Hi I am getting DHCP snooping error on switch for Phone connected to 2960 switch. Also Phone is not getting IP address.
DHCP_SNOOPING-5-DHCP_SNOOPING_NONZERO_GIADDR: DHCP_SNOOPING drop message with non-zero giaddr or option82 value on untrusted port, message type: DHCPDECLINE, MAC sa: 34dc.fde5.2c40

Pawan,
Based on the error messages it looks like you have a mis-configuration. Looks like
one of the trunks/ports does not have DHCP trust configured on it. Can you
track mac address 34dc.fde5.2c40 to what port it's connected to and verify
that it has DHCP trust enabled?.
