Users Guide

• Destination port (MG) can be a physical interface or port-channel interface.
• A Port monitoring session can have multiple source statements.
• Range command is supported in the source statement, where we can specify a range of interfaces of
(Physical, Port Channel or VLAN) types.
• One Destination Port (MG) can be used in multiple sessions.
• There can be a maximum of 128 source ports in a Port Monitoring session.
• Flow based monitoring is supported for all type of source interfaces.
• Source port (MD) can be a VLAN, where the VLAN traffic received on that port pipe where its members
are present is monitored
• Single MD can be monitored on max. of 4 MG ports.
Port Monitoring
Port monitoring is supported on both physical and logical interfaces, such as VLAN and port-channel
interfaces. The source port (MD) with monitored traffic and the destination ports (MG) to which an analyzer
can be attached must be on the same switch. You can configure up to 128 source ports in a monitoring
session. Only one destination port is supported in a monitoring session. The platform supports multiple
source-destination statements in a single monitor session.
The maximum number of source ports that can be supported in a session is 128.
The maximum number of destination ports that can be supported depends on the port mirroring directions as
follows:
• 4 per port pipe, if the four destination ports mirror in one direction, either rx or tx.
• 2 per port pipe, if the two destination ports mirror in bidirection.
• 3 per port pipe, if one of the destination port mirrors bidirection and the other two ports mirror in one
direction (either rx or tx).
In the following examples, ports Te 1/1/1, Te 1/1/2, Te 1/1/3, and Te 1/1/4 all belong to the same pipeline.
They are pointing to four different destinations: Te 1/4/1, Te 1/4/2, Te 1/4/3, and Te 1/4/4. If you attempt to
configure another destination (to create 5 MG port), the system displays an error message.

Dell(conf)#mon ses 300
Dell(conf-mon-sess-300)#source TenGig 1/17/1 destination TenGig 1/4/1 direction tx
