Usage guidelines This command is effective only when the IPsec encapsulation mode is tunnel mode. It is not effective in transport mode because outer IP headers are not added in transport mode. This command does not change the DF bit for the original IP headers of encapsulated packets. If multiple interfaces have referenced an IPsec policy that is bound to a source interface, you must use the same DF bit setting on these interfaces. Examples # Set the DF bit for outer IP headers of encapsulated IPsec packets on VLAN-interface 1. system-view [Sysname] interface vlan-interface1 [Sysname-Vlan-interface1] ipsec df-bit set Related commands ipsec global-df-bit ipsec global-df-bit Use ipsec global-df-bit to set the DF bit for IP headers of encapsulated IPsec packets on all interfaces.

Usage guidelines

This command is effective only when the IPsec encapsulation mode is tunnel mode. It is not effective in

transport mode because outer IP headers are not added in transport mode.

This command does not change the DF bit for the original IP headers of encapsulated packets.

If multiple interfaces have referenced an IPsec policy that is bound to a source interface, you must use the

same DF bit setting on these interfaces.

Examples

# Set the DF bit for outer IP headers of encapsulated IPsec packets on VLAN-interface 1.

<Sysname> system-view

[Sysname] interface vlan-interface1

[Sysname-Vlan-interface1] ipsec df-bit set

Related commands

ipsec global-df-bit

Use

ipsec global-df-bit

Use

undo ipsec global-df-bit

to restore the default.

Syntax
