Architecture Problems
GigabitEthernet1/0/0 is up, line protocol is up
Hardware is epif_gigether_port, address is 00d0.baaf.76fb (bia 00d0.baaf.7703)
MTU 1500 bytes, BW 1000000 Kbit, DLY 10 usec, rely 255/255, load 1/255
Encapsulation ARPA, loopback not set, keepalive set (10 sec)
Full-duplex, 1000Mb/s, GBIC not connected, Force link-up
ARP type: ARPA, ARP Timeout 04:00:00
Last input never, output never, output hang never
Last clearing of "show interface" counters 23w4d
Queueing strategy: fifo
Output queue 0/40, 0 drops; input queue 0/75, 0 drops
5 minute input rate 1248000 bits/sec, 502 packets/sec
5 minute output rate 1487000 bits/sec, 490 packets/sec

Received 0 broadcasts, 0 runts, 0 giants, 0 throttles
0 input errors, 0 CRC, 0 frame, 0 overrun, 0 ignored, 0 abort
0 watchdog, 430232925 multicast
0 input packets with dribble condition detected
1164199966 packets output, 4006760239 bytes, 0 underruns(0/0/0)
0 output errors, 0 collisions, 0 interface resets
0 babbles, 0 late collision, 0 deferred
0 lost carrier, 0 no carrier
0 output buffer failures, 0 output buffers swapped out

Step 2 Check the no buffer field to see whether the count is a high percentage of the packet input. If the number
is too high, proceed with the following process to fix the problem.
Step 3 Reduce any unneeded multicast traffic on the VLANs.
Step 4 To reduce traffic on the ATM switch router, enable IGMP snooping on the connected Ethernet switches.
Step 5 Increase the input and output hold queues on the Gigabit Ethernet interfaces. Try doubling the value of
the input and output hold queues using the processes described in Step 6 through Step 8.
Step 6 Enter the show interfaces card/subcard/port command to verify the values of the input and output hold
queues on the Gigabit Ethernet interface.

Step 7 Verify the Output queue and input queue fields. In this example the output queue is configured to 40 and
the input queue is configured to 75.
