Hi,
I have seen in the past but don't remember what did I change now, because this parameter is empty now.
Does anybody know how to configure that you could see/check the cfg file name and FW version from the CMTS?
show cable modem verbose | include "Configuration file name"
Configuration file name :n/a
show cable modem verbose | include "sysDescr"
sysDescr :n/a
I don't know what parameter must be added into the config file.
Thanks in advance, 0603
remote-query has to be enabled for that information to populate in the CMTS.
HM...and how to enable it?
I have configured SNMP access parameters in config file for pooling values and draw graphs.
But this is not the same or?
I have also configured remote-query on CMTS and the same SNMP community as for graphs but not success.
Any advice about what I am doing wrong?
Regards, 0603
what kind of CMTS are you using?
for a CASA it would look like this:
! cable modem remote-query configuration
cable modem remote-query 300 private
where 300 is the number of seconds to wait between polling and private is the snmp community the requests will be sent with. The modems have to be configured to respond to that community via modem config file
It is also important to set the interface the remote-queries will come from
cable modem remote-query loopback 0
Also make sure that your ACLs allow SNMP traffic from CMTS -> CM
you can manually trigger the remote-query by running:
show cable modem remote-query immediate
Remote Query is how the CMTS knows about:
Config File Name
sysDescr
DS Receive Power Levels/SNR (at the modem)
US Tx Power (at the modem)
for a Cisco CMTS the remote-query command is the same
snmp-server manager
cable modem remote-query 300 private
Same ACL recommendation and source interface, though I am not sure of the source interface command on Cisco.
show cable modem phy will show the Tx Power, DS Rx Power/SNR if Remote query is working.
Additional note on Cisco the community string for remote query cannot be the same as the community string the CMTS responds to. i.e if the CMTS is configured to respond to community private, you cannot use private for the remote-query community.
For CASA Systems.
! cable modem remote-query configuration
cable modem remote-query 120 "snmp community"
cable modem remote-query loopback 1
============
Configure a loopback interface.
(config)#interface loopback 1
ip address a.b.c.d 255.255.255.255
==============
In the CM Configuration File Add :
SnmpMibObject docsDevNmAccessStatus.1 Integer 4; /*OID: .1.3.6.1.2.1.69.1.2.1.7.2*/
SnmpMibObject docsDevNmAccessIp.1 IPAddress a.b.c.d; /*OID: .1.3.6.1.2.1.69.1.2.1.2.2*/
SnmpMibObject docsDevNmAccessIpMask.1 IPAddress 255.255.255.0; /*OID: .1.3.6.1.2.1.69.1.2.1.3.2*/
SnmpMibObject docsDevNmAccessCommunity.1 String "snmp community" ; /*OID: .1.3.6.1.2.1.69.1.2.1.4.2*/
SnmpMibObject docsDevNmAccessInterfaces.1 String "@" ; /*OID: .1.3.6.1.2.1.69.1.2.1.6.2*/
==============

Hi,
thanks for the reply.
I have configured:
! cable modem remote-query configuration
cable modem remote-query 30 remote
I also add to cm config file:
SnmpMibObject docsDevNmAccessStatus.7 Integer 4; /* createAndGo */
SnmpMibObject docsDevNmAccessIp.7 IPAddress 213.157.249.250 ;
SnmpMibObject docsDevNmAccessIpMask.7 IPAddress 255.255.255.255 ;
SnmpMibObject docsDevNmAccessCommunity.7 String "remote" ;
SnmpMibObject docsDevNmAccessControl.7 Integer 2; /* read */
SnmpMibObject docsDevNmAccessInterfaces.7 String "@" ;
But I didn't configure loopback interface...because I don't use loopback, but gige 0 interface.
SNMPWALK from remote snmp server works fine...but remote-query from CMTS: "show cable modem remote-query" don't.
What I am doing wrong?

I have configured remote-query and it shows: SN, US, DS parameters now.
MAC Address IP Address S/N US DS TX Time Micro(dB) Modem
Ratio Power Power Offset Reflection State
4023.4368.cca4 10.104.239.249 40.0 42.5 1.7 1 31 online
4023.4368.cd4c 10.104.235.251 -- -- -- -- -- online
4023.4368.d4bc 10.104.239.254 40.2 41.8 1.7 1836 33 online
But still don't show in "show cable modem verbose"
Configuration file name :n/a
sysDescr :n/a
Any idea how to implement that?
Regards, 0603
Loopback is not for your purpose to use.
It is for CMTS itself.
Configure a loopback interface with a /32 Mask. You will see the values you are looking for right away.
I would suggest to increase the remote-query TIME as well.

Endrit
Endrit thanks for a quick reply.
Do you also know how to implement "show cable modem verbose"
Configuration file name :n/a
sysDescr :n/a
I would like to see the sysDescr and config file name in "verbose".
Regards, 0603
I think both file Name and SysDescription Depends on the Software version.
For CASA C3K i think it's not possible. I maybe wrong on this.
Regards,
Endrit
It works on C3200.
If anybody else needs this...
Added in config file:
SnmpMibObject docsDevNmAccessIp.8 IPAddress 255.255.255.255 ;
SnmpMibObject docsDevNmAccessIpMask.8 IPAddress 255.255.255.0 ;
SnmpMibObject docsDevNmAccessCommunity.8 String "private" ;
SnmpMibObject docsDevNmAccessControl.8 Integer 2; /* read */
SnmpMibObject docsDevNmAccessInterfaces.8 HexString 0xff ;
SnmpMibObject docsDevNmAccessStatus.8 Integer 4; /* createAndGo */
On CMTS:
cable modem remote-query 30 private
P.S.
Zdenek thanks. :)
