Hello Dipak,
the router needs a static route for network 172.16.30.0/23 in order to answer to ICMP request sourced by 192.168.30.254
on the router
config t
ip route 172.16.30.0 255.255.254.0 192.168.9.254
exit
wr mem
This should fix your issue, to be noted it is not the switch the one that needs a configuration change.
Hope to help
Giuseppe
