You must use the feature eou command and set the switchport mode to access before using the nac enable command.

You can enable EAPoUDP only on an access mode interface.

This command does not require a license.

Examples

This example shows how to enable NAC on an interface:

switch# config t

switch(config)# interface ethernet 1/1

switch(config-if)# switchport

switch(config-if)# switchport mode access

switch(config-if)# nac enable

This example shows how to disable NAC on an interface:

neq

To specify a not-equal-to group member for an IP port object group, use the neq command. To remove a not-equal-to group member from port object group, use the no form of this command.

[sequence-number] neq port-number

no {sequence-number | neq port-number}

Syntax Description

sequence-number	(Optional) Sequence number for this group member. Sequence numbers maintain the order of group members within an object group. Valid sequence numbers are from 1 to 4294967295. If you do not specify a sequence number, the device assigns a number that is 10 greater than the largest sequence number in the current object group.
port-number	Port number that this group member does not match. Valid values are from 0 to 65535.

Defaults

None

Command Modes

IP port object group configuration

Supported User Roles

network-admin
vdc-admin

Command History

Release	Modification
4.0(1)	This command was introduced.

Usage Guidelines

A not-equal-to group member matches port numbers that are not equal to the port number specified in the entry.

IP port object groups are not directional. Whether an neq command matches a source or destination port or whether it applies to inbound or outbound traffic depends upon how you use the object group in an ACL.

This command does not require a license.

Examples

This example shows how to configure an IP port object group named port-group-05 with a group member that matches traffic sent to any port except port 80:

switch# config t

switch(config)# object-group ip port port-group-05

switch(config-port-ogroup)# neq 80
