IP Address, Route, and Bandwidth Planning

IP Address, Route, and Bandwidth Planning

For service availability, you must properly plan IP addresses, routes, and bandwidth resources.

IP Address Planning

The IP address of the eLog analyzer or a collector must be planned before installation of the eLog. The IP address is used for the following functions:

  • Configuration and management of the eLog analyzer or collector.
  • External services of the eLog analyzer or collector. For example, the administrator accesses the eLog analyzer by using a Web browser; the eLog analyzer communicates with the collector

The principles for planning IP addresses are as follows:

  • The eLog supports only IPv4 addresses.
  • Only one IP address can be planned for each network port.
  • If the server has multiple network ports and is not configured with IP Network Multipathing (IPMP), the IP addresses configured for the network ports must be in different network segments.

    For example, if the IP address of the server is 192.168.1.1, the subnet mask 255.255.255.0 is and that of the gateway is 192.168.1.254; if the IP address of a collector is 192.168.1.10, the subnet mask is 255.255.255.0 and that of the gateway is 129.9.1.254.

Route Planning

Principle of route planning: The analyzer and collector are reachable. The collector and log source are reachable.

Planning the Bandwidth Between the Collectors and Log Sources

The bandwidth required for communication between the log collectors and log sources is high. Therefore, consider the following requirements during networking:

  • Session log bandwidth

    On max, a session log occupies 1800 bytes. The bandwidth required for a session log plus the network overhead is EPS x 1800 x 8 bit/s.

  • Syslog bandwidth

    The maximum size of a syslog is 1024 bytes. The bandwidth required for a syslog plus the network overhead is EPS x 1024 x 8 bit/s.

NOTE:

The sample value used in the previous estimation method is the average value in common scenarios. The log length in actual network environments probably differs from the sample value. Perform estimation based on the actual network condition. You are advised to keep bandwidth at 1 Gbit/s or higher for proper log transmission and receipt.
