...reference for building managed optical solutions with the
EM316LNXNM-OT.
11.1. Building an Optical Service Channel
There are two features included on the EM316LNXNM-OT for cluster support: Discovery Protocol and
Loop Management Protocol (LMP). Both protocols work with networks connected to the SFP ports on the
EM316LNXNM-OT. The RJ-45 port does not currently support management clustering.
11.1.1. Discovery Protocol
Discovery is a simple layer 2 protocol used to discover other NM cards on the same Optical Service
Channel (OSC) network. Each NM card multicasts layer 2 frames to announce its presence to other NM
cards connected via OSC ports. To see the list of discovered NM cards, use the "
show discovery
hosts
" command:
fiberdriver# show discovery hosts

Discovery is enabled by default.
Disable the discovery protocol using the "
no sys discovery
" command:
fiberdriver# configure terminal
fiberdriver(config)# no sys discovery
fiberdriver(config)#
The discovery protocol only discovers cards connected to the SFP ports. The copper RJ-45 Ethernet
network interface does not support discovery frames.
