Switch inaccessable when I create an IP interface on SG500-28P

[Boudewijn Plomp]

Hi,

I have a brand new SG500-28P sitting on my desk. I am having a very weird problem. I hope someone can advice me.

The swtich is configured and going to operate in L3 mode. All ports are still assigned to the default VLAN ID 1. I have created several new VLAN's. Once I configure and aplly an IP Interface to a certain VLAN the swtich becomes inaccessable right away. I am pretty sure I am not pulling my own VLAN under my connection. Every port is inaccessable. I have to pull the power plug and restart the swtich with its saved configuration. Even when I add another IP interface to the default VLAN 1, same issue. I have tried lot's of things, but can't get it to work properly. I have just upgraded to the latest firmware.

I have configured dozens of SG300 swtiches which is very easy. This one does not work with me.

Any suggestions?

Hi, you need to assign a static IP to vlan 1 first.

config t

int vlan 1

ip address 192.168.1.254 /24

int vlan 2

ip address 192.168.2.254 /24

etc. This will resolve the problem.

I just noticed that. VLAN ID already has the default IP interface 192.168.1.254. But I noticed that when you add another IP interface the IP interface for VLAN 1 is removed. I find that a bit strange.

But this will do. Thank you.
