User manual

The WebMux™ Model 480S, 580SG, and 680PG User Guide – Version 7.0.x

or computers behind WebMux™. WebMux™ does not have the

management functionality for restricting which IP address or services

an internal host can reach to the outside. If such restriction is

desirable, then additional firewall is needed.

Q. What can I do if the service that I want to load balance is not in the list?

R. WebMux™ as is already supports many different services. In the case

if your service is not in the list, you could use generic TCP and/or UDP

to set your farm. If that is still not good enough, you may contact us for

developing a special service aware module for you. In most cases,

there is a very reasonable fee to be charged.

Q Why secondary WebMux™ did not take over when I powered down

Primary WebMux™?

R 1) Two WebMux™ not on the same version of firmware. Or 2)

Secondary WebMux™ monitors primary WebMux™ as well as few

other things. Before it takes over, it makes sure it can reach to the

router LAN gateway, as well as at least one server defined in any farm.

If secondary WebMux™ cannot reach to the front router LAN gateway,

or it cannot see any server in any farm, then it will consider the primary

disconnect or power down was done purposely by operator.

Q Why my FastIron Switch set to 100MB fix speed does not work with

WebMux™?

R WebMux ™ uses Intel network chipsets internally. Intel chipsets

follows all industrial standards and have good performance and

reliability. However, we did discovered some of the Foundry Networks

switches does not negotiate with Intel chipsets well. To make them

work together, one will need to set the switch to “auto negotiation” on

speed, instead of fixed 100. They will communicate each other at

100BT or 1000BT (Pro version only).
