Cisco :: How To Find Useful MIBs For Cat 6500 / ASA5540 / Cat 3750-E Devices
Jan 10, 2013
i am setting up a new Monitoring System (CA Netvoyant). It has some default Cisco monitoring capabilities ( I believe these are soem standard MIBs). I am wondering how can I add more useful Cisco MIBs for the devices I have in my network. There are thousands of MIBs and it looks like it is not easy at all to find the useful ones.For example the MIBs that can give you Emergency and up to warning level information, cpu, memory, interface errors, module failures (in case of Cat 6500), FWSM, BGP, VPN tunnel status notifications. Is there a list of useful MIBs for each device type, like Cat 6500, ASA5540, Cat 3750-E etc depending on IOS Image? setting up the SNMP monitoring system?

I would like to monitor the status of ether channel and trunk configurations in 6500 Catalyst switches running both CATOS and IOS. I would like to understand the specific mibs /OIDS that should be monitored for ether channels and trunks. I am trying to get a better handle on tracking the ether channels and trunk dynamically and then understanding when the ports are having issues (up/down and errors). I need to understand how to differentiate these type of ports from regular access ports.

i have two CAT3750 need to place in L3, and it supposed that used as L3 switches by SVI for L2 routing, and I want to these two configured as redundancy by HSRP. but now I can only have one ASA5540 to connects these of L3 switches.
so, here is my questions:
1. does ASA5540 support multi vlan?
2. does it support spanning tree protocol?
3. if I've choiced to use trunking between two L3 switches, does it can pass through HSRP hello msg?
4. achive network redundancy

I have a doubt regarding MIBs. I dowloads the MIBs for Cisco 4503 for a specific IOS. But the folder is divided by v1 and v2.
What does it mean v1 and v2? The version of SNMP?
So if I enable just SNMP Trap (''snmp-server enable traps.....'') I should use MIBs v1 but if I enable also the number of Retries and Timeout ( ''snmp-server inform retries...'' and ''snmp-server inform timeout...'') I sould use MIBs v2.

I have a network that has a pair of 6500 switches on either end, running HSRP. In between each 6500 are two to three ruggedcom switches. They are connected to each other and the 6500's by trunk ports in a straight line. The 6500's see each other as CDP neighbors, and the 6500's can see the rugged- com as LLDP neighbors (ruggedcom only supports LLDP).
The issue is that randomly devices on the ruggedcoms will drop offline and then come back. The problem is that the devices that drop offline are all in the same VLAN, so it appears like a virus - i.e. one device drops off, then multiple. Eventually the HSRP starts flapping between the two 6500s and this causes havoc on the network.I'm almost to the point of taking a laptop and plugging it into one of the ruggedcom's to see traffic, but the issue is that the ruggedcoms are outside in cabinets that laptops shouldnt be exposed to.

My DFM is showing 40 devices in the "Questioned" State. Lots of them are 3750 switches and 2801 routers. It has "Known" a few of the 3750s and 2800s, but most of them are Questioned. How do I go about troubleshooting this? It's
DFM 3.2.0, part of LMS 3.2;
I tried to reinitalize the DFM database, but that caused all sorts of other issues like my ANIServer not running anymore etc. I have a ticket open with TAC for that issue though.

We have a need to access an VLAN at the main office( ie Core Switch 6500,switch 3750) from a remote site(Cisco3845 router, Switch3750) connecting by a SP through fibre link.
what is the easiest and quick way to do it and the user from the remote site just want to have access to that VLAN for a couple of days only.

We have a pair of Cisco 6513 switches, to which a selection of Wintel/Linux/UNIX servers are attached, but we have some connections that we can't identify and the data centre is a remote lights-out operation operated by a 3rd party in another country. determining which server NIC ports connect through (via patch panels) to which ports on the Cisco switches.In particular, I have a UNIX (HP-UX) server that has 4 dual port NICs (ie. 8 LAN ports), of which only one is assigned an IP address, but I can see that the other ports have connectivity at level 2 (HP-UX has a "linkloop" command that is analogous to an IP "ping" but takes a MAC address, and I get a response from each when I check from another server). This means that I know that there is a physical, electrical, and level 2 connection.The one server port with the active IP address set up shows in the switches address table ("sh mac-address-table") and it gives the port it is attached to. But the remaining 7 ports do not have IP addresses assigned and so are not listed in the table.

I am having a major issue trying to connect my Windows 7 HP Netbook to my Xbox 360 over either Twonky/Serviio or Windows Media Centre. The Xbox just isn't picking up my computer, my homegroup recognises the Xbox and it is 'Allowed' to share media, but when I test my PC connection within the Xbox dashboard, it fails to connect to PC. My network is wireless.The strange thing is I have TwonkyServer Mobile running on my Android phone and that was found by my Xbox immediately with no need to change settings or search for devices. It streams media just fine from my phone. This leaves me thinking that it is an issue with my PC as opposed to my router, I have double checked my router settings (Sagem 2304), UPnP is showing as enabled, I've reset and unchecked/rechecked the UPnP but still not working.
My TwonkyMobileServer is also unable to find my PC server although I have been able to find my MobileServer in Windows Media Player and stream media from my phone.Windows Firewall has been disabled, I've also Uninstalled my antivirus software, Avast and AVG, although AVG doesn't seem to want to disappear that easily and is still lurking in my System Tray telling me i've 'Lost protection'...Norton Internet Security is also lurking around which is odd, I can not recall installing it! It doesn't seem to be a fully installed version and doesn't seem to want to be uninstalled. Could these AV software and supposed Internet Security software be holding me back?This leaves me thinking that my PC is holding back my Network. Is there any thing I haven't thought of? Would it be the Anti-virus leftovers ruining my streaming dreams??

I am planning to migrate the core switch from cisco 3750 to Cisco catalysts 6513 switch. What could be the best approach to minimize the downtime or avoid disrupting the production. I have couple of thoughts, one method is to build the core and then replace the existing core, another option is to build the new switch as the second VTP server and once it recieves all the VTP information then disconnect the old server.

I got 10 Catalysts 3750 (all of them identical) and I got the IOS Update. Anyway I only have service contract for 4 of them.
Am I allowed to update all of them? Or only the four devices which have the service contract?

When I do an Inventory Collection, the job doesn´t work with some devices and I have to restart the server. The job doesn´t fail but the log ICServer.log doesn´t got any information and it works for hours and hours and when it finally stops I can see that devices are not attempted.
I have done some succesfull Inventory Collections with Cisco 3750 switches and 805 routes. I have tried witch Cisco 2811 routers and 2950 and 2960 switches but it doesn´t work.
I have tried to update my LMS4.0.1 but it doesn´t find any actualization. However, in the Cisco download page there are some patches.

I am trying to track down the SNMP MIBs for the Linksys by Cisco SRW2048. Please note that this is the model before the complete CISCO rebrand of the product. I have SNMP walked, browsed etc etc and I just can't pull CPU and RAM usage. Any working view of those two stats? I'm using OpManager by ManageEngine as my NPM platform.

I have 2 6504's running HSRP as my core. They are each etherchannel'd to my Datacenter switch (3750 Stack) -- see image below.The problem i a having is with the etherchannel status:
Core1 PO11 status w (waiting)
Core2 PO11 status P(bundled)
DC11 PO48 status P -- but only to Core2 - the interfaces to Core1 are suspended. (See attached configuration documents) None of the devices have any information in the logs. I run this same configuration in my central location, but we are running Nexus 7000's. With the 6500's, do I need to split the port channels on the 3750 to allow them to negotiate the etherchannel? If I split the portchannels, are there any concerns? Should I expect to see the etherchannel status as P (Bundled) or H (Hot-Standby)?

I have recently purchased an SG-300-52 Managed Switch. (This is the first managed switch I have used, so I am trying to figure out what I can do with it and how it works.)
I would like to know how to find out the IP address of each computer connected to each port of the switch. Is this possible and if so how can I do this from the browser interface?

I have a requirement to connect two 3750 switch with 10G speed between two sites with 150km distance. We will lay-out our own fiber (48 core) between two sites. I just want to consult the following:
1. Could i use two core switch 6500 with single mode fiber as a transport equipment?
2. Or i need to use SDH equipment because of the distance concern? If so do i need a repeater?Could i use Cisco Metro Core ONS, which one?
3. Any other option to achieve this requirement?

I am having some question around Prime Infrastructure..Does a general document exists regarding the licensing count of monitored devices ? Indeed I am wondering about the specific points. Is it true that :
- A 3750 stack unit count as one (for example a 4 units stack consumes 4 license) ?
- A WLC (except 5500) does not consume a license but only the Lightweight APs.
- An autonomous AP does not consumes a Lifecycle licence ?

I've had been successfully using a WRT400N to extend my wireless network as follows:
The WRT400N connected to my network via an Ethernet port in my kitchen. The cable ran down to a corner of my basement connecting to Verizon router that brings in our Internet, TV etc.
The Verizon router's poor location was a problem, and placing the WRT400N in the kitchen worked perfectly, providing excellent network access and Internet to wireless devices throughout my home. It worked fine for over a year.
Recently, we had a power outage which reset the WRT400N to factory settings. and I am having trouble getting it to work again. I set it up in the first place, but am now having difficulties. Clearly, I am no guru!
I tried to get it going again by: 1) plugging the WRT400N into a PC and giving it a new IP address that would not conflict with the Verizon router (both default to 192.168.1.1) 2) turning off DHCP, 3) renaming the router, 4) changing the router password, 5) setting up a WPA2 security key.
I then plugged the WRT400N back into the kitchen Ethernet port, but something is wrong. Wireless devices cannot find the WRT400N.
The good news is that I can "see" the WRT400N through any PC on the network via a browser and access setup, but the bad news is that devices cannot see or connect to the wireless signal.
When I go to "Status" it shows the IP address, subnet address and default gateway all at 0.0.0.0. On the SETUP page, it has the correct router address (192.168.1.9), and a subnet mask of 255.255.255.0. Not sure if it is supposed to be this way...

Is there a command to find your optical tx/rx power (dBm) on a 3845? On a 3750 you can do a show int transceiver; looking for a comparable command for ISRs.

I meet a strange question about IPSec VPN between '' C3945 A---ASA5540 A----------Internet----------ASA5540 B---C3945 B "
I set ipsec vpn between ASA5540,and set Tunnel between C3945.the C3945 Configuration as follow:
C3945 A C3945 B
interface Tunnel10 interface Tunnel10
ip address 172.18.1.225 255.255.255.252 ip address 172.18.1.226 255.255.255.252
tunnel source 172.17.0.1 tunnel source 172.17.1.121
tunnel destination 172.17.1.121 tunnel destination 172.17.0.1
the strange issue is like that:
On C3945A : I can ping 172.17.1.121 with the source address 172.17.0.1,but can't ping 172.18.1.226
On C3945B : I can ping 172.17.0.1 with the source address 172.17.1.121,but can't ping 172.18.1.225
