Hello community,

 

Can anyone explain to me the bellow point :

 

show hardware access-list resource utilization
slot  1
=======



INSTANCE 0x0
-------------


         ACL Hardware Resource Utilization (Mod 1)
         ----------------------------------------------------------
                                        Used    Free    Percent 
                                                        Utilization
------------------------------------------------------------------- 
Ingress L2 QOS                          240     16      93.75
 Ingress L2 QOS IPv4                    240             93.75
 Ingress L2 QOS IPv6                    0               0.00
 Ingress L2 QOS MAC                     0               0.00
 Ingress L2 QOS ALL                     0               0.00
 Ingress L2 QOS OTHER                   0               0.00

         ACL Hardware Resource Utilization (Mod 1)
         ----------------------------------------------------------
                                        Used    Free    Percent 
                                                        Utilization
------------------------------------------------------------------- 
Ingress L2 QOS                          8       248     3.12
 Ingress L2 QOS IPv4                    8               3.12
 Ingress L2 QOS IPv6                    0               0.00
 Ingress L2 QOS MAC                     0               0.00
 Ingress L2 QOS ALL                     0               0.00
 Ingress L2 QOS OTHER                   0               0.00

What is the deference between INSTANCE 0x0 and INSTANCE 0x1 ?

and as you can see Ingress L2 QOS USed = 240 and Free = 16.

what is behind this 240 entry ? a MAC address ? a QoS applied on an interface ? what changes should be done on this switch to get L2 QOS USed = 241 and Free = 15. to better understanding,

 

Thank you
