Port Mirroring
SecureStack C3 Configuration Guide

•
On
switches
on
the
path
from
the
source
port
to
the
remote
destination,
egress
tagging
has
to
be
enabled
on
potential
egress
ports
for
the
mirror
VLAN.
With
the
introduction
of
remote
port
mirroring:
•
Configured
mirror
destination
ports
will
NOT
lose
their
switching
or
routing
properties
as
they
do
on
SecureStack
A2,
B2,
or
C2
products.
•
On
switches
where
the
mirror
VLAN
has
been
configured,
any
traffic
on
that
VLAN
will
be
flooded
on
the
VLAN.
It
will
never
be
unicast,
even
if
the
source
address
of
the
traffic
as
been
learned
on
the
switch.
Configuring SMON MIB Port Mirroring
Overview
SMON
port
mirroring
support
allows
you
to
redirect
traffic
on
ports
remotely
using
SMON
MIBs.
This
is
useful
for
troubleshooting
or
problem
solving
when
network
management
through
the
console
port,
telnet,
or
SSH
is
not
feasible.
Procedures
Perform
the
following
steps
to
configure
and
monitor
port
mirroring
using
SMON
MIB
objects.
To
c
reate
and
enable
a
port
mirroring
instance:
1.
Open
a
MIB
browser,
such
as
Netsight
MIB
Tools
2.
In
the
MIB
directory
tree,
navigate
to
the
portCopyEntry
folder
and
expand
it.
3.
Select
the
portCopyStatus
MIB.
4.
Enter
a
desired
source
and
target
port
in
the
Instance
field
using
the
format
source.target
.
For
example,
3.2
would
create
a
relationship
where
source
port
ge.1.3
would
be
mirrored
to
target
port
ge.1.2.
5.
Enter
MIB
option
4
(createAndGo)
and
perform
an
SNMP
Set
operation.
6.
(Optional)
Use
the
CLI
to
verify
the
port
mirroring
instance
has
been
created
and
enabled
as
shown
in
the
following
example:
C3(su)->show port mirroring
Port Mirroring
==============
Source Port = ge.1.3
Target Port = ge.1.2
Frames Mirrored = Rx and Tx
Port Mirroring status enabled
To
create
a
port
mirroring
instance
without
automatically
enabling
it:
1.
Complete
steps
1
‐
4
above.
2.
Enter
MIB
option
5
(createAndWait)
and
perform
an
SNMP
Set
operation.
3.
(Optional)
Use
the
CLI
to
verify
the
port
mirroring
instance
has
been
created
set
to
disabled
mode
as
shown
in
the
following
example:
C3(su)->show port mirroring
Note:
In order to configure a port mirroring relationship, both source and destination interfaces must
be enabled and operational (up).
