Ieee Standards Support - Enterasys Vertical Horizon VH-2402S Release Notes

The Root Port Cost on a Trunk will change back to the Default Port Cost (i.e., 15) after a respan or a reboot of
the VH-2402S/VH-2402S2.
Under high broadcast loads, the VH-2402S/VH-2402S2 implements internal mechanisms to limit broadcast and
multicast traffic to the Management Agent. This filtering of traffic to the CPU may cause the CPU not to see the
IGMP streams for a group for which no "join" messages have been received. The outcome of this event is
flooding of the multicast stream until either a "Join" (or "Leave") message is received or until the broadcast and
multicast traffic is reduced to a small enough level that the Management Agent can process all of them.
The VH-2402S2 Filtering Database supports up to 8,000 entries compared to the VH-2402S Filtering Database
which supports up to 12,000 entries due to internal chipset memory limitations. While the actual internal memory
is slightly smaller in the new chip because of the sparse hashing mechanism used, it is often possible to have
many more than 8000 table entries.
If a Static Router port is configured on a multi-port trunk (link aggregation group), it may not be saved following a
reboot of the VH-2402S/VH-2402S2. Note: Static Router ports on other ports are not lost after a reboot. This
issue will be fixed in a future release.
When VLANs are added in the Port Assignment VLAN Config View, they will not be saved following a reboot
until the CPU Agent has had time to place them in NV-RAM. After configuring the Ports with VLANs, wait 5
Minutes before rebooting the Switch.
EMAN 3.0 Java Chassis Manager works properly, but at times it may not properly "draw" the VH-2402S2 Stack.
Work-around:
1. Add the following line to the <install>/Resources/ChMgr.ini file under [ChMgrLayouts]
etsysOidDevVHx2402S2=7
2. Add the enterasys-oids-mib to the EMAN 3.0 MIB database.
While a TFTP configuration upload is being done, an image download of new firmware cannot be done at the
same time. The new firmware can be downloaded as soon as the TFTP configuration upload has finished.
When modifying Speed/Duplex and Flow Control parameters on more than 8 Ports within the Port Configuration
View, only the Speed/Duplex values will be saved after clicking on <OK> or <APPLY>.
Other Known Issues and Restrictions can be found in the VH-2402S v02.05.00 Release Notes. Any problems
other than those listed above should be reported to our Technical Support Staff.
