Figure 38-3. Number of Monitoring Ports on the C-Series and S-Series
In Figure 38-4, 0/25 and 0/26 belong to Port-pipe 1. This port-pipe again has the same restriction of only
four destination ports, new or used.
Figure 38-4. Number of Monitoring Ports on the C-Series and S-Series
A source port may only be monitored by one destination port (Message 6), but a destination port may
monitor more than one source port. Given these parameters, Figure 38-1 illustrates conceptually the
possible port monitoring configurations on the C-Series and S-Series.
Message 5 One Destination Port in a Monitoring Session Error Message on C-Series and S-Series
% Error: Exceeding max MG ports for this MD port pipe.
Message 6 One Destination Port per Source Port Error Message
% Error: MD port is already being monitored.
