I’m trying to access my variable directly here rather than using puts to  
print it out. Can anyone tell me the easiest way to access it from the  
variable?

ipadd = ARGV[0]  
columns = [“ifDescr”]  
SNMP::Manager.open(:Host =\> ipadd, :Community =\> “877pricelineHOBO” ) do  
|m|  
m.walk(columns) { |row| puts row.join("\t") }  
end

thanks

Can’t test right now because I don’t have a device/system using SNMP  
handy, but, thinking it’s simply a scoping issue…

ifDescr = []

```
  m.walk(columns) { |row| ifDescr << row.join("\t") }

```

puts ifDescr
