 This command was introduced. 
 		 
    
 
    
  
 
 
 
 
 
 
 
 
  
 
 Usage Guidelines 
 
  
 
 Use the authentication command to assign a password in the authentication of a hello protocol data unit. Only one authentication keychain 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 NX-OS Security Configuration Guide for your platform for information about keychains. 
 
 
 
   
 
 
 
 
  
 
 Note A level specification is not required. 
 
 
 
  
 
 This command requires an Enhanced Layer 2 license.

 Usage Guidelines 
 
  
 
 You do not have to manually assign a switch ID unless you are running a virtual port channel plus (vPC+) because the system assigns a switch ID for you when you enable FabricPath. 
 
 
 
   
 
 
 
 
  
 
 Note For more information about vPC+, see the fabricpath switch-id (vpc-domain configuration mode) command.

 Usage Guidelines 
 
  
 
 You do not have to manually assign a switch ID (unless you are running a vPC+); the system assigns a switch ID for you when you enable FabricPath. 
 
 
 
   
 
 
 
 
  
 
 Note You must assign the same vPC+ switch ID to each of the two vPC+ peer devices before they can form an adjacency. 
 
 
 
  
 
 This command requires an Enhanced Layer 2 license. 
 
  
 
 Examples 
 
  
 
 This example shows how to configure a vPC+ switch ID on a FabricPath-enabled device: 
 
  
 
 
  
switch# configure terminal

 Examples 
 
  
 
 This example shows how to configure the delay for a new switch ID to be propagated throughout the network before that value becomes available and permanent: 
 
  
 
 
  
switch# configure terminal

 
 
 
  
 
 
  
switch(config)# fabricpath timers allocate-delay 600

 
 
 
  
 
 
  
switch(config)#

 
 
 
  
 
 
  
 
 
 
  
 
 This example shows how to configure the link bringup delay to detect conflicts in the switch ID. If the system finds a conflict, the system takes some time to resolve the conflict and to bring FabricPath to an operational state: 
 
  
 
 
  
switch# configure terminal

 
 
 
  
 
 
  
switch(config)# fabricpath timers linkup-delay 600

 
 
 
  
 
 
  
switch(config)#

 
 
 
  
 
 
  
 
 
 
  
 
 This example shows how to configure the delay for propagating a transitioned value in the network; during this period, all old and new switch ID values exist in the network. This transition lasts only until the link comes up and the system checks to see if the network has two identical switch IDs. 
 
  
 
 
  
switch# configure terminal

 
 
 
  
 
 
  
switch(config)# fabricpath timers transition-delay 600

 
 
 
  
 
 
  
switch(config)#
