Fine tuning ERS buffers (leave as default or assess device distribution first):

qos agent buffer <regular | large | maximum>

With this command you can set how much of the buffer a single port can use:

Regular    1 port may use up to 16% of the buffers       for a group of 12 ports.
Large    1 port may use up to 33% of the buffers       for a group of 12 ports.
Maximum    1 port may use 100% of the buffers for a       group of 12 ports.

To take effect a change of the buffer value you have to reboot your ERS switch.
