Bandwidthd complete practical notes

I. Network Configuration

Many Bandwidthd instances on the Internet are only installed with Bandwidthd. It is of little use to friends who are just doing network management. To use Bandwidthd for traffic monitoring, you must first understand your network topology and select an appropriate networking method.

Bandwidthd complete practical notes (PostgreSQL) _ 2

For example, the network topology I manage is as follows:

There are many access devices on the network, and the whole LAN accesses the Internet through the router for NAT. If Bandwidth is used for monitoring, the following two methods are available for networking.

Method 1: Add a server to the vro and firewall (or between your vro and intranet) (the server requires three NICS)

 

Method 2: If your core switch supports port mirroring, you can use Bandwidthd as a bypass for analysis.

 

Here, I chose 2nd solutions, and compared the server as the gateway, which is not very stable. If the server is dead, the entire network will be paralyzed.

If you select method 2, your core switch must support port mirroring.

The following is a brief introduction to my device list:

Router: H3C SR6604

Firewall: H3C SecBlade FW Firewall

Core switches: H3C7506, H3C7503, Huawei S6506, Huawei 5700

 

Specific operations:

Mirror the optical port of H3C7506 connected to the SR6604 router to the port connecting H3C7506 to the Bandwidthd server.

For example, you can create an image on the optical port to mirror traffic from G8/0/1 to G8/0/12.

Interface GigabitEthernet8/0/1
Port access vlan 3990
Speed1000
Duplex full
Grouping ing-group 1 grouping ing-port both

Interface GigabitEthernet8/0/12
Description mirror

Duplex full
Grouping ing-group 1 monitor-port
