I use NTA version 3.6 and find it very useful in keeping track of customer QoS policies. We track the shaping policy on the WAN interface which can be pulled from the router via SNMP then use the flow analysis to pull which DSCP classes are in the exported traffic (and indeed imported). In many respects, depending the…

Hi There, When we send customers HA kit (running HSRP for example) we tend to replicate the DHCP scope to both routers. One of the issues in splitting it up means that they'll need a big enough scope to cover the machines twices over which means a large waste in address space. The Cisco's can be configured in such a way…

 Hi Guys, Slightly unrelated/off topic but is it possible to reprocess old data with new rule functions as a batch job to get it to display correctly? If this isn't done automatically by Orion could it be done manually with a database copy and merge? (assuming the flag the NTA uses is applied to the flow tables in the…

It may be possible to set this up in other ways depending what network devices you have in your architecture? If you know the address space of the country in question (which you can get from IANA and the like) it should be relatively straight forward in Cisco's to create say, a policy map to DSCP flag this traffic (and you…

ave you checked for ACL's on the device that might be limiting your ability to run the SNMP session to it? It might also be worth setting up an ACL on the device if you have access to see if the traffic is actually making it to the device. A permit statement with the log statement on the end will show the connection…

Depending what information you are looking to be proactively alerted about there may be an alternative. Can you offer any more information about what you were after? An email on the top sender seemed slightly superfluous when you could just get the report writer to email you a custom report on a set criteria over a set…

The existing CBQoS reporting is handy, but enriching that would certainly be beneficial (per policy, site comparison, load vs drop things). On the QoS front being able to have the NTA offer some policy suggestions based on traffic flow data would also be good. I mean I realise you can sort of do that now if you leverage…

You might be able to leverage the IPSLA module to collect this data, albeit with different probes aggregating it together. If you set the probes on the mailserver itself you could ICMP RTT to the end point, TCP connect to the endpoint, DNS resolution for some hostnames and try and aggregate those scores together to give…

Hi There, Are you currently using the IP-SLA add-on to monitor the HTTP lookings from a network node? If so you could create a custom view in the portal for that particular host (especially if it was a machine/device acting as a pure probe) and monitor that devices SLA probe, CPU usage, Latency, Memory etc all in one…

Hi, I can't comment on behalf of SW in terms of support, but it depends on your definition of support? SNMPv3 is a standard and OrionNPM certainly supports V3 conversations to multi vendor hardware on my network but down to specific OID's for leverage in the vendor private MIB thats another matter. That said, the customer…

Hi there, Just so I can clarify, are the Wifi and the LAN's connected to seperate network segments or the same network segment? In theory you can control your DHCP scope via the MAC or VLAN or similar functions to ensure they get seperate address scopes but you'll have to make sure the route table in your laptop stacks…

Hi, I'd be curious to know why ultimately you'd be interested in leveraging that? Whilst LAN to LAN packet transfer is ultimately going to be MAC driven on L2 segments, the traffic flow should still be IP based and most flow exporters sit at the L3 domains in a network? Strictly speak netflow is an IP flow service to it…

I can confirm the previous update, we run MPLS networks with CPE flow exporters within the VRFs however when the VRF finishes we sometimes look to take management traffic out-of-band to make it a little more secure, Plain or IPSEC encrypted GRE tunnels are perfect for this as they allow normal routing for networks within…

Hi There, We often run Cisco DHCP via routers for our customers on their MPLS network, particularly those with VOIP phones. If I can be of any help, by all means give me a shout. :) I have a test network I run here for Dev work and also have a Dynamips network I can connect up to a PC with emulated 2600/7200 routers (for…

Hi There, Did you shut all the current services down before you did the repair? I'll be honest and say I'm not an expert in servers (Networkings more my arena) but it seems to suggest that a port being used for part of the process is in service and cannot be contacted by that part of the program. It refers to the socket…
