RIC-155 Installation and Operation Manual Appendix B Traffic Separation
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:
• Tag stripping at the management and data ports
• Stacking at the uplink port.

Managing RIC-155 via Data Port
Figure B-10 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.
