Chapter 17 CE-Series Ethernet Cards
CE-MR-6 Ethernet Card
Note
Priority queuing has no effect when flow control is enabled (default) on the CE-MR-6. When flow
control is enabled, a 6KB, single-priority, first-in first-out (FIFO) buffer fills, then a PAUSE frame is
sent. This results in the packet ordering priority becoming the responsibility of the external device,
which is buffering as a result of receiving the PAUSE flow-control frames.
Note
Priority queuing takes effect only when there is congestion at the egress POS. For example, priority
queuing has no effect when the CE-MR-6 card is provisioned with STS-3C circuits and the front-end is
100 Mbps. The STS-3c circuit has more data capacity than Fast Ethernet, so CE-MR-6 buffering is not
needed. Priority queuing only takes effect during buffering.
RMON and SNMP Support
The CE-MR-6 card features remote monitoring (RMON) that allows network operators to monitor the
health of the network with a network management system (NMS). The CE-MR-6 card uses
ONG RMON. ONG RMON contains statistics, history, alarms, and events MIB groups from the standard
RMON MIB as well as Simple Network Management Protocol (SNMP). A user can access RMON
threshold provisioning through TL1 or CTC. For RMON threshold provisioning with CTC, see the Cisco
ONS 15310 Procedure Guide and the Cisco ONS 15310 Troubleshooting Guide.
