Description Example statistic
allocs Total number of packet allocations from the packet buffer pool by the TCP/IP protocol stack.
frees Total number of times the packet buffers are freed (released) to the packet buffer pool by the
TCP/IP protocol stack.
mediums Total number of packet allocations with size between 128 to 1536 bytes from the packet
buffer pool by the TCP/IP protocol stack.
mediums hi-watermark The highest number of packet allocation with size between 128 to 1536 bytes from the packet
buffer pool by the TCP/IP protocol stack.
jumbos Total number of packet allocations with more than 1536 bytes from the packet buffer pool by
the TCP/IP protocol stack.
jumbos hi-watermark The highest number of packet allocation with more than 1536 bytes from the packet buffer
pool by the TCP/IP protocol stack.
smalls Total number of packet allocations with size less than 128 bytes from the packet buffer pool
by the TCP/IP protocol stack.
smalls hi-watermark The highest number of packet allocation with size less than 128 bytes from the packet buffer
pool by the TCP/IP protocol stack.
failures Total number of packet allocation failures from the packet buffer pool by the TCP/IP protocol
stack.
