CE
The E-LMI implementation on MX Series routers includes only the PE side of the
E-LMI protocol.
E-LMI interoperates with an OAM protocol, such as Connectivity Fault Management
(CFM), that runs within the provider network to collect OAM status. CFM runs at the
provider maintenance level (UNI-N to UNI-N with up MEPs at the UNI). E-LMI relies
on the CFM for end-to-end status of EVCs across CFM domains (SVLAN domain or
VPLS).
The E-LMI protocol relays the following information:
716
Configuring Ethernet Local Management Interface
UNI
Metro Ethernet Network
E-LMI
Notification to the CE of the addition/deletion of an EVC (active, not active, or
partially active)
Notification to the CE of the availability state of a configured EVC
Communication of UNI and EVC attributes to the CE:
UNI attributes:
UNI identifier (a user-configured name for UNI)
CE-VLAN ID/EVC map type (all-to-one bundling, service multiplexing
with bundling, or no bundling)
Bandwidth profile is not supported (including the following features):
CM (coupling mode)
CF (color flag)
CIR (committed Information rate)
CBR (committed burst size)
EIR (excess information rate)
EBS (excess burst size)
EVC attributes:
EVC reference ID
EVC status type (active, not active, or partially active)
UNI
CE
