how is the IP configuration for this Fast Ethernet F0.
This is because usually we only assign IP to the BVI interface. Is it after that, the Fast Ethernet F0 automatically also be assigned the same IP?
As such, when goto the Fast Ethernet F0 by CLI, by using no shut then this will Enable the Fast Ethernet Port?
I have a Cisco 2600 series with 2 X Fast Ethernet ports and I would like to configure the cisco to perform the task if it is possible.The scenario is:
2 networks:
F0/0: 192.168.x.x
F0/1: 10.1.x.x
No communication between them except one way multicast from F0/1 to F0/0.

View 4 Replies View RelatedI currently have 2 PCs that are directly connected to each other via a 1Gbs Cat6 connection.I don't currently have a 1Gbs router so what I am doing right now is unhooking this connection and reconnecting both machines to my router when I need internet access. I have ordered some USB Wi-Fi adapters so I can have both machines access the internet that way whilst still use FTP between them on the 1Gbs line.If I were to scrap that idea and get a 1Gbs hub, connect both PCs straight into that, and then also connect the hub to my 100mbits router, would the 2 computers be able to communicate with each other at 1Gbs and then talk to the router at 100mbits, or would the whole network run at 100mbits.I don't really want to have to shell out on a 1Gbs router as I don't need anything else on the network to run at that speed.

Is there an expansion I can get that allows me another Ethernet port. I have thus far assumed that all of the WIC cards won't allow me to attach to an Ethernet LAN.

View 6 Replies View RelatedI had a question regarding the Cisco 2811. I tried fitting an NM 2FE-2W card and the fast Ethernet interfaces of the module never get recognized. Is there a special command to enable it or isn't the module supported at all by the router. If not , is there a way to have the router possess more than the 2 Fast Ethernet interfaces it already has? Let me know if any more info is needed from my end.
Another question I have out of curiosity. Is it possible to make the controller T1 port of a VWIC 1MFT-T1 or a VWIC 2MFT-T1 act as a fast Ethernet.
Is there a keyword that we use under the interface to specify that it is purely management?
We need to assure that the subnet and any node on that subnet is not shared with the default routing table.
how do we set the gateway for the management interface if the node we are sourcing the ssh session from is on a different private subnet?

It is a single router with dual ISPs. It is a 2800 and there is failover configured. I have implemented object tracking and the feature works great except that lately, whenever there is a lot of traffic coming perhaps from the internal users, we start getting intermittent outages.
I have gone deep into looking into this problem and have determined that our ISP#1 does not have any problems. What I think is happening is that whenever the router receives a lot of packets (30-40 users on the internal network) destined to the outside, the router CPU maybe gets too busy and the router then believes that the objects are no longer reachable and it triggers a failover which causes the router to re-direct traffic to the ISP#2. Then, because these are just quick burst of traffic, in the next 30 to 45 seconds after the router re-directed the traffic to ISP#2, the router object tracking engine detects that the objects are now again reachable and this then causes the router to re-direct all traffic back to ISP#1.
This cycle then continues all day on how to prevent this.
Is there a way to perhaps tell the router to completely shut down the interface facing ISP#1 whenever there is a hicup and to keep it shutdown for at least 8 hours? This way I can prevent the router from going crazy.
Or is there a way to perhaps prevent this at the internal (LAN) interface? Are there some metrics like QoS that I can implement on the internal Fast Ethernet Interface to prevent the burst of traffic from eating up the CPU?
I am troubleshooting interface resets on a 3660 connected to a 3550 over Fast Ethernet. I have hard coded both sides for full duplex and 100Mbit. The 3660 is incrementing interface resetes about 4-6 times a day and the 3550 is clean. I have noticed this in other similar configurations as well.
View 4 Replies View RelatedMy Belkin F7D4301 Router has the fastest wireless speed of maybe 2MBps but wired with a cat5e cable to my asus laptop of almost 7MBps. I have a one smart TV, one blue ray, one roku, and a nexus 7 using the 2.4 channel.
My Wireless 2.4 settings are channel 11, Extension channel 7, Wireless mode N (have tried with just g and b, g, and n modes), Bandwidth 20/40, Protected mode on, QOS off.
I've talked to Belkin tech support, they are the ones who had me set up my 2.4 channel this way but my wireless speeds stay just under 2MBps, they just want to keep sending me the same model Router because they think each of the new ones they send me is defective.
Am I doing something wrong or is 2MBps the best wireless speed I'm going to get?
Trying to set-up a p2p link between a L2 fast ethenet module (within a 2900) to a 6506.Have created a subinterface SVI on the 2900 and put the fast ethernet port in the respective VLAN. However on 6506, am I correct in thinking I can do a no switchport and just create a L3 interface? Do I need to put the 6506 in the same vlan and the fast ethernet module and create a L3 SVI on it? As it's not a trunk port between the 6506 and the fastethernet module, the packets won't be tagged?

Would the fast ethernet devices slow down the entire gigabit networking to 100mbps connections on my floor - similar to how a wireless n network running at 300mpbs must slow down to 54mbps when a wireless g device is connected to it?
I'm trying to test fast roaming using a Cisco 2100 Series controller and 2 1140 APs. The initial authentication succeeds fine and the wireless connection works ok using WPA2+CCKM and LEAP with a Cisco ACS radius server.The problem is that the client does not attempt to preauthenticate with the other AP because the RSN Capabilities IE in the AP beacons and probe responses do not set the RSN Preauthentication capable bit. I can't figure out what it takes to get the APs to indicate to clients that it can do preauthentication. I'm been crawling through all the documentation I can find, to no avail.
