Layer 3 Address Assignment:

Stack Interface (A): A stack interface is a virtual interface representing all members of a stack. It can be assigned a Layer 3 IP address for management or routing purposes.

Loopback (E): Loopback interfaces are virtual interfaces always "up" and used for routing, management, or stable endpoint addressing.

GRE Tunnels (F): GRE tunnels operate at Layer 3 and require IP addresses for both endpoints to encapsulate and route traffic.

Why Not Other Options?

B. VxLAN: VxLAN operates at Layer 2 over Layer 3 and does not require direct IP address assignment to itself.

C. Virtual LAN: VLANs are Layer 2 constructs; while they are associated with SVI (Switch Virtual Interfaces), they are not directly assigned an IP address.

D. Virtual Ethernet: Virtual Ethernet interfaces are typically Layer 2 and used within virtualized environments, not directly assigned Layer 3 addresses.

In network architecture, a collapsed aggregation and core design consolidates the aggregation and core layers into a single layer, simplifying the network and reducing latency. RUCKUS ICX switch models suitable for such designs include:

ICX7850:

Overview:

A high-performance, stackable switch designed for enterprise aggregation and core layers.

Key Features:

Supports up to 32 ports of 40/100 GbE, providing high-density connectivity.

Advanced stacking capabilities, allowing up to 12 switches to be stacked together for simplified management and scalability.

Dual hot-swappable power supplies and fans, ensuring high availability and reliability.

Use Case:

Ideal for organizations seeking to implement a collapsed core architecture with high bandwidth requirements and simplified network management.

Power over Ethernet (PoE) technology allows network switches to deliver electrical power to connected devices over standard Ethernet cables. The IEEE 802.3at standard, commonly known as PoE+, provides up to 30 watts of power per port. RUCKUS enhances this capability with a proprietary feature called PoE+ Overdrive, which increases the maximum power output per port.

With PoE+ Overdrive enabled, a PoE+ interface on RUCKUS ICX switches can deliver up to 45 watts of power over two pairs of wires. This enhancement is particularly beneficial for devices that require more power than the standard PoE+ provision, such as advanced wireless access points or video conferencing systems.

It's important to note that the actual power delivered to the powered device (PD) is slightly less due to cable losses. For instance, while the Power Sourcing Equipment (PSE) may supply 45 watts, the PD might receive approximately 35.5 watts. This ensures that devices receive sufficient power even after accounting for transmission losses.

The availability of PoE+ Overdrive and the maximum power output per port can vary depending on the specific ICX switch model. For example, the RUCKUS ICX 7650 supports PoE+ Overdrive with a maximum output of 45 watts per port. Similarly, the ICX 7150-48ZP model offers PoE+ Overdrive capabilities.

For detailed information on PoE+ Overdrive capabilities and supported models, refer to the "Ruckus Power over Ethernet (PoE) Interoperability" document.

In RUCKUS ICX switches, assigning an interface to an OSPF (Open Shortest Path First) area involves configuring the interface with the appropriate OSPF area command. The correct command to assign an interface to a specific OSPF area is:

ip ospf area <area-id>

For example, to assign an interface to area 0, you would enter interface configuration mode for the desired interface and execute:

ip ospf area 0

This command associates the interface with OSPF area 0, enabling OSPF routing on that interface within the specified area.

It's important to note that OSPF areas are logical groupings of networks and routers within an OSPF domain. Assigning interfaces to the correct OSPF areas is essential for efficient routing and network segmentation.

For comprehensive guidance on OSPF configuration, including assigning interfaces to areas, refer to the RUCKUS FastIron Configuration Guide.

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:

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:

In RUCKUS ICX switches, VLAN 1 is the default VLAN and is typically used for management purposes. By default, all ports are members of VLAN 1 as untagged. Attempting to configure VLAN 1 as tagged on a port can result in an error, as the system restricts tagging the default VLAN.

Understanding the Error:

RKUS-01(config)# vlan 1

RKUS-01(config-vlan-1)# tagged ethernet 1/2/1

Invalid input -> tagged ethernet 1/2/1

Type ? for a list

This error occurs because the switch does not allow tagging of the default VLAN (VLAN 1) on any interface.

Resolution:

Option 1: Use a Different VLAN for Tagging

Create a new VLAN (e.g., VLAN 2) and configure it as tagged on the desired port.

RKUS-01(config)# vlan 2

RKUS-01(config-vlan-2)# tagged ethernet 1/2/1

Option 2: Change the Default VLAN ID

If you must use VLAN 1 as tagged, you can change the default VLAN ID to another VLAN (e.g., VLAN 2), allowing VLAN 1 to be configured as tagged.

RKUS-01(config)# default-vlan-id 2

RKUS-01(config)# vlan 1

RKUS-01(config-vlan-1)# tagged ethernet 1/2/1

The inline power poe-ha command on RUCKUS ICX switches enables two key Power over Ethernet (PoE) features:

Fast Boot PoE: This feature ensures that PoE power is delivered to connected devices immediately upon switch startup, without waiting for the entire system to boot up. This is crucial for devices that need to be operational as soon as possible, such as IP phones or security cameras. To enable Fast Boot PoE, enter interface configuration mode and execute the command:

inline power poe-ha

This command ensures that PoE is delivered promptly during the boot process.

Perpetual PoE: This feature maintains PoE power to connected devices even when the switch undergoes a soft reboot or firmware upgrade. It ensures uninterrupted power delivery, preventing devices from losing power during such events. To enable Perpetual PoE, use the same command in interface configuration mode:

By configuring this command, the switch provides continuous PoE power during reboots.

For more detailed information on these features and their configuration, refer to the RUCKUS Community Forum post titled "Things to consider about PoE at a glance, when deploying."
