FIRMWARE CHANGES AND ENHANCEMENTS:
The following Known Issues have been fixed in this release of firmware.
1. This version of code corrects a condition that has been occasionally seen in the VH-2402S causing the units
to randomly reset.
2. This version of code corrects a condition that has been occasionally seen in the VH-2402S causing all ports
to enter a non-forwarding state. All packets that are transmitted into any port(s) on the switch are counted as
dropped.
3. This version of code corrects a condition that could be seen in networks with high rates of varied types of
broadcast traffic. This caused the units to enter a port lock up state. During this state, some ports would stop
forwarding traffic and others would not.
4. This version of firmware supports a reduced boot up time when the system(s) is warm restarted.
When restarting the system, select ‘NO POST’ from the console for faster system boot up. This
enhancement enables the VH-2402S to bypass the internal diagnostics (POST) during a system restart. For
a single unit, the boot time is reduced from approximately 210 seconds to 90 seconds.
5. HTTP POST packets will no longer cause the switch to lock up and unwanted HTTP POST packets will be
dropped.
6. Auto-Negotiation on the VHIM1000-S1SX uplink module has been changed to address the link up issues that
could occur when two Vertical Horizon switches containing interconnected VHIM1000-S1SX modules are
powered up simultaneously.
7. Support for the VHIM1000-S1TX 1000Base T uplink module has been added.
8. Broadcast Storm Protection (previously Broadcast Strom Control) h
as been changed to reflect the following:
The user selectable Threshold setting is now between 100 and 141,000 pps in increments of 100. The
default is 200pps. The user selectable Average Intervals are 200ms, 500ms, 1sec, 5sec and 10sec. The
default is 1sec. This new algorithm ensures that high raters of broadcast traffic will not hinder the operation
