Dell(conf)#
In the following example, the host and server are exchanging trac 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 congured to only monitor trac received on tengigabitethernet 1/1 (host-originated
trac).
Figure 29. 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 conguration; the Dell Networking OS
permits a limited set of commands for monitoring ports. You can display these commands using the
? command.
• A monitoring port may not be a member of a VLAN.
• There may only be one destination port in a monitoring session.
• A source port (MD) can only be monitored by one destination port (MG). If you try to assign a monitored port to more than one
monitoring port, the following message displays:
Dell(conf)#mon ses 1
Dell(conf-mon-sess-1)#source tengig 0/1 destination tengig 0/33 direction both
Dell(conf-mon-sess-1)#do show monitor session
