the previous network engineer has configure the network and i am trying to understand the configuration
create vlan "data_managment"
configure vlan data_managment tag 1702
create vlan "KKK"
configure vlan KKK tag 771
create vlan "test"
configure vlan test tag 777
create vlan "voice"
configure vlan voice tag 10
configure vlan data_managment add ports 46-50 tagged
configure vlan KKK add ports 49-50 tagged
configure vlan test add ports 1-50 untagged
configure vlan voice add ports 1-50 tagged
configure vlan data_managment ipaddress 172.17.2.23 255.255.255.0
configure vlan test ipaddress 10.100.9.23 255.255.255.0
configure vlan KKK ipaddress 172.20.40.23 255.255.0.0
configure vlan voice ipaddress 18.104.22.168 255.255.0.0
ports 49 and 50 are connected to the core switch
i am new in extreme switch so i want to ask
first is it must to have ports untagged if they are connected to pc or telephone
second how does the switch distinguish the vlan suppose we connect a pc to port 1
how the switch will know its kkk or voice or test
if i connect a pc it will get ip 172.20.40.40/24 and if i connect a telephone it will get 22.214.171.124/16
