Cisco device tracking
Ip device tracking | cisco switch (urdu/hindi)
Hello there, everybody. I’m trying to allow IP device tracking on two Catalyst 6504s in a VSS setup at work (running 15.1(2)SY7). The reason for allowing it is that we are working slowly to incorporate dot1x in our organization. Activating IP user monitoring on our access switche went without a hitch. This function, according to my understanding, should be available by design, but it is not on our equipment. Here are some of the stuff I’ve tried: IP device monitoring is available globally. Didn’t do anything I tried navigating through the interfaces. The order, like trunk and entry, does not exist here. I tried disabling and then re-enabling the global command. Anything I tried resulted in the command “display ip device tracking everything” being sent, but the status remained disabled. Have any of you had a similar experience, but not necessarily on the same platform?

Setting up ip device tracking in ios
You’ll learn how to use the command line to track down devices around your network in this chapter. To be specific, I’m not referring to determining a device’s general geographic position. I’m referring to tracing a device’s connection to a particular switch or router and port. Although this isn’t something you’ll have to do very often, knowing how to locate the elusive printer or virus-infected PC will make you a hero if the situation occurs.
Many companies use WhatsUp Gold, a network management application, to keep track of network bandwidth consumption and uptime. When the network starts to slow down, the manager can turn to the network administrator (you) to decide who the top talkers are—the devices that have traditionally used the most bandwidth. Knowing these top talkers’ IP addresses is usually enough to find out where they are, particularly if they’re servers in a data center where things don’t move around much. However, you can come across a mysterious system that no one knows where or what it is!

Unfortunately, this blog has passed away (don’t worry, it was peaceful), but just like Jesus, we have a resurrection, so check out https://theworldsgonemad.net/2017/cisco-ip-device-tracking/ for a peek into the future.
Have you ever wondered how ACS obtains an end user’s IP or why the IP of the host is shown when an interface’s authentication sessions are shown? All of this is due to IP Device Tracking. I only discovered it recently when troubleshooting a problem with windows machines not receiving DHCP addresses due to collision detection due to the 0.0.0.0 address. I couldn’t find any detail on the exact reason why this happened, despite the fact that there are a lot of stories about people having similar issues and the workarounds. As a result, I figured I’d share what I learned.
IPDT maintains a database of MAC/IP per VLAN off each switchport using ARP inspection. Features that rely on it, such as 802.1x, MAB (ACS & ISE), Device sensor, Netflow, Trustsec, and web-auth, use this information. For eg, with MAB, the port is first authenticated, and then the device tracking information (IP of the device) is passed onto ACS in a subsequent RADIUS update packet.
Object tracking and ip sla
After a restart/reset, Rockwell Automation EtherNet/IP modules connected to a subnet with Cisco switches with “IP device tracking” (IPDT) enabled can go into a duplicate IP address state.
This behavior shift also eliminates the ability to disable IPDT without first disabling any IPDT-dependent features. Unless a permanent solution is in place, the Stratix line of switches will not have “IP system tracking” allowed by default.
To ensure that the device being probed is still connected and responsive, the IPDT function sends probe ARP packets with a source IP address of 0.0.0.0, the switch’s source MAC ID, and the target IP and MAC ID for the device being probed.
Probe ARP packets can be received by a Logix Ethernet module when it is in its Address Conflict Detection mechanism when a system is disconnected and then reconnected during the configurable IPDT timeout span. The EtherNet/IP module will go into a duplicate IP state and stop communicating if this occurs.
