46 Chapter 1 About Ethernet Switches 325 and 425320985-A Rev 01SNMP trap port enhancementThe SNMP trap port enhancement allows you to configure the SNMP trap port.The default SNMP trap port used for communicating with the trap receiver is port162. You can now configure a different SNMP trap port using the following CLIcommand:snmp-server host [port <1-65535>]{|v2c |v3 {auth|no-auth|auth-priv} }For more information, see Configuring and Managing Security for NortelEthernet Switches 325 and 425, Software Release 3.6 (320988-A).EAPoL with Guest VLANPrior to Release 3.6, EAP (802.1x) Authentication supported Port Based UserAccess. At any time, only one user (MAC) could be authenticated on a port, andthe port could be assigned to only one Port-based VLAN. Only the MAC addressof the device/user that completed the EAP negotiations on the port had access tothat port for traffic. Any tagging of ingress packets would be to the PVID of thatport. This remains the default configuration.With Software Release 3.6, EAP also allows Guest VLANs to be configured foraccess to that port. Any active VLAN can be made a Guest VLAN.For more information, see Configuring and Managing Security for NortelEthernet Switches 325 and 425, Software Release 3.6 (320988-A).shutdown commandThe shutdown CLI command allows you to safely shut down and power off theswitch. Once the shutdown command is initiated, the switch saves the currentconfiguration, allowing you to power off the switch within the specified timeperiod (1 to 60 minutes). If the switch is not powered off within the allotted time,the switch performs a reset.
