Enterasys STP Spanning Tree Protocol Configuration

In our previous article titled Spanning Tree Protocol Usage and Configuration – STP, we gave information about Spanning Tree Protocol and Network Loop. As the second stage, we will move on to the configuration application for Enterasys Network Switches.

First of all, we will make spanning tree configuration on 800 Series Enterasys Switches.

Spaning Tree for Enterasys 800 Series

STP service comes with factory default enable. The commands for enabling and disabling are as follows;

enable stp
disable stp

Information about the running Enterasys Spanning Tree Protocol can be accessed by typing the -show command.

show stp

#Command: show stp

STP Bridge Global Settings
---------------------------
STP Status : Enabled
STP Version : RSTP
Max Age : 25
Hello Time : 2
Forward Delay : 15
Max Hops : 20
TX Hold Count : 6
Forwarding BPDU : Disabled
NNI BPDU Address : dot1d

It can be determined separately which VLAN ids in the network will be applied Spanning Tree Protocol and which ones will not be applied. In this example, VLAN1, VLAN2, VLAN3 were added to instance-2 protocol.

config stp instance_id 2 add_vlan 1-3

#Command: config stp instance_id 2 add_vlan 1-3
Success.

Similarly, if we want to remove VLAN-2 added to instance-2 protocol

config stp instance_id 2 remove_vlan 2

#Command: config stp instance_id 2 remove_vlan 2
Success.

Type the following command to completely remove the existing instance definition.

delete stp instance_id 2

#Command: delete stp instance_id 2
Success.

Spanning Tree Protocol can be configured in two different ways according to its algorithms. M-STP and R-STP

config stp version rstp

Extreme C-S Serisi Spanning Tree Configuration

Let’s briefly write the commands for Extreme C and S series Enterasys spanning tree.

show spantree version

set spantree version rstp   (rstp, stp veya mstp olarak yazılabilir)

set spantree priority 0     (Switchi root (kök) switch yapar)

set spantree portadmin ge.1.21-22 disable

In which ports it will be disable, stp may not be done for the -uplink interface.
