Dell SmartFabric OS10 User Guide Release 10.5.3

RPM requires the following:

• Source session, such as monitored ports on different source devices.
• Reserved tagged VLAN for transporting monitored traffic configured on source, intermediate, and destination devices.
• Destination session, where destination ports connect to analyzers on destination devices.

Configure any network device with source and destination ports. Enable the network device to function in an intermediate transport session for a reserved VLAN for multiple remote port monitoring sessions. You can enable and disable individual monitoring sessions.

VLAN requirements when configuring an RPM session:

• A remote port monitoring session mirrors the monitored traffic by prefixing the reserved VLAN tag to the monitored packets to transmit using the reserved VLAN.
• The source address, destination address, and original VLAN ID of the mirrored packet are prefixed with the tagged VLAN header. Untagged source packets are tagged with the reserved VLAN ID.
• The member port of the reserved VLAN must have the MTU and IPMTU value as MAX+4 to hold the VLAN tag parameter.
• To associate with the source session, the reserved VLAN can have up to four member ports.
• To associate with the destination session, the reserved VLAN can have multiple member ports.
• The reserved VLAN cannot have untagged ports.
