Ethernet Link OAM Overview


� Operates on a single point-to-point link between 2 devices� Slow protocol using packets called OAMPDUs which are never forwarded� Provides 5 functions:

Remote failure indication – Inform peer device that receive path is down. Requires unidirectional operation support.Remote loopback – Puts device in a state such that all non-OAM packets are looped back. Normal forwarding is suspended. Statistics can be collected while testing link.Link monitoring – Event notification and link information. Also provides polling and response (but not writing) of 802.3ah MIBOAM discovery – Discovers OAM support and capabilities on peer deviceMib Variable Retrieval – Not Implemented

ME 3400G-2CSProduct Overview

January 2007


•2 Dual Purpose ports + 2 SFP only ports•Smaller footprint (approximately same as Catalyst 2940)•Wire-speed switch built with Cisco switching ASIC•Fixed AC only•Higher temperature range support: 0 ~ 50c•Supports both Fast Ethernet and Gigabit Ethernet SFP modules•Supports same Metro Software Images / Features as ME 3400-24TS and ME 3400G-12CS•Requires 12.2(35)SE (Fall ’06) or later release. Does not support earlier releases of ME 3400 Series software.

ME 3400 Series New Port types – UNI/NNI

� By default, all 10/100 ports are UNI ports� UNI ports are shut down by default

� By default, both SFP ports are NNI ports

UNI NNI


� UNI ports are shut down by default� UNI ports will not do local switching by default� For customers using multiple UNI ports on the same ME 3400, up to 8 UNI ports can be configured to do local switching

� UNI port will have Control Plane Security enable by default - control protocols can only be dropped or tunneled (i.e. VTP, CDP, BPDU, LACP, PAgP, DTP) – this offers protection agaist DoS attacks

� UNI port still processes 802.1x, UDLD and IGMP packets

� There can be maximum of 4 ports defined as NNI ports*

� NNI ports are up by default

� NNI ports can negotiate port speed and duplex

*METROIPACCESS image allows for unlimited numbers of NNI

ME 3400 Series Security Features-Overview

The Service Provider Challenge:•As Metro Ethernet networks continue to expand, one of the challenges a service provider has is to provide the same level of security as other access technologies. •Cisco ME 3400 Series Switches have been designed to offer a complete security solution. By dividing security into three categories and designing a comprehensive set of features for each:


Subscriber Security Switch Security Network SecurityUNI Default No Local Switching Control Plane Security UNI Default Port Down DHCP Snooping Port Security Access Control List IP Source Guard Storm Control 802.1x Dynamic ARP Inspection Configurable Per VLAN

MAC LearningConfiguration File Security

Private VLAN TACAS+/Radius VLAN 1 minimization
