect 2 to the other Nexus 7000, in this case can I still configure vPC or is it a validated design? If it is, what is the pro and con versus having 2 connections from each FInterconnect to 2 separate Nexus 7000?
Q2. If vPC is to be configured in Nexus 7000, is it COMPULSORY to configure Port Channel for the 2 Fabric Interconnects using UCSM? I believe it is not. But what is the pro and con of HAVING NO Port Channel within UCS versus HAVING Port Channel when vPC is concerned?
Q3. if vPC is to be configured in Nexus 7000, I understand there is a limitation on confining to ONLY 1 vSphere NIC Teaming's Load-Balancing Algorithm i.e. Route Based on IP Hash. Is it correct?
Again, what is the pro and con here with regard to application behaviours when Layer 2 or 3 is concerned? Or what is the BEST PRACTICES?
I would really appreciate if someone can help me clear these lingering doubts of mine.
God Bless.
SiM

Sim,
Here are my thoughts without a 1000v in place,
Q1. For me to configure vPC on a pair of Nexus 7000, do I have to connect Ethernet Uplink from each Cisco Fabric Interconnect to the 2 Nexus 7000 in a bow-tie fashion? If I connect, say 2 10G ports from Fabric Interconnect 1 to 1 Nexus 7000 and similar connection from FInterconnect 2 to the other Nexus 7000, in this case can I still configure vPC or is it a validated design? If it is, what is the pro and con versus having 2 connections from each FInterconnect to 2 separate Nexus 7000? //Yes, for vPC to UCS the best practice is to bowtie uplink to (2) 7K or 5Ks.
Q2. If vPC is to be configured in Nexus 7000, is it COMPULSORY to configure Port Channel for the 2 Fabric Interconnects using UCSM? I believe it is not. But what is the pro and con of HAVING NO Port Channel within UCS versus HAVING Port Channel when vPC is concerned? //The port channel will be configured on both the UCSM and the 7K. The pro of a port channel would be both bandwidth and redundancy. vPC would be prefered.
Q3. if vPC is to be configured in Nexus 7000, I understand there is a limitation on confining to ONLY 1 vSphere NIC Teaming's Load-Balancing Algorithm i.e. Route Based on IP Hash. Is it correct? //Without the 1000v, I always tend to leave to dvSwitch load balence behavior at the default of "route by portID".
Again, what is the pro and con here with regard to application behaviours when Layer 2 or 3 is concerned? Or what is the BEST PRACTICES? UCS can perform L2 but Northbound should be performing L3.
Cheers,
David Jarzynka

Privilege Level for Tacacs Account in Nexus 7000

Hi,
I have configured the Tacacs (ACS 4.2v) on Nexus 7000 (as mentioned below) and works fine but unlike IOS (6509) It's doesn't prompt that you are in userexec mode (>) and then need to type enable and password for full privilege.
In n7k when I entered into "configure terminal" It won't allow me to access other commands.
How to login into level 15 privilege mode after authenticating from tacacs
(config)# show running-config tacacs+
tacacs-server key 7 "xxxxx"
tacacs-server host x.x.x.x key 7 "xxxx"
aaa group server tacacs+ TacServer
    server x.x.x.x (same ip as tacacs-server host)
    use-vrf management
    source-interface Vlan2
(config)# show running-config aaa
aaa authentication login default group TacServer
aaa authentication login console local
aaa user default-role
Here below are the commands accessible in "Terminal" currently
(config)# ?
no        Negate a command or set its defaults
username Configure user information.
end       Go to exec mode
exit      Exit from command interpreter
isb.n7k-dcn-agg-1-sw(config)#

Hi Jan.nielsen
Issue is resolved but by another way.
I have found the same resolution too of custom attirbute command but the Custom attribute Option for shell command wasn't available in ACS v4.2, so after enabling shell for users and by clicking exec--> Shell Exec and enabling priviledge level 15 in the same box of Shell options, It start working without any command

Nexus 7000 - unexpected shutdown of vPC-Ports during reload of the primary vPC Switch

Dear Community,
We experienced an unusual behavior of two Nexus 7000 switches within a vPC domain.
According to the attached sketch, we have four N7Ks in two data centers - two Nexus 7Ks are in a vPC domain for each data center.
Both data centers are connected via a Multilayer-vPC.
We had to reload one of these switches and I expected the other N7K in this vPC domain to continue forwarding over its vPC-Member-ports.
Actually, all vPC ports have been disabled on the secondary switch until the reload of the first N7K (vPC-Role: primary) finished.
Logging on Switch B:
20:11:51 <Switch B> %VPC-2-VPC_SUSP_ALL_VPC: Peer-link going down, suspending all vPCs on secondary
20:12:01 <Switch B> %VPC-2-PEER_KEEP_ALIVE_RECV_FAIL: In domain 1, VPC peer keep-alive receive has failed
In case of a Peer-link failure, I would expect this behavior if the other switch is still reachable via the Peer-Keepalive-Link (via the Mgmt-Port), but since we reloaded the whole switch, the vPCs should continue forwarding.
Could this be a bug or are there any timers to be tuned?
All N7K switches are running on NX-OS 6.2(8)
Switch A:
vpc domain 1
peer-switch
role priority 2048
system-priority 1024
peer-keepalive destination <Mgmt-IP-Switch-B>
delay restore 360
peer-gateway
auto-recovery reload-delay 360
ip arp synchronize
interface port-channel1
switchport mode trunk
switchport trunk allowed vlan <x-y>
spanning-tree port type network
vpc peer-link
Switch B:
vpc domain 1
peer-switch
role priority 1024
system-priority 1024
peer-keepalive destination <Mgmt-IP-Switch-A>
delay restore 360
peer-gateway
auto-recovery reload-delay 360
ip arp synchronize
interface port-channel1
switchport mode trunk
switchport trunk allowed vlan <x-y>
spanning-tree port type network
vpc peer-link
Best regards

Problem solved:
During the reload of the Nexus 7K, the linecards were powerd off a short time earlier than the Mgmt-Interface. As a result of this behavior, the secondary Nexus 7K received at least one vPC-Peer-Keepalive Message while its peer-link was already powerd off. To avoid a split brain scenario, the VPC-member-ports have been shut down.
Now we are using dedicated interfaces on the linecards for the VPC-Peer-Keepalive-Link and a reload of one N7K won't result in a total network outage any more.

Using SNMP to monitor Nexus 7000 Series Supervisor Module

I got a Nexus 7000 supervisor module recently, I met a SNMP problem for this module
I would like to know which specific OIDs to use to monitor the following using SNMP on a Nexus 7000 supervisor module:
- Port status
- CPU total utilization
- Power Supply status
- Chassis Fan status
etc.
The Nexus is quite different from other Cisco devices - any help will be appreciated!

hope help, and
port status OID is ifOperStatus

Query Nexus 7000 Enviroment Status

Hi,
I am trying to figure out how to query a Nexus 7010 Chassis about its enviroment. For our IOS Switches we use SNMP and OID 1.3.6.1.4.1.9.9.13.1 and the related sub OIDs. But this does not work on the Nexus 7010 with version 5.1. Is querying the information not supported or is there another OID?

Rule based span on Nexus 7000

Hi all,
I'm trying to configure rule based span on my Nexus 7000.
I want to monitor some vlans, but limit the traffic going to my monitor station by using frame-type ipv4 filter.
The link below explains how to configure it, but my nexus doesn't recognise the command "mode extended".
http://www.cisco.com/c/en/us/td/docs/switches/datacenter/sw/6_x/nx-os/system_management/configuration/guide/sm_nx_os_cg/sm_14span.html#wp1286697
Am I missing something? I'm running version 6.1.3.
Thanks,
Joris
NEXUS(config)# monitor session 1
NEXUS(config-monitor)# mode extended
^
% Invalid command at '^' marker.
NEXUS(config-monitor)# mode ?
*** No matching command found in current mode, matching in (exec) mode ***
connect Notify system on modem connection
restart Reenabling modem port

Hi Joris,
The rule based SPAN filtering was not introduced until NX-OS 6.2 so will not be available to you with NX-OS 6.1(3).
See the section SPAN in the NX-OS 6.2 release notes.

%ARP-3-DUP_VADDR_SRC_IP on two Nexus 7000 using HSRP

Hi,
I am receiving the error %ARP-3-DUP_VADDR_SRC_IP on two Nexus 7000 switch that is configured with HSRP. I only see this error when the Nexus performs a failover to the HSRP standby unit. I personally think this can be safely ignored,but wanted to get another opinion.
I can generate the error when i initiate the failover of several SVIs that are configured for HSRP. I do not see the error when failover doesn't happen.
I haven't been unable to find any documentation for Nexus on this error.
I have found documentation on this error for Catalyst switches and they seem to indicate a loop in the network. I can confirm that there are no loops in the network.
Has anyone else seen this happen on a Nexus? Any links to documentation would be great too.
Thanks

you have duplicate IP addres on some host connected to portchanel10
probably some access layer switch is connected to your portchanel 10
try to find port where this host is connected in access layer switch
sh mac addr | i ac8f
and dont forget to rate post

Log configuration changes to syslog on Nexus 7000?

I need to be able to log any configuration changes to syslog on our Nexus switches. On IOS this is easy with the archive commands, but I'm a little stuck trying to do this on our Nexus gear. On the IOS gear I run the commands:
archive
log config
logging enable
logging size 100
hidekeys
notify syslog
How do I do the equivalent on NX-OS?

Cisco NX-OS can log configuration change events along with the individual changes when AAA command accounting is enabled.
With command accounting enabled, all CLI commands entered, including configuration commands, are logged to the configured AAA server. Using this information, a forensic trail for configuration change events along with the individual commands entered for those changes can be recorded and reviewed.
Because of this capability, it is strongly advised that AAA command accounting be enabled and configured.
Refer to the “TACACS+ Command Accounting” section of this document for more information.
The Nexus 7000, by default keeps a local accounting log of all the configuration commands entered on the device; you can view this with the 'show accounting log' command.
In NX-OS, we changed the way logging works. We keep a local accounting log of all the
configuration changes ("show accounting log"), but if you want to send those logs to a
server, it must be done with through a TACACS server. Please see the below documentation:

Requirements about delay and bandwith for using OTV in Nexus 7000 between two data centers separated 25 miles?

We have two Nexus 7000, and I need use them with OTV between two data Centers separated 25 miles, but I don´t know what are the optimal values about bandwidth and delay (ms) for extended VLANs IDs (production and DAG replication) for Microsoft Exchange environment. Can somebody tell me please which are the values required for operate OTV in optimal conditions in this case? We have about 35 000 users that will use that platform of email. Thanks a lot for your comments. Regards.

GLBP on Nexus 7000's

We have GLBP configured on two Nexus 7000's using "load-balancing host-dependant" as our method of balancing. My question is, is there a quick way to determine which router each host is using. These are in production so any debugging is frowned on.
Thanks
David

Available command to verify GLBP operation is following
show glbp [group group-number]
Displays the GLBP status for all or one group.
show glbp capability
Displays the GLBP capability for all or one group.
show glbp interface interface-type slot/port
Displays the GLBP status for an interface.
show glbp interface interface-type slot/port [active] [disabled] [init] [listen] [standby]
Displays the GLBP status for a group or interface for virtual forwarders in the selected state.
show glbp interface interface-type slot/port [active] [disabled] [init] [listen] [standby] brief
Displays a brief summary of the GLBP status for a group or interface for virtual forwarders in the selected state.
But none of these will show you which host uses which AVF. In GLBP, Hosts still point to a default gateway IP address, but GLBP causes different hosts to send their traffic to one of up to four routers in a GLBP group. To do so, the GLBP Active Virtual Gateway (AVG) assigns each router in the group a unique virtual MAC address format 0007.B400.xxyy, where xx is the GLBP group number, and yy is a different number for each router (01, 02, 03, or 04). When a client ARPs for the (virtual) IP address of its default gateway, the GLBP AVG replies with one of the four possible virtual MACs. By replying to ARP requests with different virtual MACs, the hosts in that subnet will in effect balance the traffic across the routers, rather than send all traffic to the one active router. You can check ARP table of host and see the mac address of default gateway. But this is not an easy way.
