I wish see the top talkers 10 at the my router 2800 IOS 12.4 (13a)
but when I run the command "show ip flow top-talkers" appear following:
% Top talkers not configured
I've set
Router(config)#ip flow-top-talkers
Router(config-flow-top-talkers)#top 10
I'm using the netflow version 9
maybe my router not support this issue ?? or it's missing some configuration.
I am really new to Cisco and having a hard time with my Cisco 2800 series.
I have two sites connected with each other Site A and Site B (Using the same Cisco 2800). Now site A can connect to site B on the Cisco and the internal network, but site B can only see the Cisco and not the internal network of site A. So all the traffic is coming in to site B but can't break out of site B. I have tried everything I can think of but again my knowledge of Cisco is not good at all.
Ever since we switched to ASR1004 running XE15.1(2)S1, we have seen that the output of "show ip cache flow" stalls and is super slow to complete. We have a few interfaces with "ip flow ingress" defined. What can be causing this slowness? Any recommendations of commands to speed up the output?
View 1 Replies View RelatedI am trying to configure the NetFlow Top Talkers function on an ASR1002 with ADVENTERPRISEK9-M, Version 15.2(4)S. With this new Hardware and Software I am surprised to see that the command:
ip flow-top-talkers
top 50
sort-by packets
cannot be found on the CLI - it's just not there.
We ahave ASA 5510 and 5520 @ our office. We are not using any netflow tools in order to get the talk talklers.As this firewalls are shared firewall (used by different Projects), we are not able to get , which project is using more traffic and which is less.

We are looking at buying some but I need to be able to export this kind of data to my managment station which is also a collector.

View 2 Replies View RelatedI have configured a vlan interface on a 3750 switch. there is aprox 4Mb active traffic flowing through the interface, but when I do a "show interface vlan (vlanid)" the output show zero bits in and zero bits out. Its a typical L3 config with one IP on the vllan interface acting as the gateway for the VLAN devices. Is this a normal behaviur ? and if so is there any way to get the traffic in/out stats. The end PC/devices are connected to this switch via an L2 TRUNK and I dont have access to the L2 switch on which the actual devices connect. so cant get the real time stats of those interfaces.

Recently we have configured few of our routers to export FNF (Flexible NetFlow), some of our router are exporting NetFlow V9 packets with fields as mentioned in the NetFlow V9 RFC. We noticed that one router is exporting NetFlow V9 with the field value different from RFC. I have attached the screen shot which shows that Field 194 is assigned for TOS. Whereas according RFC it is 5. Is there any specifc reason begind this or this is an IOS related issue.

View 1 Replies View RelatedI've been thinking about this for a while and I can't seem to find a comforting answer: Assume you have three datacenters connected over a WAN. Each datacenter has its own Internet and firewall, and each firewall has a trusted network, untrusted network (Internet), and DMZ: [code]
-DMZhostA has inbound access from the Internet over port X.
-DMZhostB has outbound access to DMZhostC over port Y.
-DMZhostC has outbound access to the trusted network over port Z.
If DMZhostA gets compromised from the Internet, the attacker can indirectly access the trusted network through DMZhostC, assuming the services running on the given ports are vulnerable/poorly secured.How do you track this web of access? This is a simple scenario with just three firewalls and datacenters, but it gets proportionally more complex and harder to track as the network gets larger. Manually tracking the traffic flow seems tedious, slow, and inefficient.
My question is pretty straight forward but here is some background information. I would like my browsing traffic to funnel through my phone's 3G or WiFi connection. Is there any information out there on how to direct the browser to use the second internet connection? I was thinking about setting up a VPN using the second nic and somehow instruct the browser to use the specific proxy. I have no idea if that is even possible though.
The need for this is pretty simple. I do not want my browsing habits being logged by my company's network. Also while maintaining the current corporate connection so Outlook and RDP programs continue to function correctly.
I am fairly new to configuring ASA's. I have an ASA 5505 with one outside interface and three inside interfaces (inside1, inside2, and management). I need inside1 and inside2 to be able to talk to eachother but cannot work out how to make this happen. They are both configured to the same security level and the 'Enable traffic between interfaces with same security level' box is ticked. I have also tried adding appropriate NAT and Access rules. The packet tracer suggests the rules are correct for allowing traffic flow between interfaces but obviosly this may not be the case.
View 14 Replies View RelatedStruggling to find any documentation that states both "ip accounting & netflow" are supported on the new ME3600 switches. I have tried both a 12 and 15 release of software. Netflow produces no data what so ever, ip accounting only produces data (of the global network) when configured on my uplink (running MP-BGP network) unable to get specific data for user networks in seperate VRFs. Is this a case of the commands being there but not being supported?

View 4 Replies View RelatedThe network scheme is this one, I have Lightweight APs distributed and a pair of WLC 5508 centralized. We use a pair or SSID for all the branches, concretely Voice and Data.
All the branches has a local DHCP Win2k3 Server, and APs get its IP address correctly from the local DHCP, but the wireless clients obtains the IP address from the centralized DHCP Server, because all the DHCP traffic go through LWAPP/ CAP WAP tunnel to WLC.
I want that the clients get its IP address from the branch DHCP, i have reading and i think that we need to use H-REAP with local switching configuration and the correct vlan mapping in local switch and H-REAP for it works that we want. Is it correct? Is possible that the client obtain the IP address for the local/branch DHCP Server instead of the Local DHCP?
how to configure WRT54GC compact Router if the data should be configured to flow from PC1 through Switch to Router and then to PC2 back through Switch in the following configuration?
