I wonder if there is a dos command in XP that can display all current active IPs that are on the local network's router. So that i don't need to login to router's interface and still learn all current active IPs on the local network.

I am working on a network which has two ISP connections (Active/Active) terminating on router (ASR1000). From the LAN side (6500 switch) all the traffic need to be route on ISP1 but some of the specific subnets like 10.250.0.0/16 need to be route on ISP2 connection.
I am planning to use PBR and NAT with route maps. any documents or refrences are provided.

I have a pair of ASA 5520s operating in failover pair as active/standby, having two contexts on them. I am planning to share the load and make it active/active making first context active on the primary unit and second context active on the secondary unit. My question is if this will disrupt any connectivity thru these firewalls when I do "no failover" on the active/standby and assign the contexts to different failover groups and enable the failover back.

Several interfaces have sub-interfaces, so if I'm reading correctly, I only export flow from the physical intyerface, not the sub-interfaces. Correct?I want both inbound and outbound traffic, so do I use the command twice with ingress and egress?What is the difference between V5 and V9?

ragarding AP AIR-CAP3502I cannot learn option 43 from MS server but it can learn the DHCP ip address. We have 2 sites that option 43 does not learned by new AP's but other site works ok. I tried also to delete and add the dhcp scope and same issue. My temporary solution will be creating the DHCP pool with option 43 and 60 in the access switch and it work ok, new AP's able to show in the WLC. I just need more information why site AP's cannot learn the option 43 of the MS server but other site AP's work ok. Is this IOS bug? AP's issue? MS issue?

The Cat 2960 is today used together with LLDP-MED to announce config to Aastra IP Telephones. In some cases I need to use a small switch inbetween and plan to use the Cisco SG200-08P for this. However, I would like to avoid manual config of the Cisco 200 switch.
I am looking at deploying a pair of 5585X's in an active/active multiple context state. I am creating Mulitple contexts that need to be able to route to each other. I was going to deploy a type of Gateway context that has a shared interface to all of the other contexts, instead of sharing interfaces directly between the contexts, i beleive this will work as basically i am just cascadng the contexts and sharing interfaces.
The main problem i have come across, is that if i deploy active/active across two appliances using 2 failover groups i can not see a way to route between them, for example.
I have Context 1, Context 2 and Context GW A including the shared interfaces of Con1 and Con2 in failover group 1 on appliance A with the respective standbys on Appliance 2. I have Context 2, Context 4 and Context GW B including the shared interfaces of Con 3 and Con 4 in failover group 2 on appliance B with the respective standbys on Appliance 1.
I need to be able to route traffic between Context GW A and GW B so that the contexts can communicate in normal operation and in failover. I do not beleive that I can share an interface between contexts in two separate failover groups and to be honest without adding a L3 device between the appliances i am not sure if this is possible.
I have two ASA 5510s running in Active/Active mode. I need to make config changes on them. How do I go about it? Do I power off the secondary ASA and make the config changes on the primary and then power on the secondary ASA ? Or this another way to do this?
View 3 Replies View RelatedI have an ASA5520 in location A with an ISP connection and a matching ASA5520 in location B with a separate ISP connection. We have fiber connecting the two locations and vlans passing back and forth so I will be able to configure the failover via a vlan as well as extend the ISP's to each location via vlans. The Active/Active configuration with the multiple security contexts does not seem to be an issue but how is a redundant ISP configured in this mode?We want to have context A using the ASA in location A with ISP1 as the primary and failing over to ISP 2 in locaiton B We also want to have context B using the ASA in location B with ISP 2 as the primary and failing over to ISP1 in location A Would route tracking provide the desired result? Is there a better option?
View 1 Replies View RelatedThe 6509 Series Switches support the scenario VSS Active-Active Chassis, I would like to setup both switch's as one virtual switch but working at the same time, not with Active - Stand By Chassis.
My plans it to create PortChannel accross both Switches 6509 in order to have 2 links one connected to one slot/switch and the other connected to slot/switch in the second 6509 for servers redundancy.
I faced one problem in our core switch 4507 R . Active sup lost connection and standby came active. We got lot of errors/alerts on console shown below. [Code] Also when I reloaded the switch with reload command only both sups got reloaded but I want to reload all the modules but reload command do not gives any options for that.
View 2 Replies View RelatedI have 2 asa 5520 firewalls including and 1 AIP-SSM-10 module in each of them. the configuration is set using active/active failover and context mode.
Both of them run individualy the IPS module. The IPS is configured using inline mode and fail-open option. However when one of the module fails and the state is changing from up to init or anything else making the IPS to fail then failover is detected and ASA consider it as failover and bounce context to the other unit.
IPS soft is 6.0(4) and ASA soft is 8.0(3)
I have checked cisco doc and it is confusing to me. it says: "The AIP-SSM does not participate in stateful failover if stateful failover is configured on the ASA failover pair." but it really does participate. Running is not really an option because of production network impact matter..
We have an Active/Active ASA 5520 setup, as i know in Active/Active setup there is no remote VPN access, So i could overcome this limitations?I have a solution but i dont know if it is ablecable or not? we have a spare ASA 5510, so i can use it behind Active/Active Firewalls and assign a public static NAT IP address to it and open all IPSEC and VPN ports and let the remote users to connect to it, is this ablecable setup or not?

View 8 Replies View Relatedour application team is mandating, that the solution we should come up with for SLB, should support Active/Active mode of SLB operation.
My question, is this mode of operation supported/accredited by Cisco, and what is the draw back from the traditional active/standby.
Today a bought a brand new Netgear WNR2000 router.Upon setup the wifi was working correctly. All of the lights where active and it seemed everything was in order.Because the power cord was in the way I moved it and plugged it into a different powerpoint. From then onwards my router has not been working. Only three of seven lights are active (green).
I have tried unplugging and replugging all network cords. I have also turned it on and back off, reset the router and run the initial installation program thrice.What should I do now? Nothing so far has effected it. The computer I am installing it on is running Windows XP and the laptop I intend to use the wifi on is Windows 7.
In EIGRP, if a router loses the successor to a route, and it has no FS, it goes active (starts asking all neighbors if they have a successor for that route).But if the neighbor did have a successor, shouldn't they have pro-actively told us about it when they learned it (so we already have it as the Feasible Successor?).

View 9 Replies View RelatedHaving problems with my wireless router, dropping and keeping connection active. For some odd reason I keep dropping connection either wireless or wired. I have a total of 5 items going through this router. 2 of them are wireless and the other 3 are wired. The wireless items are a desktop computer that is using the Wireless USB adapter to get online. Sometimes it drops and most of the time it doesn’t have any problems. I have a laptop that sometimes the connection goes from strong all the way down to no connection at ALL. It starts at 54MBPS to down to the RED X over the wireless manager. Forgot to mention both of these machines are Windows XP. If I reboot the laptop, it comes up without any problems.
Sometimes I tell Windows XP to manage the Wireless connection and tell it to disconnect and re-connect again, it goes. Now for the wired items, I have 2 gaming systems and another computer plugged directly up to the router. For some odd reason when I double click on the internet, on the computer that is hooked directly to the router, it says page couldn’t be found. I know that there is connection and there is nothing running in the task tray except for the Anti-Virus and Firewall. The browsers that I am using are Internet Explorer 8 and Mozilla Firefox 3.0.10. Also checked on the back of the machine to see if I have link lights and everything is flashing. Finally, when I click the homepage or refresh button about 2 or 3 times, it goes through.
think that I am overloading this Router and it can’t handle it. I might have to look into sending "Keep Alive" packet setting on the router.
On my old Linksys WRT54GL router (with its latest stock firmware)'s http://192.168.1.1/DHCPTable.asp for DHCP Active IP Table, it only shows wireless connections. How come it doesn't show wired ones?

Sometimes I need to administer the server, but always need to VPN. Can RDP be active while a separate VPN is active?
View 3 Replies View RelatedWe are preparing to upgrade from LMS 3.2 where we run 2 seperate independant instances in seperate locations for redundancy. Each instance forwards syslog traps to a seperate Openview system in the associated location. Device updates are manually done on each system.
To reduce costs and administrative overhead we are considering switching to an active-standby environment when we upgrade to LMS 4.2 where the active system would forward traps to both Openview systems.
Any experience with an active-standby Ciscoworks LMS 4.2 environment, specifically; When one system becomes unavailable (due to network, system or application issues) is promoting the standby system to active automatic?How long does it take?
Does the standby system still monitor syslog events and initiate automated actions? Where the active system stops working or hangs and the standby system does not go active?
Are there any reliability issues with database updates or synchronization from the active system to the standby system? Is there a way to test communications from the standby system for new device turn-ups without making it active?
I have installed ACS 5.2 and configured it to join the Company's Domain as an External database with Active directory 2008. I'm facing a problem that the user once authenticated using it's active directory account it's cached in the ACS and take a while for the ACS to clear this username. For example, if user TEST authenticates and then we removed this user from the AD and then tried again; it authenticates although this users is removed from the AD !!! same thing happens when we change the user group on the AD, it takes a while for the ACS to clear the old user attributes and get the new ones from the AD.
it there an aging time for this caching mechanism, or can i clear the dynamic users manually just like in ACS 4.X ?

View 2 Replies View RelatedI am trying to set up a small domain for my business. I just purchased a Windows 2008 server and would like to use it as my domain controller.Also, I just had a new ATT DSL line put in. It came with a 2Wire modem/4-port router/wireless router device, therefore the modem can handle DHCP. The line has a static IP address as well so that I can eventually use my own exchange server and web server.I have tried 2 different configurations and couldn't get either to work) I tried to put the router into Bridged Mode and use DHCP server on my server using a PPPoe connection to connect to the Internet. I was confused as to what my static IP address and default gateway of my server should be.2) Then I tried to turn DHCP server off on the server and routing back on the modem/router. This didn't work either.What method would you recommend and why? Also I have some additional questions on each method.
Method 1)
* What is the static IP address of the server. Is it in the 192.168.1.x address or the static IP assigned to my account?
* Do I need a second Nic Card And Router to connect to the rest of my network or can I use the router provide
* What would the Static IP addresses of the additional PC be. Do I need more than 1 static IP from AT&T Method 2)
* Will this allow me to use all internal IP addresses on my machines and use port forwarding if I want a specific box to be a web server or exchange server.
I know that when you create a user account in active directory, the user's computer is also added to active directory. However, in what circumstance would you add a computer to active directory in which there are no user accounts created, or used ?For instance, my Linksys wrt54g router, on the main configuration tab has a space to name the router, which is appropriate called, "Linksys", and it has space to enter it's domain name, which if I named it, I guess it would be. LinksysRouter.**.local.Why add a router to an active directory domain ?Why add any other computer to an active directory domain with no users associated with it ?
