Cisco IOS IP Configuration Guide
To remove IP accounting based on the MAC address from the interface, use the no ip accounting
mac-address command.
Use the EXEC command show interface mac to display MAC accounting information for interfaces
configured for MAC accounting.
Configuring IP Precedence Accounting
The precedence accounting feature provides accounting information for IP traffic based on the
precedence on any interface. This feature calculates the total packet and byte counts for an interface that
receives or sends IP packets and sorts the results based on IP precedence. This feature is supported on
all interfaces and subinterfaces and supports CEF, dCEF, flow, and optimum switching.
To configure the interface for IP accounting based on IP precedence, perform the following steps
beginning in global configuration model:
To remove IP accounting based on IP precedence from the interface, use the no ip accounting
precedence command.
Use the EXEC command show interface precedence to display precedence accounting information for
interfaces configured for precedence accounting.
Configuring TCP Performance Parameters
To tune IP performance, perform any of the optional tasks described in the following sections. To
configure various switching options, refer to the “Cisco IOS Switching Paths” chapter in the Cisco IOS
Switching Services Configuration Guide.
• Compressing TCP Packet Headers (Optional)
• Setting the TCP Connection Attempt Time (Optional)
• Enabling TCP Path MTU Discovery (Optional)
• Enabling TCP Selective Acknowledgment (Optional)
• Enabling TCP Time Stamp (Optional)
• Setting the TCP Maximum Read Size (Optional)
• Setting the TCP Window Size (Optional)
• Setting the TCP Outgoing Queue Size (Optional)
Command Purpose
Step 1
Router(config)# interface type number
Specifies the interface (or subinterface) and enters interface
configuration mode.
Step 2
Router(config-if)# ip accounting precedence
{input | output}
Configures IP accounting based on the precedence of
received (input) or transmitted (output) packets
