i'd like to monitor the OSPF process of my MPLS routers by SNMP. I created templates for
ospfIfEvents
ospfNbrEvents
ospfSpfRuns
ospfNbrState
ospfAreaLsaCount
but when i configure the poller i believe the data i mixed up somehow. I for example i don't get all neighbor in the ospfNbrState. i tried with snmp context configuration but i am not sure if this right what i did.
I have a problem with ME-3600x running two ospf processes. Proc1 is WAN and PRoc2 is LAN. I am redistributing routes into both directions. After a WAN outage , certain wan routes did not get redistributed into the LAN process. I had to do a clear ip route to fix the problem. Has anynoe seen such a scenario with ME-3600x or any other switch/router

View 0 Replies View RelatedI have a 2811 Router that is experiencing high CPU utilization. I have already issued the "show cpu proc" command, and everything seems to be fine (it's not a process issue) . According to our traffic graphs, we've seen that CPU is related to high link utilization, since we have 2 Fast Ethernet interfaces (Internet 4 MB and MPLS 6 MB), and when those interfaces have to deal with a lot of traffic at some hours, the CPU Load increases in the Router.
I found an article where they say that 2811 ISR Routers can deal with up to 61,44 Mbps (120.000 pps), but our router is far away from reaching that limit.It usually manages up to 16 MBPS. This router manages some services such as NAT traslation, ACLs, voice traslation profiles, policy routing (QoS), firewall and DHCP.
What can be happening to the router?.. Is it normal that when it has to process a lot of traffic, its cpu must increase up to 95%, even if it is handling just 16 MB compared to the theorical 61 MB? Is there any command or tool that I could use to troubleshoot this issue? Is there any limit in terms of WAN traffic that it could handle? How much influence do those services have over CPU Utilization?
Given these incidents, which router series could suit better in my network to avoid high CPU issues?
I have 2 ASBR routers, AGFR01RTR03 and AGFR02RTR03, performing OSPF to OSPF redistribution in both ways for the same ***. They also do summarization for our private addressing scheme. It is all working just fine for that part (neighbors, summarization, redistribution).
AGDC01RTR01 --- AGDC02RTR01 (OSPF 1000 ABRs)

AGFR01RTR03 --- AGFR02RTR03 (OSPF 1000 / 53 ASBRs)
Let's focus on AGDC01RTR01 with a specific entry here (IP subnet is fake) :

Currently the OSPF network consist of 2 segment route via static route.One is AREA 0 and another AREA 10.Both network are seperate entity, only static route to route between 2 networks.But the static route do not provide the dynamically and flexibility, I plan to run routing between 2 networks via VLAN160 and VLAN162.
I still want to manitnace it was 2 different OSPFrouting domain.Can I run OSPF with differrent OSPF porcess ID?
I am seeing an increasing number of processes on our Solaris based Ciscoworks server. The parent and the zombie processes are the following:
root@cw:/usr/ucb# ./ps -alxwww | grep 26915

This isn't the first time this happens, the last time I restarted the server and the problem disappeared for a while.
Is there a way to allocate CPU or memory resources to specific processes - similar to a QoS-style configuration where you can prioritize the processes being handled by the CPU? We have a 2811 router whose CPU periodically spikes to 100% utilization. At these times, all of our EIGRP neighbor adjacencies bounce - either a peer goodbye is received or the hold time expires.
Our thinking is that we could possibly tell the router to prioritize the EIGRP process with the CPU so that routing is maintained, even though we realize other processes (like qos or ISAKMP for our tunnels) may suffer.
I am unable to kill EPMServer processes after shutting down LMS 4.2 on Solaris 10. There are still 60 or so EPMServer processes running. Killing them manually does not work as they appear to restart again after killing. Only way to knock them off is to reboot the system. Why does dmgtd stop not kill all LMS processes and is there a patch required for LMS 4.2 or Solaris 10 that would work?

View 7 Replies View RelatedI have a scenario with a Cisco 6506 and a 7206. The 6506 is running BGP and peers with our data center router. The 7206 is a stub router off the 6506 and is used as an edge router for customer T1 circuits. I want to use OSPF between the routers to exchange connected and static routes. The problem I have is that static BGP null routes on the 6506 are overriding the OSPF routes being received from the 7206. Example: The 6506 is advertising a class C network 192.168.1.0/24 to our data center. The 6506 does not utilize the 192.168.1.0/24 network. It is only used on the 7206 for customer T1 circuits and is carved up into /29 subnets. So the 6506 has a static route: ip route 192.168.1.0 255.255.255.0 null 0. Today the routing is accomplished with static routes on the 6506 for the 192.168.1.0 networks on the 7206. Using OSPF the 7206 advertises /29 links back to the 6506, but when I withdraw one of the /29 static routes from the 6506, the /24 null route takes precedence over the more specific /29 routes and the traffic is black-holed on the 6506. how can I get the OSPF routes to look preferable to the /24 null route on the 6506?

View 1 Replies View RelatedWe just recently purchased a 3945 ISR G2 router and have a SRE-910 module (with two hard drives) configured in a Raid 1. We are running a stand-alone version of ESXi on the service module and I'm trying to figure out how to monitor the status of the Raid on the drives (along with other health issues). SNMP has revealed nothing so far and even opening a support case for which MIB's to use has proved fruitless. All the documents I find on monitoring the modules say to use LMS which is now Cisco Prime. I've downloaded the trial copy, put in the SNMP settings and scanned the router. I get device results and it shows that I have the SRE-910 module installed, but I get no other configuration / device informaiton from the module itself.
I tried to create a new Monitoring template using the NAM health as the base template (which I'm assuming this is the correct template). Unfortunately, when I actually try to deploy the template against the discovered router, I get an 'Unexpected end of list' error which makes me assume I'm still doing something wrong.

View 5 Replies View Relatedhow i can configure a second ssid for guest access in our environment. this is our network setup prior to this request: Internet----Firewall (not ASA)---ce520---C1131AG and CME router is also connecting to the ce520 switch. we only have two vlans: one for voice and two for data.
Presently, there is no vlan configured on the AP because it on broadcasting ont ssid and wireless users gets IP from a windows DHCP server on the LAN. the configuration on the ce520 switch port for the AP and other switches say access vlan is the DATA vlan which automatically becomes the native vlan for all trunk port connecting the AP and other Stiches to the network.
Now with this new requirement, i have made my research and i have configured the AP to broadcast both the production and the guest Vlans. The two vlans are 20-DATA and 60-Guest. I made the DATA vlan on the AP the native vlan since the poe switch is using the DATA vlan as native on the trunk ports. I configured the firewall to serve as DHCP server for the guest ssid and i have added the ip helper-address on the guest vlan interface on all switches while the windows server remains the dhcp server for the production DATA Vlan. I have confirmed that the AP, switches can ping the default gateway of the guest dhcp server which is another interface on the firewall. I can now see and connect to all broadcasted ssids but the problem is I am not getting IP addresses from both the production dhcp server and guest dhcp server when i connected to the ssid one at a time. My AP config is attached below.
Do i need to redesign the whole network to have a native vlan other nthan the data vlan? Does the access point need to be aware of the voice vlan? Do the native Vlan on the AP need to be in Bridge-group 1 or can i leave it in bridge-group 20?
My question is if I can configure 3 ssid, for 3 different VLAN and add the DHCP address from a WAP4410N AP, when you upgrade to the latest version of IOS I can have this functionality?

I have 2 questions:
1. Can I have 5 Interfaces configured on 5 different VLANs, each SSID on each a different Port:
Port 1: Controller management only=> 192.168.x.x /24

Port 4 :SSID 3: WiFi Guest=> 10.0.x.x/8 (Web Auth)
Port 5: SSID 4: WiFi IT=> 192.168.x.x/24 ( Radius or certificate Auth with access to the controller management interface)
2. How can I use the Controller as the DHCP server for all the WiFi traffic, and how should that be configured to work with my other DHCP server?
