Reference Guide

The information learnt about iSCSI sessions on VLT LAGs are synchronized with the VLT peers.
The synchronization of the iSCSI sessions happens based on various scenarios:
● If the iSCSI login request is received on an interface that belongs to a VLT LAG, the information is synchronized with the
VLT peer and the connection is associated with the interface.
● Any additional updates to connections, including aging updates, that are learnt on VLT LAG members are synchronized with
the VLT peer.
● If the iSCSI login request is received on a non-VLT interface, followed by a response from a VLT interface, then the
connection is associated with the VLT LAG interface and the information about the session is synchronized with the VLT
peer.
● When VLT interconnect comes up, information about iSCSI sessions learnt on VLT LAG is exchanged 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 (5 to 43,200).
Default 10 minutes
Command Mode CONFIGURATION
Usage
Information
Configure the aging time 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 auto-detection of attached storage arrays and switch auto-configuration.
Syntax
iscsi enable
Parameter None
Default Enabled on S4048T-ON/S4048-ON; disabled on others
Command Mode CONFIGURATION
Usage
Information
iSCSI optimization automatically detects storage arrays and auto-configures switch ports with the iSCSI
parameters received from a connected device. The no version of this command disables iSCSI auto-
detection.
Example
OS10(config)# iscsi enable
Supported
Releases
10.3.0E or later
iscsi priority-bits
Resets the priority bitmap advertised in iSCSI application TLVs.
Syntax
iscsi priority-bits {priority-bitmap}
