g. Configure TCP access to this port:
i. Set the connection type:
(config serial USB_port)> service tcp conn_type value
(config serial USB_port)>
where value is one of:
i. tcp: The TCP connection is unencrypted.
ii. tls: The TCP connection uses Transport Layer Security (TLS) encryption.
iii. tls_auth: The TCP connection uses TLS encryption with authentication.
ii. Enable TCP access:
(config serial USB_port)> service tcp enable true
(config serial USB_port)>
iii. Set the TCP port:
(config serial USB_port)> service tcp port port
(config serial USB_port)>
iv. (Optional) Configure the access control list to limit access to the TCP connection:
n To limit access to specified IPv4 addresses and networks:
(config serial USB_port)> add service tcp acl address end
value
(config serial USB_port)>
Where value can be:
l A single IP address or host name.
l A network designation in CIDR notation, for example, 192.168.1.0/24.
l any: No limit to IPv4 addresses that can access the tcp port.
Repeat this step to list additional IP addresses or networks.
n To limit access to specified IPv6 addresses and networks:
(config serial USB_port)> add service tcp acl address6 end
value
(config serial USB_port)>
Where value can be:
l A single IP address or host name.
l A network designation in CIDR notation, for example, 2001:db8::/48.
l any: No limit to IPv6 addresses that can access the tcp port.
