Table A-4. Syslog Severity Level Descriptions
A.8 MIB Enhancements
The following subsections describe MIB enhancements that have been
provided in firmware revision 2.01.
A.8.1 802.1p and 802.1Q MIB
Support for portions of the IETF 802.1p (priority) and 802.1Q (VLANs)
MIBs has been added.
•
IEEE 802.1p MIB - The IEEE 802.1p MIB is an extension to the
Bridge MIB defined by RFC 1493. This extension is used to manage
priority and multicast filtering as defined by IEEE 802.1D-1998. The
ELS100-24 switch supports only the portion of this MIB that is used
to manage traffic classification and priority configuration.
•
IEEE 802.1Q MIB - The IEEE 802.1Q MIB is an extension to the
Bridge MIB defined by RFC 1493. This extension is used to manage
802.1Q tagged VLANs as defined by IEEE 802.1Q-1998. The
ELS100-24 supports only the portion of this MIB that is relevant to its
capabilities.
A.8.2 Interfaces MIB: RFC 2233
RFC 2233 defines extensions to the Interfaces group of MIB-II. The 2.01
firmware revision for the ELS100-24 switch adds support for only a portion
of these extensions, specifically the Stack Table. This table is used to
map the physical ports of a switch with the logical trunk group to which
they belong.
