28COREBUILDER 6000 EXTENDED SWITCHING SOFTWARE REVISION 8.2.3

■Performing a manual nvdata restore restores conﬁgurations to slots even if the conﬁgurations have been speciﬁed not to restore.

When you restore NV data, the system proposes a method of restoration based on restoration rules. You are prompted to load the proposal. Entering yes restores the system NV data as proposed. Entering no displays the saved conﬁguration for you to load manually.

■When you install software from an unreachable device using the SNMP lpsFt MIB, the system reports the incorrect status “statusFileNotFound”, rather than the correct status “statusRemoteUnreachable”.

■When you install software using the SNMP lpsFt MIB and you specify an invalid Username/Password pair, the system reports the incorrect status ”statusFileNotFound”, rather than the correct status “statusUserAuthFailed”.

■When you install software using the SNMP lpsFt MIB, the installation fails unless you specify a user password.

■If you are upgrading from system software revision 8.0.2, and you have an out-of-band Ethernet connection, 3Com recommends you remove the out-of-band Ethernet connection before rebooting the system. The connection may be reestablished after rebooting.

■Under certain network conditions involving errored source routed frames, it is possible for the system to reset with a panic line 55 or line 78.

SNMP MIB Files SNMP MIB ﬁles are shipped with the CoreBuilder 6000 system software as ASN.1 ﬁles on one of the software diskettes. Copies of ASN.1 ﬁles are provided for each of the compilers described in “Compiler Support.”

Supported Versions The SNMP MIB ﬁle names and the currently supported version of each MIB are listed here:

■bridge.mib — Bridge MIB, RFC 1493

■ethernet.mib — Ethernet MIB, RFC 1398

■fddiSmt7.mib — FDDI SMT 7.3 MIB, RFC 1512

■ﬁlter.mib

■if.mib — If MIB, RFC 1573 ■ lpsFt.mib
