Ethernet; Bridging - 3Com 4007 Release Note

There is no SNMP support for the AppleTalk Interface Count MIB
(a3ComSysAtInterfaceCount). (05994)
You cannot configure more than one routing interface on a
multiprotocol VLAN using SNMP. Instead, configure the routing
interface through the Web Management software or the
Administration Console.
You cannot delete and then successfully recreate an
hlHostControlStatus entry using SNMP.
IPX Policies are not shown via SNMP. (28352)
The SNMP object a3ComSysEthernetPortRequestedPortMode allows
you to set values that are out of range for the port. Only use the
values 10 or 100 with this SNMP object. (30022)

Ethernet

The
ethernet detail
value for a 10/100 port. A 10/100 port does not support flow control.
If a bridging loop exists on a switching module or switch fabric
module, output from the
30 minutes to display. (30080)

Bridging

The STP pathcost does not reset to a lower value when you remove a
trunk. Manually reset the pathcost counter to the desired value.
Associated
routed frames are filtered using custom or port group filters.
When you connect a 10/100 Ethernet port to a 10BASE-T Ethernet
port, the system does not revise the default path cost to reflect the
10BASE-T Ethernet LAN segment. The 10BASE-T Ethernet port path
cost defaults to 100 when it should default to 10.
The following bridge commands may take a few minutes to complete
when several VLANs are configured in the system in allClosed mode:
bridge vlan mode
bridge vlan define
bridge vlan remove
bridge trunk define
To minimize this delay, configure VLANs in order of increasing VID and
remove them in order of decreasing VID.
display may erroneously report a flow control
