Syslog Over IPv6
To support both IPv4 and IPv6, management of IPv6 networks requires both IPv6 and IPv4 transports.
Syslog over IPv6 is responsible for transporting Cisco IOS-generated system error messages to
configured servers. Syslog configures the connection to the logging host by using a Cisco IOS socket
interface and starts a socket connection on the UDP or TCP transport by using Cisco IOS sockets.
Syslog supports common address data types that support both IPv4 and IPv6 transports. The syslog
supports socket structures and APIs based on the user's CLI configurations. Socket structures and APIs
support both IPv4 and IPv6 sockets.
The user specifies an IPv4-based logging host (syslog server) by using a host IP address in IPv4 format
(i.e. 198.133.219.25). The user also specifies the TCP or UDP transport by using the IPv6 address (for
example, ABCD:088A:EF75:1774::FFFF) of a logging host (syslog server) that supports IPv6 transport.
For syslog, IPv4 requires a 32-bit. IPv6 requires a 128-bit address.
