Enabling Spanning Tree Protocol on Aruba Switches in UI Groups

PortFast is usually configured on an edge port, which means the port should not receive any STP BPDUs. If the port receives any STP BPDU, it moves back to normal/regular mode and will participate in the listening and learning states. In most deployments, edge ports are access ports. Spanning-tree admin-edge-port 'BPDU Protect' feature will protect your ports i.e. Against rogue switches. 'Admin Edge' feature will save you 3 seconds when bringing a port online 'BPDU filter' is not recommended, because you might filter some BPDUs which you might need for detecting loops.

Default on ports. The port will look for BPDUs for 3 seconds; if there are none it begins forwarding packets and port is set as Edge, if there are BPDUs, it sets the port as non-Edge. As an admin, if you do not care about the 3 sec delay, auto-edge-port is an easy end recommended setup. For a manual setup of Edge ports, enable admin-edge-port on ports connected to end nodes. During spanning tree. These are normal log messages for a port bouncing on a HP Procurve/Aruba switch. The normal sequence of events for a port (connected to a non-STP edge host as most IP phones are) coming on-line and then off-line is: Port is Blocked by STP; Port is now on-line; Port is now off-line; The port enters STP blocked when it is first brought up.

This is a beta feature and not recommended for a production environment.

The Spanning Tree Protocol (STPSpanning Tree Protocol. 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.

For switches provisioned in UI groups, enable or disable STPSpanning Tree Protocol. STP is a network protocol that builds a logical loop-free topology for Ethernet networks. on the switch ports or trunks by using the UI menu options available under Wired Management.

STPSpanning Tree Protocol. STP is a network protocol that builds a logical loop-free topology for Ethernet networks. is always disabled by default on Aruba switches. To configure STPSpanning Tree Protocol. STP is a network protocol that builds a logical loop-free topology for Ethernet networks. for switches provisioned in the UI groups:

1. Click Wired Management.

2. From the group selector, select the UI group to which the switches are assigned.

3. Enable STPSpanning Tree Protocol. STP is a network protocol that builds a logical loop-free topology for Ethernet networks. if you want to avoid bridge loops between network nodes and to maintain a single active path between the network nodes. STPSpanning Tree Protocol. STP is a network protocol that builds a logical loop-free topology for Ethernet networks. will be enabled all VLANsVirtual Local Area Network. 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. assigned to switch ports. If you have a trunk group configured for the switches in the group, STPSpanning Tree Protocol. STP is a network protocol that builds a logical loop-free topology for Ethernet networks. is enabled at the trunk level.

4. Set the priority of the UI group. Refer to the following tables for configuring the STPSpanning Tree Protocol. STP is a network protocol that builds a logical loop-free topology for Ethernet networks. parameters for port or trunks of individual switches. To edit a port or a trunk, select the check-mark on the right-most column and then click Edit.

The switch with the lowest value has the highest priority and is the root bridge. A higher numerical value means a lower priority; thus, the highest priority is 0.

When the switches in a network select their root bridge, two parameters are considered, the STPSpanning Tree Protocol. STP is a network protocol that builds a logical loop-free topology for Ethernet networks. priority and the MACMedia Access Control. A MAC address is a unique identifier assigned to network interfaces for communications on a network. address of the switch. All Aruba switches have a default STPSpanning Tree Protocol. STP is a network protocol that builds a logical loop-free topology for Ethernet networks. priority of 8. So the switch with the lowest MACMedia Access Control. A MAC address is a unique identifier assigned to network interfaces for communications on a network. automatically gets selected as a root bridge. This is not a recommended process as it randomizes the selection of the root bridge.
