Port Fast Forwarding

BLADEOS 6.5.2 Application Guide

Fast Uplink Configuration Guidelines

When you enable Fast Uplink Convergence, BLADEOS automatically makes the following configuration changes:

The bridge priority is set to 65535 so that it does not become the root switch.

The cost of all ports is increased by 3000, across all VLANs and STGs. This ensures that traffic never flows through the G8124 to get to another switch unless there is no other path.

These changes are reversed if the feature is disabled.

Configuring Fast Uplink Convergence

Use the following command to enable Fast Uplink Convergence on ports.

RS G8124(config)# spanning-tree uplinkfast

Port Fast Forwarding permits a port in STP/PVST+ mode to bypass the Listening and Learning states and enter directly into the Forwarding state. While in the Forwarding state, the port listens to the BPDUs to learn if there is a loop and, if dictated by normal STG behavior (following priorities, etc.), the port transitions into the Blocking state. This feature permits the G8124 to interoperate well within Rapid Spanning Tree (RSTP) networks.

Use the following commands to configure Port Fast Forwarding for a specific STG on a selected port:

RS G8124(config)# interface port <port number>

RS G8124(config-if)# [no] spanning-tree stp <STG number> fastforward

RS G8124(config-if)# exit
