Avaya C360 - Spanning Tree Protocol CLI Commands

Avaya C360 Layer 2 Features
134 Installation and Configuration Guide Avaya C360 Multilayer Stackable Switches, version 4.5
● You must manually set the classification of uplink and backbone ports to "valuable" using
the set port classification CLI command.
● STP and Self Loop Discovery (SLD) are incompatible. However, If Spanning Tree is set to
rapid-spanning-tree version, there is no need to use the Self-loop-discovery feature; the
RSTP algorithm avoids loops generated by the IBM token ring cabling.
● The 802.1w standard defines differently the default path cost for a port compared to STP
(802.1d). In order to avoid network topology change when migrating to RSTP, the STP
path cost is preserved when changing the spanning tree version to RSTP. You can use the
default RSTP port cost by using the CLI command set port spantree cost auto.
Spanning Tree Protocol CLI Commands
The following table contains a list of CLI commands for the Spanning Tree feature. The rules of
syntax and output examples are all set out in detail in the Reference Guide for the Avaya C360
