Configure ETS policies
OS10(config)#
qos-map traffic-class <queue-map-name>
OS10(config-qos-map)#
queue 0 qos-group 0-3,5-7
OS10(config-qos-map)#
queue 4 qos-group 4
OS10(config-qos-map)#
exit
OS10(config)#
OS10(config)#

OS10(config-cmap-queuing)#
match queue 0
OS10(config-cmap-queuing)#
exit

Create ETS policy-map for bandwidth allocations
OS10(config)#
policy-map type queuing <queuing-policy-name>
OS10(config-pmap-queuing)#
class LAN
OS10(config-pmap-c-que)#
bandwidth percent <bandwidth-percentage>
OS10(config-pmap-c-que)#
class iSCSI
OS10(config-pmap-c-que)#
bandwidth percent <bandwidth-percentage>
OS10(config-pmap-c-que)#
exit
OS10(config-pmap-queuing)#
exit
OS10(config)#
Note:
The sum of the bandwidth percentages must equal 100. Monitor the LAN and SAN performance in your
environment to determine optimal bandwidth settings.
