   Table 1 Listener parameters that you can modify

   Parameter	Description
   Name	Listener name. You can enter up to 64 characters. Only letters, digits, and hyphens are allowed.
   Port	The ports or port ranges used by the listener to receive requests from clients. The port number ranges from 1 to 65535. You can enter one or more ports or port ranges separated by commas (,). Example: 1-10,11-50,51,52-200
   Client Affinity	If you select None, the listener routes requests evenly among the endpoints in the endpoint group. If you select Source IP address, the source IP address of each request is calculated using the consistent hashing algorithm to obtain a unique hash key, and all the endpoints are numbered and mapped to the hash keys. Requests from the same IP address are forwarded to the same endpoint for processing. TCP and UDP listeners support only Source IP address.
   Access Control	You can add IP addresses to a whitelist or blacklist to control access to a listener. A whitelist allows specified IP addresses to access the listener, while a blacklist denies access from specified IP addresses. For details, see Access Control.
   Description	Supplementary information about the listener. You can enter up to 255 characters.
