Appendix A Cisco 3825 Mobile Wireless Edge Router RAN-O Command Reference
show umts-iub packets
show umts-iub packets
To display packet statistics of the UMTS-Iub interface, use the show umts-iub packets command in
privileged EXEC mode.
show umts-iub packets
Syntax Description This command has no arguments or keywords.
Command Modes Privileged EXEC
Command History
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).
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).
