P Commands


The commands in this chapter apply to the Cisco MDS 9000 Family of multilayer directors and fabric switches. All commands are shown here in alphabetical order regardless of command mode. See "About the CLI Command Modes" section on page 1-3 to determine the appropriate mode for each command.

passive-mode

To configure the required mode to initiate an IP connection, use the passive-mode command. To enable passive mode for the FCIP interface, use the no form of the command.

passive-mode

no passive-mode

Syntax Description

This command has no keywords or arguments.

Defaults

Disabled

Command Modes

Interface configuration submode.

Command History

Release
Modification

1.1(1)

This command was introduced.


Usage Guidelines

Access this command from the switch(config-if)# submode.

By default, the active mode is enabled to actively attempt an IP connection.

If you enable the passive mode, the switch does not initiate a TCP connection and only waits for the peer to connect to it.

Examples

The following example enables passive mode on an FCIP interface:

switch# config terminal
switch(config)# interface fcip 1
switch(config-if)# passive-mode

Related Commands

Command
Description

show interface fcip

Displays an interface configuration for a specified FCIP interface.


password strength-check

To enable password strength checking, use the password strength-check command. To disable this feature, use the no form of the command.

password strength-check

no password strength-check

Syntax Description

This command has no arguments or keywords.

Defaults

Enabled.

Command Modes

Configuration mode.

Command History

Release
Modification

NX-OS 4.1(1b)

This command was introduced.


Usage Guidelines

When you enable password strength checking, the NX-OS software only allows you to create strong passwords.

The characteristics for strong passwords included the following:

At least 8 characters long

Does not contain many consecutive characters (such as abcd)

Does not contain many repeating characters (such as aaabb)

Does not contain dictionary words

Does not contain proper names

Contains both uppercase and lowercase characters

Command History

Release
Modification

3.2(1)

This command was introduced.


Usage Guidelines

In a dual-fabric topology, the migration job runs on an SSM in each fabric. The two SSMs exchange messages over the management IP network, so each SSM needs the IP address of the peer.

Examples

The following example shows how to add peer SSM information to a job:

switch# config t
Enter configuration commands, one per line. End with CNTL/Z.
switch(config)# dmm module 3 job 1 create
Started New DMM Job Configuration.
Do not exit sub-mode until configuration is complete and committed
switch(config-dmm-job)# peer 224.2.1.2
switch(config-dmm-job)#

Related Commands

Command
Description

show dmm ip-peer

Displays the IP peer of a DMM port.

show dmm job

Displays job information.


peer-info ipaddr

To configure the peer information for the FCIP interface, use the peer-info ipaddr command. To remove the peer information for the FCIP interface, use the no form of the command.

peer-info ipaddr address [port number]

no peer-info ipaddr address [port number]

Syntax Description

ipaddr address

Configures the peer IP address.

port number

Configures a peer port. The range is 1 to 65535.


Defaults

None.

Command Modes

Interface configuration submode.

Command History

Release
Modification

1.1(1)

This command was introduced.


Usage Guidelines

Access this command from the switch(config-if)# submode.

The basic FCIP configuration uses the peer's IP address to configure the peer information. You can also use the peer's port number, port profile ID, or port WWN to configure the peer information. If you do not specify a port, the default 3225 port number is used to establish connection.

Examples

The following command assigns an IP address to configure the peer information. Since no port is specified, the default port number, 3225, is used:

switch# config terminal
switch(config)# interface fcip 10
switch(config-if)# peer-info ipaddr 209.165.200.226

The following command deletes the assigned peer port information:

switch(config-if)# no peer-info ipaddr 209.165.200.226

The following command assigns the IP address and sets the peer TCP port to 3000. The valid port number range is from 0 to 65535:

switch(config-if)# peer-info ipaddr 209.165.200.226 port 3000

The following command deletes the assigned peer port information:

switch(config-if)# no peer-info ipaddr 209.165.200.226 port 2000

Related Commands

Command
Description

show interface fcip

Command Modes

Call Home configuration submode.

Command History

Release
Modification

2.0(x)

This command was introduced.


Usage Guidelines

None.


Note The time of day value is not absolute. When you change the time of day of the Periodic Inventory, a notification will be generated only after 24 hours (interval of 1 day). For example, if you change the time of day to 2 minutes, a notification will be generated in 24 hours + 2 minutes.


Examples

The following example shows how to enable periodic inventory notification and use the default interval:

switch# config terminal
switch(config)# callhome
switch(config-callhome)# periodic-inventory notification

The following example shows how to enable periodic inventory notification and set the interval to 10 days:

switch# config terminal
switch(config)# callhome
switch(config-callhome)# periodic-inventory notification interval 10
switch(config-callhome)#

The following example shows how to specify the timeofday for periodic inventory in Hours Minutes format:

Command Modes

IPv6-ACL configuration submode.

Command History

Release
Modification

3.0(1)

This command was introduced.


Usage Guidelines

The following guidelines can assist you in configuring an IPv6-ACL. For complete information, refer to the Cisco MDS 9000 Family CLI Configuration Guide.

You can apply IPv6-ACLs to VSAN interfaces, the management interface, Gigabit Ethernet interfaces on IPS modules and MPS-14/2 modules, and Ethernet PortChannel interfaces. However, if IPv6-ACLs are already configured in a Gigabit Ethernet interface, you cannot add this interface to a Ethernet PortChannel group.


Caution Do not apply IPv6-ACLs to just one member of a PortChannel group. Apply IPv6-ACLs to the entire channel group.

Use only the TCP or ICMP options when configuring IPv6-ACLs on Gigabit Ethernet interfaces.

Configure the order of conditions accurately. Because the IPv6-ACL filters are applied sequentially to the IP flows, the first match determines the action taken. Subsequent matches are not considered. Be sure to configure the most important condition first. If no conditions match, the software drops the packet.

Examples

The following example configures an IPv6-ACL called List, enters IPv6-ACL submode, and adds an entry that permits IPv6 traffic from any source address to any destination address:


switch# config terminal
switch(config)# ipv6 access-list List1
sswitch(config-ipv6-acl)# permit tcp any any

The following example removes a permit condition set for any destination prefix on a specified UDP host:

switch# config terminal
switch(config)# ipv6 access-list List1
switch(config-ipv6-acl)# no permit udp host 2001:db8:200d::4000 any

The following example removes the IPv6-ACL called List1 and all its entries:

switch# config terminal
switch(config)# no ipv6 access-list List1

power redundancy-mode

To configure the capacity of the power supplies on the Cisco MDS 9500 Family of switches, use the power redundancy-mode command in configuration mode. Use the no form of the command to negate the command or revert to factory defaults.

power redundancy-mode {combined [force] | redundant}

no power redundancy-mode {combined [force] | redundant}

Syntax Description

combined

Configures power supply redundancy mode as combined.

force

Forces combined mode without prompting.

redundant

Configures power supply redundancy mode as redundant.


Defaults

Redundant mode.

Command Modes

Configuration mode.

Command History

Release
Modification

1.0(2)

This command was introduced.


Usage Guidelines

If power supplies with different capacities are installed in the switch, the total power available differs based on the configured mode:

In redundant mode, the total power is the lesser of the two power supply capacities. This reserves enough power to keep the system powered on in case of a power supply failure. This is the recommended or default mode.

In combined mode, the total power is twice the lesser of the two power supply capacities. In case of a power supply failure, the entire system could be shut down, depending on the power usage at that time.

When a new power supply is installed, the switch automatically detects the power supply capacity. If the new power supply has a capacity that is lower than the current power usage in the switch and the power supplies are configured in redundant mode, the new power supply will be shut down.

When you change the configuration from combined to redundant mode and the system detects a power supply that has a capacity lower than the current usage, the power supply is shut down. If both power supplies have a lower capacity than the current system usage, the configuration is not allowed.

Examples

The following examples demonstrate how the power supply redundancy mode could be set:

switch(config)# power redundancy-mode combined
WARNING: This mode can cause service disruptions in case of a power supply failure. 
Proceed ? [y/n] y
switch(config)# power redundancy-mode redundant
