In our last bog, I hinted about a network TAP that could not only be connected to an inline appliance without introducing a point of failure, but also be connected to one or two network analyzer tools or provide a High Availability (HA) scenario for the inline appliance to provide protection to your critical link.
Well, today we are going to introduce you to the integrated 8 port inline network TAP.
I borrowed Figure 1 from our last blog on Bypass TAPs as a place to start my discussion.
The network TAP we will discuss today can do all the things that our inline Bypass TAP can do, also referred to as a "bypass switch."
It can provide access to an inline appliance without introducing a point of failure, as well be used as a Breakout TAP or an Aggregating TAP. Unfortunately, it can’t be a bypass TAP and a Breakout TAP at the same time. The only way to see the traffic in the critical link would be to:
It is not the best solution because it does introduce a tiny bit more latency into the link. That’s where the INT1G8 integrated TAP enters the scene. It does away with the latency that option B introduces because the link does not have to be tapped a second time and still maintains the FailSafe that is required in case the network TAP should lose power.
Figure 2 shows that the INT8 provides the same functionality of the Bypass TAP that you see in Figure 1. But, as you can see, there are a few ports that are not needed to provide the functionality of the Bypass TAP in Figure 1. It is those few ports that provide a whole new set of solutions to safeguard your critical links that were not available until the introduction of the INT8.
The scenario in Figure 3 adds a second inline appliance to provide backup to the active inline appliance. If appliance A (active appliance) needs to be taken offline for software upgrades, the TAP will automatically switch over to appliance B to keep monitoring the critical network. If appliance B should lose power, while appliance A is still offline, the appliance is bypassed and the critical link is maintained. But there are still a couple more ports available. These ports can be used to attach a network analyzer or deep capture engine to provide even more visibility into the Critical Link.
Another Scenario using the INT8 is in a HA network with HA appliances. If Appliance A is taken off-line on the primary side, the TAP will switch over to Appliance B. Should the Primary Network fail, the Primary Network will failover to the Secondary side, where it will still rout traffic to In-Line Appliance A. As it was on the Primary side, if Appliance A is taken off line, the secondary TAP will switch over to the In-Line Appliance B. I like to call this the Bullet Proof Solution.
Notice in each figure, ports G and H are available. These ports can be used as breakout TAP monitor ports to a diagnostic tool or as two aggregated monitor ports out to two diagnostic tools. If you only need a single Bypass operation, then ports E and F are also available to become monitoring ports for yet another diagnostic tool.
So if you need a Bypass TAP that can multitask, or any of the network TAPs that were covered in this series, talk to us. I’m sure we can find a way to solve your network access problems. And don’t forget, we do all this without introducing a “Point of Failure.”
