Configuring for a Typical Application 

 

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 

 for the application example.

 shows 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.
