Figure 27-1 illustrates a possible port monitoring configuration on the E-Series.
Figure 27-1. Port Monitoring Configurations on the E-Series
E-Series ExaScale
FTOS on E-Series ExaScale supports a single destination (MG) port monitoring multiple multiple source
(MD) ports in one monitor session. One monitor session can have only one destination (MG) port. The
same destination (MG) port can be uses with multiple monitoring sessions.
There is no restriction on the number of source (MD) or destination (MG) ports on the chassis because
there is no port-pipe restriction on the E-Series ExaScale system.
Port Monitoring on C-Series and S-Series
The C-Series and S-Series support multiple source-destination statements in a monitor session, but there
may only be one destination port in a monitoring session (Message 4).
The number of source ports FTOS allows within a port-pipe is equal to the number of physical ports in the
port-pipe (n). However, n number of ports may only have four different destination ports (Message 5).
Message 3 One Source/Destination Port per Port-pipe Error Message on E-Series TeraScale
% Error: Some port from this port pipe is already configured as MD.
% Error: Some port from this port pipe is already configured as MG.
Message 4 One Destination Port in a Monitoring Session Error Message on C-Series and S-Series
% Error: Only one MG port is allowed in a session.
