Hi Martin, I just did some testing on a Cisco 3550-PWR 24 port switch using port security. I started with IOS 12.2(35)SE5 and ran into some issues. After upgrading to 12.2(44)SE6 it worked.
Also if you are doing Cisco VoIP, you have to change your port configuration on the 3550 and 3560 switches from using the older Trunk VoIP port config used on the 3524 switches to the Access port with Voice Vlan config. There is one note in the Cisco Switch Configuration Guide for IOS 12.2(55)SE page 23-12 for setting up Port-Security that says "Voice VLAN is only supported on access ports and not trunk ports, even though the configuration is allowed". This gave me a lot of trouble testing port security on the 3550 and 3560 when they were configured as Trunk ports. This is a sample config for a 3550 and 3560 switch port using port security with VoIP. interface FastEthernet0/1 description F0/1 PF access-voice switchport access vlan 81 switchport mode access switchport voice vlan 181 switchport port-security maximum 2 switchport port-security maximum 1 vlan access switchport port-security maximum 1 vlan voice switchport port-security switchport port-security violation restrict switchport port-security mac-address 0200.0000.0001 priority-queue out spanning-tree portfast This is a sample config for an older 3524 switch port using Mac Detection with VoIP. The 3524 would not work with the Access port and Voice VLAN config above. interface FastEthernet0/1 description F0/1 PF MAC DOT1Q port to IP Phone switchport trunk encapsulation dot1q switchport trunk native vlan 4 switchport mode trunk switchport voice vlan 181 switchport priority extend cos 0 snmp trap mac-notification added snmp trap mac-notification removed spanning-tree portfast Thank You, Kerry Melcher -----Original Message----- From: Martin Soentgenrath [mailto:[email protected]] Sent: Wednesday, January 05, 2011 4:52 AM To: [email protected] Subject: [Packetfence-users] IOS Version Cisco 3550 Hi there, which is the preferred supported IOS Version for the Cisco Catalyst 3550 Switch? I would like to test this Switch with Port Security Traps, and was not able to find Information regarding the IOS Version on http://www.packetfence.org/documentation/pod/SNMP/Cisco/Catalyst_3550.html.
