Hi Surendra, I was just given this task to see how i can configure a second ssid for guest access in our environment. this is our network setup prior to this request: Internet----Firewall (not ASA)---ce520---C1131AG and CME router is also connecting to the ce520 switch. we only have two vlans: one for voice and two for data. Presently, there is no vlan configured on the AP because it on broadcasting ont ssid and wireless users gets IP from a windows DHCP server on the LAN. the configuration on the ce520 switch port for the AP and other switches say access vlan is the DATA vlan which automatically becomes the native vlan for all trunk port connecting the AP and other Stiches to the network. Now with this new requirement, i have made my research and i have configured the AP to broadcast both the production and the guest Vlans. The two vlans are 20-DATA and 60-Guest. I made the DATA vlan on the AP the native vlan since the poe switch is using the DATA vlan as native on the trunk ports. I configured the firewall to serve as DHCP server for the guest ssid and i have added the ip helper-address on the guest vlan interface on all switches while the windows server remains the dhcp server for the production DATA Vlan. I have confirmed that the AP, switches can ping the default gateway of the guest dhcp server which is another interface on the firewall. I can now see and connect to all broadcasted ssids but the problem is I am not getting IP addresses from both the production dhcp server and guest dhcp server when i connected to the ssid one at a time. My AP config is attached below. Please tell me what am I doing wrong. Do i need to redesign the whole network to have a native vlan other nthan the data vlan? Does the access point need to be aware of the voice vlan? Do the native Vlan on the AP need to be in Bridge-group 1 or can i leave it in bridge-group 20? I will greatly appreciate your urgent response. Thanks in advanced. ... View more

Hello All, I wonder if CME routers can be configured in a redundat mode for both Internal calls and PSTN inbound and outbound calls. Since we have redundancy for CUCM can any one tell me if it is possible to apply the same concept to CME. I know that this will require the two routers to have the same or similar hardware configuration. I want to setup two CMEs so that when one CME becomes unavailable, all call processing should fall to the second CME or to share the call processing load between the CMEs. Is this possible? If yes, what type of spilter do I need to connect my PSTN lines to the FXO ports on the two routers? What other components is required? Where can I get the step-by-step guide to achive this. I will appreciate any suggestion. Thanks in advance. ... View more

I need to ask some questions regarding the USB ports on these NAS devices. From experience with other NAS devices, direct connectivity to a computer is not possible via the USB ports. Can any of the USB ports on the Cisco NSS NAS devices be connected directly to a computer and detected like a normal external drive? Are there any other Cisco products that can be connected directly to servers via USB and can have a large amount of disk space like 2TB and above? Can any of these NAS devices withstand power surges and run 24 x 7 like servers? These NAS devices are to be used with Symantec Backup Exec and System Recovery products which require to be online 24 x 7? Any response at all is highly welcome. Thanks in advance. ... View more

Hello All, Can someone tell me if I can bundle 2x2MB E1/T1 cards to get one on cisco 2900 series router. We have purchased 4MB speed from the ISP so we need a device that we can use in other to maximise what we have paid for. Is it possibe to use 2900 series router to achive this? If yes, which of the 2900 series router can achive this. I know 7500 series router can do what I want but we need to go for lower model because of budget contraint.
