Hi Anthena1390
My email will be iarroyo@cisco.com. When you respond back to the email can you let me know what devices will be communicating on VLAN 99. Is there a major reason for SG300 to pass DHCP as suppose your router? Well i would like to attach some screenshots, they will show you how to properly configure a P2p link, assign DHCP pools, how to properly add default routes. Send an email and lets get your issue resolved.

My name is Ismael. Iam with the Small Business Support team. From my understanding you would like to be able to pass traffic between vlan 1 and Vlan 99. Inter vlan is usually operational once SVI's for every vlan are created. I have seen ip default-gateway for Vlan 99, but not for Vlan 1. This is why they are not seeing each other. They should be able to communicate once you get SVI created for VLAN 1. Let me know if you have further questions

Hello Ismael,
Thanks for your answer.
VLAN 1 already has an IP ( ip address 10.0.0.1 255.255.255.0).
However, how can I create a default gateway for VLAN 1, as its interface (10.0.0.1) configured inside the SG300, and used as default gateway for network 10.0.0.0 ?
How could I define another gateway for this network ?
When trying to add 10.0.0.1 as gateway for it, I receive an error message "Gateway cannot be one of the addresses configured on this device".

If you have assigned ip address for VLan 1 under Ip Configuration>>>Ipv4 Interface. Then its all set for an SVI and DG. Instead of using the SG300 ping tool. Can you ping from vlan1 and vlan 99 on 2 different PC'?
09-08-2014 11:02 AM
Hi Ismael,
Yes, 10.0.0.1 has been assigned to IPv4 Interface of VLAN1.
No, I cannot ping from one VLAN to the other. Even the SG300 interface cannot be reached from the other VLAN (I cannot ping 10.0.0.1 from NW 192.168.0.0 and vice-versa).
09-08-2014 11:46 AM
I set the "Interface VLAN mode" of port 1 to "General"; and I'm now able to ping a switch port of a VLAN from another VLAN (I can ping 192.168.0.2 from PC 10.0.0.3).
But I'm still unable to ping default gateway 192.168.0.1 from PC 10.0.0.3
Any idea about the issue and a potential solution ?

Hi Anthena1390
Is the router's gateway and SG300 on 192.168.0.1? If this is the case you will most definitely not be able to get those pings to communicate. Router would have to be on a P2P link with a /30 on its own DG. If you provide me an email i can send you several screenshots of how to get this to work. On interface 1 i believe if you have a pc on it, you would only need to set it as an access port. General port will not do any good as the pc will only understand untagged traffic.

Hi Ismael,
Router's gateway is on 192.168.0.1; and SG300 interface is on 192.168.0.2.
From the 192.168.0.2 inbterface of SG300, I can ping 192.168.0.1. But from any other device on other VLAN, no (but they can ping 192.168.0.2).
Network 192.168.0.0 (between router and SG300) has a /27 mask.
OK, I will try to set port 1 as "Access".
Currently, the ports configuration are :
How can I send you a PM ?

Hi Ismael,
Thanks a lot four your help, it work much better now.
From every VLAN, I can now reachthe Internet.
However, I cannot ping from one VLAN to another.
I can ping every SG300 interface from every VLAN, but I cannot reach the PC installed in the VLAN itself (except for the WAN (default gateway) VLAN).
Therefore, routing via the default gateway works fine, but routing from 1 VLAN to another not.
How can this issue be solved ?
Thanks in advance for your help.

Ping from other VLAN were blocked by local (PC) Firewall.
I allowed the PC to answer ICMPv4, and it works !!!

Hi,
I have the same problem, you can help me pubblishing the solution, please.
thank you in advance.

Hi auhcec001,
I followed the step-by-step configuration example.
http://networklessons.com/switching/cisco-small-business-switch-vlan-configuration/
And, it works to provide Internet access for each VLAN.
However, the VLAN to VLAN routing remain a problem...

Hi Athena1390,
thank you for your reply.
I have no internet access in one vlan.
where can I find how to assign ip route ?
09-10-2014 04:34 AM
Try this :
1) Connect 1 device in this VLAN and check its IP and gateway (his VLAN interface IP)
2) Add a default-gateway in the IPv4 configuration menu of the SG300 :
Hope this help
