This chapter describes the Cisco NX-OS FabricPath commands that begin with A.

authentication-check (FabricPath)

To enable an authentication check on received protocol data units (PDUs), use the authentication-check command. To return to the default setting, use the no form of this command.

authentication-check

no authentication-check

Syntax Description

This command has no arguments or keywords.

Command Default

Enabled

Command Modes

FabricPath IS-IS configuration mode

Command History

Release	Modification
5.1(3)N1(1)	This command was introduced.

Usage Guidelines

This command requires an Enhanced Layer 2 license.

Examples

This example shows how to enable an authentication check on received PDUs:

switch# configure terminal

Enter configuration commands, one per line.  End with CNTL/Z.

switch(config)# fabricpath domain default

switch(config-fabricpath-isis)# authentication-check

switch(config-fabricpath-isis)#

Related Commands

Command	Description
show fabricpath isis	Displays FabricPath IS-IS information.

authentication key-chain (FabricPath)

To configure an authentication keychain between FabricPath devices, use the authentication key-chain command. To return to the default setting, use the no form of this command.

authentication key-chain auth-key-chain-name

no authentication key-chain auth-key-chain-name

Syntax Description

keychain-name

Authentication keychain. The maximum size is 63 alphanumeric characters.

Defaults

None

Command Modes

FabricPath IS-IS configuration mode

Command History

Release	Modification
5.1(3)N1(1)	This command was introduced.

Usage Guidelines

Use the authentication key-chain command to assign a password in the authentication of a hello protocol data unit. Only one authentication key-chain is applied to an IS-IS interface at one time. If you configure a second authentication command, the first is overridden. You can specify authentication for an entire instance of IS-IS instead of at the interface level by using the authentication command.

See the Cisco Nexus 5000 Series NX-OS Security Configuration Guide for information about keychains.

This command requires an Enhanced Layer 2 license.

Examples

This example shows how to configure an authentication keychain string for edge device authentication:

switch# configure terminal

Enter configuration commands, one per line.  End with CNTL/Z.

switch(config)# fabricpath domain default

switch(config-fabricpath-isis)# authentication key-chain fabrickeys

switch(config-fabricpath-isis)#

Related Commands

Command	Description
show fabricpath isis	Displays FabricPath IS-IS information.

authentication-type (FabricPath)

To configure an authentication type, use the authentication-type command. To return to the default setting, use the no form of this command.

authentication-type {cleartext | md5}

no authentication-type {cleartext | md5}

Syntax Description

cleartext	Specifies the cleartext authentication method.
md5	Specifies the Message Digest (MD5) authentication.

Command Default

Enabled

Command Modes

FabricPath IS-IS configuration mode

Command History

Release	Modification
5.1(3)N1(1)	This command was introduced.

Usage Guidelines

Use the authentication-type command to configure the authentication type for hello protocol data units (PDUs) on an interface.

This command requires an Enhanced Layer 2 license.

Examples

This example shows how to specify cleartext authentication:

switch# configure terminal

Enter configuration commands, one per line.  End with CNTL/Z.

switch(config)# fabricpath domain default

switch(config-fabricpath-isis)# authentication-type cleartext

switch(config-fabricpath-isis)#

This example shows how to specify Message Digest (MD5) authentication:

switch# configure terminal

Enter configuration commands, one per line.  End with CNTL/Z.

switch(config)# fabricpath domain default

switch(config-fabricpath-isis)# authentication-type md5

switch(config-fabricpath-isis)#
