IP Device Tracking

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

have uploaded the RCA log & running version 1.1.1.34

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

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.

collect the following from 3850 switch for further debugging .

“show ip device tracking all”

“show ip arp”

“show mac address-table”

Also collect the following:

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.

Have seen one exception in inventory.log that is 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.

After checking the the IPDT and cdp output came 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.
