Switching capacity
48 Gbit/s (theoretical, exceeds the maximum
interface capacity available per IDU)
MAC-table
Address table per each VLAN 128k (configurable)
VLAN
 802.1Q port and tag, tunnel
 802.1ad port and tag, selective
 4094 VLAN ID per IDU
 MEF9 certified EPL, EVPL and ELAN; L2CP
tunnelling (multicast frame
filtering/forwarding configurable)
Jumbo frames
max. 2000/9600 octets (FE/GE)
QoS
Ingress ports
 Configurable mapping QoS -> internal
priority: based on VLAN CoS/IPv4
DSCP/IPv6 DSCP/MPLS Exp
 Configurable mapping internal priority ->
4/8 egress queues (port based setting:
default one to one and two user profiles
plus one user-defined DSCP profile i.e.
four profiles total per IDU)
 MEF/RFC4115 based ”policing”
(CIR/EIR/CBS/EBS) per QoS-class and
optionally per VLAN
For each egress port
 Queuing 4 or 8 classes 4xSP, 4xDWRR,
SP+3xDWRR, 8xSP, SP+7xDWRR,
2xSP+6xDWRR,
 Shaping per class
 Buffer size setting per class
 Yellow/Green threshold per class
 Egress port shaping
ETH OAM
 802.1ag Service OAM (CC/LB/LT)
 Y.1731 PM (LM/DM)
Equipment/traffic protection
STP/RSTP, G.8032v2 ERPS (Ethernet Ring)
Traffic aggregation over the air
802.1AX, 1:1 LACP redundancy; RTA load
balancing based on L2 (MAC, VID, TPID, port) or L3
(IP source and destination, both TCP/UDP port
numbers), frame ordering preserved; maximum
speed per stream is equal to single modem speed;
Physical RTA: maximum speed per stream equal
to combined capacity minus a small overhead
Synchronous Ethernet
Supported (optional clock module required)
TDM PWE
RFC4533 SAToP (MEF8)
Other
Link Loss Forwarding, Mirror/Monitor, Broadcast
Storm Control, L2 Filter, Port Isolation
