Important Points to Remember
• On the Port Monitoring is supported on TeraScale and ExaScale platforms.
• Port Monitoring is supported on physical ports only. Logical interfaces, such as Port Channels and
VLANs, are not supported.
• FTOS supports as many monitor sessions on a system as the number of port-pipes.
• The monitoring (destination, “MG”) and monitored (source, “MD”) ports must be on the same
switch.
• A monitoring port can monitor any physical port in the chassis.
• Only one MG and one MD may be in a single port-pipe.
• A monitoring port can monitor more than one port.
• More than one monitored port can have the same destination monitoring port.
• FTOS on the S-Series supports multiple source ports to be monitored by a single destination port
in one monitor session.
• On the S-Series, one monitor session can have only one MG port. There is no restriction on the
number of source ports, or destination ports on the chassis.
