Commands
show buffer unit
This command displays configured values for dedicated buffers, dynamic buffers, and packet limits for
each ASIC in the selected S50, S50V, or S25P, as well as the actual settings from the switch hardware.
Because configured values do not take effect until the stack is rebooted, the hardware values can be
different.

buffer dedicated (1G and
stacking ports)
Sets buffer sizes per port and per queue for the ASICs controlling ports 1 – 48
and the stack port on the S50, and ports 1 – 52 and the stack port on the S50V
buffer dedicated interface
(10G ports)
Set buffer sizes per port and per queue for ASICs controlling the optional
10Gb ports 49 and 50 on the S50 and the 10Gb ports on the S25P.
