Cisco Bug: CSCvi62746 - Client cannot pass IPv6 traffic for 15 seconds after associating
Apr 28, 2018
- Cisco 5500 Series Wireless Controllers
Known Affected Releases
Symptom: A wireless client sees a 15 second delay when it associates to a network before it can pass IPv6 traffic. Conditions: This will occur for clients that rely solely on Stateless Address Auto-Configuration (SLAAC) router advertisements (RAs) to get an IPv6 address. That is, the clients do not send any DHCPv6 request packets. On networks that disable the SLAAC M and O bits, many clients will not send DHCPv6 even if they would normally.
