This is performed by the STP subsystem at system initialization because the maximum number of ports on a particular platform does not change. The first [dec] is the number of bits for the port number, and the second and third [dec] describe the valid range.

Response 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 , see the “Error Message Traceback Reports” section on page .9

SPANTREE-3-PORT_SELF_LOOPED: [chars] disabled.- received BPDU src mac [enet] same as that of interface.

Explanation This message means that a BPDU was received on the listed interface with a source MAC address that matches the one assigned to the listed interface. This means that a port might be looped back to itself, possibly because of an installed diagnostic cable. The interface will be administratively shut down. [chars] is the interface that received the BPDU, and [enet] is the source MAC address.

Response Check the interface configuration and any cable connected to the interface. When the problem is resolved, re-enable the interface by entering the no shutdown interface configuration command.

SPANTREE-4-PORT_NOT_FORWARDING: [chars] [chars] [chars]

Explanation This message means that the port is not forwarding packets or is not in a forwarding state. The first [chars] is the alarm ASSERT or CLEAR action. The second [chars] is the user-configured alarm for this fault condition. The third [chars] is the interface.

Response 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 , see the “Error Message Traceback Reports” section on page .9

Note: This message applies only to the Catalyst 2955 switch.

SPANTREE-5-EXTENDED_SYSID: Extended SysId [chars] for type [chars].

Explanation This message means that the extended system ID feature is either enabled or disabled for the given type of spanning tree. If enabled, the spanning-tree instance identifier is stored in the lower portion of the bridge ID priority field and limits the allowed values for the bridge priority from 0 to 61440, in increments of 4096. If disabled, the bridge ID priority field consists only of the configured priority, but some spanning-tree features might not be available on a given platform (for example, support for 4096 VLANs). On some platforms, the extended system ID feature might be mandatory. The first [chars] is the extended system ID state (enable or disable), and the second [chars] is the spanning-tree instance.

Response No action is required.

Intelligent Gigabit Ethernet Switch Module specifications

Cisco Systems is a leader in networking technology, and their Intelligent Gigabit Ethernet Switch Module exemplifies the innovations the company brings to the realm of networking. Designed for flexibility, performance, and scalability, the switch module is tailored for enterprise environments that require robust and reliable network infrastructure.

One of the key features of the Intelligent Gigabit Ethernet Switch Module is its support for high-speed data transfer. With Gigabit Ethernet capabilities, it enables fast and efficient communication between devices, reducing latency and increasing productivity. This high-speed connectivity supports various applications, including video streaming, VoIP, and large file transfers.

Another major characteristic of the module is its versatility. The switch module is compatible with a range of Cisco platforms, allowing users to easily integrate it into their existing network setups. This compatibility means organizations can expand their network capabilities without needing to overhaul their entire infrastructure.

Security is another prominent feature of the Intelligent Gigabit Ethernet Switch Module. It incorporates advanced security protocols, ensuring that sensitive data remains protected as it traverses the network. Features like port security, access control lists (ACLs), and network segmentation help mitigate potential risks and safeguard against unauthorized access.

The module also integrates advanced traffic management technologies. Quality of Service (QoS) features allow administrators to prioritize critical traffic, ensuring that time-sensitive applications receive the necessary bandwidth. Moreover, Layer 2 and Layer 3 capabilities enable efficient routing and switching of data, further enhancing network performance.

Energy efficiency is a hallmark of the Intelligent Gigabit Ethernet Switch Module as well. Cisco has designed the module with environmentally friendly technologies that reduce power consumption, contributing to lower operational costs and a reduced carbon footprint.

In addition, the switch module supports automation and programmability features such as Cisco’s DNA Center, which provides a centralized management platform for monitoring and controlling network activity. This capability allows for easier deployment of policies, enhancing operational efficiency.

Overall, the Cisco Systems Intelligent Gigabit Ethernet Switch Module is a powerful networking solution, combining high-speed performance, advanced security, versatile integration, and efficient management to meet the growing demands of modern enterprise networks. As organizations continue to evolve, this switch module stands out as a reliable choice for companies seeking to optimize their network infrastructure for future challenges.
