We're doing some research around Cisco's Nexus platform. To accomplish our research, we need some data from production Nexus devices. We're specifically interested in Nexus 7K and 5Ks with attached FEX. If you have one or several of these devices you're eligible.

To do this using putty, click Session in the left index, enter your Host Name, and click the Open button. * Log in to your device and the copy/paste the commands from the attached file into your terminal. These are show commands and are not invasive. * Once complete, upload the putty.log (compressed it if needed) from the location defined in Step 2 to https://Share.SolarWinds.com/?ShareToken=1551A7184FFFD8EDEB3F77A9F2FCE3DB3947B07C * Make a comment on this thread and I'll get you your Thwack points.

cobrien serena photos don't load, but I've got two sets of 7k -> dual 5ks -> FEX (2 physical locations). I ran the CLI stuff for you and also did the SNMPWalk on each of the two 7K's. Just uploaded.

rschroeder

I've tried the snmp walk previously; it always errors out after about 40,000 lines of response. The error suggests a security limitation has been reached. Perhaps Cisco doesn't want folks to do full MIB walks?

Any suggestions for getting around this limitation?

dave_ent

I uploaded the CLI data but had the same issue with the walk. See below the error message from SNMP walk. I think some of the OIDs are not customer accessible. I got to 88600 before it crashed.

cobrien1

Fixed photos. I copy pasted the images in and it just used links to our internal wiki which actually render properly for anyone at SolarWinds, so I didn't see the problem!

Points should be arriving shortly. Thanks!

rschroeder

That's exactly what my snmp walk ran into after ~40,000 hits.

designerfx

I dare to ask, but do you guys have more than say, 20-30 fex's? Pure speculation but curious. I think we had somewhere in that realm and it didn't error out. Also: SNMPv2 (laughably/sadly).

designerfx

also realized I neglected to include same details for 5K's, so that'll be uploaded shortly. One set of 5K's complete.

jamison.jennings

SNMPv3 and crashed around 43xxx, but I saved the file and got the command line and uploaded.

cobrien1

Can you try polling these separately?

SNMPv2-MIB:system OID: 1.3.6.1.2.1.1

IF-MIB:interfaces: OID: 1.3.6.1.2.1.2

IF-MIB:ifMIB OID: 1.3.6.1.2.1.31

RFC1213-MIB:ip OID: 1.3.6.1.2.1.4

ENTITY-MIB:entityMIB OID: 1.3.6.1.2.1.47

ciscoMgmt OID: 1.3.6.1.4.1.9.9

deverts

I know you requested N7 or N5 with FEX, but I uploaded N9396 with FEX...sorry, all I got for you.

vcaldwell

I uploaded a file (5K 2000), but can't get the snmpwalk to run, it times out. I also tried polling separately with the OID's above with the same results.

rschroeder

We have just twenty-one FEXes in this ACI deployment.

Maybe the problem we're running into with OID's listed stopping at ~40,000 is we use snmp-v3.

designerfx

Seems that way

paulrobbins

Files uploaded - similar issue with the SNMPwalk (albeit after nearly 200000 lines) but it does include the OID's listed above ..

mark.healey

We've got a pair of 5548s connected to 17 FEX units.

We're running snmpv3 and I get the same error here at 96210.

I've uploaded the CLI and the SNMPWalk output.

I hope it's of use

kmillerusaf

Uploaded files... I received a couple of security errors when running the SNMPwalk so if I'm missing something, please feel free to let me know.

stevenstadel

Send a couple of 5Ks

jonchill

Just uploaded a MIB walk and Putty output from our Nexus 5672.

bobby.alvarez

Uploaded both files from our Nexus 7710.

df112

Just uploaded both files from our Nexus 5Ks. 12 FEXs.

dbucks01

just uploaded both files for 2 nexus 5k's

greg.grimes

Just uploaded 2 7ks with 8 attached FEXs. We have 5ks and 9ks but no FEXs on those.

superfly

I just uploaded the CLI file and snmpwalk for a Nexus 5K.

familyofcrowes

Uploading my 9K's and 5K's.... enjoy :-)

rscreed92

Files Uploaded 5K and 7K.

Gustelj

I've just uploaded SNMP Walk and session trace log files of our Nexus 5672 with a couple of FEXes. Looking forward to better support of Cisco Nexus devices in Solarwinds products.

atuor

Uploaded the putty.log and snmpwalk files. I had a few security errors on the SNMPWALK as experienced by other users as well.

tim.hearne

If we can get something like in the hardware section this without having to manually select all of the fields it would be good. A separate section for the 7k/9k itself and another one for the FEX. Basically the status for the different modules.

We are currently trying to get this info onto a email report but having some issues. Its kind of convoluted to put it together as it sits now.

dclick

Just dropped off 2 files for your review. I have 6 5ks (with Fex's) and 4 7010's if you need more. (we are a big cisco shop.)

tomiannelli

cobrien - Uploaded file from our single 7009. Let me know if it has everything you need.

ScottRich

I have uploaded files for N5K. Had similar time-out issues as seen in previous comments.

ecklerwr1

I have a bunch of FEX attached to my nexus. Uploading what I've got.

vinod2599

Uploaded output files from Nexus 5K with 2 Fexes

bps

uploaded output of 1Nex5k with 1FEX

RaviK

Sent the SNMP walk of Nexus 5k and Nexus 7k via email

mdhtbm

SNMP walks and the PuTTY logs have been uploaded for both 5ks (with attached FEXes) and 7ks.

dodo123

Uploaded 4 x 5K SNMP Walks and 4 x Putty Logs zipped to filename cisco.zip.

Hope there useful, Thanks

cobrien1

Thanks so much for all the uploads so far. The Dev team is devouring them.

So far it appears we have not received any uploads for a Nexus running multiple VDCs. If you have one, we'd love the upload. If you already uploaded a device that has multiple VDCs, please let me know and we will dig deeper as to why we're not detecting it. Thanks!

tomiannelli

cobrien sent you a DM. My Nexus has 4 VDCs besides the Administrative one.

mikeit83

I had 100,000+ on our 5596...
