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."

To install a feature license on a RUCKUS ICX switch running FastIron 08.0.95, follow these steps using the Command Line Interface (CLI):

Obtain the License Key:

Purchase the desired feature license from RUCKUS.

Receive the license key, typically provided as a string of characters.

Access the Switch CLI:

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

Enter privileged EXEC mode:

enable

Enter Global Configuration Mode:

Access global configuration mode:

configure terminal

Install the License Key:

Enter the license key using the following command:

In Virtual Router Redundancy Protocol Extended (VRRP-E) configurations on RUCKUS ICX switches, the master router sends hello messages at regular intervals to indicate its active status. By default, these hello messages are sent every 1 second.

Key Points:

Hello Interval: The frequency at which the master router sends hello messages to backup routers.

Default Value: 1 second.

Purpose: To inform backup routers of the master's presence and operational status. If backup routers do not receive hello messages within a specified dead interval, they assume the master is down and initiate a failover.

Configuration:

Viewing Current Settings:

To display the current VRRP-E configuration, including hello intervals:

sql

Copy code

show vrrp

Modifying the Hello Interval:

To change the hello interval, enter VRRP-E configuration mode for the specific virtual router instance and use the following command:

php

Copy code

vrrp advertisement-interval

: Virtual Router ID.

: Desired interval in seconds.

Example:

To set the hello interval to 2 seconds for VRID 1:

bash

Copy code

enable

configure terminal

interface ethernet 1/1/1

vrrp 1

advertisement-interval 2

exit

write memory

Considerations:

Network Stability: Setting the hello interval too low can lead to unnecessary failovers due to transient network issues. Conversely, setting it too high can delay failover detection.

Consistency: Ensure that all routers in the VRRP-E group have consistent hello and dead interval settings to prevent configuration mismatches.

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.
