  • How to integrate Windows Server 2008 R2's NPS with Cisco switches?

    - by Massimo
    I need to evaluate in a lab environment the use of Windows Server 2008 R2's NPS for 802.1x authentication with Cisco Catalyst 3750 switches; the general idea is to only let clients connect to the company network if they can provide valid domain logon credentials, placing them in a restricted VLAN instead if they can't. NAP would also be a bonus, but it can be evaluated later; the main point now is only 802.1x authentication. Although I have very good knowledge of Windows and Active Directory (on the Microsoft side) and quite good knowledge of Catalyst switches (on the Cisco side), I'm totally new to 802.1x; I'd really like some general guidelines and help here, and some sort of implementation guide would also be very useful.

  • How to send connection type (SSH|Telnet) info in Radius Access Requests on Cisco router?

    - by Gianni Costanzi
    I've configured the following on a cisco router: aaa authentication login default group radius local ! radius-server host x.x.x.x auth-port 1012 acct-port 1013 radius-server host y.y.y.y auth-port 1012 acct-port 1013 radius-server retransmit 1 radius-server timeout 3 radius-server key 7 xxxxxxxxx I'd like to be able to specify some radius options in order to add information about the type of connection for which a user is being authenticated, i.e. I'd like the radius server to receive in the Cisco Router's Radius Access Request information about the connection being SSH or Telnet.. I'd like to find something that automatically adds this info in the access request, without specific configurations on VTY lines dedicated to SSH and to Telnet. Any idea about that?

  • What's causing "shutdown state" after TFTP reloaded Cisco `running-config` on 871?

    - by xtian
    Cisco CCP Write Configuration borked my 871w config while I was trying to setup port forwarding. I tested the 871's flash memory with fsck and rewrote the minimal config for TFTP (which is the same for Cisco's CCP app.). Thne, I successfully uploaded a previously working running-config from Win Vista using SolarWinds TFTP Server, unfortunately the restore was not entirely successful. The old running config was saved to the 871's startup-config and I can login using console port. Some other things that are working are the hostname and welcome message but that's about it. Startup shows an error SETUP: new interface NVI0 placed in "shutdown" state after tftp. The missing light on the access point modem for ethernet link show the 871'a outside FE4 is not working. SO...what's the possible problem with reloading a previously working config (approximately 4 months with the same config) via TFTP? Is there something I can look for on the 871 to verify the config?

  • What are steps to upgrade an cisco UCS B series system vmware vsphere from 4.1 to 5.0

    - by Gk.
    I have a Cisco UCS B-series system with 1.4 firmware running vsphere 4.1 (ESX) + Nexus 1000V. I want upgrade all that stuff to vsphere 5.0 without downtime. I tried to find any documentation describe all steps needed to do it, but cannot found anything clear. Here is my plan: Upgrade firmware of UCS from 1.4 to 2.0. Doc: http://www.cisco.com/en/US/docs/unified_computing/ucs/sw/upgrading/from1.4/to2.0/b_UpgradingCiscoUCSFrom1.4To2.0.html Upgrade all vcenter, hosts+VEM, virtual machines, datastores using VMWare best practice. Is it OK? Am I missing something? Thank you, giobuon.

  • What are my options in replacing the noisy fan in my Linksys Cisco SRW2008P managed GigE switch?

    - by Fred Sobotka
    My first managed GigE switch, the Linksys SRW2008, was a dream, until it started randomly chattering on various ports. That started while I was on the road all the time, which made it take forever to diagnose, but that's a different problem. When I finally determined that the switch was bad, it was still covered by warranty by Linksys/Cisco, so I opened an RMA ticket and returned it. Unfortunately, Linksys/Cisco "upgraded" my replacement switch to a SRW2008P, which has Power over Ethernet features I never planned on using. That by itself wasn't so bad, but it's my guess that the inclusion of PoE functions in this model required a tiny, super-loud internal fan to keep everything cool. This wasn't something I wanted or asked for, but, now that I am stuck with it, I am investigating options for replacing that little internal fan with something far quieter. For example, if I attach a larger fan to the outsite of the chassis, I think it could push enough air to replace the stock fan that is currently there. Any advice on carrying this out? I have no interest in melting my switch due to insufficient ventilation.

  • How to stop split tunnelling over cisco VPN (OS X)?

    - by Notre
    I'm using OS X (Snow Leopard) and the built in Cisco IP Sec client to connect to my corporate VPN. Currently, everything works as designed, and desired for most people. However, I would like to be able to funnel all traffic (particularly all web browser traffic) through the VPN. (Note - I'm an end user here, not the network administrator). Is this possible? In searching around, most people are looking to do the opposite; break out the VPN and enable split tunnelling of data. I'd like to avoid the split tunnelling. Is there some setting I can make in my OS X client to make this happen? I ran across a post where routing table changes are made to force split tunnelling: how to force split tunnel routing on mac -> cisco vpn I'm thinking something similar to that might work, but I'm not a networking expert so I'm not sure where to start (or if it is even possible). Thank you! Notre

  • RADIUS authentication on Cisco switches: how to assign privilege levels?

    - by Massimo
    I need to configure some Cisco switches (IOS 12.x) to authenticate against a RADIUS server; the server is Windows Server 2003's IAS, and it validates users against his Active Directory domain. I know how to configure the switches to validate usernames/passwords against the RADIUS server, and I can succesfully login using an AD account; the question is: how can I set privilege level 15 for users, in order to not have to use enable each time?

  • Is it possible to do DNS-based ACLs on a Cisco ASA?

    - by pickles
    Short of using static IP addresses, is it possible to have a Cisco ASA use a DNS name rather than an IP address? For instance, if I want to limit a host in the DMZ to access only one particular web service, but that web service might be globally load balanced or using DynDNS or cloud, how can the ACL be expressed so that a fixed IP address isn't used and the admin doesn't have to keep opening and closing down IP addresses?

  • How do I configure dual WAN links for failover on a Cisco 891?

    - by Donjo
    I have a Cisco 891 that is going to be connected to 2 WAN links, a DSL connection and a cable connection. I'm not so concerned with load balancing between them because the DSL connection speed is a drop in the bucket when compared to the cable speed though it would be nice if it worked that way. I mainly just want to force all traffic through the cable WAN link unless it goes down. I'm not really sure what feature set I should be researching.

  • How to get a Cisco VPN 3000 config as text?

    - by Steven
    We would like to get a Cisco VPN device 3000 series configuration as a text file to look at the actual configuration, but apparently the interface is not a CLI but a graphical interface or menu driven. Is there a way to get access to the complete config as a text? And to copy and paste it to a text file?

  • Can IOS be upgraded on a Cisco Catalyst 6509 switch without downtime?

    - by Massimo
    There's this Cisco Catalyst 6509 switch with 2 (two) supervisor modules; one of them is active, the other is (almost always) in standby. We need to upgrade IOS; current version is 12.2.something (I can check exactly which one, if this does matter). Can this be done without service interruption? Something like "upgrade the standby supervisor, activate it, upgrade the other one"?

  • How to auto dial 9+Number on Cisco 7941 redial?

    - by NotDan
    Is it possible to set up a Cisco 7941 phone to dial 9 before the redial number? When I view missed calls, and try to redial one of the numbers, it always fails because it doesn't dial 9 first. I have to write the number down and then manually dial the 9 and then the number.

  • Is there Muticast routing support on a Cisco 3750?

    - by mrtechalot
    We have a switch (Cisco WS-C3750G-48TS) with only a C3750-IPBASE-M image (not a 'C3750-IPSERVICES-M' license). Is there any kind of multicast support here? All I need it to do is route multicast packets to an RP (ip pim sparse-mode). Do we really need the service (C3750-IPSERVICES-M) license/image?. The uplink switch is running C3750-IPSERVICES-M, but this switch doesn't seem to carry any ability to configure multicast on an interface.

  • Any problems usinga GoDaddy SSL certificate on a Cisco ASA firewall?

    - by Richard West
    I need to purchase and install a SSL certificate on my Cisco ASA firewall. This will allow my VPN users to connect to my ASA without receiving the certificate error from the untrusted self assigned SSL certificate that is currently on the ASA. I had good experiences with the SSL certificates that GoDaddy sells. However, I'm concerned about using them. On my web servers I have to also install GoDaddy's "intermediate certificate bundle". On the ASA I do not think that I will be able to preform anything like this. I do not fully understand what the "intermediate certificate bundle" does, but obviously it's important. So my question is can I use a GoDaddy SSL certificate on an ASA without my users getting any type of warning or error about connecting to a site that using an untrusted SSL certificate. I need this to be as simple as possible for my end users and warning messages are always scary :) Thanks!

  • Cisco ASA 5510 ASDM: Setting up multiple public static ip addresses on a single interface and route

    - by ssjaken
    HI, i have a cisco ASA 5510 using ASDM version 6.3 We have a webserver that is been written very specifically and i was given super direct "DO NOT DEVIATE" directions. This server has to get traffic from 3 different PUBLIC ip's that we own. (our isp gave use a block of 12 static addresses) on 4 different ports. there are the directions i was given externalIP1:22 - 172.17.5.50:22 - SSH externalIP1:443 - 172.17.5.50:23040 - SIT externalIP2:443 - 172.17.5.50:33040 - STAGE externalIP3:443 - 172.17.5.50:43040 - PROD My first question is, using ASDM (my contract employer demands i use ASDM over CLI) how do i get three public addresses to work on one interface. We are authenticating on PPPoE. I know create a virtual interface with the static address but when i do i cannot ping the address from another offsite machine. secondly, where would i put the traffic redirect in. would i go ahead and create ACL's or just make NAT routes. Thanks.

  • How to statically configure DNS servers on a Cisco router when the WAN interface uses DHCP?

    - by Massimo
    I have a Cisco router (model 887VA, IOS 15.4) used to connect a LAN to the Internet via ADSL. The WAN interface uses DHCP: interface ATM0.1 point-to-point ip address dhcp I need the router to use a statically-defined DNS server for name resolution: ip name-server A.B.C.D However, the router insists on using the DNS servers supplied by the ISP via DHCP: Router#ping www.google.com Translating "www.google.com"...domain server (<ISP DNS>) [OK] Type escape sequence to abort. Sending 5, 100-byte ICMP Echos to 173.194.116.208, timeout is 2 seconds: !!!!! Success rate is 100 percent (5/5), round-trip min/avg/max = 44/45/48 ms How can I tell the router to ignore the ISP-supplied DNS servers and only use the statically-configured one?

  • How to get access to console to reset Cisco 3750?

    - by genehack
    I acquired two Cisco 3750 switches from another part of my organization. I was able to complete the standard password/config reset procedure on one without any issues -- boot it, put it into express config mode, telnet in, reset the passwords, etc. The second one doesn't ever boot to the point where it displays anything on the console. When power cycled, the 'SYST' light flashes green a few times, then comes on a solid green and stays lit. None of the other lights ever flash or light up. Holding down the 'MODE' button for up to 30 seconds produces no noticeable effects. Nothing ever comes out on the console. Since I was able to configure the first one without any problems, I know my connectinon is good -- console port configured right, good cable, etc. Is this just a hardware problem with the switch? Is there any way I can recover from this and get the switch back into a state where I can configure it?
