Hello. I'm trying to implement the UDLD protocol (Cisco-compatible), but face some problems. There is no enough information for implementing this protocol neither in RFC 5171 (http://tools.ietf.org/html/rfc5171) nor on cisco.com (articles http://www.cisco.com/en/US/docs/switches/lan/catalyst3550/software/release/12.1_19_ea1/configuration/guide/swudld.html and http://www.cisco.com/en/US/tech/tk389/tk621/technologies_tech_note09186a008009477b.shtml). How can I get a more detailed information regarding protocol state machines and timers? Thanks in advance.
