Is there a L3 SVI on the switch and is it up/up ie. on the 3750
3750# sh ip int brief
Is the port that connects the switch to the router in the same vlan.
It might be a good idea if you could post the configs or at very least supply full IP details.

Hi Mahesh
Connect your switch via console and make sure you have assigned an IP to your native VLAN (it is usually vlan 1). For telnet, check your line vty settings in switch

I am not sure which is a typo, but there is a mismatch in the first octet of the address that you seem to be looking for and the address in the results from the router:
sh ip arp 43.140.92.5
Protocol Address Age (min) Hardware Addr Type Interface
Internet 33.140.92.5 71 001a.8054.2529 ARPA FastEthernet0
Is the first octet supposed to be 33 or 43?
Correct whichever is not correct.

Hi rick,
43 is correct IP

Mahesh
Then why does 33 appear in the output from the router?

If you are trying to access any of the vty sessions on the switch via a network connection you may want to plug in console and make sure you don't have an ACL blocking your incoming connections. As well as ensure that the ip address is specified with the correct IP address and subnet mask on interface vlan 1. And make sure you have performed a no shut command on int vlan 1
