Concept Guide

This command will fail if the address family entered does not match the outer header address family of the tunnel
mode, tunnel source, or any other tunnel allow-remote.
If any allow-remote are congured, the tunnel source or tunnel mode commands will fail if the outer header address
family does not match that of the congured allow-remote.
tunnel dscp
Congure the method to set the DSCP in the outer tunnel header.
Syntax
tunnel dscp {mapped | <value>}
To use the default tunnel mapping behavior, use the no tunnel dscp value command.
Parameters
mapped Enter the keyword mapped to map the original packet DSCP (IPv4)/Trac Class (IPv6)
to the tunnel header DSCP (IPv4)/Trac Class (IPv6) depending on the mode of tunnel.
value Enter a value to set the DSCP value in the tunnel header. The range is from 0 to 63. The
default value of 0 denotes mapping of original packet DSCP (IPv4)/Trac Class (IPv6) to
the tunnel header DSCP (IPv4)/Trac Class (IPv6) depending on the mode of tunnel.
Defaults 0 (Mapped)
Command Modes INTERFACE TUNNEL (conf-if-tu)
Supported Modes Full–Switch
Command History
Version Description
9.9(0.0) Introduced on the FN IOM.
9.3(0.0) Introduced on the MXL 10/40GbE Switch IO Module.
Usage Information
This command congures the method used to set the high 6 bits (the dierentiated services codepoint) of the
IPv4 TOS or the IPv6 trac class in the outer IP header.
A value of 0 copies original packet DSCP (IPv4)/Trac Class (IPv6) to the tunnel header DSCP (IPv4)/Trac
Class (IPv6) depending on the mode of tunnel.
tunnel destination
Set a destination endpoint for the tunnel.
Syntax
tunnel destination {ip-address | ipv6–address}
To delete a tunnel destination address, use the no tunnel destination {ip-address | ipv6–
address} command.
Parameters
ip-address Enter the destination IPv4 address for the tunnel.
ipv6–address Enter the destination IPv6 address for the tunnel.
Defaults none
