Cisco MDS 9000 Series Command Reference, Release 9.x

data-pattern-file

To configure data pattern file for a SAN tuner extension N port, use the data-pattern-file command in interface configuration submode. To remove data pattern file, use the no form of the command.

data-pattern-file filename

no data-pattern-file

Syntax Description


`filename`	Specifies the data pattern file name.

Command Default

All zero pattern.

Command Modes

SAN extension N port configuration submode.

Command History


Release	Modification
2.0(x)	This command was introduced.

Usage Guidelines

By default, an all-zero pattern is used as the pattern for data generated by the virtual N ports. You can optionally specify a file as the data pattern to be generated by selecting a data pattern file from one of three locations: the bootflash: directory, the volatile: directory, or the slot0: directory. This option is especially useful when testing compression over FCIP links. You can also use Canterbury corpus or artificial corpus files for benchmarking purposes.

Examples

The following example configures the data pattern file for an N port:


switch# san-ext-tuner
switch(san-ext)# nWWN 10:00:00:00:00:00:00:00
switch(san-ext)# nport pwwn 12:00:00:00:00:00:00:56 vsan 13 interface gigabitethernet 1/2
switch(san-ext-nport)# data-pattern-file bootflash://DataPatternFile

Command History


Release	Modification
1.0(2	This command was introduced.
2.1(1a)	Added debug, log, and modflash keywords.

Usage Guidelines

When you delete a file, the software erases the file.

If you attempt to delete the configuration file or image specified by the CONFIG_FILE or BOOTLDR environment variable, the system prompts you to confirm the deletion. Also, if you attempt to delete the last valid system image specified in the BOOT environment variable, the system prompts you to confirm the deletion.

Caution

If you specify a directory, the delete command deletes the entire directory and all its contents.

Examples

The following example deletes the file named test from the flash card inserted in slot 0:


switch# delete slot0:test
Delete slot0:test? [confirm]

The following example deletes a file from a directory:

delete ca-certificate

To delete certificate authority certificates, use the delete ca-certificate command in trust point configuration submode.

delete ca-certificate

Syntax Description

This command has no arguments or keywords.

Command Default

None.

Command Modes

Trust point configuration submode.

Command History


Release	Modification
3.0(1)	This command was introduced.

Usage Guidelines

This command deletes the CA certificate or certificate chain corresponding to the trust point CA. As a result, the trust point CA is no longer trusted. If there is an identity certificate form the CA, you should delete it before attempting to delete the CA certificate. Doing so prevents the accidental deletion of a CA certificate when you have not yet deleted the identity certificate from that CA. This action may be necessary when you do not want to trust the CA any more for a reason such as the CA is compromised or the CA certificate is already expired, with the latter being a very rare event.

Note

The trust point configuration, certificates, and key pair configurations are made persistent only after saving to the startup configuration. To be consistent with this configuration behavior, the delete behavior is also the same. That is, the deletions are made persistent only after saving to the startup configuration. Use the copy running-config startup-config command to make the certificate and key pair deletions persistent.

Examples

The following example shows how to delete a certificate authority certificate:


switch# config terminal
switch(config)# crypto ca trustpoint admin-ca
switch(config-trustpoint)# delete ca-certificate

Related Commands


Command	Description
delete certificate	Deletes the identity certificate.
delete crl	Deletes the crl from the trustpoint.

delete certificate

To delete the identity certificate, use the delete certificate command in trust point configuration submode.

delete certificate [force]

Syntax Description


force	(Optional) Forces the deletion of the identity certificate.

Command Default

None.

Command Modes

Trust point configuration submode.

Command History


Release	Modification
3.0(1)	This command was introduced.

Usage Guidelines

Use this command to delete the identity certificate from the trust point CA. This action may be necessary when the identity certificate expires or the corresponding key pair is compromised. Applications will be left without any identity certificate to use after the deletion of the last or the only identity certificate present. Accordingly, an error message is generated if the certificate being deleted is the last or only identity certificate present. If needed, the deletion can still be accomplished by forcing it using the force option.

Note

The trust point configuration, certificates, and key pair configurations are made persistent only after saving to the startup configuration. To be consistent with this configuration behavior, the delete behavior is also the same. That is, the deletions are made persistent only after saving to the startup configuration. Use the copy running-config startup-config command to make the certificate and key pair deletions persistent.

Examples

The following example shows how to delete the identity certificate:


switch# config terminal
switch(config)# crypto ca trustpoint admin-ca
switch(config-trustpoint)# delete certificate

The following example shows how to force the deletion of the identity certificate:


switch(config-trustpoint)# delete certificate force

Related Commands


Command	Description
delete ca-certificate	Deletes the certificate authority certificate.
delete crl	Deletes the crl from the trustpoint.

delete crl

To delete the crl from the trustpoint, use the delete crl command in trust point configuration submode.

Command Default

None.

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.

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 List1, enters IPv6-ACL submode, and adds an entry to deny TCP traffic from any source address to any destination address:


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

The following example removes a deny 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 deny 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

Command History


Release	Modification
8.5(1)	The default device alias mode was changed to enhanced mode.
3.1(1)	This command was introduced.

Usage Guidelines

When a device alias is configured in basic mode, all the applications operate like 3.0 switches. For example, when you attempt to configure the device aliases, immediately the device alias are expanded to a PWWN. This operation continues until the mode is changed to enhanced.

When a device alias is configured in enhanced mode, all the applications accept a device alias name in its native format, instead of expanding the device alias to a PWWN, the device alias name is stored in the configuration and distributed in its native device alias format.

To use enhanced mode, all switches in the fabric must be running in the Cisco SAN-OS Release 3.1(1) or later, or NX-OS 4.1(1b) later.

Note

Enhanced mode, or native device alias based configurations are not accepted in interop mode. VSANs. IVR zoneset activation will fail in interop mode VSANs if the corresponding zones have native device alias-based members

Examples

The following example shows how to configure the device alias in enhanced mode:


switch# config terminal

When autolearn is enabled, the system automatically creates the DPVM database by learning about devices currently logged or newly logged devices with a VSAN. This is a quick way to create the DPVM which can later be edited. Autolearn features include the following:

An autolearned entry is created by adding the device PWWN and VSAN to the active DPVM database.
The active DPVM database must be present when autolearning is enabled.
Autolearned entries can be deleted from the active DPVM database by the user until autolearning is disabled. Autolearned entries are not permanent in the active DPVM database until autolearning is disabled.
If a device logs out when autolearning is enabled, the device entry is deleted from the active DPVM database.
If a particular device logs into the switch multiple times through different ports, then only the VSAN corresponding to last login is associated with the device.
Autolearn entries do not override previously configured activate entries.
