15.2.1 General
In general the management plane can be configured using CLI (see separated software manual). In par-
ticular, for management purpose, the LAN interfaces can be configured as follow:
• Disable - the management is not transported for that LAN
• Local Access Only - LAN is dedicated to the management and it allows to reach the local CPU only
• In Band - LAN is configured to transport both management and data: management is differentiated
by dedicated VLan
• Drop Node - LAN is dedicated to the management and it is possible to access to both local CPU and
the rest of the network.
These management configurations are shown in the following paragraphs in examples where only LAN1
and LAN2 are employed but all the ports can be used with the limit of the bitrate allowed by the media
(LAN1 and LAN2 are optical with bitrate 2.5Gbps and LAN3 and LAN4 are electrical with bitrate 1Gbps).
15.2.2 ALFOplus2 - 1NE - InBand
In this configuration the management plane transport is shared with the data plane (see Fig.72). The dif-
ferentiation is obtained by managing different VLANs. A VLAN dedicated to the management shall be de-
fined (VLAN
mng
) and configured by the user.
Within "InBand context" it shall be possible to:
• Define which ports participate to the VLAN
mng
and the port connectivity scheme to obtain the de-
sired reachability (local only or also remote)
• In particular it shall be possible to dedicate a LAN to the management only (in this case untagged
management frames at this interface shall be supported, see "Drop Node" configuration)
• Configure the priority of management VLAN (PCP) and ToS.

shows an example of LAN1, P, TRX Port as member of the VLAN
mng
.
