IP Device Tracking

TID_Orion — Fri, 01 Mar 2019 12:27:38 GMT

I have configured APIC-EM in stand alone mode and have discovered a majority of my network devices. On many of these devices, I am unable to view host information within the APIC console. Port information is gathered successfully. I have verified that IP device tracking is working and a "show ip device tracking all" lists all of my connected hosts on the switch. Any reason why APIC will not pick this up? Many thanks in advance!

Can you please collect RCA log ? What version are you using ?

Thank you for your response, I have uploaded the RCA log here: Dropbox - grapevine-root-172.17.20.41-rca-2016-04-08_19-12-42_UTC+0000.tar.gz

I am running version 1.1.1.34

Thanks for the log

A few more info may help:

1. How is the host connected to switch? Is it directly connected to switch or connected behind IP phone ?

2. Can you please provide specific host ip & Mac address which is missing. It would be difficult without knowing this info.

1. How is the host connected to switch? Is it directly connected to switch or connected behind IP phone ?

Most hosts are behind an IP phone, but some are not. The APIC is not detecting both types on many catalyst 3850 switches.

2. Can you please provide specific host ip & Mac address which is missing. It would be difficult without knowing this info.

An example IP and MAC: 192.168.38.20 00c0.b79f.966e
This IP and MAC show up when i run show ip device tracking all

Thanks

There was a defect - "inventory fails to add host connected to ip-phone to DB" which is what you are seeing but is supposed to fixed in version 1.1.1.34.

Can you please collect the following from 3850 switch for further debugging ?

“show ip device tracking all”

“show ip arp”

“show mac address-table”

The output from:

“show ip device tracking all”

“show ip arp”

“show mac address-table”

Can be found here: Dropbox - 3850 Output.txt

Thanks

Thanks you so much for helping us debugging this issue. This issue is supposed fixed in this release but for some reason you still have it.

Per developer's request I wonder if you can help us to collect the following, It would be really really helpful.

Show ip device tracking all

Show cdp neighbours

Show cdp neighbours detail

Show lldp neigbours

Show lldp neighbours detail

Show ip arp

Show mac address table

Show running config from that device.

Hi Manuel,

Thanks again for your help. We asked developer look into the issue the looks like they found something but need more your help.

Message from dev:

I have seen one exception in inventory.log that i fixed and check in but that is not related to 'ip device traking all' issue. So can you provide me two log file inventory.log and xde.log in debug mode.

Steps to enable debug mode:

From cluster, Goto apic-em-inventory-manager-service

$ grape instance status | grep apic-em-inventory-manager-service

apic-em-inventory-manager-service 1.2.0.804 running 57048f33-d792-4249-8af6-08cf9c85b154 169.254.0.97

(grapevine)

[Thu Apr 21 06:47:40 UTC] grapevine@172.24.100.235 (grapevine-root-1) ~

$ ssh 169.254.0.97

After enter into service:

$ su root

Password:

# cd /opt/CSCOlumos/bin/

bin# ./setLogLevel.sh ALL DEBUG

After enabling Debug clear all logs

bin# cd cd ../logs

logs# >inventory.log

logs# >xde.log

logs# rm inventory.log.*

logs# rm xde.log.*

Then do forced sync on device.

Please send me above cleared log file

for example inventory.log and xde.log

and other also like inventory.log.1,xde.log.1 etc

Thank you for your response. I have generated the logs, but have not found a way to export them out. Do you have any recommendations?

Re: IP Device Tracking

yawming — Tue, 26 Apr 2016 23:45:51 GMT

Can you do the same share on dropbox or box ?

Hi Manuel,

Here is the feedback from developer:

-------------------------------------------------------------------------------

I have seen the IPDT and cdp output.

Come to conclusion that IPDT Host is matching with CDP IP Address and this CDP Ip should not treat as Host because CDP Platform contains 'AIR' text. That's why from IPDT this Host(192.168.38.150) is removing.

if any other host is not populating as host except this. please let me know.

Re: IP Device Tracking

TID_Orion — Wed, 27 Apr 2016 16:02:11 GMT

Thank you for your response. My issue is not with these CDP clients, but with computers connected to the switch. On the switch, IP device tracking lists all of the hosts, but the APIC does not.

Some additional info:

Most hosts exist behind a ShoreTel phone

The ShoreTel phones speak LLDP

I hope that this helps. Thanks!

Re: IP Device Tracking

yawming — Wed, 27 Apr 2016 16:15:45 GMT

Do you know IPs for those computers ?

Re: IP Device Tracking

TID_Orion — Wed, 27 Apr 2016 16:40:53 GMT

Yes, the switch that I provided device tracking details earlier does not display any connected hosts on APIC. You can choose any IP from that list but the range 192.168.38.100 - 192.168.38.120 specifically includes computer hosts. Some sample active IP addresses include:

192.168.38.110

192.168.38.111

192.168.38.112

Thank you!

Re: IP Device Tracking

yawming — Fri, 29 Apr 2016 18:22:33 GMT

So looks like this is an issue in this release but will be addressed in 1.2.

Re: IP Device Tracking

TID_Orion — Mon, 02 May 2016 15:21:00 GMT

Ok. I will wait for that release. Thank you for all of your help!
