2. Known Issues for 3Com MSR

2.1

System Management

•
The "Remove Slot" command does not remove the module from the H/W inventory list.
•
The rlogin command is not supported.
•
FTP clients cannot list a directory when the FTP server is not listening on port 21. 3Com
recommends that you always configure to port 21.
2.2

Interface Management

•
If incoming packets are dropped due to the CPU overloading, the dropped packets are
not counted or recorded.
•
If load-sharing is configured, packets are counted but the number of flows is not.
•
Some CLI commands are only available for certain interfaces, (for example, router or
bridge interfaces). If one of these commands is entered from the CLI, but an
appropriate interface is not installed, the error message 'unrecognized command' will
be displayed.
•
4-Port FSW and 9-Port FSW modules support port mirroring in inbound direction only.
2.3

Link Layer Protocol

•
Link auto-negotiation does not succeed between PC and 4FSW / 9FSW SICs if the PC
uses the Intel i82555 chipset. Use fixed speed/duplex option in this case.
