Displaying TCP IP information
The following TCP IP information is available from the BP console within the rconsole mode:
• SSL, TCP, and IP buffer information
• TCP and IP chain length statistics
• SSL, TCP, and IP queues
• SSL memory
To access the display command that present this information, you must enter the BP console using
the rconsole command.
Displaying SSL, TCP, and IP buffer information
Use the show tcp-ip buffers command in rconsole mode to display SSL, TCP, and IP buffer
information as shown:
ServerIronADX# rconsole 1 1
ServerIronADX1/1# show tcp-ip buffer
