There are two primary components of an ACL: 



 

Rule: A single ACL consists of one or more ACL rules. As discussed earlier, the rule is a filter configured to 

take a specific action on packets matching specific criteria. Up to 128 rules can be configured per ACL. 

Each rule specifies the action to take when a packet matches the specifies criteria. This section discusses the 
rule actions and criteria supported by the system. 



 

Rule Order: A single ACL can consist of multiple rules. Each packet is compared against each of the ACL rules, 

in the order in which they were entered, until a match is found. Once a match is identified, all subsequent rules 
are ignored.

System Administration Guide. 

The system's support for bulk statistics allows operators to choose to view not only statistics that are of importance to 
them, but also to configure the format in which it is presented. This simplifies the post-processing of statistical data 
since it can be formatted to be parsed by external, back-end processors. 

When used in conjunction with the Web Element Manager, the data can be parsed, archived, and graphed. 

The system can be configured to collect bulk statistics (performance data) and send them to a collection server (called a 
receiver). Bulk statistics are statistics that are collected in a group. The individual statistics are grouped by schema. 
Following is a partial list of supported schemas: 



 

System: Provides system-level statistics 



 

Card: Provides card-level statistics 



 

Port: Provides port-level statistics 



 

MME: Provides MME service statistics 



 

GTP-U: Provides GPRS Tunneling Protocol - User message statistics 



 

HENBGW-ACCESS: Provides HeNB-GW access side statistics 



 

HENBGW-NETWORK: Provides HeNB-GW network side statistics 

The system supports the configuration of up to 4 sets (primary/secondary) of receivers. Each set can be configured with 
to collect specific sets of statistics from the various schemas. Statistics can be pulled manually from the chassis or sent 
at configured intervals. The bulk statistics are stored on the receiver(s) in files. 

The format of the bulk statistic data files can be configured by the user. Users can specify the format of the file name, 
file headers, and/or footers to include information such as the date, chassis host name, chassis uptime, the IP address of 
the system generating the statistics (available for only for headers and footers), and/or the time that the file was 
generated. 

When the Web Element Manager is used as the receiver, it is capable of further processing the statistics data through 
XML parsing, archiving, and graphing. 

The Bulk Statistics Server component of the Web Element Manager parses collected statistics and stores the information 
in the PostgreSQL database. If XML file generation and transfer is required, this element generates the XML output and 
can send it to a Northbound NMS or an alternate bulk statistics server for further processing.
