Symantec endpoint protection clients not updating from management server internet dating wifes
If you have an environment where you have a separate Live Update in your environment, the GUPs will not request definitions from this system.
Depending on how clients are chosen to be GUPs, the antivirus team will need to be aware of any system decommissions.
If the client is not able to download the definition from the GUP due to the amount of time it takes or if the GUP is unavailable, it will then default to pulling definitions from the SEPM.
This is to insure that definitions are available to the client even if GUPs are unavailable. To understand the bandwidth savings of using a GUP it is important to understand the amount of traffic generated by definitions updates.
In some environments client communication will go over the WAN while Internet traffic will traverse through a cheaper local ISP.
In this scenario one serious discussion should be if it is better engineered to have all clients retrieve their definitions directly through the Internet to Symantec’s public Live Update servers.
If the GUP does not have a definition it will reach out to its defined SEP Manager and download the correct update.
On the next heartbeat interval the client will then download the definition from the GUP.
By default, SEP will use the operating system's proxy settings.Since differential updates are normally small, in an environment where all the traffic is on the same local LAN as the SEPM, it almost is never beneficial to use GUPs in this scenario.While some bandwidth could be recovered by putting a GUP on each subnet, the management of a large-scale GUP environment in a local LAN will likely take more time and effort than any nominal bandwidth savings.This is a scenario where some people could believe that the environment would act in a full peer-to-peer fashion.Since the controls are in place to insure that definitions originate from a SEPM to the GUP this will not occur.
On a subnet over a WAN link, you would have a single client retrieving definitions from the SEPM.
