For more information, see Chapter34, вЂњConfiguring QoSвЂќ With flow control, all traffic is stopped. You can configure QoS to restrict data traffic without affecting the control traffic. The Catalyst 2960 switch rejects the command, and this message appears: Switch(config-if)# The flowcontrol send command is not supported on the Catalyst 2960 switch. The Catalyst 2960 switch accepts received pause frames but cannot send them. You use this interface configuration command to configure it: The Catalyst 2950 switch supports pause frames on Gigabit Ethernet interfaces. It changes the maximum value to 2048 (if it is more than 2048), and this message appears: %Invalid input detected at вЂ^вЂ™ marker.% The Catalyst 2960 switch accepts any range value. In Cisco IOS 12.2SE, the range was changed to 1 to 2048 messages per second. The range is 1 to 4294967294, and by default, the rate limit is not configured. The Catalyst 2960 switch rejects the command, and this message appears: Switch(config)#ДЄ Catalyst 2950 switch DHCP snooping feature limits the number of DHCP packets per second that an interface can receive. With the Catalyst 2960 switch, you can connect to candidate and cluster member switches through any VLAN in common with the cluster command switch. This command communicates the management VLAN when the switch is configured for clustering. You can use this global configuration command to change it: The Catalyst 2950 switch supports only one management VLAN. The Catalyst 2960 switch rejects these commands, and this message appears: Switch(config)# When Cisco IOS 12.2E was restructured, these commands were intentionally removed and are not supported in Cisco IOS 12.2SE. These global configuration commands are in Cisco IOS 12.1EA:

The features are listed in alphabetic order, with Catalyst 2950 commands and explanations, and the resulting action on the Catalyst 2960 switch. Table A-1 lists the Catalyst 2950 exceptions. In most cases, configuration files are loaded without rejections.

CISCO 2950 SWITCH CONFIGURATION COMMANDS SOFTWARE

The Catalyst 2960 switch software handles the incompatible commands in these ways: If you use a Catalyst 2950 switch command, it might not be supported on the Catalyst 2960 switch.

The switch families have different hardware.

The Catalyst 2950 switch runs Cisco IOS 12.1EA software, and the Catalyst 2960 switch runs Cisco IOS 12.2SE software.

The configuration commands between the two switch platforms differ for these reasons: This appendix consists of these sections:
