TCP Half Close support for TCP Proxy and SOCKS Proxy
TCP Half Close refers to a TCP connection that is half-closed. So if one participant in a TCP connection has initiated FIN in one direction, then it can still receive data from another participant until the second FIN is received from the other direction. TCP Half Close support is provided for SWG acting as TCP Proxy or SOCKS Proxy. For details, see TCP Half Close for TCP or SOCKS Proxy.

You can now configure separate passwords for Authentication and Encryption for the SNMPv3 messages. For details, see Configure Event Monitoring with SNMP.
