Wireless Users Accessed from an ME60 Fail to Obtain IPv6 Addresses

Publication Date:  2019-03-27 Views:  70 Downloads:  0

Issue Description

  1. Wireless users connected to a BAS interface fail to obtain IPv6 addresses. However, wired users can properly obtain IP addresses.

  2. The following figure shows the simplified topology.

Handling Process

1.Check that the device configuration is normal.

ipv6 prefix wxyh local
 prefix 2001:250:3C0F:2000::/64
ipv6 pool wxyh bas local
 dns-server 2400:A980::789 2001:250:100D:ABCD::ABCD
 prefix wxyh

domain mac-auth
 authentication-scheme e
 accounting-scheme acct2
 ip-pool wxyh
 ipv6-pool wxyh
 mac-authentication enable
 radius-server group d

interface Eth-Trunk2.1
 description TO_YX-HX-S12708-bas
 ipv6 enable
 ipv6 address auto link-local
 ipv6 nd autoconfig managed-address-flag
 ipv6 nd autoconfig other-flag
 user-vlan 2101 2150
 bas
 #
  access-type layer2-subscriber default-domain pre-authentication mac-auth authentication after-auth
  authentication-method web
  authentication-method-ipv6 web
  wlan-switch enable
  ip-trigger
  arp-trigger
  ipv6-trigger
  nd-trigger

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.

wlan
 security-profile name wlan-security
  security wpa2 psk pass-phrase %^%#Jjj+Y#A1J'86p/#:o>z#f!>@$NU7t+UWfK2*uA~K%^%# aes

Root Cause

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.

Solution

Run the sta-ipv6-service enable command to enable the function to process the IPv6 packets sent by terminals on wireless devices.
