Cisco :: Determine How Much Traffic Is LAN Vs WAN
Aug 30, 2011
I have a site with a 1700 router connected to a 2960 switch. For some of the computers on site I want to determine how much traffic is local to the LAN and how much is going across the WAN.
One strategy I've come up with is to reset the interface counters on the switch ports to the machines in question and after some time compare the total bytes in and out of the interface with netflow data from the router. My only concern is that netflow is not completely accurate about the amount of data that has passed through an interface.
Is there a better or more accurate way to accomplish my goal?

We are trying to setup a WAP4410N with 2 SSID's. One SSID for our private network and the other for guest internet access. On the VLAN and QoS page there is a setting for priority. What would be the suggested values for this setting? We obviously want our private network to receive priority over our guest network.Also, does VLAN Tag setting need to be on Tagged to determine private from guest traffic?

I'm the sole IT worker at this company and I specialize in everything but big, corporate networking so here's a dumb question. How do I determine the IP address of one of our two switches? I need a list of MAC addresses of connected devices so I can relabel all the cables that were mislabeled (and this is a managed switch). For the other switch, which was put in by someone who knew what they were doing, you just type ss3900 into a browser and tada, 3com Superstack 3900 login so apparently someone did some fancy DNS stuff or whatever.
For this HP Procurve, the idiot before me who got fired for completely screwing up everything didn't leave any documentation or labeling and didn't use the same IP address as the Cisco switch that was pulled out. Obviously the switch is invisible to my PC from an IP standpoint

J've just bought an Asus RT-N66U router and I'm setting up a broadband credit card machine to go into it (rather than transmitting data over the phone line).I need to know what the status of DHCP and MAC are on the router but I'm not sure how to find it.DHCP needs to be on and MAC needs to be off.

I am new to Cisco Nexus and recently my company auditor flagged out that IPv6 is enabled on our Cisco Nexus 7000 device when we are not IPv6 ready.
The auditors have flagged this out due to the following default CoPP configuration:
ipv6 access-list copp-system-acl-bgp6
ipv6 access-list copp-system-acl-hsrp6
ipv6 access-list copp-system-acl-icmp6
ipv6 access-list copp-system-acl-icmp6-msgs
ipv6 access-list copp-system-acl-ntp6
ipv6 access-list copp-system-acl-ospf6
ipv6 access-list copp-system-acl-pim6
ipv6 access-list copp-system-acl-radius6
ipv6 access-list copp-system-acl-ssh6
ipv6 access-list copp-system-acl-tacacs6
ipv6 access-list copp-system-acl-telnet6
ipv6 access-list copp-system-acl-tftp6
Does the default CoPP enable IPv6?

Do you know an easy way to determine the physical location of the device were an IP address is attached? IP Geo location doesn't work well.Is something like this possible? I know it could be if you are the network administrator and know the location of your equipment and stuff.

I was attempting to troubleshoot a logon problem with some machines, when it was finally revealed that there was a managed switch between the host and the target preventing this.
How would I detect this in the future? (A tracert showed nothing between host and target.) Would Wireshark show me this info, with reduced TTLs?
getting a picture of all devices between a host and a target?

problem is my brother has been playing with its config page. he changed the IP Address of the modem and disabled DHCP. he forgot what IP Address he inputted on the config page. I tried resetting the router with the small button on its side. Nothing happens. all the lights blink when i pushed the reset button for 10 sec. but nothing happens. i still can't access its default IP which is 192.168.1.1 IS there anyway to determine its IP Address even if DHCP is disabled ?

Should the DIR-655 list all devices that are accessing either my WAN or another device on the LAN, assuming there are no other switches on the network, and all traffic is going through the DIR-655?
I was trying to determine the IP, and MAC address of an AT&T Microcell connected to my network. I have no physical access to Microcell. I have been able to find the IP address, in the logs of the DIR-655, but nowhere else. Shouldn't it be listed under SETUP -> NETWORK SETTINGS -> NUMBER OF DYNAMIC DHCP CLIENTS?

The support and registration pages for the E4200 wireless router ask whether I have a V1 or V2 router. There is no place on the actual router that identifies it as V1 or V2, and the Cisco Connect application doesn't display this infomation either. What I do know is the following:
Model name: Linksys E4200
Model number: E4200
Serial number: 01C10C18104423
Firmware version: 1.0.03 build 14
Software version: 1.4.12005.2
How do I determine if this is a V1 or V2 router? The software updates are version specific.

I'm attempting to configure qos on our ASA 5505 and I'm not sure how to determine what our average and burst rates should be.The applications being used will be RDP over a ipsec tunnel, so it is somewhat sensitive to latency.The final setup will be a 1.54Mb T1 line, but in testing I have a DSL connection with .70Mb U/L speed.

We are trying to replace the CSS between our firewall and DMZ with a BigIP. Among it's other functions, it will act as the router between the firewall and the DMZ. To make this work, I need to assign vlan tags values for the vlans I create on the BigIP box and these must match the tags on the cisco switches (3550's) How do I find this information on the switch?

I have a client devices constantly sending data (~ 13 kb per second) to a server through a Cisco AP1241AG (802.11g).I use Iperf to test throughput, but I am having a difficult time determining what an acceptable throughput rate would be.I know in "theory" the best throughput rate I could get is 54 Mbps, but since my client devices only send 13 kbps is 1 Mbps more than enough? or is 13 kbps the low limit for my throughput test?

I am not very computer literate, so this will seem like a stupid question. How do I determine whether a computer has wireless connectivity?
I have a Dell Dimension 9200 running Windows Vista that I bought in 2007. Previously, I have connected it to the internet using an ethernet cable to my router, but this is no longer possible now that my new computer is using the ethernet connection. I want to establish a wireless connection between my older Dell Dimension 9200 and my router, but I don't know how to find out whether the computer is capable of wireless connectivity.

I have an E1000 linksys router. I am trying to determine the admin password. I have looked at seeral entries regarding this. I do not have CICSO connect installed. Not sure why. The router works fine. I have the CD that came with the router. I have also downloaded current version of connect software. Both of them want to config the router. The first item asked for is the admin password. I know I press reset button. I am trying to retrieve password without doing that.

There is a unicast flood on 3750 killing slow modem links. How to determine source MAC address of flooder? Is there a rate limit feature for it?
I know how to block it completely on port-level, but it breaks normal network operation. (when port goes down for some reason, it's learned MACs got flushed and since other hosts know MACs, they keep flooding untill their arp caches expire).

I am running "PLEX Media server" on a PC and have a "Roku" client working perfectly on my home network
I am trying to use the "My PLEX" feature of "PLEX" to stream my content to the internet and access it on a Nook or iPod from any internet hot spot. This requires that the router supports DLNA. I am not sure what this is and am not successful at this so far.
Although it may sound like I know what I'm talking about I am at my limit and do not know how to determine if my router will support DLNA.
Is it time to get a new router or is there something I need to do to the router so it supports DLNA?
