      A bunch of backend delay node changes. Change the delays DB table to · fe13d60f
      Leigh B. Stoller authored
      hold separate values for each of the two pipes. This allows us to
      treat the links asymmetrically with respect to the delay node
      configuration. Changes to tmcd to return the expanded info, and rework
      (completely) delay_config to allow user to change the duplex
      characteristics (just like before), or just simplex characteristics by
      specifying the pipe number. By convention (I invented) pipe 0 is
      traffic coming in on iface0. Of course, none of the front end stuff
      has been changed, so the changing a single pipe does not cause
      anything in virt_lans to be changed, so those changes will be lost at
      swapout. Also get rid of all the ssh'ed pipe config stuff in
      delay_config. Instead, add a client side script called update_delays
      to /etc/testbed on the experiment nodes. After updating the delays
      table, just ssh over and run that script, which calls the existing
      code. Less distribution of knowledge.

      Major overhaul of snmpit. Highlights, in no particular order: · 7e53c10a
      Robert Ricci authored
      Now supports multiple switches and multiple stacks. To do this, the existing
      snmpit_cisco module had to be modified to behave as a true object, and its
      interface changed.
      
      A new layer of abstraction has been added: the stack. This is to hide the
      details of how things such as VLAN creation occur across multiple devices. For
      example, in Cisco stacks, you always contact the stack leader (VTP server) to
      create/delete VLANs. Other switches may have different semantics, such as
      having to contact every switch to create the VLAN.
      
      Now uses libdb for database access and permissions checks.
      
      Hardware details are hidden as much as possible in the user interface. For
      example, the creation and deletion commands now take VLAN identifiers, and
      snmpit transparently turns these into device-specific VLAN numbers.
      
      snmpit.in has been re-written from scratch. The new version uses three basic
      steps:
      1) Process command line options and determine operation to run
      2) Determine which devices, ports, and VLANs will be involved and make
         the appropriate objects
      3) Actually perform the operation
         when TESTMODE is set, does only steps 1 and 2
      
      Some command-line options have changed. This is because we now use getopt,
      rather than a home-grown parser, to parse the command line. As a result of the
      large number of options, and an attempt to mimic old options as much as
      possible, the options are no longer very mnemonic.
      
      Uses a new table called switch_stacks to figure out which switches belong to
      which stacks. A stack is defined as a set of switches that share VLANs.
      
      All snmpit scripts and modules now run with 'use strict' to help catch certain
      programming errors.
      
      VLAN listing now prints out the pid/eid and vname for VLANs, if possible.
      
      A few things have bitrotted due to these changes:
      * snmpit_intel will need to be re-tooled to use the new interface, and to
        behave as a proper object
      * vlansync, vlandiff, and resetvlans depend on the output of snmpit, and will
        need to be updated to understand its new output format
