Table 76. RPM over VLT Scenarios (continued)
Scenario RPM Restriction Recommended Solution
The packet analyzer is connected to the
VLT device through the orphan port..
Mirroring using Intermediate VLT device
— In this scenario, the VLT device acts
as the intermediate device in remote
mirroring. The TOR switch contains the
source-RPM configurations that enable
mirroring of the VLT lag (of the TOR
switch) to any orphan port in the VLT
device. The packet analyzer is connected
through the VLT device, but not directly
to the VLT device.
No restrictions apply None.
Mirroring Orphan Ports across VLT
Devices — In this scenario, an orphan
port on the primary VLT device is
mirrored to another orphan port on the
secondary VLT device through the ICL
LAG. The port analyzer is connected to
the secondary VLT device.
No restrictions apply to the RPM
session. The following example
shows the configuration on the
primary VLT device:source orphan
port destination remote
vlan direction rx/tx/both.The
following example shows the
configuration on the secondary
VLT device:source remote vlan
destination orphan port.
None.
Mirroring VLT LAG across VLT Peers
— In this scenario, the VLT LAG on
the primary VLT peer is mirrored to
an orphan port on the secondary VLT
peer through the ICL LAG. The packet
analyzer is connected to the secondary
VLT peer.
No restrictions apply to the RPM
session. The following example
shows the configuration on the
primary VLT device:source VLT
LAG destination remote
vlan direction rx/tx/both.The
following example shows the
configuration on the secondary
VLT device:source remote vlan
destination orphan port.
None
Mirroring member port of ICL LAG to
Orphan Port of peer vlt device— In
this scenario, a member port of the ICL
LAG or a member port of the VLT LAG
is mirrored to an orphan port on the
peer VLT device. The packet analyzer is
connected to the peer VLT device.
The bandwidth of the VLTi link is
unnecessarily used by mirrored traffic if
max rate limit value is configured in the
RPM mirror session.
None.
Mirroring member port of ICL LAG to
VLT LAG — In this scenario, a member
port of the ICL LAG is mirrored to the
VLT LAG on the same VLT device. The
packet analyzer is connected to the TOR
switch.
No restrictions apply. The bandwidth of
the VLTi link is unnecessarily used by
mirrored traffic if max rate limit value is
configured in the RPM mirror session.
If you want to mirror traffic in the TOR
locally, use local Port mirroring session
instead of RPM.
Mirroring with a VLAN as source and
destination — If the members of the
source and destination VLANs are same
in a single monitoring session.
No restrictions apply. None.
Mirroring with an interface or LAG as
source and destination --- If the source
and destination interface or LAG of a
monitor session are same.
No restrictions apply. None.
