Changing the switch working mode will *delete* the startup configuration file
and reset the device right after that. It is highly recommended that you will
backup it before changing the mode, continue ? (Y/N)[N] Y

My network I want VLAN1 on is 192.168.10.0/24 with route out 192.168.10.1, DNS of 192.168.10.1, and I will use IP 192.168.10.254 for the switch IP address.

switch742bd5# conf t
switch742bd5(config)#interface vlan 1
switch742bd5(config-if)#ip address 192.168.10.254 /24
switch742bd5(config-if)#exit
switch742bd5(config)#ip default-gateway 192.168.10.1
switch742bd5(config)#ip name-server 192.168.10.1
switch742bd5(config)#exit
switch742bd5#write mem
Overwrite file [startup-config].... (Y/N)[N] ?Y

21-Dec-2015 16:57:36 %COPY-N-TRAP: The copy operation was completed successfully
Copy succeeded


Now reboot the switch and make sure the changes stuck.

switch742bd5#reload
This command will reset the whole system and disconnect your current session. Do you want to continue ? (Y/N)[N] Y
Shutting down ...

From Windows desktop I pinged the address 192.168.10.254, after the switch has rebooted.

At this point I updated firmware to 1.4.2.4
I downloaded this on PC from the Cisco website and saved to my desktop.
I then logged into the web ui using username and password set prior.
Navigated to Administration -> File Management -> Upgrade/Backup Firmware/Language.
I selected Transfer Method: via HTTP/HTTPS, Save Action: Upgrade, File Type: Firmware Image.
File Name: (Browse to my desktop) sx300_fw-1424.ros
Clicked on Apply.
When finished click Done.
Now set the new firmware active under Administration -> File Management -> Active Image, Select image in drop down, and click Apply.
Now save changes under Administration -> File Management -> Copy/Save Configuration, using Source File Name: Running configuration Destination File Name: Startup configuration.
Click Apply.


Back to your Putty serial connection. Login if not already.

After the restart verify some of your info so far.

Now I setup a user name admin, with password password, with full rights, and will use this to SSH into the switch in the future.

switch742bd5#conf t
switch742bd5(config)#username admin password password privilege 15
switch742bd5(config)#exit
switch742bd5#write mem
Overwrite file [startup-config].... (Y/N)[N] ?Y
21-Dec-2015 16:52:11 %COPY-I-FILECPY: Files Copy - source URL running-config destination URL flash://startup-config
21-Dec-2015 16:52:14 %COPY-N-TRAP: The copy operation was completed successfully
Copy succeeded
switch742bd5#

Now turn on the SSH server

switch742bd5#conf t
switch742bd5(config)#ip ssh server
switch742bd5(config)#exit
switch742bd5#write mem
Overwrite file [startup-config].... (Y/N)[N] ?Y
Copy succeeded
switch742bd5#
switch742bd5#

You should now be able to SSH into the switch with IP 192.168.10.254 using the username admin with password password.

After you have SSH into the switch lets set a hostname. Since this is a SG300-10, it is located on a street called Jasper, and it is my first one of these..

switch742bd5#conf t
switch742bd5(config)#hostname SG300-10-JASPER1
SG300-10-JASPER1(config)#exit
SG300-10-JASPER1#write mem
Overwrite file [startup-config].... (Y/N)[N] ?Y
Copy succeeded
SG300-10-JASPER1#
SG300-10-JASPER1#

You can also turn off password aging now if you like.

SG300-10-JASPER1(config)#passwords aging 0SG300-10-JASPER1(config)#exit
SG300-10-JASPER1#show passwords configuration

Passwords aging is disabled.
Passwords complexity is enabled with the following attributes:
Minimal length: 8 characters
Minimal classes: 3
New password must be different than the current: Enabled
Maximum consecutive same characters: 3
New password must be different than the user name: Enabled
New password must be different than the manufacturer name: Enabled
switch742bd5#write mem
Overwrite file [startup-config].... (Y/N)[N] ?Y
Copy succeeded
SG300-10-JASPER1#
SG300-10-JASPER1#


If you want Jumbo frame support on your network then:

SG300-10-JASPER1(config)#port jumbo-frame 
SG300-10-JASPER1(config)#exitSG300-10-JASPER1#write mem
Overwrite file [startup-config].... (Y/N)[N] ?Y
Copy succeededSG300-10-JASPER1#SG300-10-JASPER1#

That's it for now. In a later post I will cover setting up VLANs. Enjoy!
