Method: Net::SNMP::Session#get_table

Defined in:
lib/net/snmp/session.rb

#get_table(table_name, options = {}) ⇒ Object

XXX This needs work. Need to use getbulk for speed, guess maxrepeaters, etc.. Also need to figure out how we can tell column names from something like ifTable instead of ifEntry. Needs to handle errors, there are probably offset problems in cases of bad data, and various other problems. Also need to add async support. Maybe return a hash with index as key?
