Step-by-Step
Procedure
To configure interfaces and MSTP on Switch 3:
1.
Configure the VLANs
voice-vlan
,
employee-vlan
,
guest-vlan
, and
camera-vlan
:
[edit vlans]
user@switch3#
set voice-vlan description “Voice VLAN”
user@switch3#
set voice-vlan vlan-id 10
user@switch3#
set employee-vlan description “Employee VLAN”
user@switch3#
set employee-vlan vlan-id 20
user@switch3#
set guest-vlan description “Guest VLAN”
user@switch3#
set guest-vlan vlan-id 30
user@switch3#
set camera-vlan description “Camera VLAN”
user@switch3#
set guest-vlan vlan-id 40
2.
Configure the VLANs on the interfaces, including support for the Ethernet Switching
protocol:
[edit interfaces]
user@switch3#
set ge-0/0/26 unit 0 family ethernet-switching vlan members [10
20 30 40]
user@switch3#
set ge-0/0/28 unit 0 family ethernet-switching vlan members [10
20 30 40]
user@switch3#
set ge-0/0/24 unit 0 family ethernet-switching vlan members [10
20 30 40]
3.
Configure the port mode for the interfaces:
[edit interfaces]
user@switch3#
set ge-0/0/26 unit 0 family ethernet-switching port-mode trunk
user@switch3#
set ge-0/0/28 unit 0 family ethernet-switching port-mode trunk
user@switch3#
set ge-0/0/24 unit 0 family ethernet-switching port-mode trunk
4.
Configure MSTP on the switch, including the two MSTIs:
[edit protocols]
user@switch3#
mstp configuration-name region1
user@switch3#
mstp bridge-priority 8k
user@switch3#
mstp interface ge-0/0/26.0 cost 1000
user@switch3#
mstp interface ge-0/0/26.0 mode point-to-point
user@switch3#
mstp interface ge-0/0/28.0 cost 1000
user@switch3#
mstp interface ge-0/0/28.0 mode point-to-point
user@switch3#
mstp interface ge-0/0/24.0 cost 1000
user@switch3#
mstp interface ge-0/0/24.0 mode point-to-point
user@switch3#
mstp interface all cost 1000
user@switch3#
mstp msti 1 bridge-priority 4k
user@switch3#
mstp msti 1 vlan [10 20]
user@switch3#
mstp msti 2 bridge-priority 16k
user@switch3#
mstp msti 2 vlan [30 40]
Results
Check the results of the configuration:
user@switch3> show configuration
interfaces {
ge-0/0/26 {
unit 0 {
