3Com Router 5000 and Router 6000 Family Release Notes v2.41 • Page 10
• To get ftp mputs to work properly from a client, ftp update normal must be set on the
router.
3.2 SNMP • The router does not respond to SNMP when the user is logged into the System View. This
causes Network Management Systems such as 3Com Router Manager and 3Com Network
Director to generate errors. To resolve this, exit the System View.
• The Frame Relay MIB does not use the latest version of the RFC 2115. As a result, public MIB
variables for troubleshooting Frame Relay performance problems are not supported; (e.g.
frCircuitLogicalIfIndex) from the current FRAME_RELAY-DTE-MIB (RFC 2115)
• The router will send an initial invalid trap packet upon link down/up event, followed by the
correct Trap packet. Ignore the first trap packet, the second packet is correct.
3.3 System Management • On RPU2s when booting from the compact flash, it is possible to get the following error on
boot up: “Error encountered during checking disk, format the disk!” and the boot will not
complete. Power down the router and power it back up to clear the problem.
• Analog Modem debugging shows internal activity when no cable is connected. This indicates
that the modem is active and ready to receive or make calls.
• When saving a configuration to a non-existing directory the following message displays:
“Cannot open the configuration file, this may be caused by insufficient memory space”. This
is an incorrect message and is displayed when the user is trying to save a file to a non-
existent directory. To solve the problem, create the directory first.
• When rebooting the router, the Current Configuration change detection sometimes detects
changes when there were none, and a warning message is displayed.
• There is no way to recover if both the Bootrom password and the console password are lost.
If both passwords are lost, the router must be returned to 3Com for repair (RMA).
• FTP user cannot be cleared; set the ftp time-out to 1 minute to clear an inactive session
rather than waiting the 30 minutes set by default.
• The display current-configuration command with a filter will not recognize the underscore
character(”_”) alone. Use the backslash character (”\”) in front of the underscore to get the
desired result. For example, display current-configuration | begin bgp\_peer will display the
configuration starting with the line containing “bgp_peer”
• CPU Usage history graph has the time scale backwards; the right side is the most recent
history.
• A 1-Port Channelized E3 MIM card will not operate if inserted in slot 0 on the 5642 or slot 1
on the 5232. Select a different slot for the E3.
3.4 Interface Management • When the Dialer interfaces toggles state (up or down), minor packet loss will occur for any
packet passing through the router.
• Interface statistics with a flow-interval of under 10 seconds are not accurate. Do not enter
flow- interval values under 10 seconds.
• The Virtual-Ethernet interface protocol state displays as being down when running PPPoE.
This is the normal operating state of the Virtual-Ethernet interface.
