Cisco 300 series: my PCs cannot reach the 2nd subnet

Dear Community/Support:

 

setting up our new series 300-28 in Layer3 Mode with a very basic network setup:

LAN: 192.168.0.0/24

VOIP Switch: 10.128.0.1 -- attached to GE24

__________________________

default VLAN1- 192.168.0.254

added IPv4 Interface: GE24-10.128.0.254

which added the IPv4 route to the subnet 10.128.0.0

which added the ARP entry for 10.128.0.1

so in the admin interface the 300 can ping 10.128.0.1,

but my PCs in VLAN1 cannot reach it at all.

__________________________

300-28 has DHCP enabled, IP Range 192.168.0.9-99/24, Gateway 192.168.0.254

i simply fail to understand why :(

Sorry I don't really know the

Sorry I don't really know the 300 series range of products. On other devices you would need to enable IP routing.

Have a look at this link it talks about changing the system mode to layer 3?
