SG500X-48P POE

William Mayoral

Hi,

I am working with a cisco switch SG500X-48P POE, It needs to be use as inter-vlan. but every time that I create a vlan and try to assign an ip address to it. The http and telnet conctivity is lost. I have wait for a long time but the access to it never comes back.

Only way I can get access again is doing factory reset.

Hello William,

       Sorry the switch is not performing as expected.  What I think is happening is this.  With the device in factory default mode, VLAN 1 IP address 192.168.1.254 is self assigned if no DHCP server is present.  If you look at that IPV4 interface, the address is considered dynamic.  If you do not make this address static, and assign another VLAN with a static address, this static address will become the address of the switch.  And since there are no ports in this VLAN, we basically get locked out of the switch.

     To resolve this, it can be done 2 ways.  One is to create this second VLAN with an IP address assigned to it, and then assign one of the ports on the switch to be an access port in that VLAN.  Once the device reboots, if you assign you PC an address in that second VLANs network, and connect to that port that is the access port for that VLAN, you should be able to connect to that second VLAN IP address to manage the switch.    Second way, and probably the preferred way would be to go to Administration>Management Interface>Management Interface.  You will see that VLAN1 address 192.168.1.254 dynamic.  Change this to static and change the address if needed, save and copy run to startup config, you will be able to access the device from any port that has untagged VLAN1 from a PC.  Then you can configure your VLANs as needed and will not get locked out.  Hope this helps William.

I agree with that possibility.  I also suggest you upgrade to current release firmware and I think you need to put the switch into router mode to do inter-vlan routing: set system mode router
