Are you still monitoring your network routers, switches and ASA’s? Why not use the power of predictive analytics to safeguard your network health? indeni is the only network management tool built to predict issues lurking in your network before they become critical failures.
Dynamic Knowledge for Cisco devices:
- Guarantee router, switch and ASA configurations are done correctly (ie: matching routing tables)
- Optimize firewall performance (tracking CPU, number of connections, dropped packets on ports)
- Monitor device logs to prevent loss.
indeni is committed to continuously improve the High Availability performance of Cisco Routers, Switches and ASA’s. For mission critical systems, this means millions of dollars operation savings from outages and failures as well as highly reliable image and reputation, which are the two critical success factors for any business. For enterprise customers, this means continuous process for critical business communications and applications, which will dramatically increase an enterprise’s productivity as well as competitiveness.
Monitoring routers and switches in the era of predictive analysis can be made simple:
Someone has made a change on a switch or router and forgot to “wr”. A month later you have a power cycle and the network misbehaves. Wouldn’t you rather avoid that?
Data sources: comparing "sh run" and "sh start".
EIGRP configured correctly, but something isn’t working
Now that you’ve read how to configure EIGRP, which is supposedly a magic protocol, but something still isn’t working. Traffic is disappearing into a void, never to return. What could be the cause?
indeni predictive analysis examines the configurations and statistics of all the different routing protocols – EIGRP, BGP, RIP, etc. – to determine where there might be an issue. For example, did you know indeni will tell you if you have a route published via EIGRP for a network you don’t have access to?
Data sources: running configuration. Commands used: show ip route <etc.>
Keep track of STP
Do you know when you have STP topology changes? Do you get alerted for each one, or only when there is a suspicious amount occurring in a short period of time?
If you try to set this up in SolarWinds, you’ll see how difficult it is to get right. indeni includes STP tracking out of the box, so you’ll get only the interesting alerts with all the relevant data.
Commands used: show spanning-tree, show spanning-tree vlan.
Know if the next-hop router is down
Sometimes it can be difficult to identify who is impacted when a router or firewall goes down. It may require some specific configuration at times.
To deal with this concern, indeni crosses the routing table with the list of ARP entries. If a next-hop in the routing table shows up as an invalid or missing entry in the ARP table, indeni will alert.
Data sources: routing tables, ARP tables.
Is your OSPF tree rebuilding too frequently?
OSPF tree rebuild can be resource intensive. If it happens frequently it may mean you have a network issue but it surely means you’ll be having a performance issue.
indeni tracks the OSPF tree rebuilds and alerts if they occur too many times within a short timeframe.
Commands used: show ip ospf statistics
Hopefully, this hadn’t happened to you: a cluster member has a hardware failure. The secondary member comes up fine, but people are still telling you the mail server is not responding. After 4 hours of investigation, you find out the secondary member wasn’t configured for the mail VLAN.
indeni will identify when the VLANs configured on a trunk port are different between two HSRP cluster members.
Commands used: show standby, show int, show run, etc. Data sources: compare configurations of each port.
Monitor interfaces for drops, errors, collisions, etc.
Drops usually occur when the traffic load is more than the interface can handle.
Errors usually occur when the duplex settings are wrong.
Collisions usually occur when you have a setup from hell or simply outdated.
Whatever it is, you need someone to keep an eye and tell you when there are more drops, errors and collisions than there should be. It would be great if that someone would also tell you what interface it’s on, the speed+duplex settings for that interface, the IP addresses, MAC address, etc.
Commands used: show int.
Is something core-dumping on you?
Sometimes it’s difficult to notice when one of the functions on a router or switch fails. That’s because the failure results in a core dump and an immediate restart of the function. From the outside, it looks like a temporary issue, but a core dump is never temporary. It’s something that needs to be investigated.
indeni will keep a watchful eye and tell you when a core dump occurred, so you can stay on top of things.
Data sources: core dump directories.
Test your devices for known vulnerabilities
Is the IOS version you are running vulnerable? indeni will let you know if it is.
indeni compares the current running version of software on each analyzed device against a list of software versions and known vulnerabilities. If we find a match, you get an alert.
Commands used: show version Data sources: internal database of known vulnerabilities.
“We realized there was an issue with the Polycom but couldn’t figure out what was happening. It would exhibit very sporadic behavior. In retrospect, after discovering the cause (with indeni for Cisco), it makes perfect sense! I think this is a great example of why every organization needs automation.” — Ryan Leonard, CIO, FXCM (NYSE:FXCM).
