Management
You may experience slow performance (response time) when you
perform a walk of the a3Com.29 MIB, particularly when you request
the following fields:
a3ComBridgePortAddressBridgeIndex
a3ComBridgePortAddressPortIndex
Performing a walk of this MIB may also affect the performance of the
Administration Console interface and other management functions.
The 36-port 10/100BASE-TX Desktop Switching Modules (Model
Numbers 3CB9LF36RL and 3CB9LF36TL) support RMON groups 1, 2,
3, and 9.
Web-based
Management
If you use Netscape as your browser, you must install the Help files on
an external server, not on a local PC. For instructions on how to install
and configure Help for the Netscape browser, see “Documentation
Changes” later in this chapter. (29490)
SNMP
The MIB object a3ComSysEthernetPortCount returns a value that is
one (1) greater than the combined number of front panel ports and
backplane ports.
Do not configure or enable SNMP trap destinations from the
Administration Console with the
snmp trap addModify
command
on switch fabric modules or interface modules. Only configure and
enable SNMP trap destinations on the EME with the
set trap_destination
command. See “Documentation Changes” in
Chapter 3, “Release Issues” of the
CoreBuilder 9000 Release Notes for
Management Modules
for information about how to do this. (29770)
There is no SNMP support for creating or deleting trunks.
To prevent timeouts of SNMP requests, 3Com recommends that you
increase the default timeout for the network management station.
The value returned by ifType for backplane interfaces (117) are
specified as defined by the Internet Assigned Numbers Authority
(IANA) and not as specified in RFC 1213 or RFC 1573.
Ethernet
The 36-port 10/100BASE-TX Desktop Switching Modules (Model
Numbers 3CB9LF36RL and 3CB9LF36TL) are the only modules that
currently support PACE
®
. Although you can change the PaceAccess
setting to
enable
on other modules, they do not currently support
PACE and the setting actually remains disabled.
