XS728T: Does separate 10Gb VLAN need own router?

I set up the XS728T for an office 3.5 years ago, with a 1Gb 192.168.1.x network recieving addresses via DHCP from their own internet provider router. 

A second, separate, 10.0.0.x 10Gb VLAN network with no internet access was set up for 4K video editing from a NAS/server. It worked amazingly well with speeds close to saturaitng the 10Gb line, when the NAS was empty. At 50% full, it still averaged 700MB/sec connections of multiple 4k streams to several clients


The XS728T had to be replaced via warranty(2nd time), and they moved offices last month. They now share a Router(192.168.1.1) doing DHCP(192.168.1.x), that I cannot access its configuration. No problem there for internet access, everythign works for the DHCP receiving ports. But, I cannot remember how I set up the 10Gbe VLA, network. I cannot remember if I had to use a separate router for the VLAN.

For testing purposes, I have a VLAN sub-network of a single Freenas server(10.0.0.2/24), the switch(10.0.0.1/24), and a single iMac client(10.0.0.3/24)

 

VLAN2:
1) via the VLAN Routing Wizard, with an IP address of 10.0.0.1/255.255.255.0.

2) two untagged ports (22 & 24) are members, for the NAS and client

3) ROUTING>VLAN>VLAN ROUTING shows VLAN2 configured with the MAC. IP address, and subnet mask.
4) ROUTING>ROUTING TABLE shows it properly configured for the 10.0.0.0 network

5) PORT CONFIGURATION shows both 22 & 24 "UP" and "10G Full Duplex"
6) PVID for port 22 & 24 is set to 2

 

FreeNAS/Server:
1) 10.0.0.2/255.255.255.0 
2) I can ping the switch at 10.0.0.1

root@freenas:~ # ping 10.0.0.1
PING 10.0.0.1 (10.0.0.1): 56 data bytes
64 bytes from 10.0.0.1: icmp_seq=0 ttl=64 time=1.051 ms
64 bytes from 10.0.0.1: icmp_seq=1 ttl=64 time=1.016 ms
64 bytes from 10.0.0.1: icmp_seq=2 ttl=64 time=0.988 ms
64 bytes from 10.0.0.1: icmp_seq=3 ttl=64 time=0.970 ms
64 bytes from 10.0.0.1: icmp_seq=4 ttl=64 time=1.001 ms
64 bytes from 10.0.0.1: icmp_seq=5 ttl=64 time=0.964 ms

 

3) However, pinging from the switch to the NAS returns this:
Reply From 10.0.0.2: icmp_seq = 1. time = 10 msec.
Reply From 10.0.0.2: icmp_seq = 2. time = 0 msec.
Reply From 10.0.0.2: icmp_seq = 3. time = 10 msec.
Reply From 10.0.0.2: icmp_seq = 4. time = 10 msec.
Reply From 10.0.0.2: icmp_seq = 5. time = 0 msec.
Reply From 10.0.0.2: icmp_seq = 6. time = 0 msec.
Reply From 10.0.0.2: icmp_seq = 7. time = 0 msec.
Reply From 10.0.0.2: icmp_seq = 8. time = 10 msec.
Reply From 10.0.0.2: icmp_seq = 9. time = 0 msec.
Reply From 10.0.0.2: icmp_seq = 10. time = 0 msec.
Tx = 10, Rx = 10 Min/Max/Avg RTT = 0/10/4 msec

 

iMac client conntects via a Sonnet Twin 10Gb Thunderbolt Adapter:
1) 10.0.0.3/255.255.255.0.

2) it requires a router address, so I listed the switch's 10.0.0.1
3) internal address is up and pingable via Terminal
4) cannot attempt external pings to this adrress, as it can't mount the NAS address via NFS

Do I need a seperate router for the 10.0.0.x network to allow these three to conenct properly? 
If not, what am I missng? This seems so simple

Re: XS728T: Does separate 10Gb VLAN need own router?

While XS728T is a L2+ switch, it does provide some basic IPv4 routing capabilities - so technically, configuring and enabling routing would be possible.

 

The question you should answer on your own: What is the point of VLAN-isolating this video edit subnet when on the other hand you think about NFS mounting the NAS or from the 192.168.1.0/24 or using that very same subnet as an intermediate network to reach the Internet? 

 

Don't be worried about the different ping results - this depends on the ping client in use, the one on these switches are very simple and don't allow to measure the ping reply times in a more granular way.

Problem solved. I took your advice and configured a 192.168.2.x sub-network for testing
