SNMP
Vbrick supports SNMP v2 and SNMP v3 traps. SNMP traps are a subset of the SNMP
management component of the appliance. Use of any element of the SNMP management
system requires use of an SNMP browser or SNMP manager application (not supplied).
Traps are SNMP base messages used by SNMP elements to report changes in status or alarm
conditions to remote SNMP management entities. Traps are generally used to alert network
administrators of potential equipment problems or other noteworthy events. The trap event
will be sent every time the monitored event occurs and then not again unless the condition
goes away and returns or if SNMP is restarted or reconfigured on the DME.
Currently defined traps are sent with the root Vbrick OID of 1.3.6.1.4.1.4289 with text
indicating which trap it is.
Vbrick supports read-only access to the following standard MIBs (DMEs currently support
MIB-I, but not MIB-II/MIB-2 standards):
•
HOST-RESOURCES-MIB (.1.3.6.1.2.1.25.)
• UCD-SNMP-MIB (.1.3.6.1.4.1.2021.)
• IP-MIB (.1.3.6.1.2.1.4.)
• IF-MIB (.1.3.6.1.2.1.2.)
RTMP Announce
Receiver Default = Enabled.
Flash Server
Authentication Default = Enabled. If enabled, then RTMP streams pushed to the
DME must be authenticated using credentials on the
Stream Input
Authentication
screen. If disabled, then any RTMP stream can be
pushed to the DME without authentication being required.
Note: As always, it is recommended that you modify the default
passwords.
Serve HTTP/HLS
Videos This setting controls how HTTP content, e.g. HLS, will be delivered.
The default setting is to allow either HTTP or HTTPS delivery. It
should be noted that VEMS will utilize HTTP, On Premises Rev
(depending on configuration) may use either HTTP or HTTPS, and
Cloud Rev requires HTTPS for the player. Changing from this
default is not recommended.
TLS Support Use this dropdown to select the level of TLS support you want the
DME to use.
Cache Manager Utility Default = Disabled. For debugging only.
Note: The VBAdmin UI utilizes the Linux free command to determine
memory usage (free and swap). This is a different calculation of memory
than is reported by the UCD-SNMP-MIB (which does not include slab
allocation in cache). For more accurate free physical memory, you may wish
to consider tracking the sum (memAvailReal.0 + memBuffer.0 +
memCached.0) – also still lower than what is reported by free. This also
affects HOST-RESOURCES-MIB. Please be aware of this and review if you
are using SNMP to track memory via either of these MIBs.
