Session and VLAN requirements
RPM requires the following:
Source session, such as monitored ports on dierent source devices.
Reserved tagged VLAN for transporting monitored trac congured on source, intermediate, and destination devices.
Destination session, where destination ports connect to analyzers on destination devices.
Congure 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.
Consider the following when conguring a RPM session:
A remote port monitoring session mirrors monitored trac by prexing the reserved VLAN tag to monitored packets to transmit using
the reserved VLAN.
The source address, destination address, and original VLAN ID of the mirrored packet are prexed 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.
Reserved L2 VLAN
MAC address learning in the reserved VLAN is automatically disabled.
There is no restriction on the VLAN IDs used for the reserved remote monitoring VLAN. Valid VLAN IDs are from 2 to 4093. The default
VLAN ID is not supported.
In monitored trac, if the device has a L3 VLAN congured, packets that have the same destination MAC address as an intermediate
or destination device in the path the reserved VLAN uses to transport the mirrored trac are dropped by the device that receives the
trac .
Source session
Congure physical ports and port-channels as sources in remote port monitoring and use them in the same source session. You can use
both L2, congured with the switchport command, and L3 ports as source ports. Optionally, congure one or more source VLANs
to congure the VLAN trac to be monitored on source ports.
