The ping does not respond. Can anyone identify the issue here?

When you say "ping" where are you pinging from ?.
Can you also post:
sh int vlan 34
sh int g0/15
sh int g2/22

Also, could you confirm if your trunk is up.

You have a duplicate address somewhere.
The first switch has local address of 49.16.20.1 and check the MAC Address 0015.c73a.6000.
Now the switch holding the address of 49.16.20.11 sees a device holding address 49.16.20.1 but check the MAC Address 001e.7a29.fd40
