This command is used to perform incremental update of ACL rule table. This command gets existing rules from Config DB and compares with rules specified in input file and performs corresponding modifications.
With respect to DATA ACLs, the command does not assume that new dataplane ACLs can be inserted in betweeen by shifting existing ACLs in all ASICs. Therefore, this command performs a full update on dataplane ACLs.
With respect to DATA ACLs, the command does not assume that new dataplane ACLs can be inserted in between by shifting existing ACLs in all ASICs. Therefore, this command performs a full update on dataplane ACLs.
With respect to control plane ACLs, this command performs an incremental update.
If we assume that "file1.json" is the already loaded ACL rules file and if "file2.json" is the input file that is passed as parameter for this command, the following requirements are valid for the input file.
1) First copy the file1.json to file2.json.
2) Remove the unwanted ACL rules from file2.json
3) Add the newly required ACL rules into file2.json.
4) Modify the existing ACL rules (that require changes) in file2.json.
NOTE: If any ACL rule that is already available in file1.json is required even after this command execution, such rules should remain unalterted in file2.json. Don't remove them.

Note that "incremental" is working like "full".

## BGP
This section explains all the BGP show commands and BGP configuation commands in both "Quagga" and "FRR" routing software that are supported in SONiC.
In 201811 and older verisons "Quagga" was enabled by default. In current version "FRR" is enabled by default.

In 201811 and older versions "Quagga" was enabled by default. In current version "FRR" is enabled by default.
Most of the FRR show commands start with "show bgp". Similar commands in Quagga starts with "show ip bgp". All sub-options supported in all these show commands are common for FRR and Quagga.
Detailed show commands examples for Quagga are provided at the end of this document.This section captures only the commands supported by FRR.
