      When removing VLANs, get a new lock on the edit buffer for each VLAN · e5986abc
      Robert Ricci authored
      we're going to remove. We used to do all VLANs in one lock for
      performace reasons - however, I'm discovering that the lock can get
      held for such a long time when many VLANs are being deleted that other
      VLAN operations, such as listing VLANs, can fail. And, it's not
      actually that much slower to grab a new lock each time.

      The real reason for doing this, though, is robustness - the old
      code was terribly fragile, depending on several tables being in order,
      etc. This was breaking on some of our new switches.
      Also fix a few typos in debugging messages.

      snmpit_cisco: hack to get around 2950 switch returning just <port>
      rather than <module>.<port> in interface info tables.
      Note: snmpit_cisco does not successfully return speed/duplex info for -b,
      this may cause problems with whack-on-lan and needs to be fixed!

      Terrible hack. · 5cf8cbc1
      Robert Ricci authored
      Non-modular switches with two different types of interfaces give us
      trouble under IOS because they appear to be on the same module, but
      the duplicate card numbers. ie. Fastethernet0/1 and Gigabitethernet0/1
      Hack around this by pretending the gigabit ports on such a switch are
      on module 1, not module 0.
      This works fine on the 29xx series, but probably won't work well for
      anything else. The real solution is to move to iface instead of
      card.port, or use a type.card.port triple.
      In order to invoke this hack, you must put '-modhack' in the type for
      the switch in the nodes table.

      Add user-visible support for trunking. · cfdf5c00

      Added support for Cisco switches to enable and disable trunking for a

      -N <port> <vlans>
      	Enable trunking on a port, allowing the given list of VLANs to

      -U <port>:
      	Disable trunking for the port
      This functionality is needed for Mike's firewall support.

      take more than one. This can increase efficiency, since, for example,
      we now only have to lock the VLAN edit buffer once when tearing down
      an experiment, instead of once per VLAN. There are still other
      functions (setVlanOnTrunks comes to mind) that could benefit from this
      These optimization have been made only for Ciscos - minimal changes
      necessary to keep Intel support working were made, but they will still
      have the same old slow behavior.

      return value on VLAN creation. If it reports success, we look for the
      VLAN with findVlan(), to make sure it's really there. We retry a
      couple times if it didn't work. This will add a small (sub-second)
      time penalty per VLAN created.
      We ran into one instance, that we've noticed, where the switch
      reported that VLAN creation succeeded, but the VLAN did not actually
      get created on the switch.

      Change the way we set VLANs very slightly. We used to use the vmVlan · a5e752fb
      Robert Ricci authored
      OID from the CISCO-VLAN-MEMBERSHIP MIB. But, this MIB does not seem
      to be supported by all Cisco switches. So, we now use vlanPortVlan
      from the CISCO-STACK MIB.
      So, we no longer need CISCO-VLAN-MEMBERSHIP-MIB at all, which should make
      snmpit usable on a wider variety of Ciscos.

      Actually call the code to pick which VLANs are allowed on which trunk. · afb28fde
      Robert Ricci authored
      When dealing with trunks, since they may be EtherChannels, we have to
      make another lookup on the switch to get the ifIndex for the whole
      channel - can't just use the ifIndex of one of the ports like you
      can from the Cisco CLI.
      These changes make snmpit slightly slower - it now has to get more information
      from the switches when it's going to create or delete VLANs. However, this
      is on the order of fractions of seconds, so it shouldn't be too noticable.

      Code for picking which VLANs are allowed to go across which trunks. · 11e0ea5f
      Robert Ricci authored
      As much of it as possible switch-independant, and put in snmpit_lib.
      Should work for arbitrarily complicated switch toplogies, as long as
      there are not multiple trunks between two switches. (Multiple ports
      combined into one trunk are fine, however.)
      As a result of this, VLAN creations and deletions now need to operate
      on all switches, not just on the ones that have ports in the VLAN.
      This is because the traffic may have to traverse switches that have no
      ports in the VLAN to reach other switches that do.
      Not called yet. I've done simple testing, but need to do more, as this
      could get us into major trouble if it has bugs.
