506 | Port Monitoring

Table 27-1 lists the maximum number of monitoring sessions per system. For the C-Series and S-Series,
the total number of sessions is derived by consuming a unique destination port in each session, in each
port-pipe.
Port Monitoring on E-Series
Both the E-Series TeraScale and E-Series ExaScale support the following.
• FTOS supports one destination (MG) port per monitoring session. The same destination port (MG) can
be used in another monitoring session.
• One destination (MG) port can monitor up to 28 source (MD) ports.
• A port cannot be defined as both a source (MD) and a destination (MG) port (Message 1).
E-Series TeraScale
The E-Series TeraScale system supports 1 monitoring session per port-pipe. E-Series TeraScale supports a
maximum of 28 port pipes.
On the E-Series TeraScale, FTOS supports a single source-destination statement in a monitor session
(Message 2). E-Series TeraScale supports only one source and one destination port per port-pipe
(Message 3). Therefore, the E-Series TeraScale supports as many monitoring sessions as there are
port-pipes in the system.

Note: On the C-Series and S-Series, there is no limit to the number of monitoring sessions per system,
provided that there are only 4 destination ports per port-pipe. If each monitoring session has a unique
destination port, then the maximum number of session is 4 per port-pipe.
Message 1 Cannot define source (MD) and destination (MG) on same port
% Error: MD port is already being monitored.
Message 2 Multiple Source-Destination Statements Error Message on E-Series TeraScale
% Error: Remove existing monitor configuration.
