Only IPsec SAs negotiated by IKE support anti-replay checking. Manually created IPsec SAs do not
support anti-replay checking. Enabling or disabling IPsec anti-replay checking does not affect
manually created IPsec SAs.
Examples
# Enable IPsec anti-replay checking.
<Sysname> system-view
[Sysname] ipsec anti-replay check

Parameters
width
: Specifies the size for the anti-replay window. It can be 64, 128, 256, 512, or 1024 packets.
Usage guidelines
Changing the anti-replay window size affects only the IPsec SAs negotiated later.
Service data packets might be received in a very different order than their original order, and the
IPsec anti-replay feature might drop them as replayed packets, affecting normal communications. If
this happens, disable IPsec anti-replay checking or adjust the size of the anti-replay window as
required.
Examples
# Set the size of the anti-replay window to 128.
<Sysname> system-view
[Sysname] ipsec anti-replay window 128
