Dynamic Buffer (Conf) The dynamic buffer allocation, as configured
Dynamic Buffer (Actual) The dynamic buffer allocation, as it is before reboot sets the
value to the configured value
Fixed Buffer (Conf) The static buffer allocation, as configured
Fixed Buffer (Actual) The static buffer allocation, as it is before reboot sets the
value to the configured value
Over-sub (Conf) Oversubscription ratio to be made available to dynamic
buffering, as configured
Over-sub (Actual) Oversubscription ratio available to dynamic buffering, as it is
before reboot revises the memory allocation to static buffers
Pkt Limit (Conf) The packet limit allocation, as configured

Version 2.5.1 Introduced
buffer check Verify that the configured buffer allocations meet the hardware requirements.
buffer dedicated (1G and
stacking ports)
Set buffer sizes per port and per queue for ports 1 – 48 and the stack port on
the S50, and ports 1 – 52 and the stack port on the S50V.
buffer dynamic (1G and stack
ports)
Set dynamic buffer sizes per port for ports 1 – 48 and the stack port on the
S50, and ports 1 – 52 and the stack port on the S50V
show buffer allocation
interface
Display configured and actual static buffer allocation and packet allocation
values per queue for the
selected port in an S50, S50V, or S25P.
