EPICenter Release Note

Telnet Polling and EPICenter

Although EPICenter primarily uses SNMP to retrieve switch status and configuration information, it

uses Telnet polling to collect certain types of information that are not available using SNMP. This

includes information about netlogins, device FDB data (if FDB polling is enabled) and other selected

status. EPICenter’s use of Telnet polling can affect your switches in several ways:

● Each time EPICenter logs in and out of the switch, entries are created in the switch log.

● In some cases EPICenter needs to disable CLI paging in order to parse the results of certain

commands. This creates an entry into the switch log file each time this occurs.

● Over time, these entries can fill the switch log file, and can make it more difficult to recognize log

entries due to errors or other significant conditions. If these entries in the log file become

problematic, there are several possible steps you can take to alleviate the problem, including

periodically clearing the switch log, disabling EPICenter’s Telnet polling, reducing EPICenter’s

polling frequency, or using the ExtremeWare or ExtremeXOS Event Management System log filtering

capability to suppress the log entries generated by EPICenter login and logout events. For details on

implementing any of these tactics, see the EPICenter Concepts and Solutions Guide.

EPICenter Server Requirements

The EPICenter 7.0 server is supported on Windows Vista, XP, or 2003 Server, on workstations running

Solaris 10, or on systems running Red Hat Enterprise Linux version 5.

Specific details as to versions supported, as well as hardware and software requirements, are described

in the following subsections.

NOTE

Prior to installing EPICenter, make sure the system where you are installing the software is DNS-resolvable and

accessible both by IP address and by hostname from all machines where the EPICenter client will be launched. If it

is not, add an entry for the system in the local DNS server or the hosts file on the client machines.

Microsoft Windows Vista/XP/2003 Server

The system requirements for the EPICenter server under Microsoft Windows are as follows:

● Microsoft Windows Vista, Windows XP Professional with SP1 or later, or Windows 2003 Server

running on an Intel Pentium-compatible CPU.

● 1 GB RAM minimum, 2 GB recommended.

If the Gold upgrade license is installed to allow up to 2,000 devices, up to 2 GB may be needed for

very large numbers of devices (1000 or more).

● 2 GB disk space available, NTFS filesystem recommended.

● Swap space equal to double the amount of memory. For example, if you have 512 MB of RAM, you

should have 1 GB of swap space.

● 1 GHz or greater Pentium-compatible processor (2 GHz recommended).

The EPICenter server software requires the 1.6.0_10 Java runtime package, which is included in the

server installation. No separate installation is needed.
