Table 140: show system buffers Output Fields
Field Description
Field Name
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.
mbufs in use
Number of memory buffers currently holding packet headers
mbufs allocated to
packet headers
Number of memory buffers currently holding state for sockets.
mbufs allocated to
control blocks
Number of memory buffers currently holding socket send data.
mbufs allocated to
send data
Number of memory buffers currently holding Packet Forwarding Engine refill data.
mbufs allocated to pfe
refill data
Number of memory buffers currently holding fxp data.
mbufs allocated to fxp
data
Number of memory buffers currently holding addresses for sockets.
mbufs allocated to
socket names and
addresses
Allocation statistics for mbuf clusters.
mbuf clusters in use
Total amount of memory in use by the networking and interprocess communication (IPC) code.
allocated to network
Number of times a memory allocation request within the IPC and networking code failed.
requests for memory
denied
Number of times a memory allocation request within the IPC and networking code was postponed.
requests for memory
delayed
Number of times a memory allocation request within the IPC and networking code triggered a memory
reclamation attempt.
