Configuring Gigabit Ethernet Interfaces
S e n d d o c u m e n t a t i o n c o m m e n t s t o m d s f e e d b a c k - d o c @ c i s c o . c o m .
Use the physical interface, not the subinterface, to display TCP/IP statistics.
Note
Example 37-10 Displays IP Statistics
switch# show ips stats ip interface gigabitethernet 4/1
Internet Protocol Statistics for port GigabitEthernet4/1
Use the show ips stats tcp interface gigabitethernet to display and verify TCP statistics. This
command takes the main Ethernet interface as a parameter, and shows TCP stats along with the
connection list and TCP state. The detail option shows all information maintained by the interface. See
Example 37-11
