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 the "Command Modes" section to determine the appropriate mode for each command. For more information, refer to the Cisco MDS 9000 Family Configuration Guide.

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

This command was introduced in Cisco MDS SAN-OS Release 1.1(1).

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 merely 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.


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

This command was introduced in Cisco MDS SAN-OS Release 1.1(1).

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 10.1.1.1

The following command deletes the assigned peer port information.

switch(config-if)# no peer-info ipaddr 10.10.1.1 

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 10.1.1.1 port 3000

The following command deletes the assigned peer port information.

switch(config-if)# no peer-info ipaddr 10.1.1.1 port 2000

In this case, you need to manually populate the port security database by individually securing each port.

If the auto-learn option is enabled on a VSAN, you cannot activate the database for that VSAN without the force option.

Examples

The following example activates the port security database for the specified VSAN, and automatically enables autolearning.

switch# config terminal
switch(config)# port-security activate vsan 1

You cannot block or prohibit CUP port (0XFE).

If you prohibit ports, the specified ports are prevented from communicating with each other. Unimplemented ports are always prohibited.

Examples

The following example disables a port address and retains it in the operationally down state.

switch# config terminal
switch(config)# ficon vsan 2
switch(config-ficon)# portaddress 1 
switch(config-ficon-portaddr)# block

The following example enables the selected port address and reverts to the factory default of the port address not being blocked.

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

This command was introduced in Cisco MDS SAN-OS Release 1.0(2).

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
