In LMS I have a 6513 with several sx 1000 interface setup for etherchannel to catalyst 3750
both sides are set for autoduplex but LMS reports that there is a link duplex mismatch. We just installed the latest patches for the LMS 4.0.1
Seen Duplex MisMatch errors on a N7k with a LAG going to the 5508 WLC? WLC code is 7.0.203.0. I found a BUG that is private to Cisco ( CSCth11041 ) that looks like it, but I want to make sure.

View 8 Replies View RelatedI cannot seem to correct a duplex mismatch issue.I have a Cisco 2950 switch connected to a Cisco 2621 router. I am running a per-interface Vlan. I have two fastethernet ports and one NM-1E card installed on the router. One fastethernet port is connected to my gateway router, the second fastethernet port is connected to my switch for one Vlan. The NM-1E Ethernet card is being used for the second Vlan which consists of nine IP cameras. Though the cameras on the Vlan are working fine.Now, the NM-1E card is set to half-duplex. I know that I should be using a fastethernet module like a 1FE 2W or a 2FE 2W card, (which I have,) but the router does not recogonize either one of these cards when they are installed, and yes, they have been confirmed as good cards.
Using Router-on-a-Stick configuration is out due to the bandwidth contention besides the fact that the router I am using it on will not handle this due to the flash being an older version.I have forced the switchport to half duplex, setting the speed to 10. I was getting fewer error messages at first, but they soon increased back to the frequency that they began with.I have set the switchport to duplex auto, but this failed to resolve the issue.Obviously, I cannot force the switchport into duplex full since the NM-1E interface is set to half duplex. Can the NM-1E card be configured to full duplex? I can't seem to find any documentation showing where it can be forced to full duplex mode.Could nine IP cameras just be too much for both the router and switch to handle?
I have a 4503 switch (in L2 mode) running 12.1 hooked into a C2950 running 12.1, using regular 4 pair Cat5e cables to connect between them. The 4503 has Gigabit port 2/1 trunking to the 2950's Fa port 0/13.
When I set the duplex mode to DUPLEX FULL and SPEED to SPEED 100 on both switches (for their trunk ports) the link fails, and my 4503 loses connectivity (since it gets it from the 2950).
Here is my config from the switches (per description):
The 4503:
interface GigabitEthernet2/1
switchport trunk encapsulation dot1q
switchport trunk allowed vlan 1,2,100-140
[Code].....
Note, this is the only mode that works (which seems to work fine, but I get TERRIBLE throughput for anything that goes over the 2950.
1 week ago, I got a call from a client that reported a network outage, the client told me that, 3 switch has crashed he try to console but it just hang. I ask him, did you change something? he said he didn't change anything, he just pluged a nortelswitch to the cisco switch number 9, but that switch doesn't crash like the others (3,4,8). I check the uptime, and yes the switch never been powered off..
the topology look like this
____ 6500 ____
/ / |
1 2 3 4 5 ...... 9
the vlan is end to end vlan, so vlan span between all those switches. transparant. this is collapsed topology, core and distribution is the 6500 itself all of the 1-9 access switch are in the same rack, with no loopguard, and bpdu guard configured. and connected to the core using etherchannel. the problem is there is no log available to start the troubleshooting/investigation.
I have the following issue; I am getting a duplex mismatch between a Cisco 2960 TT-L Switch running IOS 12.2(35) LAN Base Image (Gig0/1) and a Cisco 6506 Switch running IOS 12.2(33)SXH Adv IP Services (Gig2/19).
I have tried several combinations of the duplex/speed settings on both sides but the only that works is setting duplex/speed AUTO on the Cisco 2960 which ends up autonegotiating to HALF duplex and 100Mbps.
If set the LAN to 1000 duplex I get better throughput than If I set it to Auto 100/1000,but the problem is that then my internet modem stops working,is there a solution to this ?
View 11 Replies View Relatedwe have a chassis 6513-E and a module WS-X6748-GE-TX, I'd like to know if could I put this module in any slot, since the documentation from Cisco says that any slot from a chassis 6500-E Series can support this module. And then in the documentation of WS-X6748-GE-TX says that this module is not compatible in the slots 1-8 of the 6513 chassis, only from 9th to 13th slots, in those slots from the 6513-E we already have 4x WS-X6748-GE-TX, and we'd like to know if could we put the module in the rest of the slots. The 6513, and 6513-E is kind of confusing.
View 4 Replies View RelatedI have a broadband connection and recently I bought a new D-Link wireless router for accessing internet on my Android phone via Wi-Fi. Router model no. is N 150 DIR-524.After configuring it was working fine for a week or so and then one fine day internet stopped working on my PC and router LED for internet was not glowing as well. So I called my ISP and they changed my ethernet card settings (nVidia).They changed the 'Speed/duplex settings' from 'Auto Negotiation' to '10 Mb Half Duplex' and then the internet started working. During this they had disconnected my router. Once they were gone, I reset the router and connected it back. Since then it ain't working Internet works fine when the cable is plugged directly in the ethernet card but doesn't work when plugged via router. Router does everything right from opening the '192.168.0.1' page to saving the settings. But there's no internet access.

When i'm trying to connect using stand-alone Anyconnect (not through the web), I got the SSL error message "The certificate you are viewing does not match the name of the site you are trying to view" (attached).
The certificate I installed for the SSL connection on outside interface got Subject CN=testvpn.mydomain and Subject Alternative Name (SAN) --> DNS Name = testvpn.mydomain
It seems to me that instead of connecting to testvpn.mydomain, anyconnect try to connect to the its IP address. I did try to remove the IP address in Server List in the profile, but it still doesn't work.
If I'm using Clientless (through browser), I don't received this error which means the certificates installed correctly.
Is that a bug on anyconnect 2.5.2019 or is there other ways to force anyconnect to check name instead of the IP against the certficate?

View 5 Replies View RelatedIt is possible to detect situation when two neigbour routers involved in EIGRP routing are configured by mistake with different AS number ?I tried this situation practically. Two routers are connected together via Serial link network. One router has AS 1, other AS 10. I try to detect AS mismatch. First I check what EIGRP packet are comming debug ip packet detail show source <my neighbour IP address> destination 224.0.0.10 Ip protocol type 88. These packets are EIGRP Hello packet.
I try to go more deeply into details.debug eigrp packetsI see only ongoing EIGRP Hello packets. But I don't see any incoming packet from my neighbour (which has different AS number). It seems, because of different AS number router silently drop eigrp packet.Other debug eigrp command also doesn't show any info about AS difference.

I have a 7604 Edge router that connects to our Data centre via Fiber.
but i keep getting input errors on the interface Gi3/5. i also found out that i cannot change the duplex settings on the edge router to auto, i only have two options of full and half and changing it has not worked either.
I have tried to use a switch in between the fiber modem and the edge router to try to manipulate the duplex settings, but when i tried it the port simply shutdown and then i have to reverse the configuration.
The software version of the router is 12.2(33)SRE3, i really need to sort this out as connection to and from the Data centre is quite slow.
I have the following configurations for switch to switch connectivety. sh int sh config int

We have some legacy Cisco 6513 switches with the backbone (16-port GBIC blade) MTU set to 1500. It has a WS-X6148A-GE-TX blade as well, MTU set to 9K.
Now we have a customer sending MTU of 1546, their copper interface terminating on WS-6148A keeps flapping. Does the flapping have something to do with the backbone set to 1500? We cant set the backbone to 9K at this moment since it may be intrusive (reuire a reboot).
I have a tunnel between a PIX 515E version 7.2(2)and a Cisco 3800 version 12.3(11r). There is a mismatch somewere in the configs but I cannot find it. I have included the configs and the syslog errors.

When performing an audit from NCS Prime 1.3 on our 5508 controllers (500 lic) we are getting mismatch messages from many of our 3602i AP's that say the following...
(Type)Configuration Name Audit Status Attribute Prime Infrastructure Value Controller Value
(AP APname, Interface) 802.11a/n Mismatch Spectrum Intelligence true false
These AP's are not configured as Spectrum Intelligence on the controllers, rather as local. It seems that NCS believes that they are supposed to be SI. We have refreshed the config from controller many times but this does not change. The 5508's run v.7.2.111.3 Is there a change I can make on NCS or otherwise to make this mismatch go away? Is this a bug? It is not causing any problems (that we can see) but as most would rather not have these mismatches.

View 9 Replies View RelatedSo I recently got a new computer today and it won't let me use my 100mbps of internet bandwidth. (Asus Sabertooth Z77 with an Intel 82579v gigabit lan controller) I noticed that at the LAN connection properties>Properties>Configure>Link Speed tab the 'Speed and Duplex' option was on Auto Negotiation and it was only accepting (or supporting) the 10mbps Full Duplex. When I switched it to 100mbps Full Duplex it would mark my connection icon with a red cross and when I clicked diagnose it said "Please connect your ethernet cable or your cable might be broken". So I tested my internet speed with that same cable on a different computer (laptop) and it worked with 40Mbps, so I don't think the cable is broken. Also I just recently downloaded some drivers but one was specifically for the Intel LAN controller but I'm a total noob for all of this computer stuff I don't know if it messed it up or something. Is it the motherboard that's not working correctly?
