Chapter 1 Overview
Supported Protocols
Cisco Memory Pool MIB
This MIB allows detailed information to be retrieved for all memory pools present
within a Cisco device. The VG248 implements this MIB, but because all dynamic
memory management uses a single heap, the resulting table has one row, which is
returned as “Processor”.
Cisco EnvMon MIB
“EnvMon” refers to the on-board environmental monitor on the VG248 that
monitors the internal voltage, power supply, temperature, and fan settings.
The VG248 routinely measures these values recording the information in the rows
within the different tables:
•
ciscoEnvMonVoltageStatusTable—records voltage and power supply
readings
•
ciscoEnvMonFanStatusTable—records fan status readings
•
ciscoEnvMonTemperatureStatusTable—records temperature settings
You can use this MIB to access these recorded values. Also, if the VG248 detects
readings beyond the acceptable limits, the device generates warning messages.
See the
“Troubleshooting Hardware Errors” section on page 6-1
for details.
Cisco Voice Interface MIB
This Cisco proprietary MIB (
CISCO-VOICE-IF-MIB.my
) allows access to
voice interface parameters such as gain values and echo cancellation status. The
VG248 implementation of this MIB provides read access only. You can configure
the gain values using the VG248 interface (see the
“Setting the Output Gain”
section on page 3-13
and the
“Setting the Input Gain” section on page 3-14
for
details).
Cisco Analog Voice Interface MIB
This Cisco proprietary MIB (
CISCO-VOICE-ANALOG-IF-MIB.my
) allows
access to interface parameters related to the analog ports. These parameters
include hardware issues such as electrical impedance value and ring frequency
and user factors such as whether an attached handset is currently on- or off-hook.
The electrical impedance value and ring frequency is determined by the country
code you set in the VG248 (see
“Identifying the Country Code for VG248”
section on page 3-6
for details). You can modify the hook-flash timer using the
VG248 interface (see
“Changing the Hook Flash Timer for Analog Phones”
section on page 3-7
).
