Parameters

alias address-range <ADDRESS-RANGE-ALIAS-NAME> <STARTING-IP> to <ENDING-IP>
address-range <ADRESS-RANGE-ALIAS-NAME> Creates a new address-range alias for this RF Domain. Or associates an existing address-range alias with this RF Domain. An address-range alias maps a name to a range of IP addresses.
  • <ADRESS-RANGE-ALIAS-NAME> – Specify the address range alias name.
Note: Alias name should begin with ‘$‘.
<STARTING-IP> to <ENDING-IP> Associates a range of IP addresses with this address range alias
  • <STARTING-IP> – Specify the first IP address in the range.
    • to <ENDING-IP> – Specify the last IP address in the range.
Note: Aliases defined at any given level can be overridden at the next lower level. For example, a global alias can be redefined on a selected set of RF Domains, profiles, or devices. Overrides applied at the device level take precedence.
 
alias encrypted-string <ENCRYPTED-STRING-ALIAS-NAME> [0|2] <LINE>
encrypted-string <ENCRYPTED-STRING-ALIAS-NAME> Creates an alias for an encrypted string. Use this alias for string configuration values that are encrypted when "password-encryption" is enabled. For example, in the management-policy, use it to define the SNMP community string.
  • <ENCRYPTED-STRING-ALIAS-NAME> – Specify the encrypted-string alias name.
Note: Alias name should begin with ‘$‘.
[0|2] <LINE> Configures the value associated with the alias name specified in the previous step
  • [0|2] <LINE> – Configures the alias value
Note, if password-encryption is enabled, in the show > running-config output, this clear text is displayed as an encrypted string, as shown below:
nx9500-6C8809(config)#show running-config
!...............................
alias encrypted-string $enString 2 fABMK2is7UToNiZE3MQXbgAAA
AxB0ZIysdqsEJwr6AH/Da//
!
--More--
nx9500-6C8809

In the above output, the ‘2‘ displayed before the encrypted-string alias value indicates that the displayed text is encrypted and not a clear text.

However, if password-encryption is disabled the clear text is displayed as is:
nx9500-6C8809(config)#show running-config
!...............................
!
alias encrypted-string $enString 0 test11223344
!
--More--
nx9500-6C8809

For more information on enabling password-encryption, see password-encryption.

 
alias hashed-string <HASHED-STRING-ALIAS-NAME> <LINE>
hashed-string <HASHED-STRING-ALIAS-NAME> Creates an alias for a hashed string. Use this alias for configuration values that are hashed string, such as passwords. For example, in the management-policy, use it to define the privilege mode password. For more information, see privilege-mode-password.
  • <HASHED-STRING-ALIAS-NAME> – Specify the hashed-string alias name.
Note: Alias name should begin with ‘$‘.
<LINE> Configures the hashed-string value associated with this alias.

In the following examples the global aliases ‘$kerberos‘ and ‘$TestVLANAlias‘ are associated with the RF Domain ‘test‘ and overrides applied:

nx9500-6C8809(config-rf-domain-test)#alias network-service $kerberos proto tcp 749 750 80

nx9500-6C8809(config-rf-domain-test)#alias vlan $TestVLANAlias 10

Example 1:

In the following examples, the network-group alias ‘$test‘ is configured to include hosts 192.168.1.10 and 192.168.1.11, networks 192.168.2.0/24 and 192.168.3.0/24 and address-range 192.168.4.10 to 192.168.4.20. 

nx9500-6C8809(config)#alias network-group $test host 192.168.1.10 192.168.1.11

nx9500-6C8809(config)#alias network-group $test network 192.168.2.0/24 192.168.3.0/24

nx9500-6C8809(config)#alias network-group $test address-range 192.168.4.10 to 192.168.4.20

Associate this network-group alias ‘$test‘ to the RF Domain ‘test‘ and override the ‘host‘ element of the alias.

nx9500-6C8809(config-rf-domain-test)#alias network-group $test host 192.168.10.10

nx9500-6C8809#show context

  alias network-group $test address-range 192.168.4.10 to 192.168.4.20
  alias vlan $TestVLANAlias 10
nx9500-6C8809(config-rf-domain-test)#

In the preceding example, the ‘host‘ element of the network-group alias ‘$test‘ has been overridden. But the ‘network‘ and ‘address-range‘ elements have been retained as is.
