Release Notes for the Catalyst 1900 and Catalyst 2820 Series Switches, Version 9.00.06
OL-2901-01
Caveats
–
Enable port security on the switch port connected to the server, set the upper limit of the number
of addresses the secure port can have, and set the Action Upon Address Violation option to
Ignore.
–
Do not use the network port.
• CSCdj34652
You cannot use IP to manage the switch if the management VLAN is pruned.
The workaround is to be sure that the management VLAN is not pruned if VTP pruning is enabled.
• CSCdj92968
When the Fast EtherChannel feature is enabled, the spanning-tree state for the port channel is shown
as N/A on the Port Configuration menu for port A or port B. (The VTP pruning statistics on the VTP
Statistics Report apply to the port channel as a whole, not specifically to port A or port B.)
The workaround is to use the Fast EtherChannel Management page, the CLI, or the SNMP Bridge
MIB to find out the actual state of the port channel.
Resolved Caveats in Version 9.00.06
These problems were resolved in version 9.00.06:
• CSCdx79977
Catalyst 1900 and Catalyst 2820 switches now continue to communicate with devices that are
moved from one port to another port on the switch.
• CSCdw41694
A Catalyst 1900 switch running software version 9.00.06 no longer has severe performance
degradation caused by ports without links forwarding broadcast traffic.
• CSCdw72924
A Catalyst 1900 switch running software version 9.00.06 no longer causes address flap on uplink
ports.
• CSCdx10972
A Catalyst 1900 switch now correctly acquires a Dynamic Host Configuration Protocol (DHCP)
assigned IP address after a reset.
• CSCdx06779
When using the Cisco Secure User Registration Tool, you can now use ports one through nine on an
access-layer Catalyst 1900 or Catalyst 2820 switch. The login user is assigned to a login VLAN and

gateway now continue to exchange Cluster Membership Protocol (CMP) messages with the cluster
commander.
