Release	Modification
12.4(2)MR	This command was introduced.
12.4(4)MR	The command output was modified to include information related to the
	exceeding of the Maximum Transmission Unit (MTU) of the backhaul link
	(see Note).

Examples	The following is an example of the output generated by this command.
	Router# show umts packets atm 0/1/0
	UMTS-Iub(ATM0/1/0): packets:
	rxUMTS_count ================ 288799
	txUMTS_count ================ 288799
	rxUMTS_bytes ================ 13862352
	txUMTS_bytes ================ 13862352
	rxBackhaul_packets ========== 238484
	txBackhaul_packets ========== 247328
	rxBackhaul_bytes ============ 156844691
	txBackhaul_bytes ============ 15736957
	txBackhaul_pak_overrun ====== 0
Note	The txBackhaul_pak_overrun line in the show umts packets command represents the number of times
	that the MTU of the backhaul link was exceeded. It does not indicate a major problem, nor does it
	indicate any loss of data. However, if you choose a umts backhaul-timer that is too large, then the amount
	of data that is available during that time period may exceed the allowed MTU of the backhaul causing 2
	backhaul packets to be sent. This reduces the umts backhaul efficiency. The allowed MTU is 450 bytes
	for Multi-Link Point-to-Point Protocol (MLPPP) backhauls and for other backhaul interfaces, such as
	GE, the allowed MTU is the physical interface MTU less the backhaul packet overhead (which is
	approximately 4 bytes).
