SNMP. The SNMP agent embedded in the S4224 is capable of version 1, 2c, or v3 support to access all management information from the device. The community strings for v1 and v2c and the USM/VACM for SNMPv3 are supported.
Page 67 Transition Networks S4224 Web User Guide SNMPv3 Simple Network Management Protocol Version 3 (SNMPv3) is an interoperable standards-based protocol for network management. SNMPv3 provides secure access to devices by a combination of authenticating and encrypting packets over the network. Although SNMPv3 makes no changes to the protocol aside from the addition of cryptographic security, its developers have managed to make things look much different by introducing new textual conventions, concepts, and terminology.
Page 68 Note: the concept of SNMP communities that was introduced in SNMPv2 is not relevant to SNMPv3, and has been replaced by SNMP groups/users. However, you can configure an S4224 to respond to both SNMPv2 and SNMPv3 commands. If both SNMPv2 and SNMPv3 are to be used, you must configure SNMP communities and SNMP groups and users.

Page 306: Ethernet Services Application Example
Transition Networks S4224 Web User Guide Ethernet Services Application Example E-Line services are typically used to replace TDM private lines and use two dedicated UNI ports. It is the most common type of Ethernet Service type. The transport-oriented Ethernet Private Line service provides an interconnection between switching or routing equipment in a private data network.
Page 307 Transition Networks S4224 Web User Guide Subscribers with multiple sites that need to be on the same LAN would configure an E-LAN Service. In an Ethernet Private LAN service CE-VLAN ID and Class of Service preservation applies so typically no coordination with a Service Provider is needed.
Page 308 Transition Networks S4224 Web User Guide Note: MAC learning is enabled for EVCs with more than two ports so that source addresses are learned for frames matching the EVC. An Ethernet Private Tree service can give subscribers the opportunity to interconnect multiple sites to provide services other than those resembling a LAN.

MD5 is an authentication protocol; one of two cryptography methods used for S4224 user authentication. MD5 is a widely used cryptographic hash function with a 128-bit hash value. Specified in RFC 1321, MD5 is used in a wide range of security applications, and is also commonly used to check file integrity.
Page 652 MEPs. A MIP does not initiate proactive or diagnostic OAM frames. See also “MEP”. Mirroring For debugging network problems or monitoring network traffic, the S4224 can be configured to mirror frames from multiple ports to a mirror port. (In this context, mirroring a frame is the same as copying the frame.) Both incoming (source) and outgoing (destination) frames can be mirrored to the mirror port.
