Table 97: show system buffers Output Fields
Field Name Field Description
mbufs in use Memory buffers (mbufs) are 128-byte buffers that are used for various purposes inside the kernel.
Each memory buffer has a type, and the output itemizes the amount allocated for each type. Types
with no memory buffers allocated are not displayed.
