IX port security

[Greg VILLAIN <nanog () grrrrreg net>]

Hi all,

Thinking back about this thread we've had lately around IXes, I have  
some extra questions.
It is I assume the IX's responsibility to protect members from harming  
each other through the peering LAN.
For that purpose, the IX has to do some minimum sanity checks before  
letting a member in into the production VLAN, for instance by using a  
quarantine VLAN to probe its traffic first.
Then, once those checks are done, the IX shall apply a minimum  
security configuration to each member port:
1/ limiting broadcast/unknown unicast on each member port
2/ filtering bpdu
3/ locking mac addresses

Here are my questions:
- re 1/, any clue about the PPS or %bandwidth values to be configured  
to limit broadcast/unknown unicast ?
- re 3/ should a certain number of allowed mac-addresses be configured  
to the port (1 or 2) ? or should the customer's port mac be explicitly  
configured on the port ?
- more importantly, is there any other standard precaution that I'm  
missing and that should be considered ?

cheers,
