Table 71. RPM over VLT Scenarios (continued)
Scenario RPM Restriction Recommended Solution
Mirroring an ICL LAG to Orphan Port —
In this scenario, the ICL LAG is mirrored
to any orphan port on the same VLT
device. The packet analyzer is connected
to the local VLT device through the
orphan port.
No restrictions apply. If the packet analyzer is directly
connected to the VLT device, use local
Port mirroring session instead of RPM.
Mirroring an ICL LAG to the VLT LAG —
In this scenario, the ICL LAG is mirrored
to the VLT LAG on the same VLT device.
Packet analyzer is connected to the
TOR.
No restrictions apply. None.
Mirroring VLT LAG to Orphan Port — In
this scenario, the VLT LAG is mirrored to
an orphan port on the same VLT device.
The packet analyzer is connected to the
VLT device through the orphan port..
No restrictions apply. If the packet analyzer is directly
connected to the VLT device, use local
Port mirroring session instead of RPM.
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
No restrictions apply. The bandwidth of
the VLTi link is unnecessarily used by
If you want to mirror traffic in the TOR
locally, use local Port mirroring session
instead of RPM.
