Cisco Sg 350 series managed Switch Unable to ping gateway form interface

[lsasikumar]

Hai we recently bought a new cisco sg 350 series switch the issue  is

From switch we are able to ping the gateway 103.110.172.1

From switch we are able to ping  103.110.172.2

From switch we are able to ping  103.110.172.17

but when connected from interface GigabitEthernet1
ip address 103.110.172.17 255.255.255.240

interface GigabitEthernet26
ip address 103.110.172.2 255.255.255.240

we are able to ping both the interfaces  but from interface Gigabit Ethernet1 we are unable to ping the gateway 103.110.172.1

Routing information

103.110.172.17/28 is not in the same IP address range as 103.110.172.1/28

Try to issue:

ip routing

and add static default ip route

ip route 0.0.0.0 0.0.0.0 103.110.172.1 metric 1
