17. If Hewlett-Packard GBIC (Gigabit Ethernet Interface Converter) modules are inserted/removed on the
ELS100-24TXG while power is applied to the switch, they may become damaged. The damage results
in the presence and type identity of the GBIC not being recognized by software. Data will still be
switched successfully through the port.
18. The following issues are present when using the Port Trunking feature in this release of firmware:
−
When configuring Port Trunking, the Spanning Tree path costs on ports can become
misconfigured.
−
Ports in different VLANs can be placed into the same trunk, which should not be allowed.
−
Trying to add a port to a trunk that has been created in a different switch cluster (group of 8 ports)
causes the ports in the trunk to be erroneously deleted.
−
When a trunk group is configured, and the first port of that trunk group becomes disabled, local
management reports that the entire trunk status is disabled; this is a false signal. The status can
be corrected by disabling and re-enabling that port.
−
This release does not provide compatibility with DEC Hunt Group proprietary protocol mode of
operation; this functionality will be provided in a future release.
Please refer to the addendum to the ELS100-24TXG/TXM User Guides (Document # 9033194) for
detailed information regarding port trunking configuration.
19. When a BootP server and DHCP server are both present in the network, in some cases only the IP
address will be acquired; the firmware image will not be received. Both protocols work properly when
only one server type is present. This condition also existed in earlier versions of firmware. Cabletron’s
recommendation is to remove the DHCP server and reboot the switch; this will cause the switch to send
BootP requests and receive an image from the BootP server.
20. When Microsoft Internet Explorer is used to access Cabletron WebView management, the initial start-
up time is excessive (approximately 20 minutes), after which it performs normally. To avoid this delay,
the switch’s IP address should be added to Internet Explorer’s Proxies “Ignore” area.
21. When using Cabletron WebView, an ELS100-24TXM which does not have an uplink installed is
incorrectly reported to be an ELS100-24TX. This condition also existed in earlier versions of firmware.
22. Older versions of ELS100-24TX may not support the Cabletron WebView image download, due to
insufficient memory.
23. When configuring 802.1Q trunks, the VLAN that contains the ports configured as trunks must not have
those ports on the egress list for that VLAN. This results in a mis-configuration.
24. When configuring Port Trunks as 802.1Q trunks, you must add the port trunks to the egress list as a
pair. Adding them separately results in an error reporting a VLAN violation.
25. When performing a TFTP file download to the switch, it may be necessary to repeat the process to
successfully receive the entire file. Also, if a file that has been received is corrupt, the switch may enter
a state where it is expecting to receive a new image via XMODEM download. This can be verified and
corrected by invoking a local management session to the console (serial) port; the switch will send the
character “c” to the console station until an XMODEM transfer of a new firmware image file is sent. For
additional information, please reference http://www.cabletron.com/support/techtips/tk0564-9.html
for XMODEM instructions, and http://www.cabletron.com/support/techtips/tk0490-9.html
for
TFTP/BootP instructions.
26. Contrary to the user manuals, the READ/WRITE and READ-ONLY passwords are case-sensitive in this
version of firmware. The passwords must be typed exactly as they were created.
27. (Added 2/7/2000): The READ ONLY password is not saved to non-volatile memory. It will become
effective and active when created, but will not be saved when the device is reset. Resetting the device
clears the READ ONLY password. Also, when the READ/WRITE password is modified and saved, this
will clear the READ ONLY password, allowing READ access with just a carriage return at the Login:
prompt. These problems will be resolved in the next firmware release.
Any other problems than those listed above should be reported to our Technical Support Staff.
