Supported Protocols

Interface MIB
This MIB is defined in RFC 1573 and extends the range of information available
about a device's interfaces from that provided by the ifTable in RFC 1213. The
VG248 implements this MIB for its Ethernet interface and the 48 FXS interfaces.
However, the octet or packet count values are not available for the FXS interfaces
because they are not applicable to these interface types.
RMON
The VG248 implements the Ethernet Statistics group in Remote Monitoring
(RMON), with the exception of "EtherStatsStatus." This is fixed at "valid" and
cannot be written.
Cisco CDP MIB
Cisco Discovery Protocol (CDP) is a method that Cisco devices use to advertise
their presence and to discover information about other nearby devices. The
VG248 supports CDP and implements this MIB. You can enable or disable CDP
on the VG248. See the
Cisco Process MIB
This MIB describes the processes currently running on the device. However,
because the VG248 runs threads, rather than processes, the MIB is implemented
with the following caveats:

No "ip***" values can be written.
You cannot write to "tcpConnState" for an active TCP connection.
The VG248 does not implement the External Gateway Protocol (EGP).
"Enabling CDP" section on page 2-10
The amount of memory allocated is not recorded on a per-thread basis.
Therefore, cpmProcExtMemAllocated and cpmProcExtMemFreed are
returned as 0.
All threads run at the same priority. Therefore, every process
cpmProcExtPriority are returned as "normal."
It is not possible to change a process's priority, so attempts to write
"cpmProcExtPriority" are unsuccessful.
