FM Messages

Error Message FM-3-LABELERROR: Incorrect label to [chars] vlan label attribute copy callback srclabel [dec], dstlabel [dec].

Note This message applies only to Catalyst 3550 switches.

Explanation The feature manager attribute copy callback was called with an incorrect source or destination label. [chars] is the direction (input or output), the first [dec] is the source label value, and the second [dec] is the destination label value.

Recommended Action Copy the message exactly as it appears on the console or in the system log. Research and attempt to resolve the error by using the Output Interpreter. Enter the show running-configuser EXEC command to gather data that might help identify the nature of the error. Use the Bug Toolkit to look for similar reported problems. If you still require assistance, open a case with the TAC, or contact your Cisco technical support representative, and provide the representative with the gathered information. For more information about these online tools and about contacting Cisco, see the “Error Message Traceback Reports” section on page 2-7.

Error Message FM-3-MAXRECURSION: Too many ([dec]) levels of recursion while merging [chars] (code [dec]).

Note This message applies only to Catalyst 3550 switches.

Explanation The configuration is too complicated for the platform-specific ACL merge code to support. The most likely cause is too many separate access lists in a single VLAN map or policy map. The first [dec] is the number of levels of recursion. [chars] describes which stage of the merge encountered the problem; the stage can be one of these: VLAN map, Global Input, Global Output, or QoS Map. The second [dec] is an internal code number of the merge stage that encountered the problem.

Recommended Action Reduce the number IP or MAC access lists (counted separately) in any one VLAN or policy map to fewer than the number of levels reported by this log message.

Error Message FM-3-MERGEFAIL: [chars] ACL merge error [dec] ([chars]) on [chars] label [dec].

Note This message applies only to Catalyst 3550 switches.

Explanation The feature manager was unable to merge the configured features into a form suitable for loading into the hardware. Packets potentially affected by this feature are sent to the CPU for processing. The CPU processing needed to uphold the overflowed ACL severely degrades performance. The first [chars] is the ACL-type error (ip or mac), the first [dec] is the error code, the second [chars] is the message string for the preceding error code, the second [dec] is the label number, and the third [chars] is either input or output.

Recommended Action Reorganize the ACLs so that all entries fit into hardware. Use less complicated and fewer ACLs.

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.
