■4773408: Spanning tree mode cannot be set when spanning tree support is
disabled
Setting the spanning tree mode for the switch can only be done when spanning
tree is enabled. If you wish to set the initial spanning tree mode for the switch to
a particular setting (for example in a configuration file) you must ensure that
spanning tree is enabled before issuing the spanning-tree modecommand.
Type:
Tochange the initial spanning tree mode from the default (RSTP) to STP with
spanning tree disabled, type:
■4790634: The SSC-to-switch communication protocol might not supply the
switch’s DHCP client identifier in time for the switch to make aDHCP request
On a reset of the switch after the SSC unit has been moved into a differentslot or
into a new chassis (or after the DHCP client identifierhas been changed manually
from the switch’s command-line interface), it is theoretically possible that the
switch will make two DHCP requests. This has not been observed in testing.
There is currently no workaround for this issue; however,there are no serious
consequences of it either.
