Configure VLAN-Based Mirroring in a Multi-Tenant Architecture

Before you begin

VLAN-based mirroring applies only to VLAN-based tenants and not to BD (bridge domain)-based tenants.

Procedure

  1. Run the following commands to configure access control list applications on Ethernet or port channel and VLAN or virtual Ethernet: 
    efa tenant epg create --name <epg-name> --tenant <tenant-name>

            --switchport --switchport-mode trunk –ctag-range <ctag-range>
            --port <mirror-source-port-list> --po <mirror-source-po-list>

            --pp-mac-acl-in <acl-name> --pp-mac-acl-out <acl-name>
            --pp-ip-acl-in <acl-name> --pp-ip-acl-out <acl-name>

            --np-mac-acl-in <ctag:acl-name> --np-mac-acl-out <ctag:acl-name>
            --np-ip-acl-in <ctag:acl-name> --np-ip-acl-out <ctag:acl-name>
  2. Run the following commands to configure a mirror session: 
    efa tenant service mirror session create –name <session-name> --tenant <tenant-name>

            --source {<device-ip>,<eth | po | vlan>,<if-name>}
            --type {<source-device-ip>,<eth | po | vlan>,<source-if-name>:<port-based | flow-based>}

            --destination {<source-device-ip>,<eth | po | vlan>,<source-if-name> :
                        <destination-device-ip>,<eth | po | vlan>,<destination-if-name}
            --destination-type {<source-device-ip>,< eth | po | vlan>,<source-if-name>:<span>}

            --direction {<source-device-ip>,< eth | po | vlan>,<source-if-name> : <tx | rx | both>}
