Description (partial)

The new feature requirements are to match for a range of MAC addresses when defining thresholds 
for alarms

This NAM is used in a datacenter LAN for outsourcing services. Cu is especially looking for misbehaving 
servers, for example servers that cause a lot of flooding in the LAN.
Flooding in general is undesirable, affects the network and other servers  and caused several incidents already.  Microsoft NLB is a typical application that is based on flooding.
The according owner of the server would be notified to stop this behavior on the server and packet captures of the event would be triggered providing the evidence.
Cu is trying have the following
*  either a range of MAC addresses as shown (but not working)
*  some kind of wild cards using  asterisks as usual  (but not fully providing what I need) *1:*:*:*:*:*
*  another flexible solution:  regular expressions  .[0,2,4,6,8,a,c,e]:.*
*  masking MAC addresses like in MAC ACL:  value: 01:00:00:00:00:00 mask:FE:FF:FF:FF:FF:FF
