  Supports extended VLANs (1006 - 4094)

  VTP can now be turned off completely, as opposed to just transparent mode Fixes the bane of VTP v1/2, the accidental-high-configuration-revision-wipes-out-your- network issue, by design it does this no configuration is necessary.

• Question 689:

  Which statement describes what happens if all VSL connections between the virtual switch members are lost?

  A. Both virtual switch members cease to forward traffic.
  B. The VSS transitions to the dual active recovery mode, and both virtual switch members continue to forward traffic independently.
  C. The virtual switch members reload.
  D. The VSS transitions to the dual active recovery mode, and only the new active virtual switch continues to forward traffic.
  D. The VSS transitions to the dual active recovery mode, and only the new active virtual switch continues to forward traffic.

  Q. What happens if all VSL connections between the virtual switch members are lost? A. VSLs can be configured with up to eight links between the two switches across any combination of line cards or supervisor ports to provide a high level of redundancy. If for some rare reason all VSL connections are lost between the virtual switch members leaving both the virtual switch members up, the VSS will transition to the dual active recovery mode. The dual active state is detected rapidly (subsecond) by any of the following three methods: Enhancement to PAgP used in MEC with connecting Cisco switches L3 Bidirectional Forwarding Detection (BFD) configuration on a directly connected link (besides VSL) between virtual switch members or through an L2 link through an access layer switch L2 Fast-Hello Dual-Active Detection configuration on a directly connected link (besides VSL) between virtual switch members (supported with 12.2(33)SXI) In the dual active recovery mode, all interfaces except the VSL interfaces are in an operationally shut down state in the formerly active virtual switch member. The new active virtual switch continues to forward traffic on all links. Reference: http://www.cisco.com/en/US/prod/collateral/switches/ps5718/ ps9336/ prod_qas0900aecd806ed74 b.html
