You can designate monitoring of inbound and outbound traffic on:
■ Ports and static trunks: Allows monitoring of individual ports, groups
of contiguous ports, and static port trunks.
■ Static VLANs: Allows traffic monitoring on one static VLAN.
■ Meshed ports: Allows traffic monitoring on all ports configured for
meshing on the switch.
The switch monitors network activity by copying all traffic inbound and
outbound on the specified interfaces to the designated monitoring port, to
which a network analyzer can be attached.
Note VLANs, a switch mesh, and port trunks cannot be used as a monitoring port.
The switch can monitor static LACP trunks, but not dynamic LACP trunks.
It is possible, when monitoring multiple interfaces in networks with high
traffic levels, to copy more traffic to a monitor port than the link can support.
In this case, some packets may not be copied to the monitor port.
