2. Configure the DF bit of
IPsec packets globally.
ipsec global-df-bit { clear | copy | set }
By default, IPsec copies the DF bit
in the original IP header to the
new IP header.
Displaying and maintaining IPsec
Execute display commands in any view and reset commands in user view.
Task Command

IPsec configuration examples
Configuring a manual mode IPsec tunnel for IPv4 packets
Network requirements
As shown in Figure 57, establish an IPsec tunnel between Switch A and Switch B to protect data flows
between the switches. Configure the tunnel as follows:
• Specify the encapsulation mode as tunnel, the security protocol as ESP, the encryption algorithm as
AES-CBC-192, and the authentication algorithm as HMAC-SHA1.
• Manually setup IPsec SAs.
