3 VLANs - How to connect a switch to the core properly
Hi there. We have a core with 2 VLANs configured. We also have a separate switch with 3 VLANs configured that we'd like to connect to a port on the core.
core VLANs = 1-Default 2-Voice 200-Barco
new switch VLANS = 1-Default 2-Voice 3-VoiceNY
All ports are tagged on the new switch like so...
vlan 1
name "Default"
no untagged 1-30
untagged 31-48
ip address 192.168.2.20 255.255.252.0
exit
vlan 2
name "Voice"
untagged 1-20
ip address 192.168.3.6 255.255.255.0
exit
vlan 3
name "VoiceNY"
untagged 21-30
ip address 192.168.4.7 255.255.255.0
exit
Do I need to untag the port on the new switch that we plan to use for the uplink/downlink from the core to the switch? And do the same on the core, remove the tag the port connecting to the new switch?
right now when I plug it in, the port we plug in immediately disables itself on the core.
thanks

Re: 3 VLANs - How to connect a switch to the core properly
We would need the old switch config to see what subnets are on those VLANs on the old switch.
Are you intending on both switches routing within their subnets?
