Hello all:
I too have encounterd a simular problem.
It appears that this email was lost among all of the others:
Is anybody able to explain the difference between the vlan access-map and
the extended mac access-list

Thank you very much.

  Dear all, Q refers to IEWB Lab6 9.1, but it is a general question
  anyways. The task asks to filter DEC spanning tree bpdus and offers a
  clan access-map as the solution:

  vlan access-map DECNET 10
  action drop
  match mac address DECNET
  vlan access-map DECNET 20
  action forward
  match mac address ANY>>MAC
  vlan filter DECNET vlan-list 363

  mac access-list extended ANY>>MAC
  permit any any
  mac access-list extended DECNET
  permit any any dec-spanning

  I fully understand the technology here, but I am wondering if an
  extended mac ACL here would also work and have *exactly* the same
  functionality?

  All VL363 ports are access ports in this example:

  mac access-list extended DECNET
  deny any any dec-spanning
  permit any any

  interface FastEthernet0/24
  switchport access vlan 363
  switchport mode access
  mac access-group DECNET in
  !

  TIA,

  BTW, Thanks Brians for hosting that online session- it was extremely
  informative!!
