Table 2. RPM on VLT scenarios
Scenario Recommendation
Mirror an orphan port or VLT LAG or VLTi member port to VLT
LAG. The packet analyzer is connected to the TOR switch.
The following is an example of recommended conguration on the
peer VLT device:
1 Create RPM VLAN
!
interface vlan 100
no shutdown
remote-span
!
2 Create an L2 ACL for the RPM VLAN - RPM session and
attach it to VLTi LAG interface.
!
mac access-list rpm
seq 10 permit any any capture session 10
vlan 100
!
interface ethernet 1/1/1
no shutdown
switchport access vlan 1
mac access-group rpm in
!
3 Create a ow based RPM session on the peer VLT device to
monitor the VLTi LAG interface as source.
!
monitor session 10 type rpm-source
destination remote-vlan 100
flow-based enable
source interface ethernet1/1/1 (ICL lag
member)
!
Mirror a VLAN with VLTi LAG as member to any orphan port on the
same VLT device. The packet analyzer is connected to the local VLT
device through the orphan port.
The following is an example of recommended conguration on the
VLT device:
1 Create an L2 ACL for the local session and attach it to the
VLTi LAG interface.
!
mac access-list local
seq 10 permit any any capture session 10
!
interface ethernet 1/1/1
no shutdown
switchport access vlan 1
mac access-group local 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.
