SEHI MIB Structure

SEHI management information base conﬁguration

IETF MIB Support

In addition to its proprietary features, the SEHI-22/24 and SEHI-32/34 currently support the following IETF MIB:

•RFC 1213 MIB for Network Management of TCP/IP-based Internets: MIB-II

SEHI MIB Structure

Cabletron’s newer intelligent devices — like the SEHI — organize MIB data into a series of “components.” A MIB component is a logical grouping of MIB data, and each group controls a deﬁned set of objects. For example, SEHI repeater information resides in its Repeater component; more generic device and port information resides in the SEHI Chassis MGR component.

The SEHI MIB consists of ﬁve components, each of which is described below. To see the names of the MIB components in your SEHI, bring up the Community Names application, or use any SNMP Get operation that will allow you to view the contents of the chCompTable.

The SEHI MIB consists of the following components:

SEHI Chassis MGR

The Chassis MGR MIB component contains most of the basic information about the SEHI, including: the SEHI’s MIB component information (in the chCompTable), device names, hardware revision numbers, MAC and IP addresses, the current time and date, and information related to redundancy, alarms, and TFTP download. The system, interfaces, at, ip, icmp, udp, and snmp groups from MIB-II are also included. The community names assigned to this MIB component provide the gateway that all SPMA applications use to access all information in the other components, even if those components have different
