PortFast
[edit]There is no mention of Cisco's PortFast STP optimization in this article or elsewhere on Wikipedia. My understanding is that when enabled, PortFast puts a port into forwarding mode immediately after link is established. This gives end stations immediate connectivity at the expense of the possibility of a brief storm if the connection results in a loop. I believe the PortFast option was incorporated into the RSTP enhancement but I need someone to verify this before editing the article. Meanwhile, I've removed recent edit claiming that Blocking is the initial state for STP. While the statement is true for the original 802.1D, it needs some qualification given the above. --Kvng (talk) 13:31, 25 August 2008 (UTC)
- Still no discussion of portfast here or elsewhere on Wikipedia. ~Kvng (talk) 02:16, 25 November 2023 (UTC)
Merge from Bridge protocol data unit
[edit]- The following discussion is closed. Please do not modify it. Subsequent comments should be made in a new section. A summary of the conclusions reached follows.
- The result of this discussion was merge due to lack of discussion. OrdinaryGiraffe (talk) 23:22, 16 March 2024 (UTC)
Spanning Tree Protocol § Bridge protocol data units already appears to be more comprehensive than Bridge protocol data unit so the latter is likely not necessary. Anything not already covered here can be merged and Bridge protocol data unit turned into a redirect. ~Kvng (talk) 14:30, 20 August 2023 (UTC)
Switched MACs (BPDU header)
[edit]Hi,
Could you please explain why are the MACs switched (i.e., SMAC before the DMAC) in the header picture, under "Bridge protocol data units"?
Thanks. Regards, Rui Costa Rjfcosta (talk) 09:30, 9 October 2025 (UTC)
- That looks like an error to me. DMAC comes first in an Ethernet frame. ~Kvng (talk) 20:24, 16 October 2025 (UTC)
