Is persistence required to be enabled on the F5 load balancer -
说明
Is persistence required to be enabled on the F5 load balancer when being used for TPAM? During multiple DR tests using an F5 seeing disconnects and the networking team confirmed that persistence is not enabled. -
原因
Having persistence disable will cause disconnects. -
解决办法
Persistence should be enabled.
Cookie persistence
Cookie persistence uses an HTTP cookie stored on a clients computer to
allow the client to reconnect to the same server previously visited at a
web site.
Destination address affinity persistence
Also known as sticky persistence, destination address affinity persistence
supports TCP and UDP protocols, and directs session requests to the same
server based solely on the destination IP address of a packet.
Hash persistence
Hash persistence allows you to create a persistence hash based on an
existing iRule.
SIP persistence
SIP persistence is a type of persistence used for servers that receive
Session Initiation Protocol (SIP) messages sent through UDP, SCTP, or TCP.
Source address affinity persistence
Also known as simple persistence, source address affinity persistence
supports TCP and UDP protocols, and directs session requests to the same
server based solely on the source IP address of a packet.
SSL persistence
SSL persistence is a type of persistence that tracks non-terminated SSL
sessions, using the SSL session ID. To enable persistence for terminated
SSL sessions, see Chapter 9, Managing SSL Traffic, Chapter 17, Writing
iRules, and the F5 Networks DevCentral web site, http://devcentral.f5.com.
Universal persistence
Universal persistence allows you to write an expression that defines what
to persist on in a packet. The expression, written using the same
expression syntax that you use in iRulesTM, defines some sequence of bytes
to use as a session identifier.
