■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 mode command. Type:
Console#configure
Console(config)#spanning-tree
Console(config)#spanning-tree mode rstp
To change the initial spanning tree mode from the default (RSTP) to STP with spanning tree disabled, type:
Console#configure
Console(config)#spanning-tree
Console(config)#spanning-tree mode rstp
Console(config)#no spanning-tree
■4790634: The SSC-to-switch communication protocol might not supply the switch’s DHCP client identifier in time for the switch to make a DHCP request On a reset of the switch after the SSC unit has been moved into a different slot or into a new chassis (or after the DHCP client identifier has 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.
