14.4.1 Appearance and functions
Appearance
Function
The OPCOM3500E-8EOS-FE is an 8-way electrical interface EOS service aggregation
card on the iTN2100.
Provide a 100 Mbit/s Ethernet electrical interface.
Support abstract of eight ways of Ethernet services from SDH signals, and aggregate
them into a way of Ethernet signals which can be output from the Ethernet electrical
interface on the front panel or transmitted to the switching card through the backplane.
In the reverse direction, it performs GFP or LAPS encapsulation of eight ways of
Ethernet signals from the switching card, maps them to SDH in N×VC12 level, and then
transmits them to the aggregation card through the backplane after time sequence
adjustment.
Support virtual cascading of input Ethernet services with N×VC12 bandwidth, and then
transmit them to the SDH network.
Support two Ethernet encapsulation modes: GFP and LAPS.
Support VCAT and LCAS.
Support loopback detection, automatical switchoff and recovery of Ethernet interfaces.
Support storm control over broadcast messages, unknown multicast messages, and DLF
messages.
Support interface isolation protection.
Support interface aggregation.
Support QoS and determine four output queues by priority.
Support 802.1Q VLAN, support 4K concurrent VLANs, and support QinQ.
Support 8k MAC addresses and 30 static MAC addresses.
Support enabling or disabling MAC address learning based on interfaces.
Support configurable aging time ranging from 0s to 3825s. By default, it is 300s.
Support interface-based non-linear rate limiting ranging from 62 Kbit/s to 100 Mbit/s.
Support transparently transmitting BPDU, LACP, and 802.1x management frames.
Support hot swapping.
14.4.2 Slots
The OPCOM3500E-8EOS-FE can be plugged into slots 1–5 and 8–12 on the iTN2100.
