Missed Browser Announcement

Counter

Missed Browser Announcement is a counter of events where the time elapsed since the last browser announcement exceeds a threshold. A count of all Missed Browser Announcement events displays in the Overview counters of Expert View.

Expert Symptom

Missed Browser Announcement events are automatically logged as expert symptoms. The Symptom Summary field provides the time elapsed since the last browser announcement compared to a threshold value. For example:

Time passed since last announcement=4000 ms (> 3000 ms)

The threshold value for this symptom can be changed. The default threshold value is multiplier of 2. The time interval to use is read from the announcement packet. For example, assume that the time-out value read from an SMB packet is 480,000 ms. If the multiplier value is set to 2, then the symptom displays when there is no browser announcement for 960,000 ms (2 X 480,000 ms).

Diagnostic Details

__________________________________________________________________

Problem Description:

No Browser announcement has been sent within the stated interval multiplied by the threshold value.

__________________________________________________________________

Probable Cause(s):

1.The network is overloaded so that the packets are lost.

2.The station has been shutdown.

__________________________________________________________________

Recommended Action(s):

1. Load balance your network.
