Appendix B Traffic Separation RIC-155Installation and Operation Manual

Local MNG Only

In the Local MNG Only port access mode, local data frames can reach the uplink port only. Local management frames can reach the host and uplink ports, and the remote management frames can reach the local uplink, host and data ports.

In the MNG Only access mode, the host port checks the source port of the incoming frames and drops those that do not originate from the management port.

See Managing RIC-155 via MNG Port for the application example.

B.3 Configuring for a Typical Application

Managing RIC-155 via MNG Port

Figure B-9shows two RIC-155 units managed via MNG port. In this application the local management frames are forwarded to the host and uplink ports, and the local data frames are sent to the uplink port only. Both management and data frames receive tags according to their source port (1 for management and 2 for data). The tags are received at egress from the uplink port. 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.
