Configuring for a Typical Application 

B-7 

The units are configured as follows: 
•  Local RIC-155: 

 

Forwarding – Filter Tagged 

 

Port Management Access – MNG Only 

 

Host Tagging – Untagged 

 

Management and data ports – Tag stripping is enabled 

 

uplink port – Stack. 

•  Remote RIC-155: 

 

Forwarding – Filter Tagged 

 

Port Management Access – None 

 

Host Tagging – Untagged 

 

Management and data ports – Tag stripping is enabled 

 

uplink port – Stack. 

 

When the forwarding mode is set to Filter Tagged or port access mode is set to 
MNG Only, the following parameters are enabled automatically:

 shows two RIC-155 units managed via data port. In this application the 

management and data frames are tagged by an external switch and sent to the 
data port. The Data port is configured to leave the incoming frames unchanged 

(tag stripping is disabled). At the egress from the data port, the management frames 
are forwarded to the host and uplink ports, and the data frames are sent to the 
uplink port only. The host port adds VID 1 to the management frames to ensure 
that they reach the management station when they are sent back. At the egress 
from the uplink port, no tags are added to the frames, because they arrive tagged.  
When the frames enter the remote uplink port their tags are checked against the 
remote VTU table and forwarded according to their tags: 1 to the host port and 2 
to the data port. The host port strips the VLAN tag of the management frames and 
forwards them to the CPU.
