Hi,

I'm trying to setup the Cisco 3750 switch but I just couldn't get the PC on port 2 (no VLAN set PC IP to 10.12.10.2.24) and PCs on VLAN 30 to reach the Internet.

Hope someone can assist, thanks.

Hello

with regards to port 2, its in default vlan 1, and vlan 1 is shutdown on layer 3.. hence you will not be able to browse internet thro port 2. you assign the port onto a different vlan and create layer 3 vlan interfaces to enable routing or configure vlan 1 with IP address. with vlan 30, what is the default gateway of the PC ? is 10.12.10.252 the internet router ? Are there reverse routes on the router pointing back to the layer 3 switch for reachability to VLAN 30 ? Are there any NAT statements configured ?

Let us know
