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.

Note 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-10shows 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.
