CFM (Connectivity Fault Management) (Ether OAM)
Connectivity monitoring and failure management are available at the Layer 2 level by
performing continuity checks (CC), loopbacks, and linktraces.

In addition to the basic MIB-II, supports a wide range of MIBs including RMON.

Supports port mirroring to monitor and analyze traffic.

Support for SD memory cards

Hardware-based high-performance filtering processes
Partial specification of L2, L3, or L4 headers
L2-QoS (including IEEE 802.1p, bandwidth controls, and priority controls) and
IP-QoS (including Diff-Serv
Only the marking functionality is supported.
Clear audio in which VoIP packets are preferentially transmitted.
High reliability assured through exacting component selection and strict
design and testing standards
High-speed path switching
Standard functionality, such as link aggregation (IEEE 802.3ad) and
high-speed Spanning Tree Protocol (IEEE 802.1w and IEEE 802.1s), and
proprietary functionality, such as GSRP-aware and Autonomous Extensible
#
Ring Protocol (abbreviated hereafter to Ring Protocol), allow a redundant
high-reliability network to be built. Uplink redundancy, which can build
redundant configurations without using a Spanning Tree, is supported.
This Switch supports transit nodes only. For details about the Ring Protocol,
see 20 Description of the Ring Protocol.
UDLD prevents Spanning Tree loops and link aggregation frame loss.
The Layer 2 loop detection functionality helps prevent loops by detecting
improperly connected devices on the network.
