Chapter 22 Configuring Frame Relay to ATM Network and Service Interworking
OAM Cells
OAM Cells
OAM cell processing:
•
F5 OAM loopback
• AIS
•
FERF
•
Cisco WAN switching Internal OAM
ATF Features
•
Interworking: ATM to Frame Relay connections
• Connection Statistics
•
Round Trip Delay measurements incorporated into the ForeSight algorithm
•
Frame Based GCRA (FGCRA). This is an enhancement of the Generic Cell Rate Algorithm
•
IBS (Initial Burst Size)
• cnfportq : 3 egress port queues are configurable CBR, VBR and VBR w/Foresight. (Queue Bin
numbers and algorithm types are NOT user selectable.)
•
BCM (Backward Congestion Messages)
• ILMI and associated configuration options and statistics
•
Loopback functions: tstdly , tstconseg , addrmtlp , addloclp
•
Selftest/ Background tests
•
OAM flows: AIS, FERF, OAM loopback
• End-to-end status updates (per FR/ATM interworking)
•
Annex G and associated configuration options and statistics
ATF Limitations
•
Priority Bumping is not supported across the interface shelves, but is supported across the routing
network.
•
Statistical Line Alarms per Software Functional Specification (that is, Bellcore standards).
•
Programmable Opti Class: although 4 connection classes are supported: CBR, VBR, VBR with
Foresight, ATF, and ATF with ForeSight. Configuration of egress port queues and BNI trunk queues
for these connection classes is available.
• Port loopback tstport
•
Test tstcon is not supported at BPX switch endpoints.
• Gateway terminated inter-domain connections
