ISE 3.2 Patch 3 or ISE 3.3
Interface associated with portals with only ipv6 enable command configured.
interface GigabitEthernet 0
ip address 14.36.144.23 255.255.0.0
ipv6 enable
Workaround
Two workarounds have been identified. Either disable ipv6 on the interface or configure it with an ipv6 address command.
Workaround 1 - Disable IPV6 on the interface:
configure terminal
interface GigabitEthernet 0
no ipv6 enable
Workaround 2 - Configure an ipv6 address command:
configure terminal
interface GigabitEthernet 0
ipv6 address autoconfig
or
configure terminal
interface GigabitEthernet 0
ipv6 address dhcp
or
configure terminal
interface GigabitEthernet 0
ipv6 address [valid IPv6 format(/0-128)]
