Poor mans TAP

[dovid at telecurve.com (Dovid Bender)]

Yup, Tried that. Incoming interface is set as:
interface Ethernet1/37
  switchport mac-learn disable
  description tor-31-1 ge-0/0/44 SPAN
  switchport mode trunk
  switchport trunk allowed vlan 2,999
  ip access-group DROP out

Outbound interfaces are set to:

interface Ethernet1/46
  description MON1
  switchport access vlan 999

The issue is that the traffic coming in, is coming from a Juniper switch
where the traffic has vlan tags on the packets.
