ErrorDisabled status on a Cisco Nexus 5020 NX-OS 5.0(2)N2(1)

Any ideas how to NOT USE errdisable or allow the FCoE switch to put a port / interface / VFC into an error disabled state?
I do not see any command(s) to NOT use this feature.
thanks
matt

You can disable errordisable condition only for certain causes. Here are the options.
F340.24.10-5548-1(config)# no errdisable detect cause ?
all           Enable error detection on all cases
inline-power Enable error disable detection for POE
link-flap     Enable error disable detection on linkstate-flapping
loopback      Enable error disable detection on loopback
But you can enable recovery if needed
F340.24.10-5548-1(config)# errdisable recovery cause ?
all                Enable timer to recover from all causes
bpduguard          Enable timer to recover from BPDU Guard error disable state
failed-port-state Enable timer to recover from stp set port state failure
inline-power       Enable timer to recover from POE disabled state
link-flap          Enable timer to recover from linkstate flapping
pause-rate-limit   Enable timer to recover from pause rate limit error disabled state
udld               Enable timer to recover from udld error disabled state
F340.24.10-5548-1(config)#
Any particular condition you are after?

Highest supported Brocade DCX firmware version to be interoperable with Cisco Nexus 5020

A Cisco Nexus 5020 (FCoE) switch is connected to Brocade DCX-B switch.
5020 is at latest firmware level of 5.0.2.N2.1
Brocade is at firmware level of 6.2.1b
If we need to upgrade brocade firmware, what is the maximum revision we can go to? Is there some documentation available for interoperability between the code levels of the two hardwares?

Hi Anwarul,
Please refer to "Table 7-10 Nexus InterOp Matrix" near the end of this link:

CISCO NEXUS 5020 Not Booting

I have a cisco nexus 5020 switch of 2 nos, but when i try to boot the device its result no image on the flash and it stuck in the boot mode. Is any possibility to boot the nexus from boot mode without having a image from flash.

Hi Michael,
If the unit is not showing anything at all when connecting screen/keyboards, there won't be much more investigation possible. Likely the HW has gone bad and you will have to replace it.

Hi All,
I have cisco 5020 nexus switch which is currently running with

I want to upgrade for

FCoE with Cisco Nexus 5548 switches and VMware ESXi 4.1

Can someone share with me what needs to be setup on the Cisco Nexus side to work with VMware in the following scenario?
Two servers with two cards dual port FCoE cards with two ports connected to two Nexus 5548 switches that are clusterd together. We want to team the ports together on the VMware side using IP Hash so what should be done on the cisco side for this to work?
Thanks...

Andres,
The Cisco Road Map for the 5010 and 5020 doesn't include extending the current total (12) FEX capabities. The 5548 and 5596 will support more (16) per 55xxk, and with the 7K will support upto 32 FEX's.
Documentation has been spotty on this subject, because the term 5k indicates that all 5000 series switches will support extended FEX's which is not the case only the 55xx will support more than 12 FEX. Maybe in the future the terminology for the 5k series should be term 5000 series and 5500 series Nexus, there are several differences and advancements between the two series.

Just to further clarify, we have 4 5548UP switches in the same management vlan. 2 switches are in one location lets say location A and they are CFS peers and are working fine.
These two switches which are having problem are in location B. All the switches are in the same vlan. Essentially the all CFS multicast messages will be seen by all 5548 switches as they are in the same vlan. I am assuming that this might not create any problems as we specify the peers in the respective configurations. Or do we have to change the CFSoIPv4 multicast addresses in location B or may be configure a different region.
Regards.

Nexus 5020/2248: Best Practice for DSCP-trust, verses DSCP-don't trust

We have several Nexus 5020/2248's for our server access to the network (approximately 1000 ports). On about 20 of these ports we want to trust the DSCP markings, since they are from out Cisco Unified Comm appliances (these are access ports). However, on all other ports (mostly access, so DSCP, but ~ 100 trunks so some are COS also) we want to "not trust" or essentially zero out any non-zero DSCP value.
Does anyone have suggestions on easiest/best method for setting the trust boundaries for Nexus 5020/2248s?
Note: vers 5.0(3) NS(1)
Thanks!
Mike.

Hi
Before any other think I would like you to upgrade your WLC image to 7.6.130.0 & FUS to 1.9.0.0. FUS upgrade will require 30-40min downtime to your wireless.
http://www.cisco.com/c/en/us/td/docs/wireless/controller/release/notes/fus_rn_OL-31390-01.html
http://www.cisco.com/c/en/us/td/docs/wireless/controller/release/notes/crn76mr03.html
It tells me to disable 802.11a and 802.11b. If I go into each radio on 'Network' tab and disable these - NOTHING can connect to any SSID. So unless I've misunderstood something - this is a contradiction in the best-practice link I posted above,
This simply says, you have to disable radio band before changing QoS profile values. Once you change those value you can re-enable the radio band. :)
If I enable FT-PSK and PSK - for devices that support FT-PSK (which i'm under the impression is 802.11r) will these devices use that and for devices that don't they'll use 'regular' PSK? How do I know if my client is connecting using PSK or FT-PSK as both are enabled on the same WLAN.
Read these 802.11r post & you will understand how 802.11r works. There are certain client devices does not like PSK & FT-PSK capability advertise on the same SSID & may have connectivity issues. But most of the clients like iPhone, iPads,etc will connect without any problems.

http://mrncciew.com/2014/09/08/cwsp-802-11r-over-the-ds-ft/
"show client detail <mac_address>" should indicate if client connected over FT-PSK or PSK.

DCNM 6.1.1a and Nexus 5020

Hi all,
I've got a problem that I am not able to figure out.
I've got 2 nexus 5020 running
Software
system:    version 5.0(2)N2(1)
system image file is:    bootflash:/n5000-uk9.5.0.2.N2.1.bin
Hardware
cisco Nexus5020 Chassis ("40x10GE/Supervisor")
I use Nagios for management and so far, everything is working fine. Since a couple of days, I was thinking to install dcnm 6.1.1a on a red hat linux to test the app and see what can I do with the nexus. The problem is that every time that I try to work with the DCNM app, the CPU goes up a lot.
The show process cpu history is the following:

Could SNMP be the cause of this high CPU? How could I confirm it? Maybe it is a bug but I could not find anything.
Any ideas or comments are welcomed!
THanks in advance,
Fernando

Just to close this thread, we saw that the average cpu utilization is 10%. The CPU spikes might be due to the polling time or some cosmetic output. There is no output error, no discards, no traffic loss.

After trying to build a port-channel with a 1G port on slot 1 and a 1G port on slot 10 i get a messague with incompatible port.
Can any one tell me if its supported a port-channel with ports on the following modules :
N7K-M148GS-11L
N7K-F248XP-25E
Thanks
Patrício

Hi Particio,
The port-channel/vPC features require that all uplinks are connected to the same type of
module. You can refer to the following document.

Cisco Nexus 3K Layer 3 Connectivity Issue while using Optical SFP

Dear All,
Am facing L3 reachability issue between N3k switched, even in same subnet. Also checked that VLAN is allowed under trunk port.
I can able to see the switch details as CDP neighbour.
We are using SVI, and found all the SVI and Interface protocol status is up/up. So to test I use a host to directly connect N3k with Optical SFP in access port, found failure on reachability, but while replacing with SFP ethernet module instead of SFP optical module reachability is okay.
Please help me to resolve this issue.
Thanks,
Kannan,

Cisco Nexus 5010 FCOE Interconnection

Hi, i would really apreciate your help on this doubt.
Is it possible to create a link between two cisco nexus 5010
using CNA interfaces ?
I've already configured the ethernet interfaces(where the cna is plugged in),
i've binded the E1/2, mapped the vsan, created specific traffic vlan, and so on ...
I have tried everything what's written in the manual but the vcf interface won't set up, keeps telling me "vcf is down" .
What am i doing wrong ? or this connection is imposible ...
Thanks in advance.

Routing issue between Cisco Nexus and Cisco 4510 R+E Chassis

We have configured Cisco Nexus 7K9 as core and Cisco 4510 R+E as access switches for Server connectivity.
We are experiencing problem in terms of ARP learning and Ping issues between Cisco Nexus and end hosts.

Hi,
So you have N7k acting as L3 with servers connected to 4510?.
Do you see the MAC associated with failing ARP in 4510?. Is it happening with all or few servers?. Just to verify if it is connectivity issue between N7k and 4510, you can configure an SVI on 4510 and assign address from same raneg (server/core range) and perform a ping.
This will help narrow down if issue is between server to 4510 or 4510 to N7k.
Thanks,
Nagendra

How to change default FCoE QoS class - Nexus 5020

I see that on a Nexus 5020, the default FCoE QoS class is 50%. I am not using FCoE so I would like to adjust this value to 0%. I switch complains and says I can't change default values. How should I go about getting around this to eliminate the FCoE queue and give 100% BW to default? Thanks.

No. The default classloader is a builtin classloader in
the JRE. You can use other classloaders.
The java.net.URLClassLoader is provided in
the JDK. That's the only one. Otherwise you
should subclass ClassLoader and implement
the loadClass method (f.i.
loadClass("my.program") {
String file="my.program".replace('.','/') + ".class";
// find the file in classpath
// read the class file in a byte[]
return defineClass(byte[]);
although this is not the advised way to do it. Search the web for how to implement a classloader directly.
