In the following example, the host and server are exchanging traffic which passes through the uplink
interface 1/1. Port 1/1 is the monitored port and port 1/42 is the destination port, which is configured to
only monitor traffic received on tengigabitethernet 1/1 (host-originated traffic).
Figure 28. Port Monitoring Example
Important Points to Remember
• Port monitoring is supported on physical ports only; virtual local area network (VLAN) and port-
channel interfaces do not support port monitoring.
• The monitored (the source, [MD]) and monitoring ports (the destination, [MG]) must be on the same
switch.
• The monitored (source) interface must be a server-facing interface in the format slot/port, where the
valid slot numbers are 0 or 1 and server-facing port numbers are from 1 to 32.
• The destination interface must be an uplink port (ports 33 to 56).
• In general, a monitoring port should have no ip address and no shutdown as the only
configuration; the Dell Networking OS permits a limited set of commands for monitoring ports. You
can display these commands using the ? command.
