SNMP Monitoring Etherchannel LACP Bandwidth

Can someone please describe how I would work out how to monitor the bandwidth usage of an etherchanel on WS-C3750V2-24PS-S
What is the process I use to find the MIB / OID I need. It seems like a wild goose chase.
Can someone please lay out the process , where I search on CISCOs website, commands I use etc.
Thanks,
Dan

Ruben,
The MIBs for the concentrator is here:
http://www.cisco.com/public/sw-center/netmgmt/cmtk/mibs.shtml . The link takes you to the page where you can get to all the Cisco MIBs. I found the OIDs that I wanted to monitor which were the following:
.1.3.6.1.4.1.3076.2.1.2.17.1.6.0 - Peak VPN Users
.1.3.6.1.4.1.3076.2.1.2.17.1.9.0 - Active Sessions
What you probably want to see as well is active Site-To-Site, you can use this OID:
.1.3.6.1.4.1.3076.2.1.2.17.1.7.0 - Active L2L Sessions
In order to find the OIDs, use the GetIF utility and download the MIB package they have. It is a large zip file and contains all these MIBs too. Use the MIB walker and go down the tree to .iso.org.dod.internet.private.enterprises.altigaRoot.altigaGeneric.altigaMib

SNMP Monitoring shows bandwidth x2

I have tried a couple SNMP monitoring applications on both my Mac and Windows machines and both are showing my WAN usage as double what it should be. I have a 15Mbps connection to the Internet and when I do a speedtest it shows as 30Mbps on the mgi1 interface. I have noticed this for awhile (pretty sure several firmware versions) but thought I would reach out to the community finally. I am running 7.6.4 on my TC Gen4.

Hi deepu vc,
For bandwidth monitoring you should use the SNMP Traffic Sensor or a NetFlow Sensor. PRTG offers various versions:
NetFlow 5
NetFlow 9
IPFIX
I linked the corresponding pages of the PRTG manual. Within the next few weeks there will also be a new Trap Receiver Sensor.
I hope this helps...
Kind regards,

SNMP per-ipsec tunnel bandwidth monitoring

Whish oid can be used for monitoring bandwidth (bps, kbps...) per ipsec tunnel, assuming there is now logical tunel interface configured?
ios supports CISCO-IPSEC-FLOW-MONITOR-MIB, but cannot find oid in ftp://ftp.cisco.com/pub/mibs/oid/CISCO-IPSEC-FLOW-MONITOR-MIB.oid.
Tnx!

Hi Spr,
Check out VPNTTG (VPN Tunnel Traffic Grapher) is a software for SNMP monitoring and measuring the traffic load for IPsec (Site-to-Site, Remote Access) and SSL (With Client, Clientless) VPN tunnels on a Cisco ASA. It allows the user to see traffic load on a VPN tunnel over time in graphical form.
Advantage of VPNTTG over other SNMP based monitoring software's is following: Other (commonly used) software's are working with static OID numbers, i.e. whenever tunnel disconnects and reconnects, it gets assigned a new OID number. This means that the historical data, gathered on the connection, is lost each time. However, VPNTTG works with VPN peer's IP address and it stores for each VPN tunnel historical monitoring data into the Database.

Prime\SNMP Monitoring of dynamic interfaces

Hi - Is anyone aware of a method of monitoring the bandwidth utilisation on a dynamic interface on a WLC?
I'd like to monitor the traffic on each dynamic interface to generate usage stats on centrally switched guest and employee SSID's.
Thanks

You have to get that stats from switch where you defined those SVI. WLC dynamic interface not terminate any L3 traffic & switch SVI is the place to go.
If you have netflow monitoring or simple snmp monitoring tool, you can get that stats from the switch.

Monitoring IPSec Tunnel Bandwidth Utilization

We have a Cisco ASA 5520 supporting multiple VPNs - both remote-access and Lan-to-Lan. We would like to monitor the bandwidth utilization of the IPSec Lan-to-Lan tunnels. How can we do that?

SNMP monitoring of Oracle 10g?

Hi there,
I'm curious about using SNMP technology to monitor Oracle 10g databases.
I've done some light reading on the subject and I'm now at the stage
where I have a few questions.
-What exactly do I need to configure in my Oracle 10g environment?
-Is Enterprise Manager the best and/or only UI available for me
to carry out configuration chores?
-I see no SNMP specific documentation for 10g; why is that?
-I do see a good document for 9i:
Oracle SNMP Support Reference Guide Release 9.2.0 Part Number A96672-01
http://download-west.oracle.com/docs/cd/B10501_01/em.920/a96672/toc.htm
Is the above document suitable for configuring SNMP monitoring of Oracle
in a 10g environment?
-moi

I'm able to set up traps via the EM website following these instructions:
http://download-west.oracle.com/docs/cd/B19306_01/em.102/b40002/notification.htm
However, what I'm really looking for is the ability to do snmp gets. I need functionality similar to how the old school DBSNMP under OMS used to work. These commands seem to be totally missing. I found the following documentation:
http://download-east.oracle.com/docs/cd/B19306_01/em.102/b16244/chap2.htm#sthref74
Which indicates there should be an snmp subfolder under $ORACLE_HOME/sysman, but that folder does not exist in my installation. I installed Oracle EE. Is there another package I need to install in order to make the subagent run like a normal snmp agent?
So far if I do a:
emctl start dbconsole
that starts up the EM Website and I can use that no probelm. If I...
emctl start agent -- I get:
Starting agent ... started.
issuing a 'emctl staus agent' gives me a normal status message. Things start to get strange when I try to start the subagent, which to my understanding is what I need running in order to to talk to net-snmp, which is the master agent running on this host. Here's what happens:
[zaro@cheetah bin]$ ./emctl start subagent
Oracle Enterprise Manager 10g Database Control Release 10.2.0.1.0
Copyright (c) 1996, 2005 Oracle Corporation. All rights reserved.
Starting sub agent .....started
[zaro@cheetah bin]$ ./emctl status subagent
Oracle Enterprise Manager 10g Database Control Release 10.2.0.1.0
Copyright (c) 1996, 2005 Oracle Corporation. All rights reserved.
Sub agent is not running..
I guess my question is how do I get to have the ability I used to have back in 8i to start up dbsnmp and then have my SNMP monitoring app "discover" the agent and use its instrumentation to get data?

Is there anyway to monitor network traffic on the newer Time Capsules, similar to the SNMP monitoring previously?

Is there anyway to monitor network traffic on the newer Time Capsules, similar to the SNMP monitoring previously?

Can I use a real router and still have the Time Capsule for backups etc?
Yes, that is what Bridge Mode is for. Just connect the Time Capsule to a LAN <--> Ethernet port on your "main" router.

Recommended product for syslogging and snmp monitoring

Hi,
    We currently use KIWI syslog but can anyone recommend a better product for syslogs from Firewalls, Routers and Switches. Our current product creates a seperate text file per day per device. Ideally I would like all these to be combined (or combinable for display purposes) into one log that shows to update realtime and have the ability to filterout "background noise" - stuff we know is acceptable, as well as being able to run simple or quick searches and reports. Ideally for asbout 200+ devices.
     Am I too hopeful or is there a product out there that can do this (that also will not break my companies bank account).
     Also, recommended products for SNMP monitoring if better than we currently use would be useful - currently using Orion and SNMPc.
Regards
Adrian

Adrian,
We use syslog-ng for RHEL. It can do what you need as far as writing to files and filtering out background noise, but it is not a search/reporting tool. If KIWI does the latter, I imagine you could tell it to read from the file that syslog-ng creates.
It is open source for writing files through version 3.1.4. Later versions require licensing to write to files or if you are using a Windows OS.
http://www.balabit.com/downloads/files/syslog-ng/open-source-edition/3.1.4
Here are some other options:
Rsyslog: http://www.rsyslog.com/
Splunk: http://www.splunk.com/
Snare: http://www.intersectalliance.com/projects/index.html
Hope this helps.

SNMP Monitor PIX throught VPN tunnel

I have two Cisco PIX 515e firewalls configured in fail-over. The primary PIX has private address 192.168.1.5 and the secondary PIX (standby) has a private address 192.168.1.6. The PIX firewalls are running IOS 6.3.3. I'm connecting to the PIX firewalls through a VPN tunnel (PIXes terminate VPN tunnel) and my monitoring system uses SNMP to monitor devices behind the PIX firewalls and the primary PIX private IP address. I would also like to monitor the standby IP address 192.168.1.6 from the tunnel and have been unsuccessful thus far. I can do this from behind the PIX, but not through the tunnel (only the primary PIX).
Is there a way I can SNMP monitor (and PING) the IP address of the standby PIX through the VPN tunnel?
Please send email to [email protected]
Thank you,
frank

Paul,
Thank you for your email. Yes, we currently use this command to monitor the active private IP of the active PIX firewall through the VPN tunnel. What I would like to be able to monitor is the private IP address of the standby PIX firewall (has a different IP address while in standby mode) would like to make sure that it too is up and running (I can do this today for other PIX firewalls from the inside, but not through the tunnel.
Best regards,
Frank Pikelner
Hi Frank,
Dont think you are going to get that to work due to the routing issues. Sending syslog messages to the snmp server is the only way Ive done it in the past. Have you given this a try?

EtherChannel (LACP) Configuration - Catalyst 3750x

Greetings,
I have a couple questions for the group.
Q1) Should the port configuration options of each individual line of the etherchannel bundle also be reliazed on the logical port-channel interface? In the below example, should "spanning-tree portfast" and "spanning-tree bpduguard enable" be coded on the port-channel interface?
Q2) Are there any best practices, general rules, or nuances you can share regarding the configuration of etherchannels as it pertains to the above question? What about etherchannel trunks?
Thank You
========================
interface Port-channel3
description EtherChannel (LACP, 2-port) for Server1
switchport access vlan 999
switchport mode access
interface GigabitEthernet3/0/12
description Server1 NIC1
switchport access vlan 999
switchport mode access
spanning-tree portfast
spanning-tree bpduguard enable
channel-group 3 mode active
interface GigabitEthernet4/0/12
description Server1 NIC2
switchport access vlan 999
switchport mode access
spanning-tree portfast
spanning-tree bpduguard enable
channel-group 3 mode active
========================

Thank you Leo for the reply and link.
Reading through the documentation you linked, I discovered this:
"NOTE After you configure an EtherChannel, configuration changes applied to the port-channel interface apply to all the physical ports assigned to the port-channel interface, and configuration changes applied to the physical port affect only the port where you apply the configuration."
This statement isnt quite clear to me. Does this mean that line-item configurations to the EtherChannel are propagated down to the individual ports? But line-item configuration changes made to indiviual ports will not propagate up the the EtherChannel?
So with the example I gave above, does Port-channel3 need to have explicit line-item configurations for "spanning-tree portfast" and "spanning-tree bpduguard enable"; and should it look like the following?
interface Port-channel3
description EtherChannel (LACP, 2-port) for Server1
switchport access vlan 999
switchport mode access
spanning-tree portfast
spanning-tree bpduguard enable

Monitor the traffic/bandwidth of local computers ?

Hi everyone,
What is the software/script to monitor the traffic/bandwidth of the local users ?
I'm currently has Xserve as like a DHCP/gateway, and there are about 20 computers connects through Xserve. I'd like to monitor the local computers to see their bandwidth but not sure what script/software need to be installed on Xserve. All my local computers have ip 10.10.x.x.
I installed darkstat but it doesn't show me the specific ip address that taking how much bandwidth (like download/upload speed..).
Thanks

Take a look at Intermapper <http://dartware.com/>, Lithium <http://lithiumcorp.com/> and Zenoss <http://www.zenoss.com/>. They should be able to do what you want. Hope that helps.

SCOM 2012 SP1 - Setup SNMP monitoring = ping OK, no response SNMP.

Hello,
I've tried the snmp monitoring in lab domain, everthing work. Now I work in the production environment, but I can't make work the snmp. I've tried only snmp, but the same error occure. The Ping is ok, all my firewalls rules allows snmp and ping over
the domain.
But when I launche the discovery, I've got an error after "No Response SNMP". I've analized the network with wireshark, I see the snmp get send to scom to the network device, but the netowrk device, reply " Destionation unreachable (Port unreachable)".
I've check with "netstat -ano -p udp" but I don't see the port 162, the 161 is open and snmp.exe service use it. But 162 is not open and Healthservice.exe doesn't use it.
I tried to reboot the server, but nothing change. And I check all my configuration, and it's the same in my lab domain and te production.
Anybody have the same issue? Or a workaround?
Thank you in advance.
KimBaxZ

Hello Roger,
1. Windows Firewall
a. SNMP service authorized
b. SNMP trap not authorized
c. PING.exe authorized
d. HealthService.exe authorized
2. SNMP service configuration
a. Security => Community name + Right OK
b. Security => Accept SNMP packets from any host
3. SNMP trap service disabled
4. The network device (cisco switch is already configured and the snmp work well)
a. It's possible to execute a snmp walk on the switch, and we get all the data (we use a différents
computer to do this, like a linux server on the same network)
5. We use snmp v2 on the switch, and during the discovery scom, send v2c snmp get to the switch with the good community name.
6. I tried to forge a snmp v2 packet and send them to the scom server, wireshark see the packet
During the discovery the switch get the snmp request, but he can't reply, the snmp trap port (162) on the scom server is not open. And I don't know why.

Nagios SNMP Monitoring for NSS devices ?

Has anyone managed to utilise the inbuilt SNMP functions of the NSS with nagios efficiently ?
if so, what plugins are you using and how have you got them configured ?
Steve

There are some threads in this forum regarding this already. It is not as easy as monitoring a switch or router. the controllers combine the AP mac with the oid for unique lines. You can glean some snmp info off the controllers by using some of the generic OIDs and controller specific OIDs, but you will need an snmp monitoring program that you can load the WLC MIBs into and then tailor your monitoring of the controller based on that. I use Cacti, which is really awesome, but I would need to grab the complete OID off each controller based on the APs on it, which is fine as long as the AP is on that particular controller and not another one. snmpwalk is your friend in this case.

SNMP Monitoring behind SCOM Gateway Server

Hi All
Is it possible to monitor Network devices / SNMP that sit behind a SCOM Gateway server? If so, how do these get discovered?
I have a need to monitor devices like HP printers, WAP, JetDirect cards, EPOS equipment etc. on a site that doesn't have SCOM on-premise.
Are there any limitations to this?
Thanks

Hi,
Yes, it is possible. when you create discovery, you may specify that it should run from gateway server.
On the device you want to monitor, set your SNMP public community string to point to the IP address of the SCOM Gateway server. In the SCOM Administration console, choose Network Devices in the Discovery Managment Wizard choose network device and click next.
In the next screen enter the IP address of the network device you want to monitor and under the mangment server drop down choose the gateway server who’s IP you entered in the SNMP string earlier.
Here is a similar thread for you reference:

In addition, you may check is there any management pack for your devices and import them into your management group.

Snmp monitoring for wlc 4404

Hi,
we use a snmp monitoring software called Nagios in our LAN. Now we have two WLC 4404. Is it possible to monitor values via snmp? Is someone else doing it so?
Witch values can be monitored and for what values is it wise or practicable to monitor it?
Regards
Christian
