RPM on VLT Scenarios

Scenario 1

Mirror VLTi member ports traffic to a VLT port-channel. The packet analyzer connects to the ToR switch.

Scenario 1

Configs on VLTPeer1 device

Monitor session configs:

monitor session 1 type rpm-source
 destination remote-vlan 100
 source interface ethernet1/1/1 //VLTi member port
 source interface ethernet1/1/2 //VLTi member port
 no shut

RSPAN-VLAN:

interface vlan100
 no shutdown
 remote-span

Config on VLT port-channel:

interface port-channel1
 no shutdown
 switchport mode trunk
 switchport access vlan 1
 switchport trunk allowed vlan 100
 vlt-port-channel 1


ToR switch configs:

interface vlan100
 no shutdown

mac access-list rspan
 seq 10 permit any any capture session 1 vlan 100
!

Connect port channel to VLT:

interface port-channel 1
 no shutdown
 switchport mode trunk
 switchport access vlan 1
 switchport trunk allowed vlan 100
 mac access-group rspan in
!


monitor session 1
 destination interface ethernet1/1/26:1
 flow-based enable
 source interface port-channel1 rx
 no shut
!

Connect port to packet analyzer:

interface ethernet 1/1/26:1
 no shutdown
 no switchport
 flowcontrol receive on
!
NOTE:
  • An access-list can not be applied on the member ports of a port-channel and flow based monitor seession is not applicable to VLTi member ports.
  • In OS10, in the mirrored traffic, the RSPAN vlan tag is not stripped off or removed.

Scenario 2

Mirror orphan port traffic to a VLT port-channel. The packet analyzer connects to the ToR switch.

Scenario 2

Configs on VLTPeer1

interface vlan 100
 no shutdown
 remote-span

mac access-list rspan
 seq 10 permit any any capture session 1 vlan 10
