Description:
Bug ID 1391525: Timestamp Cookies and ePVA acceleration are incompatible on VELOS and rSeries platforms ... Last Modified: May 14, 2024 ... Symptoms ... VELOS and rSeries platforms don't support Timestamp Cookies when ePVA acceleration is enabled. ... When Timestamps Cookies and ePVA acceleration are enabled, the BIG-IP Tenant sends TCP segments to the clients with the wrong TSecr value (part of the TCP Timestamps option). ... Some clients drop these segments because they don't match any of the Timpestamps TSval values of the segments they previously sent to the BIG-IP Tenant. ... Impact ... The BIG-IP Tenant sends TCP segments with a wrong TCP TSecr value to the clients when Timestamp Cookies are enabled and ePVA acceleration is used. ... Some clients drop these packets and eventually the TCP connection times out. ... Some clients may issue a TCP reset. ... Conditions
