Configure an I-SID offset value, and globally enable I-SID offset for the Extensible Authentication Protocol (EAPoL) feature. The I-SID offset value is used to calculate an I-SID value for a Switched UNI if no I-SID value is provided by the RADIUS server. In that case, the I-SID value is calculated as follows: I-SID = VLAN ID + configured I-SID offset value.
default eapol auto-isid-offset
eapol auto-isid-offset <0-15995903>
eapol auto-isid-offset enable
no eapol auto-isid-offset enable
The default status is disabled, and the default I-SID offset value is 15990000.
Global Configuration
Configure the I-SID offset value first, and then enable I-SID offset globally on the switch.
