Hi all,

I have NCS5508, when i check the command below

sh controllers npu resources encap location 0/0/CPU0

sh controllers npu resources encap location 0/1/CPU0

I found the below

urrent Hardware Usage
Name: encap

Name: bank_0
Estimated Max Entries : 4096
Total In-Use : 4096 (100 %)
OOR State : Red
OOR State Change Time : 2022.Jan.05 07:12:02 UTC
Bank Info : phase=2 extended=no

my questions as below

1- What is meaning encap

2- What is the main function of encap

3- Why Total In-Use : 100% , how can reduce it

4- What we mean by bank_0 , bank_1 , bank_2 etc.

I attached the show output file .. Thanks in advance

Kind Regards
