B-2 Packet Over SONET Module Installation and User Guide
SONET/SDH Support
This section lists the Synchronous Optical Network/Synchronous Digital Hierarchy
(SONET/SDH) related standards and SNMP MIBs that are supported for the PoS
modules.
Standards Supported for SONET/SDH
The Extreme Networks SONET/SDH implementation complies with the following
standards:
• GR-253-CORE, Synchronous Optical Network (SONET) Transport Systems: Common
Generic Criteria, Bellcore, Issue 2, Revision 2, January 1999.
• ANSI T1.105.02-1995, Synchronous Optical Network (SONET)—Payload Mappings,
American National Standards Institute, 1995.
• ITU-T G.707 (03/96), Network Node Interfaces for the Synchronous Digital Hierarchy
(SDH), March 1996.
MIBs Supported for SONET/SDH
A subset of RFC 2558, Definitions of Managed Objects for the SONET/SDH Interface Type,
has been implemented. The Virtual Tributary (VT) group and the Section/Line/Path
interval tables were not implemented. Read-only support (GET operations, but not SET
operations) has been implemented for the remainder of the MIB.
PPP Support
This section lists the PPP-related software standards and SNMP MIBs that are
supported for the PoS modules.
Standards Supported for PPP
In addition to the MIB support described above, the Extreme Networks PPP
implementation complies with the following standards:
• RFC 1661: The Point-to-Point Protocol
• RFC 1662: PPP in HDLC-like Framing
