Issue with connection to remaining internal network
I purchased this switch a couple of days ago to give me more ports on a part of my network. I'm having a challenge getting it to connect properly.
Let me describe the situation. Here is my network:
- Starlink is my ISP. The router is in bypass mode.
- My router is Araknis AN-220-RT. I am running only the default VLAN, no internal sub networks.
- The router is some distance from my utility room, where the bulk of my network gear is housed. The ethernet line from the router is fed into a 48-port TRENDnet switch, not managed. I have a bunch of other networking gear in the house. This is not where I installed the TL-SG1016PE. I'm having no issues with the network in the house.
- A line from the TRENDnet switch is run to an outbuilding on the property. Here is where I installed the TL-SG-1016PE.
- Prior to the upgrade, I had two switches in this location: a Hikvision DS-3E0510P-E (8 ports with PoE) and a TRENDnet 5-port unmanaged switch daisychained to it.
- The Hikvision switch fed some PoE security cameras, a TP Link WAP (EAP245), and some TVs.
- I wanted to add more ports in this area so I bought the TP Link managed switch with PoE.
When I replaced the Hikvision and TRENDnet switches with the TP Link, I was unable to establish an internet connection in that location. The link light for downstream devices were blinking and the devices that needed PoE were getting it, but the link light on the main line back to the house was dead. I found that if I connected that line to the Hikvision switch first and then daisychained the TP Link switch off of it, all was well. This is not an ideal hardware situation for me so I would like to get the TP Link switch working solo. I did a bunch of troubleshooting but I'm out of ideas. Would be great if someone here could point me in the right direction.
Here is a summary of the settings in the TL-SG1016PE:
- DHCP enabled
- IGMP snooping disabled
- no LAG groups
- no port mirroring
- Loop prevention disabled
- MTU and Port-based VLAN disabled
- 802.1Q VLAN enabled, all ports untagged
Here are some of the settings in the Araknis router:
- VLAN page: only the default VLAN, device management enabled, LAN untagged
- no VPN tunnels in use
- IP Mode page: dual-stack IP disabled, IPv6 to IPv4 tunnel disabled
- Local DNS database page: domain name router90760d.com, no local DNS hosts
Any ideas for me? Thanks in advance.
Hi @JeremyM
Thanks for posting in our business forum.
No internet, huh? Strange. So, can you make sure that the uplink cable is working ok?
What about you connect a PC to this uplink cable? Do you get an IP address and what about the ping result? About the ping, read this.
If you have an IP and ping to the gateway is okay, what would be the result of trace route on your PC?
@Clive_A Just for fun, I connected the TP Link switch directly to the Araknis router and got this result:
MacBook-Air-3:downloads jeremy$ ping 192.168.0.1
PING 192.168.0.1 (192.168.0.1): 56 data bytes
64 bytes from 192.168.0.1: icmp_seq=0 ttl=64 time=1.392 ms
64 bytes from 192.168.0.1: icmp_seq=1 ttl=64 time=1.047 ms
Then I plugged the TP Link switch into the TRENDnet switch in the house. This is the same switch into which the upstream side of the trunk line is connected. I got this result:
MacBook-Air-3:downloads jeremy$ ping 192.168.0.1
PING 192.168.0.1 (192.168.0.1): 56 data bytes
64 bytes from 192.168.0.1: icmp_seq=0 ttl=64 time=0.607 ms
64 bytes from 192.168.0.1: icmp_seq=1 ttl=64 time=0.643 ms
OK, so all of this indicates that the problem occurs only when I plug the TP Link switch into the downstream side of the trunk line. What does this mean? Could it be the way the trunk line is terminated?
Here are photos of the upstream side:
...and the downstream side:
@Clive_A I read the article. Thanks for pointing me to the resource. I don't see what I am doing wrong with the VLAN configuration. For the initial setup of the switch, I am mirroring the router and using only the default VLAN with all network traffic being untagged.
Here is the screenshot of the VLAN config page in the router:
and here is the switch:
All other switches in the network are unmanaged, dumb ones. They don't have the ability to configure VLAN traffic.
What am I missing?
