[ixpmanager] Recommended Devices for an IXP with Sflow Feature

[Moritz Frenzel]

Hello Ahmed,

you may find this "wishlist" by euro-ix useful in order not to miss
anything: https://www.euro-ix.net/en/forixps/ixp-wishlist/

Also all IXPs running IXPManager expose the used devices in the IX-F
format, if you check the switch section you'll find all models in
operation, see ours for example:
https://portal.s-ix.de/api/v4/member-export/ixf/1.0
EURO-IX also consolidates all endpoints they're aware of into the IXPDB
https://ixpdb.euro-ix.net/en/, maybe you'll find more information there.

Our(Stuttgart-IX) main switch is a Arista 7280-SR-48C6, we're very happy
with it, especially as it supports L2 and L3 ACLs which allow us to
implement all MANRS actions as well as BGP Session culling when needed,
this hardware platform is also present in a few other IXPs in Germany and
Austria.

Best of luck in finding a new switch.

Moritz
Stuttgart-IX
