some of the servers are not pinging from one switch but they are pingable from other redundant distribution switch. So I took the IP addresses from the redundant switch, with that I found MAC addresses from the access switch.But when I tried to see to which ports these MAC are addresses are connected to, multiple MAC addresses are resolving to the same switchport. like 5 MAC's are showing to 1 port and other 3 MAC's are showing to other port, like this there are many. All these MAC's belong to virtual servers.

I have buildings geographically dispersed that are configured with multiple vlans in interface groups so that I can maintain an addressing scheme of dhcp assigned addresses per building. Each building is also further grouped as AP groups. I'd like to know if by assigning the same wlan ssid to each of the AP groups, will I maintain addressing integrity for each building? I'm thinking it will work.
Do the buildings have to be outside AP range of each other to avoid problems?

Am trying to understand how we can have multiple IP addresses on a single NIC and what are the restrictions on the same. If i can have two IPs from two different networks present on a single NIC, then why would i ever get a new NIC?
Also, i want to understand the concept of virtual IP and how it fits into this picture.
I have an older DELL power edge 2800. Currently we have 2 NIC's one for the WAN one for the LAN. I wish to increase my users access speed. Can I team and or bond up to Four NIC's on the LAN side and leave the single NIC for the WAN? I am having trouble finding any info on the net for pulling this off. I have 67 users and throughput is getting a little rough.

Do I just assign them a static LAN ip address(for example 192.168.1.200), make sure the port they use is open, then type the WAN static ip address then colon and the last address? Like this.....I'm making up the WAN address....45.34.55.334:200

View 1 Replies View RelatedI currently have mutiple computers at my place. Once the computer turned on i want the option of which login for the current computer to use, it can login it current computer or the mutiples computer with their content/data all inside. So more like an computer linked. Example, it can only to A or B, A is the current computer data, while B have all the data of the different computer monitor datas, and if i login B it will show that current computer info. And same goes to the B computer, i can login to A or B on the B computer. What makes this very good is that, both the computer logins are sort of connected, for example if im on actual computer A, but logined to computer B and downloaded/changed some files/data on the B login, once i login on computer B to login B, the changes will apply even tho the changes are done in computer A.

When I tried to resolve the same domain name I got five servers ip address against the same domain name. however we given the ip reachability to only for two servers. We we try to save we get error saying that "Can not resolve the network address".
So my questions are;
- does ACS should have ip reachaibility to all five servers
- does the username/password we entered in the ACS should have domain admin rights?.
- the given AD is configured with windows NTP [URL] but when we configured ACS as windows NTP it was taking local server as active NTP..?
When we check the ACS logs, we saw the following error;
in acsLocalStore:

We are migrating from a nother brand to an ASA Cluster running 8.4.5
We have a web-server on an inside interface listening on a non standard port - 20111. We have created a static NAT translating the public ip to the private, so If I do http://public-ip:20111 it works. (we are using a seperate public IP for this service only).
Now I need to create a NAT rule that will forward requests on BOTH port 80 and 443 to the same private ip and the same port number (20111)
The Private address is 10.99.250.20 and the "public" (I've replaced it in this example) is 172.16.16.16 I have managed to create a NAT that will translate 443 to 20111:
object network 10.99.250.20 nat (Private-DMZ,Outside) static 172.16.16.16 service tcp 20111 https
But if I try to add another rule like: nat (Private-DMZ,Outside) static 172.16.16.16 service tcp 20111 http It will simply replace the first one.
Is it possible to redirect both 80 and 443 from outside to the same port number and same IP on the inside?

View 2 Replies View RelatedI have two 1142n LWP ap converted into standalone, as client doesn't have any controller there. They just want to extend their network via wireless.

client is looking for 3 vlans on the floor ( users might multiple vlans might associated same AP ). They have a dedicated DHCP/DNS server and he will be configuring 3 vlans on L3 switch with correct ip helper address on SVI interfaces.
I'm i allowed to created 3 SSID's on 1142n standalone AP ?
What would the various optiosn to achieve this requirement ? Is there any simplest way to achieve this ? Do i need to go for 802.1x ? I remember client told their users are authenticating by using AD for wired network. This is their first request for wireless environment
I read from this forum some discussion about the WLC VLAN Select feature. [URL]. I see that you can use this feature to have multiple VLANS (interfaces) to map to the same WLAN (SSID).
What I try to learn is under what scenarios would people need to have mutliple vlan mapped to single SSID?
In my environment, I have 50+ AP int he campus on 20+ Cisco 4500 switches. I have single WLAN and it is mapped to one subnet. All wireless users would be on that subnets, whereas wired users are on 20+ subnets of their own.
We are in the process of installing time clocks at some of our sites around the USA. Our security department has asked that the time clocks be completely isolated from the rest of the network. The time clocks will be administered by ADP via a centralized firewall utilizing NAT. We have multiple subnets available at each site. Let me give an example to calrify what I would like to do. Example: Site A has 10.168.19.0 /24 user subnet and is configured for VLAN1 using 10.168.19.1 on the router as the default gateway. I would like to use subnet 10.168.20.0 /24 for the time clocks, configure it for VLAN2 and use 10.168.20.1 as the router gateway address for VLAN2. This should allow me to NAT one of our additional public IP addresses to the 10.168.20.1 gateway address thus completely isolating the time clocks from the remainder of the network. Problem is I have not done this before so I'm a little confused about how to configure it in the Cisco 3750 switches.
View 6 Replies View Relatedsetting up a simple internet plan for a place, but a LAN center needs crazy fast internet, faster than most large enterprise class offices that take up an entire floor or two. Otherwise there is too much lag in games like first person shooters. We are expecting to have 60 computers, plus people bringing their own gaming rigs from home and laptops as well, xbox, ps3 and other consoles, all accessing the internet at the same time to varying degrees, with no room for lag. There is a LAN center in california that has 200 or more computers and they pay for 9 t3 lines, which is thousands and thousands of dollars per month. Plus the initial equipment to set that up from what I can find on cdw is many thousands of dollars also. Something like 10,000 for a router with 4 expansion bays, and 4000-6000 dollars for a t3 expansion card, bringing the total to around 22-28,000 for equipment to do just 4 t3's. Plus the monthly cost. Since we don't need all of the traffic to be secured like a high end business class line like a t3, I was considering what it would be like, and how one would set up, having multiple cable internet lines coming in. They make cable wic cards for cisco routers. 4, 50meg cable lines would give us 200 down and 40 up but I don't know how to make that work without having multiple public ip's. I was thinking that if I did have multiple public ip's on the network I could just divide the computers up so that they are in groups, using all of the public ip addresses for gateways, so that the load is split pretty evenly, but still, there should be a more seamless way to do this, I just don't know what it is. At the rate for business cable internet, 4 lines would probably only cost around 700 dollars a month, which is much better than probably 5 grand a month for several t3 lines.

Here, due to IP address exhaustion in my end-user network, i want to add one more subnet X.X.X.X/22 to my network and assign one IP more from this range to the above vlan to act as the gateway IP.
I have around 60 , 1142 N APs . As of now i have only management VLAN ( for IP ) & one user vlan 350 configured on the access point . All the users connect to VLAN 350 and they get IP as required.However in our new set up there are couple of requirements have come up were in SSID will be the same however we have created many VLANs for different kind of user group and all these VLANs should be mapped to this single SSID and pick the IPs from their respective VLANs .
We have done configuration on the RADIUS server side were in we have mapped the users in their respective VLANs and they are getting authenticated via AD . Now how do i map my these 4-5 VLANs in a single SSID in Access Point.
I have a situation where a user needs more than one office extend AP in his home. My office extend controller is a 5508 running 7.0.220.0.

I see the SSIDs get pushed to the AP and then it seems to restart the process never being fully operational. Is there a workaround that will allow me to run mutliple OE APs?
