Cisco WAN :: 1841 - SNMP OID For Interface Utilization
Jan 13, 2013
I have a cisco 1841, Im trying to write an app which will get the Interface Utilization on my 2 atm interfaces and fast eth 0/0 interface.
I’ve been reading up and have got as far as downloading the codeplex snmp library project. I’m using the snmpget app to get details off my 1841 successfully, but I now need to know the OID for interface utilization and how to define which interface to get.
I have a problem with SNMP. I using Cisco 3845 in distribution layer. >600 subinterfaces. When my managment system send response - the cpu Utilization on cisco3845 near 100%. I want to prohibited my Cisco answer on response about interface status.
I matched the traffic statistics on one of my Cisco ASA site-site tunnels with the OID:184.108.40.206.220.127.116.11.18.104.22.168.22.214.171.12442 (cipSecTunHistInOctets). I was real proud of myself for a few days until I checked the history and found the OID wasnt working.After some troubleshooting I found that the last four digits (4142 in this case) change whenever the tunnel drops and re-establishes itself. Any way to collect tunnel utilization history on an ASA with SNMP? Is there a different OID I can use thats based on the endpoint IP?
When the client on a Branch Office LAN realizes calls to skype, there is a sharp loading of CPU on Branch router Cisco1841 (all Inet traffic goes through DMVPN-Tunnel Interface to proxy on Central Office).
LMS is not reporting on all of my interfaces, utilization in particular. As an example, I have 1 location that is connected via DMVPN tunnels, when I run a utilization report, it only comes back with information for 1 interface, a random interface, port FA 1/7 on the switch module. If it was all of the switchports it might make more sense.
In DFM device detail the interfaces are being managed.
In the Link Utilization Poller, only 1 interface is listed (FA 1/7).
I have one question regarding switch sg300-10. How can i check current interface utilization in bits/second? If I use show int counters I can only see number of unicast, broadcast and multicast packets....plus total packets. But there is no info regarding input and output rate for particular interface (like in original IOS when using show interface command).
I have a problem with System-defined Link Port Interface Utilization Poller. When I generate Interface Utilization Report, this one just displays few Interfaces (see the figure in my attachment). I checked the default poller for interface utilization and recognize that it just associate with few Interface (same as in Interface Utilization Report) instead all. I need to display the utilization of all interfaces in my report
Is Link Port Interface Utilization wrong or Is it necessary to creat user-defined poller that associate with all interfaces of devices?
I'm using a stack of four SGE2000P switches for a PoE video camera system. I've got the cameras in a VLAN and everything's working fine.
I'm wondering, though, is there a way to find out what data rate the stack interfaces are working at (since it's going over cable infrastructure we put in ourselves), and also what percentage of that bandwidth is being used? I don't see anyway to get to those interfaces from the main page, and I wasn't able to find a way to do any sort of percentage thing even on a regular interface.
I am getting these unwanted entries on my syslog server.03/10/2012 12:57:48 172.21.113.20 Error 23898: Interface FastEthernet0/1, changed state to downI tried to stop them with no snmp trap link-status but it hasn;t worked.[CODE]
i have a Problem with SNMP on the ASA Outside Interface. I want to monitor the Interface via SNMP (linkup, link down). I have a Active/Passive Cluster running on 8.4.2 and configured SNMP (v1) for Test on the Outside Interface. It's not that hard but when i try to test my Configuration with (peerless) SNMP Tester the Interface doesn't respond. Did i forget to configure something? Searched the forum but didn't find anything useful.
The other day 3rd party supplier ran some stats on our Gigabit link between 2 Cisco catalyst 3750Gs.now the graphs produced showed only a Maximum output of about 100Mbps ( 5 minute intervals) yet when I do a show interface it shows a lot more always 150Mbps and more. So I did my own Perl script doing an "sh interface" every minute and then graphed it, and the results were a lot different to the MRTG results.Questions: I know MRTG uses SNMP to get the traffic is there a bug in the SNMP, what OID does it use?does the "sh interface" give the correct results?
i noticed the "output drops" increasing in interface gi 1/0/1 in my switch 2960-S although the utilization of my interface is between 20% and 50 %
SW__A#sh interfaces gigabitEthernet 1/0/1 GigabitEthernet1/0/1 is up, line protocol is up (connected) MTU 1500 bytes, BW 1000000 Kbit, DLY 10 usec, reliability 255/255, txload 93/255, rxload 3/255 Encapsulation ARPA, loopback not set Keepalive set (10 sec)
MIB OID and the values.also i want to know the values og output packet and output packet drops MIB OID values of POS interface on GSR router (12000).because i am getting many output packet drops on these pos interface.how do i get these values from the router.
I am attempting to monitor bandwidth utilization of the WAN port for the RV180 via SNMP and I am getting strange results. If a 256MB file is transferred from a remote server (without compression), the ifInOctets counter doesn't increment by anything resembling 256MB:
I'm reasonably certain that the .5 interface is the WAN port based on the value of ipAdEntIfIndex.X.X.X.X, but even if that were not the case, none of the other interfaces increment by a value close to the amount of data transfered. SNMP monitoring of a WAP121 on the same subnet returns expected results. I can only assume that SNMP on the RV180 is completely broken.
The router has the latest firmware available (126.96.36.199). There is only one network connection and the RV180 is the default gateway for all internal hosts.
I'm trying to add some 2800 series routers to our monitoring environment, but I can't get them discovered.
On the Mgmt Server I need to go through a "discovery" process to add the 2800 to the system. For this I target the internal interface ( i) but the discovery fails. I'm assuming the packets are getting dropped on the outside interface (e). I know SNMP is set up correctly and works as I had PRTG installed on a local box (p) for testing purposes.
The intention is to do the data gathering via a proxy agent (p), so enableing SNMP on the outside interface is not going to do me any good.What do I need to do to let those discovery packets pass through? At least temporarily?
Any chance of one or preferably both of these before I flash the router to a more competent firmware?Rather ridiculous that there's no interface counters and no SNMP server. I prefer keeping stock firmware where possible but I need this functionality, it really isn't a big ask.That said I have an E4200 v1, which already looks like abandonware given it's been 6 months since the last firmware update - not amused and no intention of swapping a high performance router for one that sacrifices performance for better NAS functionality.
I am trying to figure out how to use a Cisco 1841 IOS router to take traffic from one interface and source NAT it out towards the Internet on one interface and at the same time NOT perform NAT when sending the traffic towards a different routed interface.
Here the RemoteSite has connectivity back to the MainCampus, but there is no need to NAT traffic from the one site to the other. They share the same umbrella of address space. However, the RemoteSite needs to have its Internet-bound traffic NAT'ed out to the Public Internet via a third interface. I know that I could just NAT everything out from the Remote Site and map the traffic back onto the same address space for intra-campus communication, but I'd rather avoid that and just NAT where I need to NAT it to the Internet.
I do have a caveat here: in the event that either the MainCampus or the Public Internet interfaces go down, I would like to failover traffic from the downed link to other good link. For example, I want to NAT all traffic (including "intra-campus" traffic) out via the Public Internet if the direct link to the MainCampus is down. For the other example, if the Public Internet direct link is down, I would just send out all traffic without NAT towards the MainCampus.
I am trying to roll out a new internet router. The problem I am faced with is the LEC only supports VLAN 1227 and greater, specifically they are assigning me VLAN 2528. I am able to create the sub-interface and setup dot1q encapsulation for VLAN 2528, but the vlan database does not have the ability to add VLAN 2528 to it so I am unable to get layer 2 up and going, thus preventing me from getting the implementation done.
I use an 1841 router as an internet facing firewall with a 10MB MetroE connection. Lately users started reporting slow internet download speeds and web pages timing out. Bandwidth reports do not show the link as being saturated so I looked at the interfaces on the 1841. The interface connected to the provider shows OK as far as errors but the LAN side of the router shows steadily increasing input errors. It doesn't show any other errors, no CRC, frame, runts, giants or overruns, just generic input errors. What type of errors are those? Nothing is being logged on the console.
I moved the connection to another switch ports and the errors continue. I switched it down to 10MB and also changed the switch and the errors slow down but don't stop. Interestingly, the switch side never shows any errors. What can I do here? I guess it can be a bad interface but that is such a rare thing that I am hesitant to replace the router.
I have a question about SNMP OIDs for the command "show counters interface intx/y delta" on Catalyst6500. The customer wants to create graphs for the following values:Overruns, qos0Outlost, InErrors, OutErrors, InDiscards, OutDiscards etc..Is possible to get these values using SNMP?
I have an 1841 between my firewall and the ISP. Three interfaces - multilink to ISP, FA to my firewall, and FA to my inside network. I use the inside interface for configs aand snmp access, etc. Only my ISP-assigned fixed address block will get routed to the multilink by the ISP but I am nervous about the inside interface sitting on my LAN. I know I can remove it, but if I keep it there, how can I set up an ACL so that all traffic from the multilink interface is denied to the inside interface? I suppose another way to think about it that the inbound iface can only accept traffic from its own outside, not from the router.I think this is fairly simple but I don't want to knock down the traffic if I get it wrong.
We have an ADSL2+ line from a WIC in a 1841, everything has been fine for the last few years and then the last few months the connection going down. When checking the interfaces the ATM0/0/0 is up up and the same for the dialer interface we are using, they are both up/up, but this still needs a reload of the router to be functional again, shutting the interfaces does not bring the connection back up.
I am not an expert on ADSL lines, I have never really had a problem with anything previously. The router was running Netflow to a network monitor wondering if this or logging was causing an issue with entries in the buffer??
Here is an output of show dsl int, would change the firmware, it has been fine all this time before though we are running IOS 12.4(24)T1 advseck9-m, as far as I can seen from our ISP the config for ADSL is all correct. [Code]
We want to terminate new 10M link via Ethernet interface on Cisco 1841 router. We have free Gig port on the router. We also have HWIC-FE module inserted in the router. However, our implementation team said that Cisco 1841 doesn't support 10M link. It is not designed to cater to such high Bandwidth.
