Hi guys,
i need your help here. I need to setup this switch for a friend of mine in this particular scenario :
Firewall with 2 LAN (LAN1 192.168.10.x 255.255.255.0 and LAN2 192.168.20.x 255.255.255.0) and DHCP is enable on both LAN.
The 2 LAN are separated and devices in LAN 1 cannot see devices in LAN2 and vice versa.

I "just" need, if possible, to dedicate port switch from 1 to 24 for the LAN1 and from port 25 to 48 for the LAN2.
I think this switch can do more than that but i just need this so i don't have to use 2 switches.
Is this possible? and if yes could someone please tell me how ? I'm starting from a fresh setup using consolle cable to setup the switch.

Thanks
Mattia

So... You want this Quanta to be a router? Or do you have a firewall and just need to seperate the VLANs?

First of all, for routing functionality you'll need routing firmware (5.13.12.14).
Also, in your scenario there's no uplink to internet...
I have my LB4M set up as a switch, so you'll have to refer to the manual for DHCP configuration. But the rest should be something like this:

vlan database
vlan 10,20
vlan name 10 "LAN1_192.168.10.0_24"
vlan name 20 "LAN2_192.168.20.0_24"
exit
configure
ip access-list LAN1-ISOLATE
permit ip 192.168.10.0 0.0.0.255 192.168.10.1 0.0.0.0
deny ip any any
exit
ip access-list LAN2-ISOLATE
permit ip 192.168.20.0 0.0.0.255 192.168.20.1 0.0.0.0
deny ip any any
exit
interface 0/1-0/48
storm-control broadcast level 0.5
storm-control multicast level 0.5
load-interval 30
spanning-tree bpdufilter
mtu 9216
no shutdown
exit
interface 0/1-0/24
description "LAN1_192.168.10.0_24"
vlan pvid 10
vlan participation include 10
exit
interface 0/25-0/48
description "LAN2_192.168.20.0_24"
vlan pvid 20
vlan participation include 20
exit
interface vlan 10
ip address 192.168.10.1 255.255.255.0
ip access-group LAN1-ISOLATE in
no shutdown
exit
interface vlan 20
ip address 192.168.20.1 255.255.255.0
ip access-group LAN2-ISOLATE in
no shutdown
exit
ip dhcp pool "LAN1"
lease 0 4 0
dns-server 1.1.1.1
default-router 192.168.10.1
network 192.168.10.0 255.255.255.0
domain-name 1.local.net
exit
ip dhcp pool "LAN2"
lease 0 4 0
dns-server 1.1.1.1
default-router 192.168.20.1
network 192.168.20.0 255.255.255.0
domain-name 2.local.net
exit
service dhcp
exit

I have an issue on my LB4M. I'm trying to set up VLANs for my Unifi APs to give each SSID a different VLAN. I warn you, I'm new to vlans, so assume nothing.

My network configuration is: ESXi server (via 2x mellanox cards to 10GB dac cables) to LB4M on a port-channel with ports 0/49 and 0/50 (to form 3/1). My ESXi is running ClearOS and serving data via the vmx0 10gb virtual port.

My issue is I've configured vlans 10,20,30,40 on the ClearOS server and set up port 3/1 on the Quanta with tagging vlans 10,20,30,40. I have tagging out to the ports with the unifi APs, and the APs set with tagging each SSID. The issue is, I can't get anything to work, not even a little.

It's possible I've done this completely wrong, or it's possible I'm one step away from a sound set up. I'd be happy for advice.

My first thought is, how is your esxi vlan setup configured?

Wow. Yes, I have nothing for ESXi. Can you point me to setting up a trunk on ESXi? I've googled and am having trouble finding something that fits. I'm on ESXi 6.0 if that matters.

EDIT:

I set the ESXi trunk and all is well. Thanks

Hi!

After 3years of service - today suddenly the LB4M stopped processing the VLANS - you cannot connect to another switch using TRUNK link - the only working thing is using only one vlan on the ports ~ access ports - nothing more. The first sympthon was loosing the "mgmt_vlan" address - cannot ping or access via ssh.

Does anybody seen this?
