API Guide

● If the iSCSI session does not receive control packets but receives data packets on the VLT LAG. This happens when you
enable iSCSI session monitoring after the iSCSI session starts.
The information learned about iSCSI sessions on VLT LAGs synchronizes with the VLT peers.
iSCSI session synchronization happens based on various scenarios:
● If the iSCSI login request is received on an interface that belongs to a VLT LAG, the information synchronizes with VLT peer
and the connection associates with the interface.
● Any updates to connections, including aging updates that are learned on VLT LAG members synchronizes with the VLT peer.
● If the iSCSI login request is received on a non-VLT interface, followed by a response from a VLT interface, the connection is
associated with the VLT LAG interface and the information about the session synchronizes with the VLT peer.
● When a VLT interconnect comes up, information about iSCSI sessions learned on the VLT LAG exchanges between the VLT-
peers.
iSCSI commands
iscsi aging
Sets the aging time for monitored iSCSI sessions.
Syntax
iscsi aging [time minutes]
Parameters time minutes — Enter the aging time in minutes allowed for monitoring iSCSI sessions, from 5 to
43,200.
Default 10 minutes
Command Mode CONFIGURATION
Usage
Information
Configure the aging time that is allowed for monitored iSCSI sessions on TCP ports before the session
closes. The no version of this command disables the aging time.
Example
OS10(config)# iscsi aging time 30
Supported
Releases
10.3.0E or later
iscsi enable
Enables iSCSI autodetection of attached storage arrays and switch autoconfiguration.
Syntax
iscsi enable
Parameter None
Default
None
Command Mode CONFIGURATION
Usage
Information
iSCSI optimization automatically detects storage arrays and autoconfigures switch ports with the iSCSI
parameters that are received from a connected device. The no version of this command disables iSCSI
autodetection.
Starting from release 10.4.1.1, when you perform a fresh installation of OS10, iSCSI autoconfig is enabled
and flow control receive is set to on. However, when you upgrade from an earlier release to release
10.4.1.1 or later, the existing iSCSI configuration is retained and the flow control receive could be set to on
or off, depending on the iSCSI configuration before upgrade.
Example
OS10(config)# iscsi enable
