Cisco :: WS-C3560-48TS Network Assistant / Unable To Add A Switch
Oct 21, 2012
I have a network running some 20 switches, two controllers and many AP's. All the devices that should be able to connect to cisco network assistant can successfully. However there is one switch that will show in neighbours but will give the message of “unable to connect to device” when I try and add it to the topology.
As far as I can see the config is identically to all other similar switches in the network. I can telnet from a switch (management VLAN) to the switch in question. However when I try to ping or telnet from the PC running network assistant (different subnet) I am unsuccessful. However I can ping/telnet to all other cisco device from this PC. The switch is a WS-C3560-48TS and I have included the config for firstly the switch in question and another switch of the same model and config that works correctly.

I have below switch and I was interested in configuring GRE on one of the interface. So I tried to create tunnel interface, the tab completes the command. Is GRE supported on this switch and IOS?

I have a strange problem with one switch in my LMS 3.2.1 installation.It is a WS-C3560-48TS with IOS 12.2(50)SE3 running. I have nine switches with the same type and IOS running without problems.
I notice the problem because there were no UT data for that switch. In RME and CS it was managed.Checking SNMP and config of the switch, but can't find any issues.Because at this time LMS ran in version 3.2 I installed at first CM 5.2.1 and after that the patches for CSCtd49439 and CSCtg20882.Next step was RME 4.3.1 with a lot of patches for different issues. Then I installed the patch for the internal error of CS (CSCtd07131).And finally I installed LMS 3.2.1 and patch for CSCto46927.Last step was installing the latest device packages. I did this directly from the application because it is much better handling than do a manual download. No the system seems to be fully updated.
I had the hope that CM will now find and manage this one switch. But it is still not available.I can't find the device in the data collection. But I can find it in the "Include Devices From DCR", although I configured to fetch all devices from DCR automatically to CM. To manually include the device is not working, too.
P.S. I used that step-by-step update path because it worked on two other servers very well for me.

I have two WS-C2950G-24-EI switches each of which were running software version 12.1(22)EA2-C2950-I6Q4L2-M. Both swtiches were viewable from Network Assistant version 5.6(3) and part of a community. I then updated the software on one of the switches to 12.1(22)EA14, and now Network Assistant will not add the new updated device to the community and gives an error of "WS-C2950G-24-EI is not supported as community member". Is the latest version (12.1(22)EA14) not supported by Network Assistant? The release notes indicate the Minimum Software Release is 12.1(22)EA4.

We have a Cisco switch in each office and every now and then the port that has the D-Link Wireless AP (DAP-1522) connected to it goes to err-disable state. Actually sometimes even a regular port that has a cisco phone connected may also go to err-disable state (less often). So I have to telnet into the switch and issue shut and no shut command on that interface to get it back to life, then it works for a few days or weeks until it happens again. Any suitable configuraiton for that interface, that would prevent that from happening or a workaround ?
Here's the info:
Model: cisco WS-C3560-24PS and cisco WS-C3560-48PS
Image:c3560-ipbase-mz.122-35.SE5.bin
This is the log from one switch:
31w5d: %PM-4-ERR_DISABLE: psecure-violation error detected on Fa0/2, putting Fa0/2 in err-disable state
31w5d: %PORT_SECURITY-2-PSECURE_VIOLATION: Security violation occurred, caused by MAC address 74e2.f592.f7f2 on port FastEthernet0/2.
31w5d: %LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet0/2, changed state to down
And from another, which is almost the same:
5d10h: %PM-4-ERR_DISABLE: psecure-violation error detected on Fa0/3, putting Fa0/3 in err-disable state
5d10h: %PORT_SECURITY-2-PSECURE_VIOLATION: Security violation occurred, caused by MAC address d8a2.5e31.2cf6 on port FastEthernet0/3.
5d10h: %LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet0/3, changed state to down
5d10h: %LINK-3-UPDOWN: Interface FastEthernet0/3, changed state to down
Here's the configuration of fe interfaces (they are all alike):
interface FastEthernet0/2
description Voice & Data Combo Port
switchport access vlan 11
switchport mode access
switchport voice vlan 15

I'm experiencing considerable difficulties with CNA and my 4948E cat's. Front panel view, vLans and VTP utterly fail...and I have gone to GREAT lengths. I initially configured them all for comprehensive use in a vSphere environment. Storage switch fabric and multi-vlan guest networking. I wiped the config's across the board, factory reset all of them in an attampt to get CNA working. NO GO and it's been wildly frustrating, 80+ hrs spent with no results.
So is CNA truely compatible with the 4948e? And if so, WHAT IN THE **** AM I DOING WRONG!!?!?!?!!!!!?

CNA 5.8(1)
32 devices
When I first launch the application, it promots for CCO login information, but then tells me the username or password is invalid. I reset it once, and it appeared to work. Next time I launched the application though, it gave me the same login error and did not store any of the device credentials. This is a new install of CNA and it just has one community setup on it now. I've tried 2 different CCO accounts and they both give the same login failure. I know the passwords I'm using are correct though.

Since I updated a Catalyst 2960 switch to IOS version 12.2(55)SE1 I can't do searchs by MAC address, when I do "Monitor->Search" the following error appears:"The software version of the selected switch does not support some of the CLI commands in read-only mode for this window. You must have read-write access to this switch to display complete information in this window" If packets are captured you can see that the issued command by the CNA host is "GET /exec/show/mac-address-table/", the answer from the switch is:"show mac-address-table ^% Invalid input detected at '^' marker.
If I do "Configure->Switching->MAC Address" instead I get the mac address-table correctly. In this case the issued command is "GET /exec/show/mac/address-table/dynamic" and no error is displayed, the answer from the switch is the list of mac-address table.

With my brand new Cisco 3850 Switch, I got it configured with a LAN IP. Then, on my PC I opened up Cisco Network Assistant (version 5.8.5.1 which supports the 3850). I went to add the 3850 to the community by discovering the device, and was prompted with the user/pass box. The password I set was not allowing me to connect, and I realized it's because a username was required and I had not set up a username on the switch. So, I then configured an admin user with level 15 privileges on the switch. However, now when in CNA I try to add the 3850 to the community, it doesn't even prompt me for user/pass, it just says "unable to connect".
What do I need to do to add this 3850 to my community?

I have a Cisco 2948G switch that I am trying to communicate to through this program. It has both an IP address and is hooked up through a cable. I can get Cisco Network Assistant to come up and ask for it's Username and Password, and that it is where I am stuck! I have no clue as to what to put in there as a username and password? I do have a password setup on the switch to login in to it during terminal mode, but that is it.

Does the latest version of the Network Assistant support the AP1131AG / AP1131G model?
From the "supported device list" documentation it seems yes, but I've tried to import them into the map and received the message indicating that is not supported as a device...AP1242AG/1242G are not having this problem.

I am trying to connect my Cisco 2911 router to my community in CNA. I can see the routers on the topology map, but when I try to add to community I get an error message stating that the router is unreachable (Unable to connect). I can ping device from ame client. I can view Device Properties for map (Device type: CISCO2911/K9). Telenet attempt to connect but we only use SSH for connectivity (the same as all of my switches that are connected to community). 2911 is listed as a supported router on Cisco site.

why Windows Server 2008 is not a supported OS for Cisco Network Assistant?I am currently evaluating switch management solutions for use with Catalyst 2960 and 3750 series switches, and would like to be able to backup and restore configurations, as well as make configuration changes. My management Server is running Server 2008.Is Prime LMS my only option?

Had a switch die over the weekend, a c3560, per our normal procedure I pulled the hardware put a very basic config on it(vlans, portchannel, uplink ports, ip of management vlan, con and vty security, snmp, enable secret, and hostname). Then I use solarwinds orion to upload a copy of the old config to bring the switch back to the same state as the one that failed. Its a system that has worked for us 3 or 4 times in the past. But this time when the base config was on the box it couldnt ping across the network.I have tried clearing the arp cache and the dynamic mac tables, i verified the routing tables and even removed the 10.1.185.128/27 route and re-added it, saw the routing update go across to the other 65k, tried bouncing the edge switch(i cant bounce the 65k's), took down the po between the edge and 65k.

Looking to setup a backup router for our disaster recovery plan. We currently have a Cisco 877W that was setup by our ISP. I can log into the device with Telnet and a console cable, but I am not good using IOS commands, so I would like to use CCA. Unfortunatley, I cannot access the router using the software. I assume something is disabled in the config. Like HTTP or something.

Any replacement fan for the WS-C3750G-48TS-S switch that runs quieter than the one originally built into this router? I've searched a number of web sites and found plenty of replacement fans available but none of them show noise level specifications.
particular manufacturer/model combination that works in this router that will drop the noise level down while maintaining air flow. This switch is in a short network rack in an small office that also includes people. The current noise level isn't defining like some servers, but is loud enough to be distracting.

We have an aging 2611 router that that we need to replace due to the fact that its 10Mb/s Ethernet ports are limiting our internet connectivity throughput (we have a 20Mb/s circuit).
The purpose of the 2611 router was to route traffic from multiple devices connected to a 2950 switch's VLAN X to the internet. Can we achieve this same functionality with only a 3750C-48TS-S switch? Could a static route statement on the 3750 replace the need for the router?

I have a stack composed by:
Switch Ports Model SW Version SW Image------ ----- ----- ---------- ----------* 1 52 WS-C3750G-48TS 12.2(35)SE5 C3750-IPBASE-M 2 52 WS-C3750-48TS 12.2(35)SE5 C3750-IPBASE-M
All works well, except for the client connected to the gigaethernet ports that do not works at 1000, I am sure that the clients are able to do it. I have done a check on one of 48 port:
SW3750_100_ced_rk0#sh int gigabitEthernet 1/0/24 capabilitiesGigabitEthernet1/0/24 Model: WS-C3750G-48TS Type: 10/100/1000BaseTX Speed: 10,100,1000,auto Duplex: half,full,auto Trunk encap. type: 802.1Q,ISL Trunk mode: on,off,desirable,nonegotiate Channel: yes Broadcast suppression: percentage(0-100) Flowcontrol: rx-(off,on,desired),tx-(none) Fast Start: yes QoS scheduling: rx-(not configurable on per port basis),tx-(4q2t) CoS rewrite: yes ToS rewrite: yes UDLD: yes Inline power: no SPAN: source/destination PortSecure: yes Dot1x: yes
Seems all ok but if I try to disable auto config about speed and duplex, and force it manually to 1000 full, I lost the client when i done it I forced the speed and the duplex to 1000 full on the client too.
