Release Notes for the Catalyst 1900 and Catalyst 2820 Series Switches, Version 9.00.06
OL-2901-01
Caveats
This problem was resolved in version 9.00.04:
• CSCds28410
Version 9.00.04 corrected a condition on the Catalyst 1900 and 2820 switches running Enterprise
Edition firmware that caused VLAN Trunk Protocol (VTP) configuration information to be lost. The
VTP mode changes from transparent or server mode to client mode after VTP parameters are
configured. In version 9.00.03, these parameters were lost after the switch was reset, and the switch
would revert back to server mode.
Note Upgrading to version 9.00.04 can cause the loss of restricted static addresses. If you have a
restricted static addresses configured, save your configuration file to a TFTP server before
upgrading. Upgrade to version 9.00.04, and then reload your configuration file.
This problem was resolved in version 9.00.03:
• CSCdr50274
Version 9.00.03 corrected an anomolous user-invoked system reset condition. If you reset the system
through the console interface (as opposed to recycling power), it was statistically possible for a
single, random port on the unit to fail to acquire link and operate properly. You would then observe
a nonfunctional or dead port. Power cycling the switch corrected the problem. The software
modification reset all ports in the switch so that a port cannot lock up immediately after a
user-invoked reset.
This problem was resolved in version 9.00.02:
• CSCdp70664
Catalyst 1900 and 2820 switches no longer cause spanning-tree loops when UplinkFast is enabled.
These problems were resolved in version 9.00.01:
• CSCdp09675
If you issue a Get_Next_Request in an SNMP MIB list on an interface, there is no longer an extra
entry at the end that does not belong.
• CSCdm14589
In a Telnet session, the paste function in the CLI configuration mode now works correctly.
These problems were resolved in version 9.00.00:
• CSCdp22047
The CDP checksum algorithm is now compatible with the Cisco IOS software. Previously, when a
CDP packet had an odd number of bytes and the value of the last byte was greater than 0x80, the
device sending the packet was not recognized as a neighbor.
• CSCdm80245
You can use a DEC Alpha 1000a BOOTP server to automatically assign an IP address to the switch.
• CSCdm85421
The switch can now autoconfigure from a DHCP server that is not Windows NT.
• CSCdm87247
You can use the ipNetToMediaEntry MIB object from a Catalyst 1900 WS-C1912 model.
