Inter VLAN routing on cisco SG300

[lantech.solution]

Hi,

I have referred lots of details on internet for simple config of my SG300-28 switch i.e. "Inter VLAN routing on cisco SG300", hava found lots of solutions and many of them are so simple on paper but when I try them I failed. Please help me find where I am making a mist

	Creat two VLAN 1)192.168.1.254 and 2) 192.168.2.254
REQUIREMENT
VLAN 1 (default VLAN)
IP	192.168.1.254 - default
Name	VLAN 1 (default VLAN)
Client	192.168.1.100
Client gateway	192.168.1.254
VLAN 2 (user created)
IP	192.168.2.254
Name	VLAN 2 (TEST)
Client	192.168.2.100
Client gateway	192.168.2.254
Needs intervlan routing so that I can get ping reply from 192.168.1.100 when try to ping from 192.168.2.100
similarly from 192.168.2.100 when I try to ping from 192.168.1.100
STEPS I AM FOLLOWING
Unbox the switch and login to it using browser 192.1681.254 (google chrome)
Change the password as asked when login frirst time
Change the switch mode from L2 to L3
On saving switch reboots and after reboot I can see the switch mode is L3 nos
I go to create VLAN
Now I can see VLAN 1 - default with IP address 192.168.1.254
I add new VLAN i.e VLAN 2, name - TEST
On checking the port types / assignement I can see all ports are untagged and trunk for VLAN -1
I go to VLAN 2 and I make port 2 untagged member of VLAN 2 and the same is traunk type by default
Now I change Port 1 and 2 both as Access by editing them
Now finally switch port 1 is an untanned , access port of VLAN -1 where I am connecting my PC with IP 192.168.1.100
Switch port 2 is an untanned , access port of VLAN -2 where I am connecting my PC with IP 192.168.2.100
Now I go to IP interface and select VLAN 2 to give an IP address to it i.e 192.168.2.254 but when I selecet "apply" immediately switch hangs and I cant do any thing
I have to reboot the switch with power off / on
Same things repeats every time
Please help

Hello,

Thank you for contacting Cisco support.

Apologies for the inconveniences you are experiencing. Looking at your results, please assign the ip address of vlan 1 (192.168.1.254) statically to the switch before assigning the ip address (192.168.2.254) to the Vlan 2, this is because the switch takes the first statically assigned ip address and uses it on the default vlan (vlan 1). This why you lose access to the switch.

Please contact our SBSC phone line at 1866-606-1866 for immediate assistance.

Have a great day!

Hi,

Thanks for your reply. It worked. I change the default IP and then created two VLANs and could see routing happening. Now I am planning to implement the solution in a real operational network and have following questions in my mind. Request you to please help.

1) All the three switches have same IP address, do I need to worry about it when I put all them to gather in my network. My network is flat and may or may not have the same IP scheme i.e. 192.168.1.0.

2)Now suppose I make three IP groups in my network as below. Out of these three my firewall / router belongs to group 1 (VLAN1). Kindly advise how to configure and oblige.

SWITCHES   

- SWITCH 1 - L3 Mode - core routing switch 

- Switch 2 - L2 mode - department switch

- Switch 3 - L2 mode - department switch

VLANS

VLAN 1:-

IP - 10.0.7.0 255.255.255.0,

firewall - router is in vlan -1

Firewall - router ip 10.0.7.1,

all the members of VLAN 1 are on switch -1 

VLAN 2:-

IP 10.7.2.0 255.255.255.0

All the members of VLAN 2 are on switch -2 (L2 mode)

Switch 2 uplinks with core switch i.e Switch 1 with OFC port 

LAN 3:-

IP 10.7.3.0 255.255.255.0

All the members of VLAN 3 are on switch -3 (L2 mode)

Switch 3 uplinks with core switch i.e Switch 1 with Ethernet RJ 45 port

Please reply and oblige.
