Each of the commands is described in detail in the following text. The
commands are presented in alphabetical order.
BF - List Buffer
Format: bf <loc|all> [count]]
The BF command is used to display the contents of the specified buffer
(or buffers) at location of address “loc”. If the optional [count] parameter
is used, ZSCAN will follow the buffer chain down the list until either
[count] buffers have been displayed, or an error is encountered (usually
an end of buffer chain). If [count] is not used, then only the first buffer is
displayed.
The buffer address is usually found from information displayed by other
commands such as QH (Queue header), IT (Interface table), etc.
If keyword “all” is specified as location, ZSCAN displays sequentially all
the buffer segments in the buffer pool. ZSCAN also performs basic
validation of each buffer segments. In this case, “count” is not used.
Examples:
zscan> bf 0x007FA008 2
Address: 0x007FA008 168 bytes (In use) Next: 0x007FA0B0
Data: 0x007FA02A 130 bytes Resp: 0x00000000
