IP Accounting (Layer 3) collects individual IP address details, so it can be used to identify specific users for usage-based billing. Traffic generated by the router or traffic terminating in the router is not included in the accounting statistics. Only transit traffic that enters and leaves the router is measured, and only on an outbound basis. IP Accounting (Layer 3) collects the number of bytes and packets processed by the network element on a source and destination IP address basis. It concludes by comparing the IP Accounting features to the questions raised in Chapter 2, “Data Collection Methodology”: First, the fundamentals are explained, followed by an overview of CLI operations, and then SNMP operations. This chapter discusses in detail each flavor of IP Accounting, using a basic structure. Therefore, this book uses the command-line interface (CLI) commands as titles, except for “IP Accounting Access Control List,” where the related CLI command is ip accounting access-violations. Note that Cisco documentation is not always consistent for the different IP Accounting features.

IP Accounting Access Control List (ACL).Basic IP Accounting, which this book calls “IP Accounting (Layer 3)”.Refer to coverage of NetFlow Layer 2 and the Security Monitoring Exports feature in Chapter 7, “NetFlow.” Note that NetFlow recently added the export of the MAC address as a new information element. Furthermore, access-list accounting currently cannot be solved with the NetFlow implementation. However, compared to NetFlow, IP Accounting offers some advantages that make it an interesting feature to investigate: easy results retrieval via a MIB and limited resource consumption.

The fact that Cisco has considered replacing IP Accounting by adding new features to NetFlow potentially turns IP Accounting into a corner case solution. IP Accounting is a very useful accounting feature in Cisco IOS, but it’s not as well known as other features, such as NetFlow. Show ip interface brief - will give you the IP address information of ANY layer 3 interface - so this is a very helpful command to remember. I hope you must be able to find the IP address from the router as the device connected to F0/7 of switch has to comminicate over the router at some point of time. After taking down the mac address from the local switch using show mac-address-table command, log on to nearby router or 元 switch and issue the show arp to get the IP address. Once you have done that, you can do one of two things: - if the switch is a 元 switch, issue the command 'sh ip arp' to see if the MAC address is one that has been resolved recently. As you indicated, you can get the MAC address of the device by using the 'show mac-address-table' command. It's worth noting that on some Cisco devices the command 'show mac-address-table' also works. If successful it should look like the picture. Next type the command 'show mac address-table'. Next enter 'enable' mode on the switch by typing enable.

On the layer 2 device (switch) enter the username and password if needed. 7) show output of show interface status of switch where panel is connected. Is the IP assigned to the panel the address that you arp for? 6) assuming that the panel is connected to a switch can you check the mac address table of the switch and verify that the mac address of the panel does show up on the port that you believe it is connected to.
