  • Cisco interface counters

    We had freebsd router, and some days ago replaced it on cisco 7507 (it isn't new model btw).
    Network graph is built by snmp and mrtg, but after implemeted cisco.
    The graph changed and upload and download have approximately the same value.
    I wrote only one command to turn on snmp.
    snmp-server community ******* RO snmpaccess
    Here is a sample target from mrtg config
    Target[r2_114]: -\GigabitEthernet1/0/0.114:********@***************
    GigabitEthernet1/0/0 is up, line protocol is up
      Hardware is cyBus GigabitEthernet Interface, address is 
      MTU 1500 bytes, BW 1000000 Kbit, DLY 10 usec,
         reliability 255/255, txload 8/255, rxload 8/255
      Encapsulation 802.1Q Virtual LAN, Vlan ID  1., loopback not set
      Keepalive set (10 sec)
      Full-duplex, 1000Mb/s, link type is autonegotiation, media type is unknown media type
      output flow-control is XON, input flow-control is XON
      ARP type: ARPA, ARP Timeout 04:00:00
      Last input 00:00:00, output 00:00:00, output hang never
      Last clearing of "show interface" counters never
      Input queue: 0/75/1518/12 (size/max/drops/flushes); Total output drops: 776174
      Queueing strategy: Class-based queueing
      Output queue: 0/40 (size/max)
      30 second input rate 33178000 bits/sec, 7420 packets/sec
      30 second output rate 33451000 bits/sec, 7365 packets/sec
         5479760078 packets input, 3179334508875 bytes, 0 no buffer
         Received 7740780 broadcasts, 0 runts, 0 giants, 52 throttles
         1618412 input errors, 0 CRC, 0 frame, 4455 overrun, 1613957 ignored
         0 watchdog, 0 multicast, 0 pause input
         0 input packets with dribble condition detected
         5460239267 packets output, 3172517559628 bytes, 0 underruns
         776174 packets late drop, 1159831544 bytes late drop
         0 output errors, 0 collisions, 2 interface resets
         2 unknown protocol drops
         0 babbles, 0 late collision, 0 deferred
         8 lost carrier, 0 no carrier, 0 pause output
         0 output buffer failures, 0 output buffers swapped out
    On this graph you can see differences between freebsd and cisco.

    My be you know how to solve this ?

    Could be a duplex or speed mismatch.
