McDATA ULTRANETTM EDGE STORAGE ROUTER 3000 Manual Do Utilizador

This appendix provides information about the spantree portfast 
command for Cisco routers.

When a WAN link goes down and comes back up quickly, the virtual 
circuit may take from 30 to 90 seconds to re-establish itself. The 

 command allows the Cisco router port that is 

directly connected to the UltraNet Edge 3000 to recover faster. 

Issue the 

 command only when faster recovery 

for the UltraNet Edge 3000 is necessary.
