LLDP is enabled by default when an Aggregator auto-configures. The following message is displayed when you enable iSCSI on a switch and describes the configuration changes that are automatically performed: %STKUNIT0-M:CP %IFMGR-5-IFM_ISCSI_ENABLE: iSCSI has been enabled causing flow control to be enabled on all interfaces. EQL detection and enabling iscsi profile-compellent on an interface may cause some automatic configurations to occur like jumbo frames on all ports and no storm control and spanning tree port-fast on the port of detection. Default iSCSI Optimization Values Table 11-1 shows the default values for the iSCSI optimization feature. Table 11-1. iSCSI Optimization: Default Parameters Parameter Default Value iSCSI Optimization global setting Enabled iSCSI CoS mode (802.1p priority queue mapping) Enabled: dot1p priority 4 without remark setting iSCSI CoS Packet classification iSCSI packets are classified by VLAN instead of by DSCP values. VLAN priority tag iSCSI flows are assigned by default to dot1p priority 4 without remark setting. DSCP None: user-configurable. Remark Not configured. iSCSI session aging time 10 minutes iSCSI optimization target ports iSCSI well-known ports 3260 and 860 are configured as default (with no IP address or name) but can be removed as any other configured target.
Displaying iSCSI Optimization Information Use the show commands in Table 11-2 to display information on iSCSI optimization. Table 11-2. Displaying iSCSI Optimization Information Command Output show iscsi (Figure 11-2) Displays the currently configured iSCSI settings. show iscsi sessions (Figure 11-3) Displays information on active iSCSI sessions on the switch. show iscsi sessions detailed [session isid] Displays detailed information on active iSCSI sessions on the switch. To (Figure 11-4) display detailed information on specified iSCSi session, enter the session’s iSCSi ID. show run iscsi Displays all globally-configured non-default iSCSI settings in the current FTOS session.
