We recently bought a few Small Business switches. 1x SG500-52, 2x SF500-24P and 10x SG300-10P. All switches have the latest firmware installed and are set to Layer 3. On all switches we created VLAN's.
The SG500-52 will be in our main location. It will be connected through fiber with the 2 SF500-24P switches. For testing everything, I have setup everything in a room. But I run into some problems. First I will tell about the config of the SG500-52, SF500-24P and a SG300-10P
Configuration SG500-52 : Prt 25,49,50,51 and 52 are configured as trunk ports. All other ports are configured as access ports.
Prt 9 has a fiber connection with Prt 26 of the SF500-24P. VLAN 1 has an IP address assigned.
Hope this helps with answering my questions.
Problem 1 : When I connect my pc to interface 2 of the SG500-52, I don't get an IP address from DHCP. It worked yesterday, before I changed prt 25, from access to trunk port. This had to be done to get the voip working.
Problem 2 : When I connect a IP-phone to interface 2 of the SF500-24P, the phone works fine, but when I connect the same phone to interface 2 of the SG300-10P, the phone keeps restarting after the message http 1 200.
I hope someone can explain why I have these 2 problems and we can continue with our test. Thanks in advance.
When I configure the port for VLAN 2 as untagged on VLAN 20, my phones keep working. Port for VLAN 2 also needs to be configured as a trunk port on every switch, not only the main switch. When I do this, my VLAN 20 ports work also and get an DHCP address from the server without any problem.
Only problem now is, when I power down my switch and power it up again, my configuration is messed up. Ports are not tagged anymore or suddenly become untagged. And I am shure I saved my running config to startup config.
