Example 45-4 Displays DMA-Bridge Statistics
switch# show ips stats dma-bridge interface gigabitethernet 7/1
Dma-bridge ASIC Statistics for port GigabitEthernet7/1
This output shows all Fibre Channel frames that ingress or egress from the Gigabit Ethernet port.
Displaying TCP Statistics
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 45-5
