Modification

3.1(1)

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

Added engineID options.

1.0(2)

This command was introduced.

1.0(3)

Added the localizedkey option.

2.0(1b)

Added the auto and aes128 options.


Usage Guidelines

The localized keys are not portable across devices as they contain information on the engine ID of the device. If a configuration file is copied into the device, the passwords may not be set correctly if the configuration file was generated at a different device. We recommend that passwords be explicitly configured to the desired passwords after copying the configuration into the device.

SNMP Version 3 is the most secure model, as it allows packet encryption with the priv keyword.

To assign multiple roles to a user, perform multiple snmp-server user username group-name commands. The group-name argument is defined by the role name command.

Examples

The following example sets the user authentication and SNMP engine ID for a notification target user:

switch# config terminal
switch(config)# snmp-server user notifUser network-admin auth sha abcd1234 engineID 
00:12:00:00:09:03:00:05:48:00:74:30

The following example sets the user information:

switch# config terminal
switch(config)# snmp-server user joe network-admin auth sha abcd1234 engineID 
switch(config)# snmp-server user sam network-admin auth md5 abcdefgh
switch(config)# snmp-server user Bill network-admin auth sha abcd1234 priv abcdefgh

Starting with NX-OS 4.1(1b), DMM must be enabled using the ssm enable feature dmm command before using the SLD tool.


Caution The force option is only applicable when unprovisioning (using the no parameter). Using the force parameter without the no keyword causes the SSM to reload.

For SAN-OS Release 2.1 and later NX-OS Release 4.1 images, intelligent services can be configured on a range of interfaces with the following restrictions:

The minimum range is four interfaces.

The range of interfaces must be specified in multiples of four interfaces. For example, 4, 8, 12, 16, 20, 24, 28, 32.

static (iSCSI initiator configuration and iSLB initiator configuration)

To assign persistent WWNs to an iSCSI initiator or iSLB initiator, use the static command in iSCSI initiator configuration submode or iSLB initiator configuration submode. To disable this feature, use the no form of the command.

static {nwwn | pwwn} {wwn-id | system-assign}

no static {nwwn | pwwn} {wwn-id | system-assign}

Syntax Description

nwwn

Configures the initiator node WWN hex value.

pwwn

Configures the peer WWN for special frames.

wwn-id

Specifies the pWWN or nWWN ID.

system-assign

Generates the pWWN or nWWN value automatically.


Defaults

None.

Command Modes

iSCSI initiator configuration submode.

iSLB initiator configuration submode.

Command History

Release
Modification

1.3(2)

This command was introduced.

3.0(1)

Added iSLB initiator configuration submode.


Usage Guidelines

We recommend using the system-assign option. If you manually assign a WWN, you must ensure its uniqueness. You should not use any previously-assigned WWN.

If you use system-assign option to configure WWNs for an iSLB initiator, when the configuration is saved to an ASCII file, the system-assigned WWNs are also saved. If you subsequently perform a write erase, you must manually delete the WWN configuration from the ASCII file. Failing to do so can cause duplicate WWN assignments if the ASCII configuration file is reapplied on the switch.

Examples

The following example uses the switch WWN pool to allocate the nWWN for this iSCSI initiator and to keep it persistent:

switch# config terminal 
Enter configuration commands, one per line.  End with CNTL/Z.
switch(config)# iscsi initiator name iqn.1987-02.com.cisco.initiator
switch(config-iscsi-init)# static nWWN system-assign

The following example uses the switch WWN pool to allocate two pWWNs for this iSCSI initiator and to keep it persistent:

switch(config-iscsi-init)# static pWWN system-assign 2

The following example shows a system-assigned pWWN for an iSLB initiator:

switch# config t
switch(config)# islb initiator ip-address 209.165.200.226

switch(config-islb-init)# static pwwn system-assign 4

The following example removes the system-assigned pWWN for the iSLB initiator:

switch (config-islb-init)# no static pwwn system-assign 4

Usage Guidelines

You can specify a range of interfaces by issuing a command with the following example format:

interfacespacefc1/1space-space5space,spacefc2/5space-space7


Tip The shutdown or no shutdown command for the FCIP or iSCSI interfaces is automatically issued when you change the MTU size—you do not need to explicitly issue this command.


You must perform the fcrxbbcredit extended enable command in configuration mode to use the switchport fcrxbbcredit extended command in interface configuration submode to enable extended BB_credits on a Fibre Channel interface.

The port speed on an interface, combined with the rate mode, determines the amount of shared resources available to the ports in the port group. Especially in the case of dedicated rate mode, the port group resources are reserved even though the bandwidth is not used. For example, if an interface is configured for autosensing (auto), then 4 Gbps of bandwidth is reserved even though the maximum operating speed is 2 Gbps. For the same interface, if autosensing with a maximum speed of 2 Gbps (auto max 2000) is configured, then only 2 Gbps of bandwidth is reserved and the unused 2 Gbps is shared with the other interface in the port group.


Note The 4-port 10-Gbps switching module only supports 10-Gbps traffic.

When configuring port modes, observe the following guidelines:

Auto port mode and E port mode cannot be configured in shared rate mode.

The 4-port 10-Gbps module does not support FL port mode.

Generation 2 modules do not support TL port mode.

Shared to dedicated ports should be configured in this order: speed, rate mode, port mode, credit.

Dedicated to shared ports should be configured in this order: credit, port mode, rate mode, speed.

When configuring PortChannels, observe the following guidelines:

When an interface is out-of-service, it cannot be part of a PortChannel.

The 24-port module and the 48-port module support making ports out-of-service. In a shared resource configuration, an out-of-service port reverts to its default values when it comes back into service.

The maximum number of PortChannels for Generation-2 modules is 256.

The maximum number of PortChannels for a mixture of Generation-1 and Generation-2 modules is 128.

The number of PortChannels is independent of the type of supervisor module.

When adding a PortChannel to a configuration that uses both Generation-1 and Generation-2 modules, configure the PortChannel and Generation-2 interface speed to auto max 2000.

When using the force option to add a PortChannel to a configuration that uses both Generation-1 and Generation-2 modules, follow these guidelines:

Configure the PortChannel interface speed to auto max 2000, or add the Generation-1 interfaces followed by the Generation-2 interfaces.

Generation-1 interfaces do not support the auto max 2000 speed.

The force addition can fail for a Generation-2 interface if resources are unavailable.

Examples

The following example shows how to configure NP port mode:

switch# config t
Enter configuration commands, one per line.  End with CNTL/Z.

Syntax Description

This command has no arguments or keywords.

Defaults

None.

Command Modes

Interface configuration submode.

Command History

Release
Modification

2.1(1a)

This command was introduced.


Usage Guidelines

The bit error rate threshold is used by the switch to detect an increased error rate before performance degradation seriously affects traffic.

Bit errors can occur for the following reasons:

Faulty or bad cable

Faulty or bad GBIC or SFP

GBIC or SFP is specified to operate at 1 Gbps but is used at 2 Gbps

Short haul cable is used for long haul or long haul cable is used for short haul

Momentary sync loss

Loose cable connection at one or both ends

Improper GBIC or SFP connection at one or both ends

A bit error rate threshold is detected when 15 error bursts occur in a 5-minute period. By default, the switch disables the interface when the threshold is reached. You can issue a shutdown/no shutdown command sequence to reenable the interface.


Note Regardless of the setting of the switchport ignore bit-errors command, the switch generates a syslog message when bit error threshold events are detected.


Examples

The following example shows how to prevent the detection of bit error events from disabling the interface:

switch# config t
switch(config)# interface fc1/1
switch(config-if)# switchport ignore bit-errors

The following example shows how to allow the detection of bit error events from disabling the interface:

switch# config t
switch(config)# interface fc1/1
switch(config-if)# no switchport ignore bit-errors
