Operating Considerations for Release 3.0.5 57
Operating
Considerations for
Release 3.0.5
This section describes operating considerations that apply to Layer 2
Switching Modules that operate with software Release 3.0.5.
System
■
After you enter an
nvdata reset
command (or initiate a trunk group
definition or deletion), there is a delay before the module initiates the
reset and returns to the Administration Console.
■
When you first insert and initialize a Gigabit Ethernet Layer 2
Switching Module, the switch fabric module generates the trap
sequence:
Link Up... Link Down... Link Up
. This is normal.
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 these release notes. (29490)
SNMP
■
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 MIB object a3ComSysEthernetPortCount returns a value that is
the combined number of front panel ports, the backplane ports, and
the management ports.
■
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
■
Although you can change the PaceAccess setting to
enable
, the
modules do not currently support PACE and the setting actually
remains disabled.
