Chapter 3 Message and Recovery Procedures

FM Messages

Error Message EXPRESS_SETUP-6-MODE_EXITED.

Explanation The Express Setup mode is no longer active.

Recommended Action No action is required.

FM Messages

This section contains the feature manager messages. The feature manager software module manages access control lists (ACLs). Most messages in this section are the result of a switch memory shortage, which includes hardware memory such as the ternary content addressable memory (TCAM) and label space versus CPU memory. Both kinds of memory shortages are described.

Error Message FM-1-INIT: Feature Manager subsystem initialization failure.

Note This message applies only to Catalyst 3550 switches.

Explanation The feature manager subsystem failed to initialize. The most likely cause is insufficient memory at initialization. Either the hardware has failed, or the wrong Cisco IOS image is installed.

Recommended Action Replace the failing hardware, or obtain the correct Cisco IOS image for this platform.

Error Message FM-2-NOMAP: Cannot create Feature Manager data structures for VLAN Map [chars].

Note This message applies only to Catalyst 3550 switches.

Explanation The feature manager could not allocate the data structures needed to describe a VLAN map in a form that can be loaded into hardware. This error is probably caused by a lack of free memory. [chars] is the VLAN map name.

Recommended Action Reduce other system activity to ease the memory demands.

Error Message FM-2-NOSB: Cannot create subblock for interface [chars].

Note This message applies only to Catalyst 3550 switches.

Explanation The feature manager was unable to save per-interface information needed for its correct operation. Some per-interface features, such as access groups or VLAN maps, will not be correctly configured. [chars] is the interface name.

Recommended Action Use a less complicated configuration that requires less memory.

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.
