Cisco Switching/Routing :: Catalyst 4506 Count Interface Input / Output Rate Always 0
Jan 20, 2013
Our customer get the problem that the switch count the 5mins input/output rate of connected traffic interface always ZERO.The problem only occur in the module 3,4 and 5 interface, module 2 has no problems.

On my SUP-7E, when I issue a " show interface vlan X " I cannot see the expected input/rate reflecting the real rate (which should be very high).
5 minute input rate 0 bits/sec, 0 packets/sec
5 minute output rate 4000 bits/sec, 2 packets/sec
(Under the physical interfaces it is ok)However on other SUP-IV I can see the real rate.
My questions are :
- Why the SUP-7E does not reflect the rate, whereas the SUP-IV does ?
- I have heard about the 'counter' command under the vlan interface to activate the rate counters. Is this command application has any side effect on the switch ?

I found increasing of total output drops and output queue drops even input rate was low and no qos apply on this interface. I plan to increase hold queue out for output queue.

when i type "show interface" command on 1941 router, shows below print. Why 5 minute input-output rate are 0 bits? Can it be a bug?
5 minute input rate 0 bits/sec, 0 packets/sec
5 minute output rate 0 bits/sec, 0 packets/sec

I have a video feed coming into my 3570. It comes in at 5 minute input rate 18777000 bits/sec, 1695 packets/sec. However, the uplink to the router is much different, 5 minute output rate 130000 bits/sec, 28 packets/sec. I am in a lab and about ready to go into testing phase for a project when we discovered this problem, as this video feed is not veiwable on the other end.
Below is the config and capture from the switch.

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?

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.

We have a Cisco Catalyst 4506 running: "Cisco IOS Software, Catalyst 4000 L3 Switch Software (cat4000-I9K91S-M), Version 12.2(25)EWA14, RELEASE SOFTWARE (fc1)" I have configured the default gateway as: ip default-gateway X.Y.116.65, However, when I do, "show ip route", it only shows the 3 connected networks and states "Gateway of last resort is not set". The Command "ip classless" is not set. I read on some blogs that this might explain the issue. However, when I go into config mode (config t), I get the following output.

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?

We are facing since one month in our two Cisco WS-C3750G-12S on many interfaces input errors when data transer or ping (ICMP) increase input erros. Not only port 1 but many interface has same issue, i have change new IOS but still same issue, once i have erase startup config but same issue we are facing and finaly i have replace same new switch with the same IOS it's working fine.(c3750-ipservicesk9-mz.122-55.SE4.bin) [code]

We're having kind of a problem with our Catalyst 4507r switches. If we do a "show interface" command we're getting a lot of "Total output drops" on some of our interfaces. It seems to be most of the time on the same vlan.I was wondering if it has got something to do with QOS or queue selection As we don't have any QOS markings configured, is it possible that all traffic is using only one of the four tx queue's?

I have too much output drops in my cisco 7206 VxR NPE G1 router. I'm doing dot1Q on this interface and is connected to switch , i changed the router and IOS but still the error is same . What can be the reason . The interface on switch and router are 1000/Full and i changed the cable also . The traffic only comes about max70Mbps and it is really confusing. [code]

How (and is) it possible to rate limit pps on an interface (physical/logical), on a 6509-E?The porpuse is to protect from attacks which lead to very high pps, bypassing traffic rate-limits, and effecting the device's performance

I have 2 Cat-6506's that are used for my WiSM's. The only thing in both Chassis is 2 X WiSMs a SUP-7203A and a 6516A line card.The only connection between the rest of the network and these chassis is on port gig 1/2.[code] If I have read other posts correctly all points to the ASIC being overun by that traffic being sent from my WiSMs out to the Network.

I have a really weired thing happening on 6509 device with one of my customers.The device has a SUP 2 (MSFC2) with version 12.2.18SXF17B.
any VLAN interface once administratively down or simply down shows on "show interface status" output as VLAN.While it supposed to show "Routed". However once the port is up it is shows "routed" like it should.

I have 1x Cisco 6509 with Sup2 and MSFC2 and it is running on IOS (c6k222-jk9sv-mz.122-17d.SXB11). I have following policy map :
Policy Map VOIP
Class IP PHONE
priority percent 75
and the following command on each interface: service-policy output VOIP those configuration are working fine on SUP2 with MSFC2 but last week I tried to upgrade the SUP2 to SUP32 on the switch and upgrade the IOS to the latest version (s3223-adventerprisek9-mz.122-33.SXJ4) but when I try to put service-policy output VOIP on each physical interface I am getting the following error:
"Priority command is not supported in output direction for this interface" and when I try to add service-policy output VOIP on a V LAN interface I am getting following error:
MQC features are not supported in output direction for this interface. Will I need to change something after upgrading to SUP32..

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.

I am getting alarms on Solarwind indicating interface down on "GigabitEthernet 4/7 - Gi4/d1" and "GigabitEthernet 4/8 - Gi4/d2" from our core switch 6509.Remote login to the switch does not show the interfaces when I do the "sh run" command. Now I am at site trying to identify and diagnose this fault.Looking at the numbering on the switch, it indicates to me the card where these alarms come from is from the 'intrusion dectection module'
how I may login and identify this interfaces and rectify these alarms.

At one of my sites, I have a 100mbit TLS. For this connection to work properly, the port on my end needs to be setup for 100mbit, full duplex. When I connect the TLS to an interface on my Cisco 2821, configured at 100/full, it works perfectly. Now the confusing part, I'm trying to connect the TLS to a Catalyst 2960. I configure the necessary port for 100/full, and get 'notconnect' on that interface. I set the interface to auto/auto, and it negotiates at 100/half and causes collisions and packet loss.
