Protecting the user

Use the following configuration for edge switches 2 and 3 (AT-8648 switches in this example):

ena stp=default

set stp=default mode=rapid

create vlan="voice" vid=101 private

add vlan=101 port=49-50 uplink frame=tagged add vlan=101 port=1-48 frame=tagged create vlan="video" vid=102 private

add vlan=102 port=49-50 uplink frame=tagged add vlan=102 port=1-48 frame=tagged create vlan="data" vid=103 private

add vlan=103 port=49-50 uplink frame=tagged add vlan=103 port=1-48 frame=tagged create vlan="management" vid=104 private add vlan=104 port=49-50 uplink frame=tagged add vlan=104 port=1-48 frame=tagged

#Give the management VLAN an appropriate IP address enable ip

add ip int=vlan104 ip=<address-in-192.168.4.0-subnet>

Use the following configuration for the access router (a Rapier 24i switch in this example):

delete lacp port=3-24 enable lacp

create vlan="voice" vid=101 create vlan="video" vid=102 create vlan="data" vid=103 create vlan="management" vid=104

add vlan=101 port=1-2 frame=tagged add vlan=102 port=1-2 frame=tagged add vlan=103 port=1-2 frame=tagged add vlan=104 port=1-2 frame=tagged

enable
