Cisco Switching/Routing :: 4510 - Command To See If Port Was Ever Up And Passed Traffic

Apr 24, 2012

I am looking to find a command or counter to tell me if a cisco switch port on a 4510 was ever up and passed traffic.  I want to shutdown all unused switchports on our access switches.  But before I do that I need to make sure device is just not off or the person is away on vacation.  If I do sh int interface, is there a counter I can reference.

Cisco Switching/Routing :: Policing Traffic On 4510?

Nov 21, 2012

I have two servers on one subnet that each need to replicate to a single server on another subnet. They also need to replicate to each other. This replication is unidirectional so I will refer to the 2 server subnet as the source subnet and the single server subnet as the destination subnet. In order to keep this replication running without killing the MPLS links on either end, we are trying to use a policy-map that limits bandwidth from the source subnet.The Problem:We have created a policy that polices traffic during specific times of day and limits the bandwidth as prescribed, however, bandwidth is also being limited between the 2 servers on the source subnet which is not needed or desired.Class 512K set dscp ef police 1024000 bps 1024000 byte conform-action transmit exceed-action dropClass Map match-any 512K (id 4) Match access-group name DAGExtended IP access list DAG 10 permit ip host host time-range DAG-REP (active) (22793 matches) 20 permit ip host host time-range DAG-REP (active) (14156 matches)The service policy is applied on the input side of the 2 interfaces on which our devices are connected.As you can see, the access list identifies the interesting traffic as traffic from two specific hosts to one specific host. The problem we are having is that bandwidth is also being throttled between the two source hosts even though it is not defined to do so.What can I do to limit traffic from the two source devices to the single destination device without limiting bandwidth between the two source devices?

Cisco Switching/Routing :: Not Capturing Span Traffic On WS-4510 / SupervisorV / 12.2(54)SG1

Mar 22, 2012

I have configured Span port on our 4510. We have an application 5view server to monitor trafic connected to G9/17 Since we have changed the network connection from physical Giga port and add a Port-channel instead, we don't see any more trafic from the new Port-channel to G9/17
We have the configuration below on our 4510 :
monitor session 1 source interface Gi4/6
monitor session 1 source interface Po20
monitor session 1 filter vlan 311 - 312 , 375
monitor session 1 destination interface Gi9/17
From the commands show, we don't see the trafic duplication from the source to the destination port :
Port Source
4510-5567#sh int po20
Port-channel20 is up, line protocol is up (connected)
Hardware is EtherChannel, address is 0016.9de2.a818 (bia 0016.9de2.a818)

Cisco Security :: Catalyst 4510 / Switch Port In Dot1x Multi-auth Mode Stops Passing Traffic?

May 6, 2010

I am experiencing a problem on a Catalyst 4510 (cat4500-ipbasek9-mz.122-53.SG.bin) with 802.1x configured. Client PCs are connected via a mini desktop switch to a Cat 4510 switched port in multi-auth mode. The configuration of the port follows:
!interface GigabitEthernet2/34 switchport mode access ip arp inspection limit rate 30 authentication host-mode multi-auth authentication port-control auto authentication periodic authentication timer reauthenticate server dot1x pae authenticator dot1x timeout tx-period 5 dot1x max-reauth-req 6 spanning-tree portfast ip verify source vlan dhcp-snoopingend
It happens from time to time that the Cat 4510 port stops passing traffic. Reconnecting the mini switch recovers the communication. Client PCs connected to the mini switch seem to be authorized at the moment when the problem occures. The RADIUS Termination-Action attribute is set to RADIUS-Request. The problem is not present if "authentication periodic" is disabled.

Cisco Switching/Routing :: 3825 ISR - Traffic Route From Switch Port To Router Port

Jun 5, 2013

I'm fairly new to Cisco products am in the process of developing my network knowledge on a deeper level.  I have a 3825 with a HWIC-4ESW and I'm struggling to fully understand how the two "see" each other.  I've setup a V LAN with a layer 3 address on the HWIC and added the switch ports to it.  This seemed to allow devices connected to the switch ports to talk to the built-in router ports.  I thought this was all making sense until i applied an access-list to the router port.  It's a simple ACL i'm just using for testing and the only thing it does is blocks telnet from anywhere.  I know the ACL is setup properly because if I connect a device directly to the router port i cannot telnet to the port.  However, if i connect a device to one of the switch ports, i am able to telnet to the router port successfully. 

It seems that I'm missing something with how traffic flows from the switch port to the router ports and how the two "see" each other.

Cisco Switching/Routing :: 3560 - What Happens When Voice Vlan Command Is Added To Trunk Port

Oct 11, 2010

Any way to test in a lab what would happen if a tech mistakingly added "switchport voice vlan XX" to a trunk port? I am try to do some RCA on an issue and this has been identified as a possible cause by one of my techs.
The config is Switch1------Switch2--------Switch3 Each interswitch connection is configured as a dot1q trunk with all vlans allowed. The link between switch2 and 3 is where switchport voice vlan 10 was added. Switch1 is a 3750 and 2/3 are 3560's.

Cisco Switching/Routing :: 3560 Command Shows Two Devices Connected Through Same Local Port?

Oct 14, 2012

show cdp neighbors command shows two devices connected through the same local port?I have a Cisco 3560 that when I issue the "show cdp neighbors" command I get the following results: [code]
the question is why is this showing that Gig0/3 is being used twice to  connect to two different devices.  I have verified there is no hub  connected to this port and in fact Switch3 is not connected to Switch1  at all yet it still shows up in the CDP table.
I have cleared the CDP table on every device at this location and still get the same results.

Cisco Switching/Routing :: Switch Port Auto-state Exclude Command Not Working In 4500

Cisco Switching/Routing :: VTP Traffic Not Seen On SPAN Port On 3750

Dec 12, 2011

Been dealing with a strange problem for several days now.  It started out with a problem that I thought was VTP related but ended up being something else.  I setup a span port on a 3750 that I am connected to that was mirroring the trunk connection coming into the switch.
Never saw an VTP traffic come across the connection but doing a sh vtp status indicated the traffic was arriving and getting processed.  When I found some debug commands (debug sw-lan vtp), I was also able to see the packets go between switches.  Seeing this issue concerns me that there is other traffic that isnt showing up during a span session.
I know that doing a span on a switch, especially using a trunk port as a source, isnt a good idea.  Since I didnt have a TAP at time, this was my only choice.  I have since borrowed a NetOptics TP-CU3 tap from a good friend and was able to confirm the VTP traffic was going across the trunk connection between switches.
All of my 3750's are running 12.2.55.SE.

Cisco Switching/Routing :: ASA 5505 Dropping Port 443 Traffic?

May 10, 2012

Networking is not my gig, but it has to be at this very moment.  We have an ASA 5505. Let me explain what's going on.
On Tuesday I wanted to be able to use the ASDM since there is less room for error.  But we only had a console set up.  So I ran the following commands...
in ($config)   
http      of course didn't do anything incomplete command
http        didn't anything incomplete command
http inside 


Everything started working after that.  Everything worked fine all of wednesday and thursday.  Then this morning it stopped processing again.  When I traceroute it gets to the machine that is hooked up to the console and stops.  So I'm guessing its actually getting to the ASA router and being swallowed up again...

Cisco Switching/Routing :: QOS Between 4510 And 3550?

Oct 31, 2011

I am having issues working on my QOS between 4510 and 3550 switch connecting on layer 3 through a service provider. I have class maps and policy map setup on both sides and then policy map attached to interfaces however i dont see any traffic matching in policy map on 3550 switch, i do see some traffic matching on 4510 but the speed with which its increasing has my doubts about it. When i make voip calls ( VOIP switches are sitting behind 3550 and are mainly 3550 pwr 24 port switches with phone ports configured for auto qos voip cisco-phone and trusting cos) i rarely see the RTP matching in class under policy map.

Cisco Switching/Routing :: IOS Upgrade On 4510

I am currently running 12.2 (53) and am looking to move up to the 15+ train. Are there any pre-reqs prior to the upgrade that any one is aware of?Unfortunately I have no "lab environment" to test it in. I have production switches with minimal impact to the campus and if done late night I could have it restored back before open of business the following morning. My FW is up to the latest version and I have found nothing in the release notes specifically stating that there would require any stepped upgrades up to v15 and higher.

Cisco Switching/Routing :: 3750 - How To Isolate Fiber Port Traffic

Jun 18, 2012

We would like to setup a link to our DR site that is separate from our main network traffic.  This link will be used by an EMC VNX SAN for replication traffic.  The SAN will be plugged into a fiber port on a 3750 switch and going out from the same switch (going in as multimode, going out as single mode) into a patch panel that runs over to the DR site (about a mile away).  At the DR site it will go from the fiber panel into another 3750 switch which ends up going back out of that switch into our DR SAN.
I'm wondering what the best way would be to configure the fiber ports to accomplish this.  I'm affraid that the replication traffic will find it's way over through another route and congest our main network unless configured appropriately.

Cisco Switching/Routing :: 4510 PoE Switches Keep Failing

Jun 11, 2013

We have an issue where switches are failing weekly in a switch closet.  In the past month we have gone through several 3750G switches and a couple 4510s.  The power supplies have eventually made a popping noise and had to be replaced.  on the 4510s we've tried two chassis and gone through several power supplies.The switches have been behind UPS systems so should be receiving conditioned power.Could load from the PoE devices really be causing this?  I wouldn't think it's power since they are behind a UPS.

Cisco Switching/Routing :: Unexpected Traffic On Nexus 5000 Trunk Port?

Feb 6, 2013

So I took a laptop with wireshark and plugged it into a nexus 5000 port that is configured as a trunk with 3 vlans allowed on it. The laptop was seeing all kinds of traffic on the wire, most of it was not involving my laptop.
For example: Server A VLAN 10=  Server B VLAN 20= and wireshark laptop is plugged into a trunk port which is allowing those vlan's. The vlan's are routable. is seeing the entire conversation when backs up even though it has no reason to see it. It is as if the trunk is spanning traffic to the laptop port. No span is setup however. It's really weird. This is not just broadcast traffic, but actual tcp taffic between Server A and B. Why would a trunk port see traffic between 2 other servers talking to each other on the vlan.
Trunk port configuration below:
Interface Ethernet 141/1/3 
switchport mode trunk
switchport trunk allowed vlan 10, 20
