Configuring iSCSI Optimization 443
The following commands show how to configure the iSCSI example depicted 
in Figure 16-6.
1
Enable iSCSI optimization on the switch.
console#config
console(config)#iscsi enable
2
Configure the switch to associate the DSCP priority 45 (and the queue 
that is mapped to it) with detected iSCSI session traffic. The 
remark
 
keyword indicates that the switch should add this priority marking on 
packets as it forwards them.
console(config)#iscsi cos dscp 45 remark
console(config)#exit
3
The default target port and IP address criteria is used to determine which 
packets are snooped for iSCSI session data (ports 860 and 3260; any IP 
address), so no additional commands are required.
