STP is enabled on Catalyst 1900 series switches by default. Sets the trunk group to which the port is assigned.The purpose of the Spanning Tree Protocol (STP) is to prevent loops on a switched or bridged network. Sets the port to ignore superior BPDUs to prevent the switch from becoming the Root Port. A BPDU guard also assists when a port inadvertently goes into a forwarding state. This configuration is not recommended for ports which connect to infrastructure devices. When set, the port directly goes into forwarding state. Recommended ports for BPDU filter: Ports or trunks connected to client devices. A port with the BPDU filter enabled ignores incoming BPDU packets and stays locked in the STP forwarding state. The feature can be used to exclude specific ports from becoming part of STP operations. traps.Įnables control of STP participation for each port. It is used mostly in network management systems to monitor network-attached devices for conditions that warrant administrative attention. Devices that typically support SNMP include routers, switches, servers, workstations, printers, modem racks, and more. SNMP is a TCP/IP standard protocol for managing devices on IP networks. If STP BPDU packets are received on a protected port, the port is disabled and the network manager is alerted via SNMP Simple Network Management Protocol. In a typical implementation, BPDU protection is applied to the edge ports and access ports connected to end-user devices that do not run STP. A BPDU is a data message transmitted across a local area network to detect loops in network topologies. This is not a recommended process as it randomizes the selection of the root bridge.Ī security feature used to protect the active STP topology by preventing spoofed BPDU Bridge Protocol Data Unit.

So the switch with the lowest MAC automatically gets selected as a root bridge. All AOS-Switches have a default STP priority of 8. A MAC address is a unique identifier assigned to network interfaces for communications on a network. When the switches in a network select their root bridge, two parameters are considered, the STP priority and the MAC Media Access Control. A higher numerical value means a lower priority thus, the highest priority is 0. The switch with the lowest value has the highest priority and is the root bridge. Table 1: Viewing or Configuring Port and Trunk SettingsĪ number used to identify the root bridge in an STP instance. Configure the following MSTP parameters for ports or trunks of individual switches:.To configure MSTP parameters for trunks, select the trunk group row(s) in Trunk Group Settings, click Edit.To configure MSTP parameters for ports, select the port row(s) in Port Settings, click Edit.If you have a trunk group configured for the switches in the group, MSTP is enabled at the trunk level. In computer networking, a single Layer 2 network may be partitioned to create multiple distinct broadcast domains, which are mutually isolated so that packets can only pass between them through one or more routers such a domain is referred to as a Virtual Local Area Network, Virtual LAN, or VLAN. MSTP will be enabled for all VLANs Virtual Local Area Network. if you want to avoid bridge loops between network nodes and to maintain a single active path between the network nodes. MSTP configures a separate Spanning Tree for each VLAN group and blocks all but one of the possible alternate paths within each spanning tree.

STP is a network protocol that builds a logical loop-free topology for Ethernet networks.) eliminates Layer 2 loops in networks, by selectively blocking some ports and allowing other ports to forward traffic, based on global (bridge) and local (port) parameters you can configure. The Spanning Tree Protocol ( STP Spanning Tree Protocol. This is a beta feature and not recommended for a production environment.
