Turned up a new colo service last week using some PIX 515E firewalls and two Cat 2950 series switches. I have attached a diagram of the layout which I have used elsewhere with good success. Basically I have two switches connected together via port channel (2 ports). The colo facility gives me two HSRP enabled links, of which I plug one into switch A and the other in switch B. The PIxes are a failover pair with the primary plugged into the same switch A as the primary HSRP link.The backup PIX is plugged into the backup switch where the backup HSRP link is. When I unplug the primary HSRP link the PIX can ping the HSRP gateway still, but nothing beyond that. Nothing gets it to work until I plug the link back in.
The only thing I could see that might cause an issue is the 'ip verify reverse-path' command on the PIXes. But even the switches cannot ping out beyond the HSRP gateway. Just seems like all inbound routing stops. I am not sure what the colo facility has going on their side but it seems like they are using just some Cisco 6509s and doing HSRP between them. Seems pretty simple but so far this is proving un-usable as is.
The PIX BTW just uses a default route to the HSRP gateway.

I need to configure DSL Load Balancing on Core Cisco Switch 4506-E. I have a Router Cisco 2811 with 2GE Ports and a Firewall Cisco ASA5505. I have 8 Physical DSL Connections with 1Mb each. I need to combine that 8 Mb on Core Switch and allow each end user to access the Internet via the available DSL connection which means that every user has 8 Mb available.

I am in the process to route two buildings together. Both building have the same network setup. 2 Core Switches 4506-E Chassis having glbp for layer 3 redundency on about 20 vlan in each building with default intervlan routing in place.Below is a simple sketch of how these are connected. Blue lines are still not connected...
What I need is to setup routing onto the blue fibre links so that networks from building 1 can reach networks on building to and vias versa. I would also need to implement some sort of redundency since I have to fibre links between the 2 building.

I have a problem about user tracking for LMS 4.0.
For example:Switch 4506 send the endhosts for every VLAN that it has configured, except for one, but I can see that VLAN is configured over the switch.
are there problems directly with the connected endhosts over this VLAN or is it a problem about configuration for user tracking settings ?

I have a Cisco 4506 With IOS 12.2 54SG1
Iam new on Acs 4.2 and i want to use Certificates to authenticate my windows XP Client and Igels.
On Windows Xp i selected : IEEE 802.1X Authentication enable EAP (Peap)
But i dont understand the Certification of ACS 4.2.
I generated a Self-Signed Certificate. Is this right ? and under installed Certificates the Certificate Status is okay.
Do i have to create for each windows Machine one user Account under user-Setup to authenticate the Machine?
Where do Windows Xp know whitch Certificate he have to take ?
I configures the Switch on Global Configuration like this:
aaa authentication login default group tacacs+ enable
aaa authentication enable default group tacacs+ enable
[Code].....
Iam triying to configure ist szenario till 4 days and it still dont work.. On Windows i Only get the Error" authentication failed" on the Switch the same : dot1x : Authfailed

I am getting High CPU utilization in one of my switch which has many layer 3 vlan interface and many other routing interface.In the o/p of show process cpu i get 64 % CPU utilization. The o/p is as below
PID Runtime(ms) Invoked uSecs 5Sec 1Min 5Min TTY Process
30 37656252881151776906 3269 62.31% 63.95% 64.82% 0 Mgmt LoPri
And rest of the other process are very normal. Only cat4k Mgmt LoPri is consuming very high cpu utilization. I have checked all the interface input queue and all are very normal.

I just started a new Position and they have CATos still runing on some of there 4506 and 6509 switches. I amy trying to come up with a plan to upgrade the switches to IOS but I dont know if they will take it or not. I know I need to get flash Cards to hold the IOS but i need to make sure that I get the right IOS for the Switches.

My existing 4006 chassis is using Supervisor III (WS-X4014). I have another 4506 chassis using Supervisor IV (WS-X4515) and a Net flow Services Card (WS-F4531) build on top of it.
I need Net flow Services Card in 4006, so can I just replace the Supervisor IV (WS-X4515) used in Cisco 4006? Is it compatible with 4006?

We are attempting to PXE boot from clients obtaining their DHCP lease information from DHCP pools configured on our 4506. The PXE server, and the client are configured in separate VLANs. We have configured option 66 to point to the PXE server IP address, and the bootfile option to point to the PXE boot configuration filename. On the client side SVI, we also have configured the ip helper-address command to point to the PXE server (which also acts as another DHCP server for redundancy).
The PXE boot continuously fails stating it is unable to find the configuration file. If we remove the DHCP pool from the 4506, and allow the client to receive their DHCP lease info from the secondary server (Windows 2k8 - same server as PXE server), they PXE boot with no issues.
We have no problem obtaining DHCP info, just completion of the PXE process.

Yesterday I've faced a Problem that is not letting me boot with the new IOS.
Actually I'm planning upgrade IOS which supports SSH. As part of plan I've downloaded the new IOS image and uploaded via TFTP server to the switch.
After uploading to the switch. I've verified image and MD5 hash also. Everthing is fine. Then after I set the boot variable for the newly uploaded Image.
When I'm rebooting the Device it is not taking the new IOS. It's booting with the OLD image. Even It's not showing any error message while rebooting (ACTIVITY FILE ATTACHED FOR YOUR REFERENCE) I can't take risk by deleting the old IOS.

Vlan interfaces configured in he switch are not showing input and output traffic, whereas the traffic is seen on the Gig interfaces mapped to the respective vlans . We also tried configuring the load-interval 30 , but there is no change . Interace 3/5 is mapped to vlan 5 . For this issue we have also done the IOS upgrade from 3.1.1SG to 3.2.5SG recently still the issue is same. [code]

We have just purchased and installed a 4506-E chassis. It contains a supervisor, two POE blades and 3 non-poe blades. Version is 12.2(53)SG1. Anyhoo, one of the ports isn't providing power to an IP phone. We can plug the phone into any of the other POE ports and it works fine. Is there a way to test an idividual port for POE problems? What could the problem be? The port works for normal data but will not provide power.

a 6509 and a 4506 with 2, 1gb interfaces in a portchannel. Bring it up and everything is fine. Save the config and reload either switch and the interfaces stay in Not Connected state. Either doing a No Shut or a physical unplug the SFP and plug it back in will bring it up with no issues. Interfaces do not go into Err Disabled state they stay in Not Connected like there is no fiber plugged into it. No error mesages in the log. The Just the Interface is now up.Both are running very new code,
6509 - s2t54-ipservicesk9-mz.SPA.150-1.SY1.bin ( 15.0.(1)SY1 )
4506 - Version 03.02.00.XO

I have "inherited" a Catalyst 4506 with IOS version 12.2(20)EWA1 and Supervisor IV already installed. We recently purchased a second Supervisor IV and I am looking to install this second supervisor for redundancy. Is there anything special with installing a second supervisor or so I just physically install the new supervisor and the IOS will automatically set everything up?

I have a remote site with 2 WAN links.Link 1 MPLS with telecom provider managing the PE and advertising EIGRP routes to my switch(3750-E stack).Link 2 Directly connected to core site switch (4506) and advertising EIGRP routes.
It looks like this:
-------- Provider MPLS Cloud ------- GI2/0/1Remote Site (3750-E Stack)
Core Site Switch(4506)----
gi4/2------------------------------------------------ GI1/0/1Remote Site (3750-E Stack)
When both links are up MPLS is disrupted from other sites (that have MPLS only) to the core site. I was unable to get a route list to see what exactly was going on before shutting the directly connected link down.What i'd like to have is:Use MPLS as my primary link as it is fully meshed with all my remote sites (and not just the core) and have the directly connected link as my failover in case of issues with the primary. I assumed putting a delay 1000 on the directly connected link at the remote site would have been enough but it looks like both were active and leaking routes all over the place Is there a way to set this up that the MPLS link is favoured and if it loses routes to that specific remote site it would failover to the directly connected link?
Here is my current configuration for EIGRP on the remote and Core sites:
Remote 3750-E
router eigrp 100
redistribute connected
redistribute static
passive-interface default
no passive-interface GigabitEthernet1/0/1

Our ACS v5.2.0.26 started to drop connection from wired and wireless connections, with a "Radius Request Dropped" message. The detailed message is : "RADIUS Request dropped : 11051 RADIUS packet contains invalid state attribute".This message is usually preceded with a "RADIUS Request dropped : 24444 Active Directory operation has failed because of an unspecified error in the ACS" error.The communication with Active Directory seems to be ok since worstations are getting a valid ip adress when connected to a non 802.1x switch port (Cisco 4506).

My inherited network has a Cisco Catalyst 4506 with a WS-X4124FX–MT fiber card that connects to twelve Cisco 2950 switches over 62.5 micron multimode fiber at 100 Mbps. I do not know my run lengths (or even where the conduits run), but the furthest switches are well over a thousand feet from the server room. Any appropriate test equipment to provide this information soon.
We are looking at upgrading the main switch to a Catalyst WS-C4507+E with two WS-X4712-SFP+E cards and the closets to Cisco 2960S-48TD-L switches. Assuming this is a reasonable move, my question is about choosing the appropriate SFP’s for our current and future needs.
I am aware that 62.5 micron multimode fiber is the least favorable for extended lengths, but I will not be in a position to replace it for at least a year. If I purchase 10 Gbps modules, like the SFP-10G-SR or SFP-10G-LRM, can they “throttle down”, either automatically or by setting a parameter, to communicate at slower speeds over distances that exceed their 10 Gbps maximum link lengths on multimode fiber?
