multiple IP on an interface of Cisco9300

Hi,

is there any way to assign 2 IPs to an interface of 9300.

i am running IOS XE 16.09.04 and sub-interface is not supported on this platform.

It is possible.
Look it:


The optional secondary keyword allows you to specify an unlimited number of secondary addresses. Secondary addresses are treated like primary addresses, except the system never generates datagrams other than routing updates with secondary source addresses. IP broadcasts and Address Resolution Protocol (ARP) requests are handled properly, as are interface routes

 Physcal interface or vlan

interface GigabitEthernet 1/0/1
 ip address 192.108.1.27 255.255.255.0
 ip address 192.31.7.17 255.255.255.0 secondary


interface vlan 3000 ip address 192.108.1.27 255.255.255.0 ip address 192.31.7.17 255.255.255.0 secondary
