Use either approach
You can configure multiple
source ports at a time in
system view, or you can
configure the source port in
specific port view. The
configurations in the two
views have the same effect.

When configuring local port mirroring, note that:
z You need to configure the source and destination ports for the local port mirroring to
take effect.
z The source port and the destination port cannot be a member port of an existing
mirroring group; besides, the destination port cannot be a member port of an
aggregation group or a port enabled with LACP or STP.
Configuring Remote Port Mirroring
An S5100-SI/EI series Ethernet switch can serve as a source switch, an intermediate
switch, or a destination switch in a remote port mirroring networking environment.
