Re: LACP 802.3ad and ng_fec ?

Thanks for your reply,

It seems that HP ProCurve 5400 series doesn't support fec trunking :

hp(config)# trunk A3-a5 trk1 fec
Invalid input: fec

hp(config)# trunk A3-a5 trk1 ?
trunk Do not use any protocol to create or maintain
the trunk.
lacp Use IEEE 802.1ad Link Aggregation protocol.
<cr>
hp(config)#

Can ng_fec handshake with switch via "trunk" option instead of "fec" ?
According to HP docs, FEC should "work" with the 'trunk' setting.
It will loose all features tough, and just become a 'dumb' bonding-style thing, with no redundancy and other features.

Yes, I was reading some HP docs yesterday and they implied that they were removing FEC on newer switches in favour of using the IEEE standards-based methods of trunking.
I can NOT resist taking the bait here: HP has supported these standards for ages.
In fact, the cisco-protocols were used to market their stuff as cisco-replacements.
They ripped out functionality. IEEE Standards were already supported.
Same for their SFP's. Vendor lock-in is a bitch, especially when that means you can't get stuff that was previously possible. (think cwdm gbics, etc)


I wonder how dissimilar FEC and IEEE LACP are from one another? ie. how much of the code from ng_fec could be used to implement an ng_lacp...
I honestly don't know :-/
I'm very interested in the whole topic though, as we're an all-HP (as in procurve) shop.
I do know that will only last 'till the next boxes we buy, HP has let us down the past few years.
