# clns host

#### Syntax

clns host name nsap

no clns host name

#### Release Information

Command introduced before JunosE Release 7.1.0.

#### Description

Defines a name-to-NSAP mapping that can then be used with commands requiring NSAPs. Enables dynamic resolution of hostnames to system IDs (within the NSAP address). The hostname mapping is sent in the LSPs within the dynamic hostname TLV tuple. Display the TLV by issuing the show isis database detail command. Use the show hosts command to display the mapping. The no version restores the default of no mapping defined.

#### Options

- name—Name for the NSAP; first character can be either a letter or a number. If a number is used, the operations you can perform are limited.
- nsap—NSAP to which that name maps

#### Mode
