Hi All,.

Hi Gururaj,

Its very interesting question, Vwire is just a bump in cable, it pass through all Spanning-tree packets.

Topology without Vwire

SW1------------------------SW2

|                                         |

|                                         |

SW3------------------------SW4

Topology with Vwire

SW1-------------Vwire1(PAN)Vwire1-------SW2

|                                                                   |

|                                                                   |

SW1-------------Vwire2(PAN)Vwire2-------SW2

Vwire pass through all STP packets from one interface to other, its just a bump in cable. Basically it doesnt change STP Functionality.

if one interface goes down in Vwire then other goes down immediately, So there is no chance of Spanning Tree loop.
