Operating
Considerations in
Release 3.0.5
This section describes operating considerations that apply to Multilayer
Switching Modules with software Release 3.0.5.
System
■
Modules can be staged in one chassis type then moved to a different
chassis type (For example, from a 16-slot CoreBuilder 9000 chassis to
a 7-slot Switch 4007 chassis). However, a module’s backplane port
trunking configuration (if there is any) may change; it depends on the
differences in the backplane port mapping scheme of each chassis and
the types of switch fabric modules that are installed.
■
Restoring the nonvolatile data configuration from one Switch 4007 to
another can result in duplicate Open Shortest Path First (OSPF) router
IDs and cause OSPF problems. Be sure to change the router ID after
you restore nonvolatile data to make the router ID unique in the
network. You may need to define preferences after restoring
nonvolatile data.
■
If trunks are defined and QoS controls are defined for these trunked
ports, the nonvolatile data conversion from Release 2.0 or 2.1 to
Release 3.0.x does not properly reindex the trunk port numbers in the
QoS controls. You must redefine the controls. (29407)
■
An administrative weight of 16 for an IP policy is not properly
converted. After the conversion, change the administrative weight
back to 16. (28641)
■
Statistics for QoS, IPX, VLAN, TCMP, IP interface, and Ethernet detail
for peak bytes and frame rates are not reset when you set a baseline
using the
module baseline set
command. (06374)
SNMP
■
For the MIB object ipDefaultTTL object, write access is allowed but the
3Com implementation does not allow values other than the default
value to be set.
■
MIB Object a3ComSysEthernetPortCount gives the value of the
combined number of front, backplane, and management ports.
(29430)
■
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.
