Parameters
vpn-instance
vpn-instance-name
: Specifies an MPLS L3VPN instance by its name, a
case-sensitive string of 1 to 31 characters. If the log host is on the public network, do not specify this
option.
hostname
: Specifies a log host by its name, a case-insensitive string of 1 to 253 characters. The host
name can contain letters, digits, and special characters including hyphen (-), underscore (_), and dot
(.).
ipv4-address
: Specifies a log host by its IPv4 address. The address must be a valid unicast address
and cannot be a loopback address.
ipv6
ipv6-address
: Specifies a log host by its IPv6 address.
port udp-port
: Specifies the UDP port number of the log host, in the range of 1 to 65535. As a best
practice, use UDP port numbers in the range 1025 to 65535 to avoid collision with well-known UDP
port numbers.
