In RUCKUS ICX switches, the copy flash flash command is used to duplicate a firmware image from one flash partition to another. This is useful for maintaining consistent firmware versions across different boot partitions.

Command Syntax:

copy flash flash [primary | secondary]

Parameters:

primary: Specifies the primary flash partition.

secondary: Specifies the secondary flash partition.

Zero-touch stacking simplifies the process of forming a stack by automating the configuration. To ensure all devices join the stack seamlessly, the following prerequisites must be met:

Enable Stacking on All Devices:

Access each switch's CLI.

Enter global configuration mode: configure terminal.

Enable stacking by executing: stack enable.

Save the configuration with: write memory.

Ensure Units Have Clean Configurations:

It's crucial that switches have default configurations to prevent conflicts during the stacking process.

To reset a switch to its default settings:

Enter global configuration mode: configure terminal.

Execute the command: write erase.

Reload the switch to apply the default configuration: reload.

Additional Considerations:

Ensure all switches are running compatible firmware versions to prevent software mismatches.

Verify that stacking cables are correctly connected to facilitate proper communication between units.

To enable Open Shortest Path First (OSPF) globally on a RUCKUS ICX switch, the router ospf command is used. This command initiates OSPF routing processes, allowing the switch to participate in OSPF-based dynamic routing.

Steps to Enable OSPF Globally:

Access Global Configuration Mode:

Enter privileged EXEC mode and then global configuration mode:

enable

configure terminal

Enable OSPF Routing:

Activate the OSPF routing process:

router ospf

Assign OSPF Parameters:

Set the router ID (optional but recommended):

router-id

Specify OSPF areas and associate interfaces:

network area <area-id>

Configure OSPF on Interfaces:

Enter interface configuration mode for each interface participating in OSPF:

interface

ip ospf area <area-id>

Save Configuration:

Ensure the configuration persists after a reboot:

write memory

Example Configuration:

To configure OSPF with a router ID of 1.1.1.1 and include the network 192.168.1.0/24 in area 0:

configure terminal

router ospf

router-id 1.1.1.1

network 192.168.1.0 0.0.0.255 area 0

exit

interface ethernet 1/1/1

ip ospf area 0

exit

write memory

Considerations:

Licensing: Ensure the switch has the appropriate Layer 3 license to support OSPF.

Compatibility: Verify that the FastIron software version supports OSPF.

Network Planning: Properly design OSPF areas and hierarchies to optimize routing efficiency.

In RUCKUS ICX switches, certain VLAN IDs are reserved for system functions and cannot be used for user-defined VLANs. Specifically, the following VLAN IDs are reserved:

VLAN 0: Reserved for priority tagging.

VLAN 1: Default VLAN for untagged frames.

VLAN 4095: Reserved and cannot be used.

VLAN 4094: Reserved and cannot be used.

VLAN 4093: Reserved and cannot be used.

This totals to 5 reserved VLAN IDs.

These reservations are standard across many networking devices to ensure proper network operations and to avoid conflicts with system-level processes. It's important to note that while VLAN 1 is the default VLAN, it can be reassigned if necessary, but caution should be exercised to avoid disrupting network management and control traffic.

For detailed information on VLAN configuration and reserved VLAN IDs on RUCKUS ICX switches, please refer to the RUCKUS FastIron Layer 2 Switching Configuration Guide:

FastIron Layer 2 Switching Configuration Guide

This guide provides comprehensive information on VLAN management, including details on reserved VLAN IDs and best practices for VLAN configuration on RUCKUS ICX switches.

Understanding the Configuration:

The command aaa authentication login default radius local specifies that the switch will attempt RADIUS authentication first. If the RADIUS server is unavailable, it will fallback to the local username/password.

If the RADIUS server is operational, the local credentials will not be accepted, even over the console port.

Why Can't the Technician Log In?

The local username/password will only work if the RADIUS server is unreachable. In this scenario, the RADIUS server is functional, so the switch continues to authenticate through it and does not fall back to the local credentials.

This behavior is by design, as dictated by the configuration.

Solution:

If access to the console port using local credentials is a critical requirement, consider adjusting the configuration to prioritize local credentials. For example, use:

aaa authentication login default local radius

This configuration ensures that local credentials are tried first, with RADIUS as a secondary option.

To display license information on a RUCKUS ICX switch, the following CLI commands are utilized:

show version:

This command provides detailed information about the switch's software and hardware, including installed licenses.

Usage:

sql

Copy code

show version

Output Includes:

Software version

Boot code version

License level and status

Hardware model

show license:

This command displays specific details about all installed licenses on the switch.

Usage:

sql

Copy code

show license

Output Includes:

License type

Activation status

Feature set enabled by the license

Expiration date (if applicable)

Example Outputs:

show version:

SW: Version 08.0.95dT213

Boot-Monitor Image: 10.1.15T225

HW: ICX7150-48P

License: L3 Premium

This output indicates the switch is running software version 08.0.95dT213 with an active Layer 3 Premium license.

show license:

License Level: L3 Premium

License Type: Permanent

License Status: Active

This output confirms the Layer 3 Premium license is permanently active on the switch.

To determine the IP address of a device connected to a specific switch port on a RUCKUS ICX switch, the following commands can be utilized:

show lldp neighbor detail

This command provides detailed information about devices connected via LLDP, including their IP addresses.

Command Usage:

show lldp neighbor detail

Output Example:

Local Port: 1/1/2

Neighbor MAC: 60d0.2c1c.1cd0

System Name: RuckusAP

Management Address: 192.168.0.3

In this example, the Management Address field displays the IP address of the connected device on port 1/1/2.

show arp

The Address Resolution Protocol (ARP) table maps IP addresses to MAC addresses. By examining the ARP table, you can identify the IP address associated with a device's MAC address.

Command Usage:

show arp

Output Example:

IP Address MAC Address Type Age Port

192.168.0.3 60d0.2c1c.1cd0 Dynamic 0 1/1/2

Here, the IP address 192.168.0.3 is associated with the MAC address 60d0.2c1c.1cd0 on port 1/1/2.

Note: For the show lldp neighbor detail command to provide IP addresses, LLDP must be enabled on both the switch and the connected devices. Additionally, the devices should support LLDP and be configured to advertise their management addresses.
