SPANTREE-7-BLOCK-PORT-TYPE: Blocking [chars] on [chars]. Inconsistent port type.

Explanation This message means that the listed interface is being held in the spanning-tree blocking state until the port-type inconsistency is resolved. The first [chars] is the interface, and the second [chars] is the spanning-tree instance.

Response Verify that the configuration and operational states of the listed interface and those of the interface to which it is connected are in the same mode (access or trunk). If the mode is trunk, verify that both interfaces have the same encapsulation (ISL or 802.1Q). When these parameters are consistent, spanning tree automatically unblocks the interface.

SPANTREE-7-RECV-1Q-NON-TRUNK: Received 802.1Q BPDU on non trunk [chars] [chars].

Explanation This message means that an SSTP bridge protocol data units (BPDU) was received on the listed interface, which is not an operational trunking interface. The first [chars] is the port name, and the second [chars] is the VLAN name.

Response Verify that the configuration and operational state of the listed interface and that of the interface to which it is connected are in the same mode (access or trunk). If the mode is trunk, verify that both interfaces have the same encapsulation (none, ISL, or 802.1Q). When these parameters are consistent, spanning tree automatically unblocks the interface.

SPANTREE_FAST-7-PORT_FWD_UPLINK: [chars] [chars] moved to Forwarding (UplinkFast).

Explanation This message means that the listed interface has been selected as the new root port for the listed spanning-tree instance.

Response No action is required.

SPANTREE_VLAN_SW-2-MAX_INSTANCE: Platform limit of [dec] STP instances exceeded. No instance created for

[chars] (port [chars]).

Explanation This message means that the number of currently active VLAN spanning-tree instances has reached a platform-specific limit. No additional VLAN instances will be created until the number of existing instances drops below the platform limit. The message shows the smallest VLAN number of those VLANs that are unable have STP instances created.

Response Reduce the number of currently active spanning-tree instances by either disabling some of the currently active spanning-tree instances or by deleting the VLANs associated with currently active spanning-tree instances. You need to manually enable the spanning trees that could not be created due to limited STP instances.

SPANTREE-4-PORT_NOT_FORWARDING: ASSERT MINOR [char] Port Not Forwarding.

Explanation This message means that the port is not forwarding packets; that is, it is not in a forwarding state. [char] is the port.

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

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.
