Cisco Switching/Routing :: 3560 What Protocol Should Configure To Prevent In Case One Core Fails

Feb 14, 2013

We have one core switch and we are planning to add a 6509.  Both are none VSS.All the access switches are Catalyst 3560 series.
 
We plan to have all 3560s to have a link to each of the core. Without VSS, it is not possible to etherchannel to both core switches correct?What protocol should I configure to prevent in case one core fails? HSRP, VRRP, GLBP?
 
Do I need to run spanning tree protocol? if so which one?What is the best way to connect from each Catalyst 3560 for load balancing and redundancy? One to each core?

Cisco VPN :: 3845 - Multiple RADIUS Authentication Groups On Single Windows Server

Feb 15, 2011

We have multiple RA VPN groups on a 3845 router.RADIUS authentication is currently happening between the 3845 and a single Windows 2008 server.  We have a specific windows group that AD users are members of, and they are allowed to connect via VPN.
 
I'm creating a new RA VPN Group, which should only allow different AD users.  Is it possible to create another RADIUS association to the same server, or do I need to authenticate against a different Windows server?

Cisco WAN :: 3845 / GigabitEthernet Port Status Up And Protocol Is Down?

Oct 25, 2011

Is the subject line status correct? I have a gigabitethernet port (3845) that went from admin down, to reset and then status Down, protocol Down. Then I had another gigabitethernt port on a different 3845 router. To show port in status of UP and protocol Down, I didn't see a reset occur on this port. Which status is correct and does the reset step affect the final status being different?

Cisco WAN :: 3845 Fails To Route?

Dec 6, 2012

I have a 3845 that will not let me ping to the internet from my PC.On interface g0/0 I have a connection to a internet connection (another router), using DHCP to get it's address (it gives g0/0 IP 192.168.0.3).On interface g0/1, I have a connection to my LAN (I assign the interface IP 10.10.1.1).
 
I can ping the router.  The router can ping the internet, do DNS resolution, etc.I have ensured routing is enabled.  The only route I have configured is a default static route: 0.0.0.0 0.0.0.0 192.168.0.1.Oddly, if I choose 0.0.0.0 0.0.0.0 g0/0, I cannot ping sites on the internet from the router.
 
I tried setting up ip nat inside for my LAN and ip nat outside for the WAN/internet uplink, but this did not work.

This was the issue, I missed finishing the NAT setup.I can make the router ping out all day, and have my PCs ping the router, but getting the connection between the two is not working.

Cisco :: 3750 Via Vlan250 From Core 6509 - Getting Connection Refused?

Apr 11, 2013

We just replaced our ancient 6509 dedicated SAN switch with a Nexus 5548UP (with 4 2248 FEXs).Our old SAN 6509 was completely separated from the Core 6509, and that Core 6509 doubled as a Datacenter switch. We've now segmented the "Datacenter" and "Core." The SAN and servers are connected to the Nexus gear rather than the Core. The old SAN had only 3 vlans. One for SAN data (Vlan16), one for management interfaces (Vlan250), and one for switch management (Vlan15).

As part of my cleanup, I want to get rid of that Vlan15 and use vlan250 for switch management. In another building, we have a 3750 that provides SAN (Vlan16) and management (Vlan250) connectivity to a single Equallogic box and a Dell PowerVault tape drive for backup purpose. That 3750 is the only device that still has an address on Vlan15 (other than the core). Refer to the drawing below.

The Core 6509 is the gateway for Vlan250 and Vlan15. I have created an interface for Vlan250 on the 3750. ACLs exist on vty connections of each switch allowing telnet access ONLY from the Mgmt 2960. There are no ACLs on the Vlans themselves.From the Mgmt 2960, I can telnet to the 3750 using either its Vlan250 IP address or its Vlan15 IP address. However, if I shut down Interface Vlan15 on the Core 6509, I can no longer telnet to the 3750, not even using its Vlan250 IP address.

The connection times out. If I attempt to telnet to the 3750 via Vlan250 from the Core 6509, I get connection refused (which I should get due to the ACL on the vty connections). I can still telnet to other devices on Vlan250 (such as the management interfaces on the Nexus 5Ks). Why am I able to telnet to the 3750's Vlan250 Interface only when the Core's Vlan15 Interface is Up?

Cisco Routers :: RV042G Connection Refused / Policy Violation LAN To WAN

Cisco Switching/Routing :: 3550 / Routing Protocol Neighbor Between SVI And Routed Port?

Apr 18, 2012

I have a collapsed core design with routed ports between all components. Access layer switches, data center switches, core/aggregation. All routed (no spanning-tree at all).Now...I have to add an IBM BladeCenter with a BNT layer 3 switch to my topology. However, those nasties don't seem to support routed ports.How can I have a routed port on my cisco switch and a standard access port on the BNT and still establish an adjacency with an SVI? I am running OSPF, but I am labbing this in my home lab with 2 x 3550s and EIGRP.
 
On SW2:
*Mar  1 00:57:00.711: EIGRP: Received HELLO on Vlan100 nbr 10.1.1.1

Cisco Switching/Routing :: Nexus 7010 / 5510 - Run OSPF As Layer 3 Routing Protocol Between VPC Peer Links

Mar 25, 2012

I have an environment where i have two nexus 7010 switches, along with 2 nexus 5510's. I need to run OSPF as a layer 3 routing protocol between the vpc peer links.  I have 1 link being used as a keep alive link, and 3 other links being used as a VpC link.
 
1) Is it best to configure a separate Vpc VLAN i.e 1010

2) Is it best to configure a vrf context keep-alive

3) just have the management address as the peer ip's.

Cisco AAA/Identity/Nac :: ACS 4.2(0) Build 124 / Failed To Initialize PEAP Or EAP-TLS Authentication Protocol

Oct 31, 2010

I replaced an ACS certificate that had been installed as follows:

1. Generate CSR file and private key file, then send CSR to GeoTrust (Key length: 2048 and Digest to sign with SHA1)

2. GeoTrust send me a certificate. Issued by "GeoTrust SSL CA".

3. Install the certificate on the ACS. Restart ACS service.

4. ACS Certification authority setup. Issued by "VeriSign Class 2 Public Primary Certification Authority - G3"

5. Edit certificate trust list and select "VeriSign Class 2 Public Primary Certification Authority - G3" as trusted.

6. Enable EAP-TLS, then restarted the ACS service. The problem is when i try to enable EAP i get the error msg:Failed to initialize PEAP or EAP-TLS authentication protocol because CA certificate is not installed. Install the CA certificate using "ACS Certification Authority Setup" page.I searched on cisco and it said to disable the CSA, but in fact there is no CSA installed on this server.

Cisco Switching/Routing :: 881-K9 - Unable To Use RIP Protocol

Jan 10, 2013

I have bought Cisco ISR 881 C880DATA-UNIVERSALK9-M with  c880data-universalk9-mz.150-1.M7.bin ios.
 
command "show ver" tell me:
 
License Information for 'c880-data'
License Level: advsecurity   Type: Permanent
Next reboot license Level: advsecurity
 
So I have advsecurity. On cisco site there  was a thing  URL

"Table 5. Cisco IOS Software Features on Cisco 880 Series: Advanced Security Feature Set (Default)"
 
that tell me I have  RIP protocol to use. But when I type "router rip" command and sub router sommands like: network, passive-interface, redistribution. There are no in runnning-config such things after all I've done. It have not been saved.
 
then the command "show licence":
 
#show license
Index 1 Feature: advipservices
Period left: Not Activated
Period Used: 0  minute  0  second
License Type: EvalRightToUse
License State: Not in Use, EULA not accepted
License Count: Non-Counted
License Priority: None

I need even RIPv2 to have simple routing information to exchange.
 
And I don't know. Cisco 880 series is G2 or G1. Cisco ISR beginning from 890 series is G2. About 880 I don't know. There no informanion about it or at least I have not found it yet. On one 891 is the same problem. When I type "router eigrp 1" everything is great. But when "router rip"  - do no work.

Cisco AAA/Identity/Nac :: ACS 5.2 EAP-TLS Re-authentication Fails

Jan 21, 2013

I configured WiFi connection on Windows XP and Windows 7 with EAP-TLS (using Cisco WLC 7.0.235.3 and Cisco ACS 5.2.0.26.10). It is configured with computer authentication and computers certificates are autoenrolled from Microsoft PKI.It works well!
 
Now I configured Windows 8 with same configuration.First authentication works but if I manually disconnect and reconnect, I got this error on ACS: 22047 Principal username attribute is missing in client certificate.In EAP packets, we could see that Windows 8 sent a TLS session ticket but session was not resumed correctly by ACS..On ACS configuration, we checked this option "Enable EAP-TLS Session Resume" with session timeout "7200".

spanning-tree vlan 1-200 priority 24576
 
1. is rapid-pvst the best spanning tree protocol to use? on some switches we have pvst (not rapid)
 2. do all switches in the LAN  need to use the same protocol?
 3. does line 3 :priority 24576 mean that someone set tis switch as root manually? how can one further enforce the backbone as root (so noone adds a old switch with lower root id)
