Port-Based Traffic Separation 

B-1 

RIC-155 supports separation between Ethernet management and user traffic. 
There are two traffic separation modes: port-based and port-based/VLAN-based. 
The traffic separation mode depends on the forwarding mode of the internal 
bridge: 
•  Filter – frames are received with VLAN tag or untagged, the bridge learns the 

source address of the incoming frames, performs the bridging according to the 
MAC address only. Traffic separation is port-based. 

•  Filter Tagged – the bridge separates management traffic from the user traffic 

by the tags assigned to the frames. The bridge operation complies with the 
relevant parts of IEEE 802.1Q. Traffic separation is port-based/VLAN-based. 

Port-based traffic separation is achieved by setting the physical port access to 
None

, MNG only (Ethernet Management only) or All. 

When the physical port access is set to None, only the 10/100BaseT data port is 
connected to the uplink port (

). In this case, the local RIC-155 cannot be 

managed from either the local DATA or MNG port. However, the remote RIC-155 
unit can be managed via the NMS connected to the local DATA port, and the 
remote unit can manage the local unit. 

 

Setting the physical port access to MNG only, disconnects the local DATA port 
from the local CPU, preventing the local RIC-155 from being managed via the 
DATA port, but allowing management via the remote DATA port. At the same 
time, both local and remote RIC-155s can be managed via the MNG port.
