Cisco Switching/Routing :: 4506 - Show Authentication Session On Interface

May 17, 2012

I'm dealing with a 4506 switch that whn I try to apply "sh auth sess int xx" I get "Invalid Input Detected" ... Is there any way that I can get the authenticated session over a port even if I can't apply "sh auth sess int"?

Cisco Switching/Routing :: 3750 - Show Interface Vlan (ID) Doesn't Show In / Out Traffic Rate

Mar 13, 2013

I have configured a vlan interface on a 3750 switch. there is aprox 4Mb active traffic flowing through the interface, but when I do a "show interface vlan (vlanid)" the output show zero bits in and zero bits out. Its a typical L3 config with one IP on the vllan interface acting as the gateway for the VLAN devices. Is this a normal behaviur ? and if so is there any way to get the traffic in/out stats. The end PC/devices are connected to this switch via an L2 TRUNK and I dont have access to the L2 switch on which the actual devices connect. so cant get the real time stats of those interfaces.

Cisco Switching/Routing :: 4506 - Interface Access-list

Nov 14, 2011

I have one computer connected to the 4506 that management does not want this PC to have access to anything on our network except our DHCP server and the one printer that resides on our network.  I created an extended access list as follows.  Our network is the 10.10.x.x and the external addresses the PC needs to access is 11.1.x.x.  Once this PC is rebooted, it is unable to access DHCP to get the needed IP address it bounces back to a 169.x.x.x address and stops working.
 
Extended IP access list 2000
permit tcp host 10.10.200.242 host 11.1.200.1                           (gateway)
permit tcp host 10.10.200.242 host 11.1.2.151 eq smtp              (access from the pc to external server for smtp)
permit tcp host 10.10.200.242 host 11.1.2.149 eq 5721              (access from the pc to external server for remote access)
[ code]...
 
Then I applied the access-group 2000  on the interface the PC is connected to. What am I missing for DHCP to work and for this PC to always get the ip address that is reserved?

Cisco Switching/Routing :: 2960 - Dot1x Authentication Session Id Not Clearing

Nov 2, 2011

I am seeing the following behavior when computers move from one switch to another with dot1x ONLY when there is a 'stupid' switch in between.
 
computer --------  'stupid' switch ------- 2960
 
dot1x is working fine but when the computer is disconnected, the port still shows the authentication session id so when the computer connects to another port or switch, authentication succeeds but traffic doesn't pass. While I'm almost certain that the culprit is the 'stupid' switch that doesn't clear the session id, I have already tried another one and the problem remains so I'm actually just asking for a confirmation that all these 'stupid' switches present this behavior and if there is a workaround in this case.

Cisco Switching/Routing :: 3750 Show Interface Options

Jan 16, 2012

I'm troubleshooting a 3750 switch stack problem where computers are showing input and CRC errors.  I'd like to be able to execute a "show interface" command that will show me only the line showing the switch port and the line showing the input errors, but so far I can't figure out a way of combining those two parameters. 
 
If I do "show interface | include Ethernet[0-9]�" I get all the lines showing the port numbers:
 
GigabitEthernet1/0/1 is up, line protocol is up (connected)
GigabitEthernet1/0/2 is up, line protocol is up (connected)
GigabitEthernet1/0/3 is up, line protocol is up (connected)

Cisco Switching/Routing :: Catalyst 4506 / Routing For Internal And Guest Network

Dec 19, 2011

I am implementing a guest wireless network to work alongside my internal network. The guest network will use the existing switching network and will be separated by VLANs. I have the ASA set so that traffic can get to it and out to the Internet. I can set up a workstation on the same VLAN as my guest network and can route inside my network (strictly doing this for testing purposes). Where I am having problems is with the Catalyst 4506 switches and the ip routing. I had two separate "ip route" statements defined on my switches.
 
ip route 10.200.2.0 255.255.255.0 10.200.2.254
ip route 0.0.0.0 0.0.0.0 10.100.100.254
 
I have discovered that the traffic is always following the default route despite the fact that my IP address on my test workstation falls in the 10.200.2.x network.  I was looking at documentation and found that it is possible to set up policy-based routing on the core switches. Can you have two "ip route" statements defined like this to segreate traffic or do I have to use PBR for routing (or a combination) in this case? If I define PBR then how does that impact my existing routing? I need to make sure that I can still route the existing traffic while I'm configuring this change.

Cisco Switching/Routing :: 4506 Resilient Routing Design With OSPF

Aug 27, 2012

We have 2 sites, each with 2 x 4506 switches which will be connected togther using an etherchannel. The switches will provide access ports for client devices and will be configured with HSRP to provide gateway redundancy. SW1 will be HSRP active.2 metro ethernet links will be installed in each site which will connect back to our HQ sites. OSPF will be used over the backbone to provide resiliency and to allow shortest path routing to each HQ and to prevent traffic over the HQ to HQ link.

The 4506 will be trunked togther with an SVI for providing OSFP adjacency.For the traffic flow from SW2 to HQ2, traffic will hit SW1 and then route back to SW2 and then to HQ2. Is this the best way to do this? Should a second link be connected between switches just for routing or should something like GLBP be used?

Cisco Switching/Routing :: 4506 Connecting Switches Together With IP Routing

Aug 31, 2012

CiscoSwitch1(4506) has 3 VLANs(12,13,14) and Switch2(4948) has 3 different VLANs(22,23,24) and IP routing has been enabled in both switches with SVI interfaces for each vlan. intervlan routing is works fine.Now there is a requirement to connect these switches together. Vlan 12 on the Cisco switch 4506 has to be made available from vlan 22 from Switch2(4948).  basically Vlan 12 is having a multicast source (225.0.0.0 & 226.0.0.0) which should be accessabile from vlan 22 of  cisco switch 4948.I got 2 ideas

1)  Create a trunk between these switches and configure L2 vlan(12) in cisco 4948...i know theoritically it should work but what my concern is Ip routing enabled in both switches will it create any issues? is it a gud solution to this requirement?

2) Create a separate IP network on the ports connecting to both switches and set up routes to the networks.ex- console(config)#ip route 192.168.10.10 255.255.255.0 192.168.20.1.

Cisco Switching/Routing :: 4506 / 6506 - Multicast Routing

Mar 8, 2013

I am configuring multicast in a environment where I have a 4506 at each site (4 total) and a 6506 as the core. Each 4506 is connected via layer 3 to the 6506. I have a mix of 3560s, 3548s, and 2960s connected to the 4506s and the 6506 via layer 2 trunk
 
I have multiple multicast sources and hosts communicating at a time (multiple cameras sending video / multiple computers receiving video).  So this is not a scenario where there is 1 sender and many receivers.  This would be many senders (~50) and some receivers (~10)
 
Sample Diagram:
 
->3560
|
6506 --> 4506 --> 3548
|   |
|    --> 2960
|
4506 --> 2960
|
-->3548
 
I configured ip multicast-routing on each of the 4506s and on the 6506. IGMP snooping is on by default on the 3560 and 2960 switches. CGMP is on by default on the 3548 switches.
 
I set up PIM sparse-dense mode and IGMP version 3 on each of the layer 3 interfaces for the 4506s and 6506 where they connect and on each VLAN that is sending or receiving multicast. Multicast is working throughout the network, however I am looking to verify the configuration as I scale this out to more clients on the network. 
 
#1 - Is it correct to us sparse-dense mode in this configuration?
 
#2 - Do I need to configure a rendezvous points using AUTO-RP? (ip pim send-rp-announce INTERFACE scope TTL). Not sure here if I need to designate this and what to choose.  Right now I do not have this and it is working, but documentation seems to infer that I need to designate this.
 
#3 - Is there any other configuration settings I should be considering?  I hard to find real world configurations of multicast as examples or people that know multicast routing well.

Cisco Switching/Routing :: PXE Failing With DHCP On 4506?

Jun 11, 2012

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.

Cisco Switching/Routing :: 4506 Switch Is Not Booting With 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.

Cisco Switching/Routing :: Catalyst 4506 Choosing Appropriate SFPs

Mar 25, 2013

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?
