RUCKUS RCNI - RUCKUS Certified Networking Implementer Exam

To enable IPv6 functionality on a RUCKUS ICX switch, you must activate IPv6 unicast routing globally. This allows the switch to forward IPv6 packets and participate in IPv6 routing.

Steps to Enable IPv6 Unicast Routing:

Access the Switch's Command-Line Interface (CLI):

Connect to the switch via console, SSH, or Telnet.

Enter privileged EXEC mode:

plaintext

Copy code

enable

Enter Global Configuration Mode:

Switch to global configuration mode:

plaintext

Copy code

configure terminal

Enable IPv6 Unicast Routing:

Activate IPv6 unicast routing:

ipv6 unicast-routing

Configure IPv6 Addresses on Interfaces (Optional):

Assign IPv6 addresses to the desired interfaces:

interface ethernet 1/1/1

ipv6 address 2001:db8::1/64

Verify the Configuration:

Exit to privileged EXEC mode and display the running configuration to confirm:

end

show running-config

References:

For detailed information on configuring IPv6 addresses, refer to the RUCKUS FastIron Layer 3 Routing Configuration Guide: Configuring a global or site-local IPv6 address with a manually configured interface ID

By following these steps, you enable the switch to handle IPv6 traffic, facilitating IPv6 communication within your network.

To monitor and manage the PoE power budget on RUCKUS ICX switches, the following commands are utilized:

show inline power Command:

Purpose: Displays a summary of the PoE status, including total power capacity, power consumption, and available power.

Usage:

Access the switch's command-line interface (CLI).

Enter the command:

plaintext

Copy code

show inline power

Output Details:

Power Capacity: Total PoE power available on the switch.

Power Allocations: Power consumption per port, indicating which ports are supplying power to connected devices.

Example Output:

Power Capacity: Total is 124000 mWatts. Current Free is 64000 mWatts.

Understanding CLI Levels:

The ping command is used to test connectivity to other devices by sending ICMP echo requests.

It can only be executed from the privileged EXEC mode, which is indicated by the Router# prompt.

Why Other Prompts Don't Work:

A. Router(config-if-mgmt-1)#: This is the interface configuration mode for the management port and does not allow execution of diagnostic commands like ping.

B. Router(config)#: This is the global configuration mode, which is used to configure the switch but does not support diagnostic commands.

D. Router(config-if-e1000-1/1/1)#: This is the interface configuration mode for Ethernet 1/1/1, which also does not allow execution of ping.

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.

In RUCKUS ICX devices, interfaces can be configured to support both IPv4 and IPv6 addresses concurrently, a setup known as dual-stack configuration. This allows the interface to handle both IPv4 and IPv6 traffic simultaneously.

Given the configuration:

ICX-Router (config)# ipv6 unicast-routing

ICX-Router (config)# interface ethernet 1/3/1

ICX-Router (config-if-e1000-1/3/1)# ip address 10.172.10.1/24

ICX-Router (config-if-e1000-1/3/1)# ipv6 address 2001:db8:12d:1300::/64

The command ipv6 unicast-routing enables IPv6 routing on the device globally.

Within the interface configuration mode for Ethernet 1/3/1, the ip address command assigns an IPv4 address, and the ipv6 address command assigns an IPv6 address to the same interface.

This configuration allows the interface to transmit and receive both IPv4 and IPv6 traffic simultaneously, facilitating communication in a dual-stack network environment.

Therefore, the correct statement is:

B. The interface will transmit and receive both IPv4 and IPv6 traffic simultaneously.
