Hi,
Im trying to configure Packetfence to deny access to all devices, unless they
are registered. I pretend to use packetfence and through snmp communicate with
a cisco switch and control port-security, so if mac is allowed the right vlan
is given and mac associated to the port...
PacketFence Info:
Version: 13.0.0
Cisco Switch:
Model: ME-C3750-24TE-M
Version: IOS 12.2
PacketFence Configuration:
Roles:
* Role "Custom Created"
Nodes:
* Mannually Created, mac address added and Role "Custom" attributed.
* MAC: 30:85:A9:05:80:B4
Switches:
* Added the test switch x.x.x.220
* Dynamic Uplinks enabled
* Roles
* VLAN ID (enabled)
* registration: 1000
* isolation: 1001
* macDetection: 1006
* Custom: 99
* Default: 99
* SNMP
* Version: v2c
* Community Read: X
* Community Write: Y
* Engine ID: 8000000903000021A1B34383
* Version Trap: v2c
* Community Trap: Y
Switch Configuration:

On PacketFence I receive the following log on
"/usr/local/pf/logs/snmptrapd.log":

Could someone help me understading if there is any error with snmp or wrong
config for packetfence out of band vlan enforcing using only SNMP?
