Chapter 3 Message and Recovery Procedures

FRNTEND_CTRLR Messages

Error Message FM-4-EXCESSSECONDARY: More than [dec] secondary IP addresses configured on interface [chars].

Note This message applies only to Catalyst 3550 switches.

Explanation When secondary IP addresses are configured on an interface and you enable Internet Control Message Protocol (ICMP) redirects for packets received on that interface, the ICMP redirect function on the CPU is not usually notified of packets sent between two different subnets on the same interface. If too many secondary IP addresses are configured on the interface this message is logged, and in addition to being notified about packets that cause the generation of an ICMP redirect, the CPU is also notified about every packet routed between two different subnets that are both on the interface. No ICMP redirects will be sent in error, but the CPU usage might increase because of the additional notifications. [dec] is the limit of secondary IP addresses, and [chars] is the specified interface.

Recommended Action You can use the no ip redirects interface configuration command on the interface named in the message to reduce the CPU load on the system.

Error Message FM-7-TRANSDEF: No augmentation function found for VMR.

Note This message applies only to Catalyst 3550 switches.

Explanation An internal error occurred. An ACL was not correctly interpreted. The value-mask result (VMR) is incorrect.

Recommended Action Find out more about the error by using the show tech-supportprivileged EXEC command and by copying the error message exactly as it appears on the console or system log and entering it in the Output Interpreter tool. Use the Bug Toolkit to look for similar reported problems. For more information about these online tools and about contacting Cisco, see the “Error Message Traceback Reports” section on page 2-7for more information.

Error Message FRNTEND_CTRLR-1-MGR_TXQ_FULL: The front end controller Tx queue reached watermark level

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

Explanation There are too many messages in the queue between the front-end controller and the switch software.

Recommended Action Try reloading the switch. If this does not resolve the issue, this might be a hardware problem. Contact the Cisco technical support representative.

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.
