Chapter 13
Configuring Hash Mode
If your diagnosis shows a performance degradation with an ACL enabled,
the IP Unicast Hash mode needs to be changed from DA-only to SA-DA.
When you enable an ACL, the switch automatically sets hash mode for IP
unicast traffic to SA-DA. This setting improves the performance of the
switch when an ACL is enabled.
This setting can cause a noticeable increase in the total flows identified and
result in an increased usage of F-chip memory. See “
Managing F-chip
Memory ” in this case.
* Important: Changing the Hash Mode setting affects every L3-
enabled F-chip on the P580 or P882.
