CISCO-VISM-CODEC-MIB.mib object view, vendor Stratacom
Introduction
Most network devices and programs ship with so-called MIB files to describe the parameters and meanings (i.e.: friendly names) which are available for monitoring via SNMP.
ActiveXperts Network Monitor 2024 can import vendor-specific MIB files, so it can be used to monitor specific OID's (Object Identifiers).
This way, you can monitor your devices, computers, etc. by selecting your relevant OID's by name.
ActiveXperts Network Monitor 2024 can import MIB file CISCO-VISM-CODEC-MIB and use it to monitor vendor specific OID's.

Object view of CISCO-VISM-CODEC-MIB:
Scalar Object |
vismCodecCnfEntry |
.1.3.6.1.4.1.351.110.5.5.18.1.1 |
An entry in the vismCodecCnfTable contains
packetization period information for a specific codec.
These entries are created by the agent when the card
comes up with appropriate default values and the user
can modify the packetization period for a particular
codec any point in time.
|
vismCodecTemplateCnfGrpEntry |
.1.3.6.1.4.1.351.110.5.5.7.1.1 |
An entry is defined for each set of codecs supported.
The codecs supported are a combination of :
G.711Mu (PCM - Mu-law)
G.711A (PCM - A-law)
G.726/32 (ADPCM)
G.729a (CS-ACELP - Annex A)
G.729ab (CS-ACELP - Annex B)
clearChannel (clear channel voice)
G.723.1-H

|
vismCodecName |
.1.3.6.1.4.1.351.110.5.5.18.1.1.2 |
This object holds the name of a codec. For example,
index 1 will have G.711u as the codec name
index 2 will have G.711a as the codec name and so on.
|
vismCodecPktPeriod |
.1.3.6.1.4.1.351.110.5.5.18.1.1.3 |
This object gives the packetization period for a
particular codec.
for G.711u allowed values are 10 & 20
for G.711a allowed values are 10 & 20
for G.726 at 32 kbps allowed values are 10, 20, 30 & 40
for G.729a allowed values are 10, 20, 30 & 40
for G.729ab allowed values are 10, 20, 30 & 40
for clear channel allowed values are 10 and 20
for G.726 at 16 kbps allowed values are 10, 20, 30 & 40
for G.726 at 14 kbps allowed values are 10, 20, 30 & 40
for G.726 at 40 kbps allowed values are 10, 20, 30 & 40
for G.723 allowed values are 30 & 60
for Lossless allowed values are 10 and 20
Default value for G.723 is 30, for other codecs it is 10.
|
vismCodecPreference |
.1.3.6.1.4.1.351.110.5.5.18.1.1.4 |
This object contains the user configured preference for
each codec. Lower the number, higher the preference of the
codec.
If the call agent does not specify the preferred codec list
in CRCX(CreateConnection) request then the codec used
will be the one of highest preference, as configured
in this object.
The default preference based on the codec type is
G729ab will have preference 1
G729a will have preference 2
G726 at rate 16 kbps will have preference 3
G726 at rate 24 kbps will have preference 4
G726 at rate 32 kbps will have preference 5
G726 at rate 40 kbps will have preference 6
G.711u will have preference 7 for T1 and will have
preference 8 for E1
G.711a will have preference 7 for E1 card and will
have preference 8 for T1
clearChannel will have preference 9
G723H will have preference 10
G723AH will have preference 11
G723L will have preference 12
G723AL will have preference 13
Lossless will have preference 14
If the preference of a codec is zero then that codec
will not be used.
|
vismCodecString |
.1.3.6.1.4.1.351.110.5.5.18.1.1.5 |
The local connection option or SDP(Session Description
Protocol) descriptor string that VISM would get from
the call agent for the codec to be used will be
in the form of PCMU, PCMA, G726 at rate 32 kbps,
G729a, CCD .....
where in PCMU stands for G711u
PCMA stands for G711a
and CCD stands for clear channel
This object serves as a mapping string, and VISM will use the
value configured in this object to match the SDP
descriptor string obtained for a codec in a CRCX
or MDCX(ModifyConnection) message.
Since the entries in this table are implicitly created
by default the entry with codec =
G.711u will have a value of PCMU
G.711a will have a value of PCMA
clear channel will have a value of CCD
G.726 at rate 32 kbps will have G726 at rate 32 kbps
G.726 at rate 16 kbps will have G726 at rate 16 kbps
G.726 at rate 24 kbps will have G726 at rate 24 kbps
G.726 at rate 40 kbps will have G726 at rate 40 kbps
G.729a will have G729a
G.729ab will have G729ab
G.723.1-H will have G723H
G.723.1a-H will have G723AH
G.723.1-L will have G723L
G.723.1a-L will have G723AL
Lossless will have Lossless
|
vismCodecIanaType |
.1.3.6.1.4.1.351.110.5.5.18.1.1.6 |
This object specifies the payload types (PT) of
a codec. PT numbers for CODECS are assigned by
IANA(Internet assigned number Authority).
If in a SDP string we would just receive an IANA type
number and not the codec string, then VISM would use
the value in this object to derive the actual codec
to be used in the bearer path.
|
vismCodecTemplateNum |
.1.3.6.1.4.1.351.110.5.5.7.1.1.1 |
This attribute defines the index for the CodecTemplate
table. Template number is input at the time of configuring
a template using 'cncodectmpl' CLI command.
|

.1.3.6.1.4.1.351.110.5.5.7.1.1.2 |
This attribute represents a bit map of Codecs supported
in this template.
Bit 0 - represents the G.711 Mu-law codec.
Bit 1 - represents the G.711 A-law codec.
Bit 2 - represents the G.726 at rate 32 kbps.
Bit 3 - represents the G.729a codec.
