Wireless users connected to a BAS interface fail to obtain IPv6 addresses. However, wired users can properly obtain IP addresses.
The following figure shows the simplified topology.
ipv6 pool wxyh bas local
dns-server 2400:A980::789 2001:250:100D:ABCD::ABCD
radius-server group d
ipv6 address auto link-local
ipv6 nd autoconfig managed-address-flag
ipv6 nd autoconfig other-flag
user-vlan 2101 2150
access-type layer2-subscriber default-domain pre-authentication mac-auth authentication after-auth
2.Obtain tracing information. The customer feedback shows that no printing information is available. It can be confirmed that the device does not receive packets from terminals. This indicates that this problem occurs only for wireless users. Check whether the wireless devices can forward IPv6 packets
3.Check the AC configuration. It is found that the device is not enabled with the function to process the IPv6 packets sent by terminals.
security-profile name wlan-security
security wpa2 psk pass-phrase %^%#Jjj+Y#A1J'86p/#:o>z#f!>@$NU7t+UWfK2*uA~K%^%# aes
The ME60 configuration is normal. In consideration that IPv4 services are commonly used on the live network, to reduce device resource consumption, the function to process the IPv6 packets sent by terminals is disabled on AC-side interfaces by default.
Run the sta-ipv6-service enable command to enable the function to process the IPv6 packets sent by terminals on wireless devices.
