Reference Guide

Scenario Recommendation
1 Create an L2 ACL for the local session and attach it to the
VLTi LAG interface.
!
mac access-list span
seq 10 permit any any capture session 10
!
interface ethernet 1/1/1
no shutdown
switchport access vlan 1
mac access-group span in
!
2 Create a ow based local session on the VLT device to
monitor VLTi LAG interface member (ethernet 1/1/1) as
source.
!
monitor session 10 type
destination interface ethernet 1/1/10 flow-
based enable
source interface ethernet1/1/1
no shut
!
Mirror a VLAN with VLTi LAG as member to VLT LAG on the same
VLT device. The packet analyzer is connected to the TOR switch.
—
Mirror VLT LAG of TOR, or any port in the TOR to any orphan port
in the VLT device. Congure VLT nodes as intermediate device. The
packet analyzer is connected to the TOR switch.
—
Mirror VLT LAG to any orphan port on the same VLT device. The
packet analyzer is connected to the local VLT device through the
orphan port.
If the packet analyzer is directly connected to the VLT peer in
which the source session is congured, use local port monitoring
instead of RPM.
Mirror an orphan port in primary VLT device to any orphan port on
secondary VLT device through VLTi. The packet analyzer is
connected to the secondary VLT device through the orphan port. In
this case, the mirroring packets are duplicated.
—
Mirror VLT LAG of the primary VLT device to any orphan port on
secondary VLT device through VLTi. The packet analyzer is
connected to the secondary VLT device through the orphan port.
—
Mirror a member port of VLTi LAG or VLT LAG to any orphan port
in the same device. The packet analyzer is connected to the local
VLT device through the orphan port.
If the packet analyzer is directly connected to the VLT peer in
which the source session is congured, use local port monitoring
instead of RPM.
Mirror a member port of VLTi LAG to VLT LAG on the same VLT
device. The packet analyzer is connected to the TOR switch.
—
Mirror VLT LAG or VLT member port as part of source VLAN and
destination VLAN. The packet analyzer is connected to the TOR
switch.
