[code] Can't find any wrong with the switch ports and AP's that can result in Duplex mismatch.The only difference I can find is the AP that is in all duplex missm. log's is used for other Mesh AP's to connect to.

View 1 Replies View RelatedIn 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
I 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

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.
I am doing an small project, I have to connect 4 cisco switches SF 302-08 (1 GBIC each one) to a core switch SGE 2000 (4 GBICs). Because of cable length I have go connect all 5 switches with fiber. The fiber termination is multimode LC duplex. My confusion is on the mini GBICs. There is compatibilities issues i been reading. [code]

We are facing to an annoying issue. We have a 6509 running in Catos 8.3(4) with WS-X6548-GE-TX, WS-X6348-RJ-45 and WS-X6148-RJ-45. When we configure the mode in auto negotiation, it comes up in half duplex. We need to configure the speed mode at 100Mbit/Full to make it work. But if the chassis or port restarts (not the server), the link becomes half duplex. This happens only on module in Gigabyte like WS-X6548-GE-TX.
Cable have been replaced but does not work. It is not happened on another chassis running on IOS 12.2(18)SXF17b with WS-X6548-GE-TX.
Client has a building that is located 300Ft apart and would like to provide IP communications for 3-4 IP hadsets back to an IP PBX. They do not want to dig up the parking lot so we proposed using a wireless bridge. I noticed that Cisco discontinue the 1300 and 1400 Wireless Bridge. Can I use a 1262 with external antenna in Workgroup Bridge mode to perform this functions? I will put a Layer 3 switch on both ends to route traffic (3560C-8). Should I use the Yagi antenna's for outdoor use?
View 1 Replies View Relateda customer got an 1552 outdoor AP in local mode and installed it at a building. It has to run as a Mesh AP (MAP). Now the AP connects one time to the WLC 5508 and started a download. After that, the AP never came back. Like we saw on the other installed 1552 RAP's, they all where in local mode.We configured all AP's to bridge mode, but the MAP could not join anymore.Is there a CLI command to change the mode on the AP itself?From the WLC it's not a problem, but for the AP CLI I cannot find sth.

I haven't been very impressed with them - I have to reboot them at least once a week and figure it's a roaming issue. Since they are a residential product they probably weren't designed to do a lot of roaming.I started playing around with WGB and setup an 1142 AP and got it to work. Unfortunately, the only place I can put the AP is inside the cart and the metal top seems to be interfering with the wireless signal.
View 1 Replies View RelatedI'm trying to get confirmation on whether you can have workgroup bridge mode on the 1040 series model.
The 1041N has the same IOS as the 1141/1241 and it has the settings are there, but I read somewhere on the cisco site that workgroup bridge is only supported on 1100 and 1200 series, is this correct or old information?
Scenario is: I have an existing stand alone 1041N AP, on the other side of the building I have a network LAN switch with a couple of PCs, instead of running cables I would like to add an AP as a bridge to link that switch and PCs to the network that the AP is plugged in to. I believe this is called Workgroup Bridge Mode. In fact there already is a cheap non-cisco wireless device doing this but it is unreliable.
I just placed an order for Two 1041N APs, do I need to change the order to Two 1141N instead?
Also even if the 1041N does not support workgroup bridge mode, can it still act as the ROOT Bridge and have 2 1141N APs configured in bridge mode connected to the 1041N?
I have a WLC2504 and 2 LAP1261N (converted from autonomous to lightweight) with release 7.0.116.0 and I want to create a point-to-point mesh link between the 2 APs. When trying to change the APs mode from local to bridge I receive the message "This AP does not support bridge mode" even if the release notes say that mesh is supported on AP1261N. I tried to change the mode from gui and also from CLI.

View 1 Replies View RelatedI am configuring a mobile van that is used for a mobile health clinic to drive to several locations and when pulling into an allocated parking spot the van will connect via wireless automatically. I am using autonomous 1252 AP's and am considering either briding or workgroup bridging.
The issue I am encountering is that the AP inside a van is a router that has to do DHCP across the wireless and because the ethernet interface between router and AP in the van never goes down the router does not know to re-DHCP. I remember from way back there was an IOS command to track a serial interface and drop the ethernet if the serial link goes down. Is there an equivalent command for AP's to drop the ethernet interface if the radio interfaces go down?
I'm using the 2106 in one environment with ROOT AP and MESH AP and when i put these in the Bridge mode, when one client connects to them it isn't working well, sometimes i can reach the client and sometimes not.
I tried it with an Access Point that connect with the ROOT AP or MESH AP and will do an ethernet bridging with another wired client (camera), what happens is very strange because sometimes i can reach the bridge client and sometimes i can reach the Access Point that is doing the bridge. I can't access the two clients at the same time. In this situation i lose the images from camera when i have access to the Access Point and when i get the images from camera i lost access with the Access Point.
When i put the ROOT AP in the H-REAP mode Local Switching with AP 1142 or AP1552, the clients connects well and the bridge mode in the another access point works without problem, when i put the H-REAP in Central Switching i have the same problem.
I'm using in the 2106 WLC the version 7.0.240.0.
I try to change the AP mode of my LWAPP 1242 from local to bridge mode. But when the AP reboots it never associates with the controller, i have to reset it manually.I have the same issue with a LWAPP 1142.I tried to modify the AP mode configuration through the controller CLI but it's the same behaviour, AP never associates.Is there any particular parameter or configuration to perform before changing AP mode?

View 11 Replies View RelatedI have just been escalated to Level 3 support about my bridging issues.Bridge / Repeater mode configuration separated by 150 feet. Worked perfect for over 3 months.Upgraded firmware due to lockups starting to happen, now cant get the bridge / repeater to work longer than 15 min.After MANY support calls, new devices sent (version 2's) still no luck.
Talked to Marcelo at1 866 606 1866 and he stated that the Bridge / Repeater mode will not be supported farther than 50 Feet.(seems like a cop out to me) He didn't seem to have an answer as to why it worked for 3 Months other than interference Of which I have ran spectrum analyzers and see no Interference. **** even 10 feet away I cant get the units to work longer than 15 min.So I definitely think the 50 foot thing is a BS answer.
Also they have told me that External Antennas are not supported with these devices.Again even though People 500 feet away connect just perfect (without a bridge / repeater mode) with 50% coverage!
so here I am (spent 600 bucks) on bricks.. and nobody will support the device and I cant seem to get my money back.I have 8 customers with these devices, I am not going to use Cisco any longer. However will continue to fight this,as we all seem to have the same BS issues.

One thing I can see - if I run a ping to the last IP.. every now and again I get a single response then it drops again. Via the console on the access point I can see it's getting to the controller, getting its name then reading something that caught my eye

I have been using WAP4401N for almost a year in our office and I’m very happy of this device, never had any problem. So I bought 3 new ones for our customer which supposed to work in configuration below:
Network ----- AP1 –Bridge mode ----- AP2 – Bridge mode -----AP3 – Access Point mode.
Everything was working perfectly fine to the moment than bridge was broken. I can get access to all AP (obviously when connected to proper part of network) however not able to ping from AP2 -> AP1 or opposite so basically no link between AP1 and AP2. After reboot everything is working fine to next time (happens twice in two days). When I go to System Performance can see Connection is enabled but doesn’t work.
I upgraded firmware to latest version (2.0.5.3) but haven’t worked. When I’ve done some research found many users having similar problem with this device and basically they recommend to don’t buy. Unfortunately this is not an option for me as I’ve already purchased them.

I bought the EA3500 nine months ago mainly for the USB port (for a NAS). I recently replaced Comcast Cable with Verizon FIOS. So I now have the FIOS router as my main router (its' IP address is 192.168.1.1). I put the EA3500 in bridge mode to extend the (wired) network. I could get: After going in to bridge mode (with DHCP), I can not log in to the EA3500 (IP address 192.168.1.5 assigned by the FIOS router). I connect my computer directly to one of the EA3500 numbered ports (after various combinations of rebooting EA3500 and rebooting PC). It just continues to say "waiting" and never logs in. Tried choosing a static route (tried both 192.168.1.43 and 192.168.1.5 with 255.255.255.0, gateway and DNS1 = 192.168.1.1) with no luck.Since I can't log in, I cannot set up my NAS on the USB port of the EA3500 (so I haven't gotten far enough to determine if the USB port will even work in bridge mode).Thought about ensuring the latest firmware but since I can't log in I can't do that. (And after a hard reset EA3500 IP address is 192.168.1.1 which creates conflict with FIOS)
View 9 Replies View RelatedAs I understand, the latest FW for the E4200 makes it possible to put he router into bridge mode. In this mode, I can use it as an access point. In bridge mode, should I then connect my router to the WAN port at the E4200?The other way to make the E4200 into an AP, is to disable DHCP and NAT and give the E4200 an IP address out of range for the DHCP range in my preferred router.
Choosing between this two option to make the E4200 into an AP, which is considered to be the best solution?And to be sure; using this option, then the Ethernet cable should be connected to the LAN port of the E4200? is the performance of an E4200 in AP mode the same as a dedicated AP like the WAP610N?
If I turn off the wireless on my DAP-1522 in bridge mode, will it basically become a Gig Switch?? I've changed my network around abit and don't need it in bridge mode at this point but would love to use it as a plain switch. Would this do the trick??
