Connectivity Guide

Usage Information To congure the aging timeout in iSCSI monitoring sessions use the iscsi aging time command. To congure
the TCP ports that listen for connected storage devices in iSCSI monitoring sessions use the iscsi target
port
command. The no version of this command disables iSCSI session monitoring.
NOTE: When you enable iSCSI session monitoring, you can monitor a maximum of 100 connections.
Example
OS10(config)# iscsi session-monitoring enable
Supported Releases 10.3.0E or later
iscsi target port
Congures the TCP ports used to monitor iSCSI sessions with target storage devices.
Syntax
iscsi target port tcp-port1 [tcp-port2, ..., tcp-port16] [ip-address ip-
address]
Parameters
• tcp-port — Enter one or more TCP port numbers, from 0 to 65535. Separate TCP port numbers with a
comma.
• ip-address ip-address — (Optional) Enter the IP address in A.B.C.D format of a storage array whose
iSCSI trac is monitored on the TCP port.
Default 3260,860
Command Mode CONFIGURATION
Usage Information You can congure a maximum of 16 TCP ports to monitor iSCSI trac from target storage devices. The no version
of this command including the IP address removes a TCP port from iSCSI monitoring.
Example
OS10(config)# iscsi target port 26,40
Supported Releases 10.3.0E or later
lldp tlv-select dcbxp-appln iscsi
Enables a port to advertise iSCSI application TLVs to DCBX peers.
Syntax
lldp tlv-select dcbxp-appln iscsi
Parameter None
Default iSCSI application TLVs are advertised to DCBX peers.
Command Mode INTERFACE
Usage Information DCB devices use DCBX to exchange iSCSI conguration information with peers and self-congure. iSCSI
parameters exchange in time, length, and value (TLV) messages. DCBX requires LLDP enabled to advertise iSCSI
application TLVs. iSCSI application TLVs advertise the PFC dot1p priority-bitmap congured using the iscsi
priority-bits command to DCBX peers. If you do not congure an iSCSI dot1p-bitmap value, iSCSI
application TLVs advertise dot1p 4 by default only if you congure dot1p 4 as a PFC priority using the
pfc-cos
command. The no version of this command disables iSCSI TLV transmission.
Example
OS10(conf-if-eth1/1/1)# lldp tlv-select dcbxp-appln iscsi
