ALTER SUBNET Command for TCP6MAN
IPv6 configuration associated with the interface, including all IPv6 addresses and
IPv6 routes through the interface.
IPV6NUD ON | OFF
enables (ON) or disables (OFF) Neighbor Unreachability Detection.
IPV6MTU val
alters the maximum transfer unit (MTU) for messages that the system transmits on
the link. The minimum value is 1280 bytes. The maximum value is 65535 bytes.
The actual maximum value is determined from the interface with SLSA as the PIF's
Max_Frame_Size - 14. The value 14 is subtracted because MTU does not include
the Ethernet header overhead of 14 bytes.
IPV6REACHABLETIME val
specifies the number of milliseconds a cache entry is reachable without
confirmation. The default is 30000 milliseconds.
IPV6RETRANSMITIMER val
specifies the number of milliseconds between neighbor solicitation messages. The
default is 1000 milliseconds.
IPV6DADRETRIES val
specifies number of times the protocol performs duplicate address detection.
IPV6HOPLIMIT val
specifies the unicast current hop limit. The default is 64.
IPV6RAENABLE { ON | OFF }
enables (ON) the TCP6MON process to perform these tasks when a router
advertisement (RA) is received:
•
Router Discovery. The TCP6MON process learns the IPv6 address of a router
and installs default routes in the NonStop TCP/IPv6 routing tables.
•
On-Link Prefix Discovery. The TCP6MON process learns IPv6 on-link prefix
(ranges of IPv6 addresses that are directly reachable on a given link).
•
Stateless Address Configuration. The TCP6MON process automatically
creates and deletes interface addresses.
•
Interface Attribute Configuration. The TCP6MON process automatically
configures datalink attributes such as hop limit, reachable time, retransmit time,
and link MTU.
