NEAT changes the port configuration on the authenticator switch. So, to perform ISSU from one v ersion
that supports NEAT to another that does not support NEAT, you must first deactivate NEAT on all switch
ports for ISSU. Similarly, NEAT cannot activate when ISSU is in progress. If a supplicant switch tries
to authenticate during ISSU, authorization would fail on the port.
Configuring Switch as a Supplicant
Note The Catalyst 4500 series switch does not support supplicant switch functionality. The following
supplicant specific commands are mentioned for a quick reference. For more details, see the
Catalyst 3750 Switch Software Configuration Guide.
To configure a switch as a supplicant, perform this task:
Command Purpose
Step 1 Switch# configure terminal Enters global configuration mode.
Step 2 Switch(config)# cisp enable Enables CISP.
Step 3 Switch(config)# dot1x credentials
profile Creates 802.1x credentials profile. This must be attached to the port that
is configured as supplicant.
Step 4 Switch(config)# sername suppswitch Creates a username.
Step 5 Switch(config)# password password Creates a password for the new username.
Step 6 Switch(config)# dot1x supplicant
force-multicast Forces the switch to send only multicast EAPOL packets when it
receives either unicast or multicast packets.
This also allows NEAT to work on the supplicant switch in all host
modes.
Step 7 Switch(config)# interface
interface-id Specifies the port to be configured, and enter interface configuration
mode.
Step 8 Switch(config-if)# switchport
trunk encapsulation dot1q Sets the port to trunk mode.
Step 9 Switch(config-if)# switchport mode
trunk Configures the interface as a VLAN trunk port.
Step 10 Switch(config-if)# dot1x pae
supplicant Configures the interface as a port access entity (PAE) supplicant.
Step 11 Switch(config-if)# dot1x
credentials profile-name Attaches the 802.1x credentials profile to the interface.
Step 12 Switch(config-if)# end Returns to privileged EXEC mode.
