Interfaces
These release notes accompany Release 4.1R2 of the BXOS software. They briefly
describe the hardware and software features, and identify the outstanding issues.
The BXOS software runs on the BX7000 Multi-Access Gateway.
The following are a list of features for the BX7000 Multi-Access Gateway and the
BXOS Release 4.1R2. Following the description is the title of the manual to consult

Support for IEEE 802.1ah OAM functionality on all Ethernet
interfaces—Ethernet interfaces support the IEEE 802.1ah standard for
Operation, Administration, and Management (OAM). The BXOS software
supports IEEE 802.3ah discovery and monitoring, remote fault detection, and
remote loopback. To enable IEEE 802.1ah support on the Ethernet interface,
include the interface statement at the [edit protocols oam-ethernet
link-fault-management]
Support for IEEE 802.1ag OAM functionality on all Ethernet
interfaces—Ethernet interfaces support the IEEE 802.1ag standard for OAM.
The IEEE 802.1ag specification provides Ethernet connectivity-fault
management (CFM), which is the standard for Layer 2 ping, Layer 2 traceroute,
and the end-to-end connectivity check of the Ethernet network. To enable IEEE
802.1ag support on the Ethernet interface, include the interface statement at
the [edit protocols oam-ethernet connectivity-fault-management] hierarchy level.
