Table 212 ipv6 icmp and ping6 Commands
COMMAND DESCRIPTION M P
ping6 < ipv6-address > <[-i
< interface-type > < interface-
number >] [-t] [-l <1-1452>] [-n <1-
65535>] [-s < ipv6-address >]
Sends IPv6 ping packets to the specified
Ethernet device.
interface-type
: the OLT supports only the
VLAN interface type at the time of writing.
interface-number
: The VLAN ID to which the
Ethernet device belongs.
-l <1-1452>
: Specifies the size of the ping
packet.
-t
: Sends ping packets to the Ethernet device
indefinitely. Press
[CTRL]+C
to terminate the
Ping process.
-n <1-65535>
: Specifies how many times the
OLT sends the ping packets.
-s < ipv6-address >
: Specifies the source IPv6
address of the pin packets.
E 0
show ipv6 mtu
Displays IPv6 path MTU information on the OLT.
The OLT uses Path MTU Discovery to discover
Path MTU (PMTU), that is, the minimum link MTU
of all the links in a path to the destination. If the
OLT receives an ICMPv6 Packet Too Big error
message after sending a packet, it adjusts the
next packet size according to the suggested
MTU in the error message.
E 3
Table 213 ipv6 nd Commands
COMMAND DESCRIPTION M P
vlan <1-4094>
Enters config-route-domain mode for the
specified VLAN. Creates the VLAN, if necessary. C 13
ipv6 nd dad-attempts <0-600>
Sets the number of consecutive neighbor
solicitations the OLT sends for this VLAN.
The OLT uses Duplicate Address Detection (DAD)
with neighbor solicitation and advertisement
messages to check whether an IPv6 address is
already in use before assigning it to an interface,
such as the link-local address it creates through
stateless address autoconfiguration for this
VLAN.
To turn off the DAD for this VLAN, set the number
of DAD attempts to 0.
C 13
ipv6 nd managed-config-flag
Configures the OLT to set the “managed
address configuration” flag (the M flag) to 1 in
IPv6 router advertisements, which means hosts
use DHCPv6 to obtain IPv6 stateful addresses. C 13
ipv6 nd ns-interval <1000-
3600000>
Specifies the time interval (in milliseconds) at
which neighbor solicitations are re-sent for this
VLAN. C 13
