Port Status - Field HelpEdit any of the following configuration settings on the Content Based Routing Port Status panel and click Update Configuration. Default sticky timeThe sticky time for this port. Sticky time is used to create an affinity relationship between a client and a specific server. After the sticky time has been exceeded, the client may be sent to a server different from the previous. The default value is 0, meaning that the port is not sticky. Sticky time can also be set at the executor and cluster levels. Stale timeoutThe number of seconds during which there can be no activity on a connection before that connection is removed. For CBR with WTE, the default value for port 21 is 900; the default value for port 23 is 32,000,000. The default value for all other ports is 300 and can also be set at the executor and cluster levels. For CBR proxy, the default stale timeout value for ports is 60. The default stale timeout value can also be set at the executor and cluster levels. Weight boundThe weight bound for this port. The default value is 20 and can also be set at the executor and cluster level. Maximum number of serversThe maximum number of servers for this port. The default value is 32 and can also be set at the executor and cluster levels. Server(s) listening on portIf the port on the server is different from the incoming port from the client, then set this value to the port number on the server. For instance, if the client port uses SSL (port 443) and the server port users HTTP (port 80), then you would set the "server (s) listening on port" value to 80. The default is the client's (incoming) port number. Note: This option is only available for CBR with WTE (Caching Proxy). The following current statistics are also displayed on the Port Status panel: Cluster addressThe IP address of the cluster to which port is defined. Port numberThe number of the port. ProtocolThe type of protocol being used, either POP3 or IMAP. Note:Valid for CBR proxy only Maximum server weightThe maximum server weight for servers on this port. The weight is based on internal counters in the executor, feedback from the advisors, and feedback from a system-monitoring program such as ISS. Total active connectionsThe current total number of active connections for this port. List of ServersThe numerical dotted decimal address (such as 9.37.52.11) and weight (such as 10) of the currently active servers. Weights are applied to all servers on a port. Requests will be distributed between servers based on their weights relative to each other. For example, if one server is set to a weight of 10 and the other to 5, the server set to 10 should get twice as many requests as the server set to 5.
