ILPOWER Messages

Error Message ILPOWER-5-IEEE-DISCONNECT: Interface [chars]: PD removed.

Note This message applies only to Catalyst 3750 and 3560 switches.

Explanation The powered device is no longer connected to the switch or that the connected powered device is being powered by an external AC power source. The switch is no longer providing power to the port. [chars] is the interface.

Recommended Action No action is required.

Error Message ILPOWER-5-ILPOWER_POWER_CDP_SHUT: Interface [chars]: inline power shut

Note This message applies only to Catalyst 3750, 3560, and 3550 switches.

Explanation Inline power is shut down because CDP consumption power on this Power over Ethernet (PoE) port is greater than the allocation power, the hardware interface limit, the user-configured maximum power, or the available power on this switch. [chars] is the interface.

Recommended Action No action is required.

Error Message ILPOWER-5-ILPOWER_POWER_DENY: Interface [chars]: inline power denied.

Note This message applies only to Catalyst 3750 and 3560 switches.

Explanation There is not enough power remaining in the switch to supply to the PoE port. [chars] is the interface.

Recommended Action Connect the powered device to an external AC power source.

Error Message ILPOWER-5-ILPOWER_POWER_DENY:Interface [chars]:inline power denied

Note This message applies only to Catalyst 3550-24PWR switches.

Explanation The PoE request was denied because the switch does not have enough power left to support the request. [chars] is the interface number.

Recommended Action No action is required.

3750 specifications

The Cisco Systems 3750 series is a family of enterprise-class stackable switches that were designed to provide high-performance networking solutions for organizations requiring robust management features, security, and scalability. Known for their reliability and advanced capabilities, the 3750 series is particularly aimed at accommodating the demands of LAN environments in organizations ranging from small businesses to large enterprises.

One of the defining features of the Cisco 3750 series is its StackWise technology. This innovative feature enables the stacking of up to nine switches together, allowing them to function as a single logical unit. This results in simplified management, higher redundancy, and increased scalability. The StackWise technology allows for seamless failover and enhanced bandwidth between the stacked switches.

In terms of performance, the 3750 series supports Layer 2 and Layer 3 switching, offering routing capabilities to handle both traditional and modern network demands. It is equipped with advanced Quality of Service (QoS) features, ensuring that critical applications such as voice and video are prioritized for optimal performance.

The Cisco 3750 also features extensive security capabilities. It incorporates features such as IEEE 802.1X authentication, DHCP snooping, and dynamic ARP inspection to protect against unauthorized access and various network attacks. These enhancements help maintain data integrity and secure communications across the network.

Another noteworthy characteristic of the 3750 series is its support for Power over Ethernet (PoE). PoE allows for the delivery of power over Ethernet cables to connected devices, such as IP phones and wireless access points, facilitating simpler installations and reducing the need for additional power outlets.

The Cisco 3750 series also provides a comprehensive set of management tools. With features like Cisco's Embedded Event Manager (EEM) and extensive SNMP support, network administrators can efficiently monitor and manage network performance, troubleshoot issues, and maintain high availability.

Additionally, the series is compatible with Cisco's IOS software, which provides a rich set of features, including advanced routing protocols, multicast support, and extensive security options, further enhancing the functionality and versatility of the switches.

Overall, the Cisco Systems 3750 series stands out for its stackable design, high-performance features, security capabilities, and management tools, making it a popular choice for organizations looking for dependable and scalable networking solutions.
