snmp help needed

[faron.hopper]

i am trying to get a port count and if they are up/down. here is the
code i have and the problem i am having is trying to get the data out
of the snmp::manager block. I am new to ruby and am not sure how to
procede. any help is appreciated

the example code from snmplib.rubyforge.org returns this data

FastEthernet0/1 1
FastEthernet0/2 1
FastEthernet0/3 1
FastEthernet0/4 2

and i want to keep track of the digit after FastEthernet0/x. my
original thought was to create a hash and capture the port and the
status, however, i am having trouble getting my mind to grasp how the
snmp function and ruby are interacting.
