Unused Tail Characteristics

["Matt Duggan" <matt.duggan () world-data-systems com>]

Hi Everyone,

We have a customer who needs to be able to identify unused tails throughout
their large Cisco-based network. What are the groups thoughts regarding a
bullet-proof set of characteristics that could be used to 'discover' unused
tails?
(using SNMP queries and/or telnet/ssh access to the devices)

I guess clocking would be a good start......

regards,
Matthew.
