Chapter 3 Message and Recovery Procedures

GBIC Messages

Error Message FRNTEND_CTRLR-2-SUB_INACTIVE: The front end controller [dec] is inactive.

Note This message applies only to Catalyst 3750 and 2975 switches.

Explanation The front-end controller that controls the LEDs, the PoE features, and the fan-control features is now inactive on the port controlled by the front-end controller. This does not affect the traffic on the port. [dec] is the controller number.

Recommended Action Reset the switch. If the problem is not resolved by resetting the switch, contact your Cisco technical support representative because there might be a problem with the switch.

GBIC Messages

This section contains Gigabit Interface Converter (GBIC) module identification and validation messages on Catalyst 3550 switches. When a GBIC module is inserted into the switch, the software reads information from the module that identifies its type, and for some types of GBIC modules, obtains additional information to validate the compatibility of the module.

Error Message GBIC_1000BASET-6-GBIC_1000BASET_DEFAULT_CONFIG: 1000BASE-T GBIC module is detected in [chars]. Speed and duplex will be autonegotiated.

Note This message applies only to Catalyst 3550 switches.

Explanation A 1000BASE-T GBIC module is detected in the slot, and its speed and duplex are automatically negotiated. [chars] is the slot in which the module is installed.

Recommended Action No action is required.

Error Message GBIC_1000BASET-6-GBIC_1000BASET_NO_CONFIG_DUPLEX: Configuration ignored. 1000-BaseT GBIC modules only support autonegotiation on duplex.

Note This message applies only to Catalyst 3550 switches.

Explanation Autonegotiation was not used. The 1000BASE-T GBIC modules only support autonegotiation on duplex.

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.
