Why disable waas

Applying a WAAS policy to an interface. Specifying traffic processing slots for an interface. Configuring WAAS to operate in asymmetric mode. Configuring TFO parameters. Configuring the TFO blacklist autodiscovery feature.

Configuring DRE optimization parameters. Configuring UDP log message compression or decompression. Restoring predefined WAAS settings. Deleting all WAAS settings. Enter system view. Configure a match criterion.

To configure a WAAS policy, perform the following tasks:. Create a WAAS policy. Configure actions for the WAAS class. You can configure the following actions for a WAAS class:. For an optimization action to take effect, you must enable the corresponding optimization feature. Configure optimization actions or the passthrough action.

Return to system view. Enable DRE. Enable LZ compression. The device optimizes or passes through the traffic entering and leaving the WAN according to the configured policy.

If the incoming and outgoing interfaces of the traffic are both connected to the WAN, the traffic is not optimized. A WAAS policy can be applied to multiple interfaces. Only one WAAS policy can be applied to an interface. Enter interface view. Apply a WAAS policy to the interface.

By default, no WAAS policy is applied to an interface. If a logical interface that spans cards or IRF member devices acts as a WAN interface, specify the slot of any member port in logical interface view as its traffic processing slot. For high availability, you can specify one primary and one backup traffic processing slot by using the service command and the service standby command, respectively.

The primary and backup slots must be different slots. If you specify both primary and backup slots, the backup slot takes over when the primary slot becomes unavailable. The backup slot continues to process traffic for the interface after the primary slot becomes available again. The switchover will not occur until the backup slot becomes unavailable. When both primary and backup slots are unavailable, the traffic is processed by the slot at which it arrives.

The specified processing slot that first becomes available again takes over. To avoid processing slot switchover, specify the primary slot before specifying the backup slot.

If you specify the backup slot before specifying the primary slot, traffic is switched over to the primary slot immediately after you specify the primary slot. Specify the primary traffic processing slot for the interface.

By default, no primary traffic processing slot is specified for an interface. Specify the backup traffic processing slot for the interface. By default, no backup traffic processing slot is specified for an interface. If the device sends and receives packets on the same interface, the device should operate in symmetric mode.

Perform this task if the device sends and receives packets on different interfaces. Configure WAAS to operate in asymmetric mode. The congestion window size changes with the congestion status and transmission speed. An appropriate initial congestion window size can quickly restore the network to its full transmission capacity after congestion occurs. If the local device does not send or receive any data when the timer expires, it sends a keepalive to the peer to maintain the connection.

The receiving buffer size specifies the size of data that can be received. It affects network throughput. Different network performance requirements require different TCP congestion control algorithms.

Selecting a proper TCP congestion control algorithm enables a network to quickly recover to the maximum transmission capacity. After the maximum number of concurrent connections is reached, WAAS does not optimize traffic for newly established connections. Set the initial congestion window size. Enable TFO keepalives.

Set the receiving buffer size. Set the maximum number of concurrent connections. As a best practice, use a higher-level offset step on high-speed links to improve match efficiency. Use a lower-level offset step on low-speed links to ensure match precision. If the number of data dictionary entries reaches the limit, the device no longer creates new entries.

The amount of time used by the device to poll all data dictionary entries depends on the number of data dictionary entries on the device. Set the DRE match offset step. The default setting is normal. The following DRE match offset step levels are listed from high to low:.

Set the aging time for data dictionary entries. Connect and share knowledge within a single location that is structured and easy to search. The ADS-B will continue to function as in send messages but the position reports will be unavailable. It's important to note that your transponder is still a Mode-C transponder, even if the ADS-B fails completely or partially.

Really though as far as this is concerned, creating an actual failure is very much not recommended. It might be a "teachable" moment at first, but really just creates a distraction that can be done in other ways.

What happens if the circuit breaker fails and the weather actually drops? Now you have a real problem Note: For the Airborne Position Message, altitude data alone is sufficient to maintain broadcast of the Message once the Message has been initiated. When only altitude data is available, the Airborne Position Message continues to be transmitted even after 60 seconds.

Interestingly, however, there are additional messages e. So, one could say that you have a properly certified ADS-B transmitter installed, you are operating it in transmit mode, and it is actually broadcasting messages; therefore you are in compliance with the rule. Two points - 1. Compliance with So, while the OP may be compliant with the equipment requirement of Sign up to join this community. I was looking at 8' error circles with my V's quad antenna and in the car with an outboard patch.

I never get lost everybody keeps telling me where to go. They are transmitting most of the time already, but with a "Don't use" status signal. Magellan receivers don't care about that the signal isn't reliable, they use it anyway.

A Garmin receiver, however, refuses to use the signal until its status has been raised to the "OK for test" level. They did try it on November 25th. The epe your gps gives you is not a true indicator of how accurate your fix is.

It is just an estimation based primarily on satellite geometry. When SA was turned off the epe on Northstar X gpsr's did not change. They still show epe's of around ft. The programmers never changed the bogus algorithim that determined epe. They should do away with that feature. It only confuses people. If a gps new how much in error the position is, then why doesn't it just apply the correction?

Because it doesn't really know how much in error it is, it just gives you a best guess. Which is useful to some degree but too many people take it as an absolute figure. In Indiana I can usually get all "D"'s on the status bars since there is so much open space in rural hoosier land.

I like having 8' accuracy showing on my screen even if it doesn't help find caches since most cache placers don't use waas. I 've heard those claims enough that I really don't doubt they're true. I've gone on 12 hour GPS hunts on the same set of batteries rechargables. As long as it doesnt' drain my batteries while I'm hunting I'm happy. It can take up to 20 minutes for WAAS to start doing it's thing.

When I start off on road trips it usually takes 10 minutes after powering up before the accuracy drops dramatically. You can post now and register later.
