Hi, All! I have Cisco Catalyst 3550. Recently, I have upgraded Cisco IOS. After upgrading IOS, ACL isn't working any more. WHY??? Maybe not enought TCAM resources?.. but in the previous IOS ACEs were functioning properly.
On the switch I have QoS, DHCP Snooping, Dinamic ARP Inspector, VLANs, SNMP running.
Old Cisco IOS: 12.2 (25) SEE IPSERVICES
new IOS: 12.2 (44) SE
Help me, please! Maybe somebody had similar problem?
