Using Previous Releases of the Switch Firmware Using Previous Releases of the Switch Firmware The Catalyst 1900 and Catalyst 2820 switches are shipped with firmware version 9.00.05. Depending on the board version of your switch, you need the minimum firmware releases listed in Table 1. The “System Revision” field on the System Configuration menu displays the board revision of your switch. When you use the show version command from the command-line interface (CLI), the “Hardware Board Revision

Limitations Limitations These sections provide usage limitations for the switches. Limitation Specific to the Catalyst 2820 Switches After removing or inserting a module, click Reload to display a fresh switch image on the Home page. Limitations for the Catalyst 1900 and Catalyst 2820 Switches � Clicking Reload from any switch manager page displays a fresh copy of the Home page, not the currently displayed page. � The switch manager does not check parameter values that are outside the value ran

Usage Guidelines � If you connect an autonegotiating 100BASE-TX port of a Catalyst 1900 switch to a device that does not autonegotiate, there could be problems establishing a link. To work around this problem, configure the switch port to either half or full duplex to match the configuration of the other device. Usage Guidelines Specific to the Catalyst 2820 Switches This section describes usage guidelines specific to the Catalyst 2820 switches. � If your attempt to upgrade the ATM module firm

Usage Guidelines � If the switch is directly connected to a terminal or terminal emulator rather than to a modem connection, you must configure the switch to the same baud rate and character format as the terminal or emulator. If the switch is dialing out, the configured baud rate of the switch does not change. The Match Remote Baud rate option (auto baud) applies only when the switch is answering an incoming call and matches a rate less than or equal to the configured rate. When the call i

Caveats � While performing a firmware upgrade, the switch might not respond to commands for as long as 1 minute. This is normal and correct. If you interrupt the transfer by turning the switch off and on, the firmware could be corrupted. If this happens, follow the procedure in “Using the Diagnostic Console” in the “Troubleshooting” chapter of the Catalyst 1900 Series Installation and Configuration Guide or the Catalyst 2820 Series Installation and Configuration Guide.

Caveats � CSCdk66781 Networks that use IBM Type 1 cabling with ports configured as monitor ports can have problems if the cable becomes disconnected. The workaround is to configure ports for half-duplex operation because the switch does not detect a loopback if the hermaphroditic connector on the cable is disconnected. � CSCdk57978 In a full-duplex configuration with STP disabled, the switch does not detect a loop if an IBM Type 1 cable is disconnected. The workaround is to configure ports fo

Caveats � CSCdk01961 If you use VTP pruning with Fast EtherChannel, losing one connection on one high-speed link prevents pruning from working properly. This does not cause connectivity problems, but flood traffic is sent to the neighboring switch (which should drop such traffic, resulting in minimal degradation to network performance). Pruning still works in the neighboring switches. The workaround is to disconnect the remaining link and then to reconnect both links to restore proper operat

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

Caveats Resolved Caveats in Previous Versions These problems were resolved in version 9.00.05: � CSCds09069 Catalyst 1900 and 2820 switches can now communicate with other management VLANs even if the switch has no ARP entry in its ARP table for a default gateway or does not have a port assigned to a management VLAN. � CSCds60075 The MIB object IfLastChange now reports the correct time when the LinkUp/LinkDown Traps are disabled on the switch. � CSCdt65828 The FDDI DAS module no longer incor

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 Upgrad

Related Documentation � CSCdm58378 Whether in VTP transparent or server mode, the switch drops VTP packets from blocked ports and no longer receives and sends these packets to unblocked ports. � CSCdm83795 The switch can use a CiscoSecure NT TACACS server to authenticate access based on the switch IP address.
