Cisco 3550 IOS - VLANs and SNMP for Network Traffic Issue


I am just starting out learning Cisco with my web hosting company I just started in December.  I am having an issue with VLAN interfaces not recording traffic though SNMP I am using Cisco IOS EMI 12.1.  Cacti usually shows an empty white space or a little traffic here and there.  But I don't think it is an issue with cacti.  Running layer 3/static routing on this vlan interface.  Below is show int Vlan command (in case its usefult to resolve my issue): int Vlan51

Vlan51 is up, line protocol is up

  Hardware is EtherSVI, address is 0016.c739.af80 (bia 0016.c739.af80)

  Internet address is

  MTU 1500 bytes, BW 1000000 Kbit, DLY 10 usec,

     reliability 255/255, txload 1/255, rxload 1/255

  Encapsulation ARPA, loopback not set

  ARP type: ARPA, ARP Timeout 04:00:00

  Last input 00:00:01, output 00:00:20, output hang never

  Last clearing of "show interface" counters never

  Input queue: 0/75/0/0 (size/max/drops/flushes); Total output drops: 4

  Queueing strategy: fifo

  Output queue: 0/40 (size/max)

  5 minute input rate 0 bits/sec, 0 packets/sec

  5 minute output rate 0 bits/sec, 0 packets/sec

     601314 packets input, 54012452 bytes, 0 no buffer

     Received 0 broadcasts (0 IP multicast)

     0 runts, 0 giants, 0 throttles

     0 input errors, 0 CRC, 0 frame, 0 overrun, 0 ignored

     596830 packets output, 52053177 bytes, 0 underruns

     0 output errors, 0 interface resets

Please advise what I need to do or what I am doing wrong again I am a newbie.
