 Supports VLANs
o Ability to share the allocated STS-1 SPE(s) between multiple sets of
bridged LANs. Privacy is maintained between the different sets.
o Supports up to 60 „Distributed Port-based‟ VLANs (D-PVLAN) for
guaranteed isolation of traffic between ports with different D-PVLAN
membership assignments. D-PVLANs are pre-assigned to the four
TDM pipes in sets of 15. Each provisioned Ethernet access port
requires a D-PVLAN assignment (1-60).
o Supports D-PVLAN trunking (ability to assign multiple D-PVLAN
memberships to a port).
802.1Q tagged to distinguish between different D-PVLANs.
o Allows transparent transport of Ethernet frames with 802.1p and
802.1Q VLAN tags including frames with "QinQ" nested (stacked)
802.1Q tags (up to 28 levels of "QinQ" nesting; max frame length is
1632 bytes).
o Optional QVLAN filtering (per port)
 Supports all 4000 802.1Q VLANs, with up to 50 user-
configurable QVLAN memberships per port.
 Applied to both ingress (input) and egress (output) frames.
 Configurable per-QVLAN output tagging (available when QVLAN filtering is
enabled). Allows for adding ("pushing") a tag to untagged frames or
removing ("popping") the outer
 Powerful MAC address management
o A 32,768-entry MAC address table in the ETHER-1000 unit ("WAN"
switch).
o Built-in 8-port Ethernet Layer-2 switch on the base paddleboard
("LAN" switch) with 8192-entry MAC address table.
o User-configurable aging time for learned MAC addresses (ranging
from 30 seconds to 1 hour, or never).
o Configurable static (not aged) MAC addresses, 20 per port, stored in
flash.
o MAC address learning and sorting per D-PVLAN and QVLAN allows
for independent routing of frames in different VLANs even if their
source/destination MAC address is the same.
o Per-port configurable learning mode for No Blocking or Secured
(blocking, with static and pseudo-static

In QinQ frames, the outer tag (tag#1) is the one closest to the Ethernet header. The inner tag is
the one closest to the payload portion of the frame.

Some limitations apply. See MAC Address Management section.
