Quidway® AR 28 Series 100 M Ethernet Line Module
Quidway® AR 28 Series 100 M Ethernet Line Module
Overview
The 10/100 M Ethernet electrical interface module and 100 M Ethernet optical interface module of
the AR28 router provide Fast Ethernet (FE) electrical and optical interfaces respectively, mainly for
communicating with the router and LAN.
At present, the AR28 router has two ordinary 10/100 M Ethernet electrical interface modules: 1-port
fast interface module and 2-port fast interface module (not supported by AR281* and AR2809/B
modules). It also has two optical interface modules: 1-port fast single-mode optical interface
module and 1-port fast multi-mode optical interface module.
Moreover, the AR28 router has a particular 8-port Ethernet layer-2 switching module. This module
is mainly used to implement the layer-2 switching function. Up to eight 10/100 Base-Tx Ethernet
ports can be provided on the router. It is applicable to the small-sized enterprise network, serving as
the switching/routing integrated equipment. It is connected with the PC and network device in the
enterprise directly, lowering the investment of enterprise. The features of layer-2 Ethernet port are
shown in the following:
Support layer-2 forwarding.
Support broadcast storm suppression ratio.
Support MAC address aging time.
Support dividing VLANs (802.1Q) based on port (in 8-/16-port).
Not support STP/MSTP/RSTP. So, avoid loopback in the case of networking.
Not support port aggregation.
