Hi All, I recently setup new 3750x switches in my network and created vlans to expand my network. I assigned an interface Gi1/0/1 ip 192.168.1.253 so it act as an gateway for my VLANs. The vlan works fine in this case but only problem is that my default vlan 1 does not have any connectivity. What have i done wrong? i have attached the config of my switch. Thanks for your help. interface GigabitEthernet1/0/1 description Default Gateway for VLAN no switchport ip address 192.168.1.253 255.255.255.0 ! ! interface GigabitEthernet1/0/2 switchport mode access speed 1000 duplex full ! interface GigabitEthernet1/0/3 ! interface GigabitEthernet1/0/4 ! interface GigabitEthernet1/0/5 ! interface GigabitEthernet1/0/6 ! interface GigabitEthernet1/0/7 ! interface GigabitEthernet1/0/8 ! interface GigabitEthernet1/0/9 ! interface GigabitEthernet1/0/10 ! interface GigabitEthernet1/0/11 ! interface GigabitEthernet1/0/12 switchport access vlan 4 switchport mode access ! interface GigabitEthernet1/0/13 switchport access vlan 2 switchport mode access speed 100 duplex full ! interface GigabitEthernet1/0/14 switchport access vlan 2 switchport mode access ! interface GigabitEthernet1/0/15 switchport access vlan 2 switchport mode access ! interface GigabitEthernet1/0/16 switchport access vlan 2 switchport mode access ! interface GigabitEthernet1/0/17 switchport access vlan 2 switchport mode access ! interface GigabitEthernet1/0/18 switchport access vlan 2 switchport mode access ! interface GigabitEthernet1/0/19 switchport access vlan 2 switchport mode access ! interface GigabitEthernet1/0/20 switchport access vlan 2 switchport mode access ! interface GigabitEthernet1/0/21 switchport access vlan 2 switchport mode access power inline port priority high flowcontrol receive on ! interface GigabitEthernet1/0/22 switchport access vlan 2 switchport mode access ! interface GigabitEthernet1/0/23 description ***Trunking Ports*** switchport trunk encapsulation dot1q switchport mode trunk speed 1000 duplex full ! interface GigabitEthernet1/0/24 description ***Trunking Ports*** switchport trunk encapsulation dot1q switchport mode trunk speed 1000 duplex full ! interface GigabitEthernet1/1/1 description ***Uplink-to-Warehouse-Cisco3750G*** switchport trunk encapsulation dot1q switchport mode trunk udld port storm-control multicast level 50.00 ! interface Vlan1 no ip address ! interface Vlan2 ip address 192.168.2.254 255.255.255.0 ip helper-address 192.168.1.101 ! interface Vlan4 ip address 192.168.4.254 255.255.255.0 ip helper-address 192.168.1.101 ! interface Vlan8 no ip address ! ip classless ip route 0.0.0.0 0.0.0.0 192.168.255.1 ip route 192.168.0.0 255.255.0.0 192.168.1.254 ip route 192.168.1.0 255.255.255.0 192.168.1.254 ip http server ip http secure-server ! ip sla enable reaction-alerts ! ! line con 0 line vty 0 4 password bmw328i login line vty 5 15 password bmw328i login ! end

Thanks for your reply Mika, Our company was running on a mix network ie we do not have a unified network platfrom. My focus at the moment is slowly upgrading this network to use cisco but because we have a budget so we cannot replace everything at once hence have netgear connecting to cisco etc. do you think this is a sign of looping in my network? If so what can i do to prevent this? FYI, i do have RSTP enable as well as loopguard. I will look into the netgear to see if anything is unusual about port channel setting.

Hi Alain, Here is the topology of my switches, and router, the 3750G is the only switch that holds all the current vlan and ideally i like to have the new 3750x setup with vlan for redundancy. Thanks

Hi Giuseppe, When I enter this static route it come back with the following message Cisco3750x(config)#ip route 192.168.2.0 255.255.255.0 192.168.1.252 %Invalid next hop address (it's this router) Thanks.

Hi Alain, Sorry for the confusion, i should have mentioned that the 192.168.1.254/24 is the ip address of my existing router hence the default gateway for the 1 subnet. What I am trying to do is assigning the 192.168.1.252 ip to the switch and create vlans on it to expand my network. Should i be assigning that ip (192.168.1.252) to the switch interface instead and use that that interface as default gateway for the vlan? Thanks.

Thanks for your reply Alain, 192.168.1.252/24 is the ip address and default gateway i assigned to the switch throught the Express setup. The actual default gateway for the subnet 1 network is 192.168.1.254/24. When i set up hosts on vlan 1 on this switch it can ping all hosts on the network fine excepted for hosts on the vlan 2 i created within the 3750x. And vice versa, any devices on the local 2 subnet cannot ping anything else besides 192.168.2.254/24 and 192.168.1.252/24. Thanks for your help.

Hi Everyone, I am a cisco newbie and would like to seek some professional advice on setting up intervlan routing on my cisco 3750x. I recently purchase this switch and has setup vlan 2 under subnet 192.168.2.0/24, and has enable ip routing so that it can communicate with vlan 1(default) on subnet 192.168.1.0/24. So far i have setup vlans, routing on the L3 device but still having issue communicating between the vlans. below is my vlan details and static routing.
