SNMP MIB browser not displaying information on VLAN-related OIDs

For Windows systems, when a large number of VLANs are created on a port, the SNMP MIB browser
sometimes doesn't display the requested info for snmp_getBulk/snmp_walk/snmp_table
operations on VLAN-related object identifiers (OIDs). Instead a "Failed to connect to the SNMP
agent" message displays.
Possible Cause: The browser is timing out before all data is populated.
Possible Cause: Increase the default timeout value of the SNMP MIB browser to a sufficiently large
value (40 seconds - 50 seconds) so that all the values populate before time-out.

Teaming errors

Ports configured as team members are in an error state and output from the BCU team --vlanquery
command shows mismatching of teaming parameters. Although you can still create teams, the
parameters configured for the first port (primary port) added to a team should match parameters
of subsequent ports added to the team or mismatching conflict errors result.
In the following example output from the BCU team --vlanquery command, a conflict displays for the
port associated with local area connection 6 because its PVID does not match the PVID of the
primary port (local area connection 3).
2/0 : Local Area Connection 3 (Primary) (Active) (Linkdown)
3/1 : Local Area Connection 6 )Conflict)
Conflict Reason: Mismatching PVIDs configured for adapters
Note that you can still create teams even though these conflicts exist. However to avoid conflicts,
make sure the following parameters match for all ports added to a team:

Applications that use the TDI driver for network traffic may stop responding on Windows Server
2008 and Windows Vista systems.
Possible Cause: Windows hotfix KB2029048 is not installed.
Action: Download and install hotfix KB2029048. This hotfix is optional.
Receive-side scaling (RSS) network throughput performance decreases on Windows Server
2008 R2 systems with more than 32 processors.
Possible Cause: Windows hotfix KB977977 is not installed.
Action: Download and install hotfix KB977977. This hotfix is recommended.
