HP 5900 switch reserved ACL resource

[JoonKim]

Hi,

I have a question with an HP 5900 switch. The exact model is HP 5900AF-48XG-4QSFP+ Switch (JC772A).

When I type "display qos-acl resource" command to display the resource usage, there is this "reserved" column which shows that the switch is reserving 1024 out of 2048 of IFP ACL resource total.

Is there a way to release this reserved resource, or anyway to change its value?  

[sw-of-inst-1]display qos-acl resource

Interfaces: XGE1/0/1 to XGE1/0/48, FGE1/0/49 to FGE1/0/52

This is something that pisses me off aswell...

Last update for A5820 (or if it was A5120) said that the firmware update upped number of ACLs from 1000 to 2000... at first I went "wohooo!" and then I found out the same as you...

This is the output of "display acl resource" on a A5820 (I have a few ACLs but its like less than 10 rows in total):

 Interface:
   XGE1/0/1 to XGE1/0/24, GE1/0/25 to GE1/0/28
---------------------------------------------------------------------
 Type          Total       Reserved    Configured  Remaining   Usage
---------------------------------------------------------------------
 VFP ACL       1024        256         0           768         25%
 IFP ACL       2048        1280        8           760         62%
 IFP Meter     1024        640         0           384         62%
 IFP Counter   1024        640         0           384         62%
 EFP ACL       512         0           0           512         0%
 EFP Meter     256         0           0           256         0%
 EFP Counter   256         0           0           256         0%

and here is the same thing from a A5120:

 Interface:
   GE1/0/1 to GE1/0/24
---------------------------------------------------------------------
 Type          Total       Reserved    Configured  Remaining   Usage
---------------------------------------------------------------------
 IFP ACL       2048        768         0           1280        37%
 IFP Meter     1024        384         0           640         37%
 IFP Counter   1024        384         0           640         37%

 Interface:
   GE1/0/25 to GE1/0/52, XGE1/1/1 to XGE1/1/2
---------------------------------------------------------------------
 Type          Total       Reserved    Configured  Remaining   Usage
---------------------------------------------------------------------
 IFP ACL       2048        768         2           1278        37%
 IFP Meter     1024        384         0           640         37%
 IFP Counter   1024        384         0           640         37%

Worth mentioning is that both A5820 and A5120 in my case have ipv6 enabled and the A5820 also have approx 100 vlan-interfaces configured with IPv6-addresses along with "ip urpf loose" in case any of this affects number of reserved ACLs (I have unfortunately no way to test this since I dont have any spare devices to test this on).
