after configuring snmp and telnet template parameters on both FW and esight
login to FW via web browser
under Network > Interfaces
navigate to the interface that will receive SNMP from eSight
under Access Management
This function allows an administrator to access a FW using HTTP, HTTPS, ping, SSH, SNMP, NETCONF, or Telnet. Interface access control takes precedence over security policies. This means that an administrator can use an access control-enabled interface to access a FW even if no security policy is configured for communication between the zone of the interface and a local zone.
By default, the management interface (GigabitEthernet 0/0/0) allows HTTP, HTTPS, ping. access to a FW, and a non-management interface denies HTTP, HTTPS, ping, SSH, SNMP, NETCONF, or Telnet. access to a FW.

same apply to telnet access from esight to FW
Telnet: allows an administrator to use Telnet to access a device. If Telnet is not selected, the interface discards them after receiving them.
