36 Port Monitoring The port monitoring feature allows you to monitor network traffic by forwarding a copy of each incoming or outgoing packet from one port to another port. The commands in this chapter are generally supported on the C-Series, E-Series, S-Series, Z-Series, and S4810. Important Points to Remember • On the E-Series, port monitoring is supported on TeraScale and ExaScale platforms. • Port monitoring is supported on physical ports only. Logical interfaces, such as Port Channels and virtual local area networks (VLANs), are not supported. • The Dell Force10 operating software (FTOS) supports as many monitor sessions on a system as the number of port-pipes. • You can only configure a SONET port as a monitored port. • The monitoring (destination, "MG") and monitored (source, "MD") ports must be on the same switch. • In general, a monitoring port should have no ip address and no shutdown as the only configuration; FTOS permits a limited set of commands for monitoring ports; display them using the ? command. A monitoring port also may not be a member of a VLAN. • 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. NOTE: The monitoring port should not be a part of any other configuration. description Enter a description of this monitoring session.
