I recently purchased an SG300 switch and was not aware that Layer 3 was disabled by default. To enable it, I'd have to reset my whole config and start over again.
Is there any performance penalty to enabling Layer 3 mode on the switch? If not, then ...
I noticed (based on activity lights) that VLAN traffic between two switch ports are being sent to many switch ports. Here's my scenario:
Port 1 is a "mode access" switchport for VLAN 100 (untagged 100).
Port 2 is a "mode access" switchport for VLAN 1...
I'm trying to configure VLANs on my SG300-10PP which I just purchased. Heres my configuration:

The router is a DHCP server for vlan 100 (192.168.1.1) and vlan 101 (192.168.2.1). It sets the gateway as itself when it distributes an IP.
From a host perspective, it makes sense why the packets have to go to the gateway/rou...

Host 1 (ge1) is 192.168.1.2/24 with a gateway of 192.168.1.1 (vlan 100)
Host 2 (ge2) is 192.168.2.2/24 with a gateway of 192.168.2.1 (vlan 101)
The router at p...
If I apply that rule to "in" on GigabitEthernet0 (WAN), it doesn't work, and IOS still acts as a proxy dns to people on the internet. If I apply that rule to "out" on GigabitEthernet0, I am unable to get DNS requests out, which is expected.I don't kn...
