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 affect only the IPsec SAs negotiated later.
In some cases, some service data packets might be received in a very different order than its original
order, and the IPsec anti-replay function might drop them as replayed packets, affecting the 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] ipsec anti-replay window 128
