47 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. Important Points to Remember ● Port monitoring is supported on physical ports and logical interfaces, such as port channels and virtual local area networks (VLANs). ● 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; Dell Networking OS 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 total of 4 MG may be configured in a single port-pipe. ● MG and MD ports can be reside anywhere across a port-pipe. ● The Dell Networking OS supports multiple source ports to be monitored by a single destination port in one monitor session. ● One monitor session can have only one MG port. ● PE Gigabit Ethernet (peGigE) ports can be added as source ports only. You cannot add cascade ports as destination ports. NOTE: The monitoring port should not be a part of any other configuration.
