Example of Changing the Destination Port in a Monitoring Session

Example of Configuring Another Monitoring Session with a Previously Used Destination Port
FTOS(conf)#mon ses 300
FTOS(conf-mon-sess-300)#source gig 0/17 destination gig 0/4 direction tx
% Error: Exceeding max MG ports for this MD port pipe.

30 Gi 0/16 Gi 0/37 rx interface Port-based
300 Gi 0/17 Gi 0/1 tx interface Port-based
In the example below, 0/25 and 0/26 belong to Port-pipe 1. This port-pipe has the same restriction of only four destination
ports, new or used.

A source port may only be monitored by one destination port (% Error: Exceeding max MG ports for
this MD port pipe.), but a destination port may monitor more than one source port.
Given these parameters, the following illustration shows the possible port monitoring configurations on the S-Series.
