Chapter 1 Overview of the ML-Series Card
Key ML-Series Features
Link Aggregation (FEC and POS)
The ML-Series offers Fast EtherChannel and POS channel link aggregation. Link aggregation groups
multiple ports into a larger logical port and provides resiliency during the failure of any individual ports.
The ML-Series supports a maximum of four Ethernet ports in Fast EtherChannel, and two SONET
virtual ports in POS channel. POS channel is only supported with LEX encapsulation.
Traffic flows map to individual ports based on MAC source address (SA)/destination address (DA) for
bridged packets and IP SA/DA for routed packets. There is no support for policing or class- based packet
priorities when link aggregation is configured.
RMON
The ML-Series card features RMON that allows network operators to monitor the health of the network
with an NMS. ONG RMON is recommended for the ML-100T-8. The ONG RMON contains the
statistics, history, alarms, and events MIB groups from the standard RMON MIB. The standard
Cisco IOS RMON is also available. A user can access RMON threshold provisioning through TL1 o r
CTC. For more information on RMON, refer to the “SNMP Remote Monitoring” section in “SNMP”
chapter of the Cisco ONS 15310-CL and Cisco ONS 15310-MA Reference Manual.
RPR
RPR is an emerging network architecture designed for metro fiber ring networks. This new MAC
protocol is designed to overcome the limitations of STP, RSTP, and SONET in packet-based networks.
RPR convergence times are comparable to SONET and much faster than STP or RSTP. RPR operates at
the Layer 2 level and is compatible with Ethernet and protected or unprotected SONET circuits.
SNMP
The Cisco ONS 15310-CL, the Cisco ONS 15310-MA, and the ML-Series c ards have SNMP agents and
support SNMP Version 1 (SNMPv1) and SNMP Version 2c (SNMPv2c) sets and traps. The Cisco ONS
15310-CL and the Cisco ONS 15310-MA accept, validate, and forward ge t/getNext/set requests to the
ML-Series through a proxy agent. Responses from the ML-Series are relayed by the Cisco ONS
15310-CL and the Cisco ONS 15310-MA to the requesting SNMP agents.
The ML-Series card SNMP support includes:
• STP traps from Bridge-MIB (RFC 1493)
• Authentication traps from RFC 1157
• Export of QoS statistics through the CISCO-PORT-QOS-MIB extension
For more information on how the ONS 15310-CL implements SNMP, refer to the “SNMP” chapter of
the Cisco ONS 15310-CL and Cisco ONS 15310-MA Reference Manual. For more information on
specific MIBs, refer to the Cisco SNMP Object Navigator at http://www.cisco.com.
