san-ext-tuner enable Chapter 21 S Commands Send documentation comments to [email protected] san-ext-tuner enable To enable the IP Network Simulator to simulate a variety of data network conditions, use the san-ext-tuner enable command. san-ext-tuner enable Syntax Description This command has no arguments or keywords. Command Default None. Command Modes Configuration mode. Command History Release 3.1(1) Modification This command was introduced. Usage Guidelines The IP Network Simulator tool is used for network simulation and is supported on the 8-port IP Storage Services (IPS-8) module and 4-port IP Storage Services (IPS-4) module only. You must also have either the SAN extension over IP package for IPS-8 modules (SAN_EXTN_OVER_IP) or SAN extension over IP package for IPS-4 modules (SAN_EXTN_OVER_IP_IPS4), so that you can enable the SAN Extension Tuner, a prerequisite for enabling and using the network simulator. You must have a pair of Gigabit Ethernet ports dedicated for each Ethernet path requiring simulation; these ports cannot provide FCIP or iSCSI functionality while simulation occurs. The remaining ports that are not performing network simulations can run FCIP or iSCSI. Ports dedicated to network simulation must be adjacent, and always begin with an odd-numbered port. For example, GE 1/1 and GE 1/2 would be a valid pair, while GE 2/2 and GE 2/3 would not. Note This command is not supported on the Cisco MDS 9124 switch, the Cisco Fabric Switch for HP c-Class BladeSystem, and the Cisco Fabric Switch for IBM BladeCenter. Examples The following example shows how to enable the SAN Extension Tuner and enable a pair of ports for network simulation. switch# config t switch(config)# switch(config)# san-ext-tuner enable switch(config)# exit switch# switch# ips netsim enable interface gigabitethernet 2/3 gigabitethernet 2/4 21-2 Cisco MDS 9000 Family Command Reference OL-18089-01, Cisco MDS NX-OS Release 4.x
