Can the Cisco SF302-08 switch support IP routing capabilities?

mema7261

Level 1

I'm currently working on configuring inter-VLAN routing on a Cisco SF302-08 switch. I've already enabled Layer 3 routing, created the VLANs, assigned them to switchports, and configured the switch VLAN interfaces accordingly. However, I'm encountering difficulties at the step where I need to configure a routed port or a static route. Despite attempting these configurations, I'm unable to achieve successful communication between the different VLANs.

The switch's configuration:

show running-config:

v1.4.0.88 / R800_NIK_1_4_194_194 CLI v1.0 set system mode router

! vlan database vlan 10,20 exit

interface vlan 1 
ip address 101.205.25.252 255.255.255.0  
no ip address dhcp 
!
interface vlan 10 
ip address 101.205.10.1 255.255.255.0 
! 
interface vlan 20  
ip address 101.205.20.1 255.255.255.0 
! 
interface fastethernet3  
switchport mode access  
switchport access vlan 10 
! 
interface fastethernet4  
switchport mode access  
switchport access vlan 20 
! 
interface fastethernet5  
switchport trunk allowed vlan add 10,20 
! 
interface fastethernet7  
switchport mode access  
switchport access vlan 10 
! 
interface fastethernet8  
switchport mode access  
switchport access vlan 20 
! 
exit 
ip route 101.205.10.0 /24 101.205.25.254
 

Consequently, I am seeking assistance to resolve this issue. Any guidance or support offered would be greatly appreciated.

the router config seems ok,
but do you have fixed IP-address configuration for your clients?
if not where is your DHCP server located ?
-> you need an ip-helper address configured on the vlan's/ SVI's that are not directly connected to the DHCP-server vlan

Cisco Small Business 300 Series Command Line Interface Guide Release 1.2.5/1.2.7
37.14 ip helper-address

Thank you for your response.

I've set up static IP addresses for all clients in the network. Although I appreciate your suggestion about using an ip-helper address, I'm curious if it would still be beneficial given that the fixed IP configurations already in place.

If DHCP is not used, then ip-helper is not needed / will not improve the routing behavior

what unsuccessful communications are you talking about ?

NB! the windows firewall by default only allows incoming trafic from the local subnet
so it will not allow icmp/ping or remote-desktop connections from another subnet
-> you need to modify the windows firewall configuration,  (or simply disable temporarily  to perform your tests)
