SWITCH OCG - UDLD clarification needed
Working my way through SWITCH and came away scratching my head....
Page 212, UDLD (para 1)
UDLD messages are sent at regular intervals, as long as the link is active. You can configure the message interval UDLD uses. (The default is 15 seconds.)
Page 212, UDLD
You can use the message time keywords to set the message interval to seconds, ranging from 1 to 90 seconds. The default interval is 7 seconds.
Page 212, UDLD (note)
The default UDLD message interval times differ among Catalyst switch platforms.
So is it 15secs, 7secs or platform dependent? I'm either confused, just reading it wrong
or Cisco is just being Cisco. Nothing in the errata section on Cisco Press either. Just looking for clarification as we know how "exact" Cisco like to be about STP timers.
Edit: Just checked the FLG (v1, 642-813), it gives a default value of 15 seconds...so I guess thats the answer (hopefully).

iirc it's 15 secs (so 3x times udld packets is just below STP timers maxage+2xforward delay).
