interfaces tunnel <tunx> parameters ipv6 tclass <class>
Sets the value to write into the tclass byte of the IPv6 header of a tunnel packet.
The default value is inherit.
- tunx
- The identifier of a tunnel interface. The identifier ranges from tun0 through tunx, where x is a nonnegative integer.
- 0-0xff
- The value to write into the tclass byte in the IPv6 header of a tunnel packet (the carrier packet). The value ranges from 0 through 0xff, where 0 means a tunnel packet copies the tclass byte from the packet being encapsulated (the passenger packet).
- inherit
- The default traffic class of the encapsulating IPv6 header.
Configuration mode
interfaces {
tunnel tunx {
parameters {
ipv6 {
tclass 0-0xff
}
}
}
}
The tclass byte of the encapsulated packet is copied into the tclass byte of the IPv6 header of a tunnel packet. The tclass byte of the IPv6 header of a packet specifies the forwarding behavior to be applied to the packet.
Use the set form of this command to set the value to write into the tclass byte of the IPv6 header for a packet that traverses a tunnel interface.
Use the delete form of this command to restore the default behavior for the tclass field, that is, the tclass byte of the encapsulated packet is copied into the tclass byte of the IPv6 header of the tunnel packet.
Use the show form of this command to display the current tclass value to write into the IPv6 header of a tunnel packet.
