802.1p PORT PRIORITY
The 802.1p port priority is used to assign a default priority to the frames received without priority
information in their tag header, map prioritized frames to the appropriate transmit queues, and
prioritize frames according to protocol type. The 802.1p port priority is part of the IEEE 802.1D
standard.
1.8
MANAGEMENT
Management of the module can be either in-band or out-of-band. In-band remote management is
possible through any SNMP-compliant Network Management Software, such as the Enterasys
Networks' NetSight™ management product. In-band management using Telnet and Enterasys
Networks' Webview™ is also provided. Out-of-band Local Management is provided through the
RJ45 COM port on the front panel using a VT100 terminal or a VT100 terminal emulator.
Local Management provides the ability to manage the devices. Refer to the Matrix C Series
Configuration Guide for more information.
1.9
SWITCHING OPTIONS
The devices provide 802.1Q switching between all of the front panel interfaces. In the 802.1Q
mode (the default mode of operation), the device functions as an 802.1D switch until you
configure VLANs. Up to 4094 VLANs can be configured. When VLANs are configured, the
backplane ports are automatically configured as Q-trunk ports.
IEEE 802.1Q switching allows migration to Virtual Network technologies without requiring the
replacement of existing equipment.
1.10 STANDARDS COMPATIBILITY
The C1H124-48 and C1G124-24 devices are fully compliant with the IEEE 802.3, 802.3u, 802.3x,
802.1D, and 802.1Q standards. The devices provide IEEE 802.1D Spanning Tree Algorithm
(STA) support to enhance the overall reliability of the network and protect against "loop"
conditions. The devices support a wide variety of industry standard MIBs including RFC 1213
(MIB II), RFC 1757 (RMON), and RFC 1493 (Bridge MIB). A full suite of Enterasys Networks
Enterprise MIBs provide a wide array of statistical information to enhance troubleshooting. For
information on how to extract and compile individual MIBs, contact Enterasys Networks. Refer to
the Release Notes for a complete list of supported MIBs.
