Optical Ethernet-Private Line (OE-PL) service using 2x1000 SX/LX
OPE circuit packs
OPTera Metro 3500 allows you to provision 2xGigE circuit packs in a
point-to-point configuration using only SONET interfaces. You first use the
ED-SYS TL1 command to specify 2xGigE point-to-point mode for each shelf
involved in the configuration. When a 2xGigE circuit pack is provisioned on
the shelf (either manually or by installing the circuit pack in a valid and
unprovisioned slot), the circuit pack is automatically configured with the data
parameters required to enable point-to-point mode. The point-to-point
configuration is established by provisioning a Resilient Packet Ring (RPR)
cross-connect between the two circuit packs in point-to-point mode across a
ring (UPSR or BLSR). You can provision the RPR cross-connect through TL1
or through Site Manager.
The following lists the data parameters of a 2xGigE circuit pack that are
auto-provisioned when point-to-point mode is enabled:
• The CPU port of the circuit pack is set to Optical Ethernet layer 2 (OE/L2)
mode, configured with a default gateway address of 0.0.0.0, and
configured with an IP address of 10.a.b.c., where a.b.c. are the three least
significant bytes of the CPU port media access control (MAC) address
• LAN port 1 is set to OE/L2 mode and configured with an IP address of
10.a.b.c+1, where a.b.c. are the three least significant bytes of the CPU port
MAC address
• LAN port 1 is configured as a transparent user-to-network interface (UNI)
port with a transparent domain identifier (TDI) of 100
• TDI 100 on LAN port 1 is enabled and set to a connectivity type of
point-to-point
• LAN port 1 is enabled
• Token bucket is disabled on LAN port 1. Flow control is therefore based
on WAN bandwidth. See the OPTera Packet Edge System Planning Guide
(NTN465YG) for more information.
• The IEEE 802.1p priority mapping for TDI 100 on LAN port 1 is disabled,
that is, set to 0:0:0:0:0:0:0:0
Note 1: All other data parameters are unchanged from their default values.
In particular, auto-negotiation is enabled, pause frames are enabled, and
LAN port 2 is disabled. Refer to the OPTera Packet Edge System User
Guide (NTN465YG) for a list of default settings.
Note 2: A 2xGigE circuit pack auto-provisioned for point-to-point mode
operates in the same way as any other 2xGigE circuit pack. For example,
you can change any data parameter of the circuit pack using the existing
