Best Practices for Configuring a Hostname in Cisco CLI: Guidelines for Naming Conventions

When a hostname is configured through the Cisco CLI, which three naming conventions are part of the guidelines?

When configuring a hostname through the Cisco Command Line Interface (CLI), there are several guidelines to follow for naming conventions.

The three important naming conventions are:

1. Start with a letter: The hostname should always start with a letter, specifically an alphabetic character. It cannot begin with a number or any special characters.

2. Use only alphanumeric characters: The hostname should only contain alphanumeric characters, meaning it can consist of letters (both uppercase and lowercase) and numbers. Special characters such as symbols and spaces are not allowed.

3. Limit the length: The hostname should be limited to a maximum of 63 characters. It is recommended to keep the hostname concise and easily recognizable for better management.

By following these naming conventions, you can ensure that the configured hostname is valid and compatible with Cisco devices.
