Spanning-tree portfast

Is it recommended or not to enable portfast on a port connected to a router?

Re: Spanning-tree portfast

You can enable portfast on a port that is directly connected to a specific host (router, PC, etc.) without issue. It's a good idea to always have portfast disabled on switch-to-switch ports.

Re: Spanning-tree portfast

Is the port being used as an access port or trunk port. disable portfast on a trunk port, enable it on an access port.

Re: Spanning-tree portfast

Hi, it's possible to enable PortFast on a trunk port if it's connected to a router ("router on the stick" interVLAN routing, e.g.)

See http://www.cisco.com/en/US/customer/products/hw/switches/ps708/products_configuration_guide_chapter09186a0080121d37.html#1052482

for details.

Regards,

Milan
