Appendix C Recommendations for Upgrading a Catalyst 2950 Switch to a Catalyst 2960 Switch Configuration Compatibility Issues Table C-1 Catalyst 2950 and 2960 Switch Configuration Incompatibilities (continued) Feature Catalyst 2950 Switch Command and Explanation Result on the Catalyst 2960 Switch IEEE 802.1x In Cisco IOS 12.1EA, the Catalyst 2950 switch ranges for the IEEE 802.1x server-timeout, supp-timeout, and tx-period are 1 to 65535. You use these interface configuration commands to configure them: dot1x timeout server-timeout seconds dot1x timeout supp-timeout seconds dot1x timeout tx-period seconds In Cisco IOS 12.2SE, the IEEE 802.1x server-timeout and supp-timeout ranges are 30 to 65535. The tx-period range is 15 to 65535. For server-timeout, the Catalyst 2960 switch accepts 1 to 29 as a valid lower value and changes the value to 30. For supp-timeout, the Catalyst 2960 switch accepts 1 to 29 as a valid lower value and changes the value to 30. For tx-timeout, the Catalyst 2960 switch accepts 1 to 14 as a valid lower value and changes the value to 15. For all three commands, this message appears: IGMP1 snooping The Catalyst 2950 switch implements IGMP snooping based on MAC addresses. You use this global configuration command to configure static groups: ip igmp snooping vlan vlan-id static mac-address interface interface-id These Catalyst 2950 switch global configuration commands were implemented to address hardware limitations: ip igmp snooping source-only-learning [age-timer value] no ip igmp snooping mrouter learn pim v2 %Invalid input detected at '^' marker. The Catalyst 2960 switch implements IGMP snooping based on IP addresses and uses other advanced hardware. It rejects the Catalyst 2950 IGMP snooping commands, and these messages appear: Switch(config)# ip igmp snooping vlan 1 static 0002.4b28.c482 interface gigabitethernet0/1 ^ %Invalid input detected at '^' marker. Switch(config)# ip igmp snooping source-only-learning ^ %Invalid input detected at '^' marker. Switch(config)# no ip igmp snooping mrouter learn pim v2 ^ %Invalid input detected at '^' marker. Interface MAC address On the Catalyst 2950 switch, you can set the MAC address for both physical and switch virtual interfaces (SVIs) by using this interface configuration command: mac-address mac-address On the Catalyst 2960 switch, you cannot set the MAC address for physical and SVIs. The switch rejects the command, and this message appears: Switch(config-if)# mac-address 0100.0ccc.cccc ^ %Invalid input detected at '^' marker.
