This command configures the method used to set the high 6 bits (the differentiated services codepoint)
of the IPv4 TOS or the IPv6 traffic class in the outer IP header.
A value of 0 copies original packet DSCP (IPv4)/Traffic Class (IPv6) to the tunnel header DSCP (IPv4)/
Traffic Class (IPv6) depending on the mode of tunnel.
tunnel destination

Syntax
tunnel destination {ip-address | ipv6–address}
To delete a tunnel destination address, use the no tunnel destination {ip-address | ipv6–

9.3(0.0) Introduced on the MXL 10/40GbE Switch IO Module.
Usage
Information
The tunnel interface is inoperable without a valid tunnel destination address for the configured Tunnel
mode.
To establish a logical tunnel to the particular destination address, use the destination address of the
outer tunnel header. If you configure a tunnel interface or source address, the tunnel destination must be
compatible.
tunnel flow-label
