ipV6Fragment
ipV6Fragment - configure an IPv6 fragment extension header
SYNOPSIS
ipV6Fragment sub-command options
DESCRIPTION
The ipV6Fragment command creates a fragment extension header to be used in an ipV6 header. This type of extension header is added to the ipV6 header using ipV6 addExtensionHeader.
Note that when using ATM ports, different types of ATM encapsulation result in different length headers, as discussed in atmHeader. The data portion of the packet normally follows the header, except in the case of the two LLC Bridged Ethernet choices, where 12 octets of MAC address and 2 octets of Ethernet type follow the header. The offsets used in this command is with respect to the beginning of the AAL5 packet and must be adjusted by hand to account for the header.
STANDARD OPTIONS
enableFlag true | false
Indicates whether there are more fragments to be received (true) or this is the last fragment (false). (default = true)
fragmentOffset
A 13-bit value which is the offset for the data contained in this packet, relative to the start of the fragmentable part of the original packet, in 8-octet units. (default = 100)
identification
A 32-bit value that uniquely identifies the original packet which is to be fragmented. (default = 0x11112222)
nextHeader
Read-only. The type of the next extension header.

COMMANDS
The ipV6Fragment command is invoked with the following sub-commands. If no sub-command is specified, returns a list of all sub-commands available.
ipV6Fragment cget option
Returns the current value of the configuration option given by option. Option may have any of the values accepted by the ipV6Fragment command.
ipV6Fragment config option value
Modify the IP address table configuration options of the port. If no option is specified, returns a list describing all of the available ipV6Fragment options (see STANDARD OPTIONS).
ipV6Fragment setDefault
Sets to IxTclHal default values for all configuration options.
