Терез 88pl99ace1Cisco Catalyst 9300 Series Switches, kНет. Нет.wn for their robust performance and extensive enterprise features, are a crucial part of many network infrastructures. However, when issues arise or administrators need to wipe configurations and restore default settings, performing a factory reset becomes essential. This guide covers all aspects of the Cisco 9300factory reset process, along with important technical details and additional context on when and why to use these reset procedures.

When to Use a Factory Reset on a Cisco 9300

Before proceeding with a factory reset, it’s vital to understand scenarios where this action is appropriate. A factory reset deletes all custom configurations, returning the switch to its default state. Scenarios may include:

• Re-deployment: Preparing a switch for use in a new network by removing old configurations.

• Troubleshooting Persistent Issues: Resolving unresolved operational issues that haven’t responded to standard troubleshooting steps.

• Security Concerns: Erasing all data to prevent unauthorized access if the switch is being repurposed or decommissioned.

Prerequisites for Factory Reset

Before performing a factory reset, ensure the following steps are completed:

• Back Up Configurations: Save the current configuration to a secure location if you plan to restore or reference settings later.

• Understand the Reset Impact: Be aware that a factory reset removes all configurations, including VLANs, IP settings, and access credentials.

• Access the Console: Factory reset may require console access to confirm settings and monitor the reset process.

Factory Reset Methods for Cisco 9300

The Cisco Catalyst 9300 switches offer several methods to perform a factory reset, depending on the situation and available access. These include resetting from the console using CLI commands and the physical Mode button on the switch. Let’s explore each method:

Method 1: Factory Reset via CLI (Command-Line Interface(1)

This is the most commonly used reset method and requires console access to the switch. Follow these steps:

1. Access the switch’s console through an SSH or direct serial connection.

2. Log in with administrative privileges.

3. Enter privileged EXEC mode by typingВключить новые функцииand pressing Enter.

4. To clear the configuration and reset the switch, use the command:

write erase

5. Confirm by pressing Enter. This command removes the startup configuration file.

6. Next, reload the switch with:

reload

7. Upon reload, confirm that you want to proceed without saving the running configuration by enteringnoif prompted.

After the switch reboots, it will return to the factory default settings.

Method 2: Factory Reset Using the Mode Button

This method requires physical access to the switch. Follow these steps:

1. Ensure the switch is powered on.

2. Locate the Mode button on the front panel of the switch.

3. Press and hold the Mode button for about 10-15 seconds, until the Status LED blinks amber.

4. Release the Mode button, and the switch will reset to its factory default state.

This option is useful when CLI access is not possible or practical.

• Verify Configuration: Log in and check the running configuration to confirm settings have reset.

• Check VLANs: Ensure that VLAN configurations have been cleared.

• Restore IP Settings: Confirm that any prior IP settings have been removed.

Setting Up the Cisco 9300 After Factory Reset

After resetting, the Cisco 9300 is in its default configuration state. To set it up, follow these initial setup steps:

Step 1: Connect to the Console

Use an SSH client or serial console to access the switch interface and perform setup.

Step 2: Enter Setup Mode

Upon the first boot, the switch may automatically enter setup mode. Follow the prompts to configure basic settings.

Step 3: Configure Basic Network Settings

Use the CLI to configure essential network settings, including hostname, IP addresses, and VLANs, to prepare the switch for deployment.

Potential Issues and Troubleshooting After a Reset

Occasionally, issues may arise after a reset. Here are some common troubleshooting tips:

Problem: Unable to Access the Console

Solution: Check console cable connections, and ensure the SSH or serial session settings are correct. Also, verify that login credentials are correct.

Problem: Configuration Not Fully Reset

Solution: If some configurations appear to persist, perform a second factory reset and ensure all previous sessions have been closed.

Problem: No Network Connectivity After Reset

Solution: Recheck IP configurations and VLAN settings, as they may need to be reconfigured post-reset.
