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
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).

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