Its really my first foray into a Cisco SMB device - have been trying to configure the SG300 10P for a few days now but to no avail. I have also upgraded to latest firmware 1.3.5.58 and now downgraded back to 1.3.0.62 and the problem resides.
I am simply trying to create vlan and assign an IP to it (I am in L3 mode) - however each time I go to apply the IP - I lose connection and then I have to unplug the device again to connect back. For example if I try to implement the below - courtesy of Tom Watts at the point where I am creating vlan 200 and assigning the Ip address once I press enter - it will lose connection. The same happens within the gui. Any ideas where I am going wrong.
config t
vlan database
vlan 200
exit
interface vlan 1
ip address 192.168.100.137 255.255.255.0
no ip address dhcp
exit
interface vlan 200
ip address 192.168.99.1 255.255.255.0
exit
ip dhcp server
ip dhcp pool network test
address low 192.168.99.1 high 192.168.99.254 255.255.255.0
default-router 192.168.99.1
dns-server 8.8.8.8
Also separately I can't get the DHCP server to issue any Ip addresses to clients so I am having manually assign addresses on client devices.

Hi Abdul,
If the switch is factory default try to do this
config t
int vlan 1
ip address 192.168.100.137 /24
----> Reconnect to the switch on the management IP
config t
vlan database 200
ip address 192.168.99.1 /24

Hi Tom
Thanks for the response - I think the issue with the loss of connection has been with the fact that the static ip of the default vlan 1 has not been set to static.
however still cant get dhcp server to work. The idea is that Vlan 10 issues ip address from a pool to devices (laptops etc).
My config as follows
ip dhcp server
ip dhcp pool network office
address low 172.19.1.1 high 172.19.1.253
default-router 172.19.1.254
dns-server 8.8.8.8
interface vlan 1
ip address 172.19.0.240 255.255.254.0
no ip address dhcp
interface vlan 10
ip address 172.19.1.254 255.255.255.0

Hi Abdul, your config looks right
Here is my config
ip dhcp server
ip dhcp pool network test
address low 192.168.2.2 high 192.168.2.254 255.255.255.0
lease infinite
default-router 192.168.2.1
dns-server 8.8.8.8
So the only omission I see is if you made an access port for your VLAN.
config t
int gi05
switchport mode access
switchport access vlan 10
