3524-XL w/GBIC Visual Switch Manager

I have a Cisco 3524-XL switch w/ 12.0(5)XU Enterprise Edition OS
Been using the Java-based Visual Switch Manager to manage it, no problems.
I added a 1000BaseT GBIC, and everything works mechanically and thru telnet, I can manage the switch. Everything works.
But now when I try to use the Visual Switch Manager, I get the following Java Error:
"Visual Switch Manager has detected a change in the devices hardware configuration and needs to redraw the device." I say ok, and it comes back again, and again, etc. The running config has been saved and rebooting does not help. Tried a coupla versions of Java(Sun's). Currently using 1.4.2_07
Any suggestions?

try upgrading the image of the switch, also run the latest Java plug in software. this should help.

Tacacs and visual switch management incompatibility

We have upgraded the IOS on Cisco 2924 switch, configured it for Tacacs, however the visual switch management using Netscape for the above switch doesn't work. Any ideas?

Hi Balaji,
the management port is assigned to a VRF called "mgmt-vrf", so it does not participate in global ip forwarding because it is intended for out-of-band management. This link showes a configuration example for TACACS:

Switch Management

Hey Folks,
There seems to be two schools of thought when it comes to switch management. From what I've read, two different approaches seem to be recommended. The first is to create a switch management VLAN, and trunk it to all the switches. The second is to create a loopback address, and distribute it via a IGP.
Any advantages or disadvantages? Which one do you use and why?
Thanks,
SM

Two approaches are two different kind of design. One is L2 VLAN separated the segment and one is L2 w/ individual NM segment.
What I suggest is to combine both designs that use separated VLAN w/ loopback address that dedicated for the NM traffic. The reason is at L2, it can separated the NM traffic from the production traffic, and for L3, you easily to observe the NM host by different subnet of the loopback address.
However, if there is WAN link that cannot carry VLAN traffic, then you have to use second approach in the WAN link.
And, if it is a L2 switch only, then you have to create a NM VLAN and assoicate the loopback address to this VLAN for NM.
Pease feel free to comment and discuss.
Hope this help.

Changing switch management from default Vlan1

I'm in the process of changing some access layer switches and the distribution switch away from the default Vlan1 for switch management. I'm a little unclear on the native Vlan information. If I change the management vlan to lets say 299 do I need to change the trunk ports to reflect a native vlan of 299?

Not neccessarily. Just make sure you allow the new VLAN on the trunk.

Theming Legacy CDialog and CFileDialog using Visual Style Manager

Hello,
I have 38 CDialog, two CFileDialog and a couple of CPropertySheets and CPropertyPage classes which I would like to theme or change visual style when the parent frame switches styles when they are created by the parent frame.
I am considering using a templated decorator pattern to overwrite the OnPaint function for each Dialog created by the parent frame. Then I can get an instance of the current Visual Manager within the OnPaint call and draw the dialog and it's contents, if
necessary, based on the selected theme.
<decoratorpattern.png after verification>
Is there an easier approach to doing this?
Thank you, CodeMonkey1959, LegacyMFCExtensionLibrarySE

Hi CodeMonkey1959,
I think you need to create a base dialog class derive from CDialogEx and override the OnSelchangeVisualMngr function.
ON_CBN_SELCHANGE(IDC_VISUAL_MNGR, OnSelchangeVisualMngr)
Then create some new dialog class you want derive from thebase dialog class, so you can control all the dialog's visual style. You could look up to the sample of
DesktopAlertDemo in Visual C++ 2008 Feature Pack. Hope it helps.

Windows 8.1 Starting Virtual Switch Manager from VMM crashes VMM service

Started happening after tried to add external switch using WiFi.
Now, VSM shows 'Load Failed' for the switch. Immediately after stating s/w manager VMM service crashes. I am unable to add a new virtual switch.
Any help will be appreciated.
Thanks
Jas

Hi Jas,
>>Started happening after tried to add external switch using WiFi.
If it is only happen to creating external virtual switch bounding it to Wireless NIＣ, I would suggest you to delete all virtual switch then uninstall hyper-v role and update the driver for wireless NIC then install hyper-v again to check the result .
(By the way , in most of the cases external virtual switch bounding to wireless NIC will not work well as bounding it to wired NIC )
I would suggest you do not create external virtual switch bounding to wireless NIC .
If you want the VMs can access internet through host's wireless NIC please refer to following thread :

Any further information please feel free to let us know .

Cisco 3850 Switch Management Port - ACL on VTY

Hi,
I got these switches.
Switch Ports Model SW Version SW Image Mode
* 1 32 WS-C3850-24T 03.03.02SE cat3k_caa-universalk9 INSTALL
2 32 WS-C3850-24T 03.03.02SE cat3k_caa-universalk9 INSTALL
SSH access to Management port G0/0 with an ACL applied on line vty 0 4 is failing, even through the ACL is permiting traffic.
interface GigabitEthernet0/0
vrf forwarding Mgmt-vrf
ip address 172.16.12.3 255.255.255.0
negotiation auto
ip access-list standard ACLVTY
permit any log
line vty 0 4
access-class ACLVTY in
exec-timeout 15 0

history size 64
transport preferred ssh
transport input ssh
transport output telnet ssh
037599: *Mar 28 2014 04:59:49.919 AEDT: %SEC-6-IPACCESSLOGS: list permit-any permitted 172.16.12.100 1 packet
# show ip access-list permit-any
Standard IP access list permit-any
10 permit any log (3 matches)
If I remove the ACL under VTY "no access-class ACLVTY in", then SSH to the management port works. If I don't use the management port and use a normal port say G1/0/1 configured on management VLAN and assigned the same IP address, then SSH works with the VTY ACL still existing.
Any ideas ?
Thanks,
Rick.

Hi,
IOS will accept all VTY connections by default. However, if an access-class is used, the assumption is that connections should only arrive from the global VRF. If you need control the IP source while allowing VTY connections from VRF instances, you have a try configuration option "vrf-also"
So, you should get something like this:
line vty 0 4
access-class ACLVTY in vrf-also

Switch management access

Hello,
Cisco 3560 configured with management VLan10 ip 10.10.10.10 can be accessed via ssh, add new management interface VLan60 ip 10.10.60.10, also can access via ssh.
When I remove interface vlan 10, I can no longer access the switch, ip 10.10.60.10 is reachable, tried transport input to include telnet, same behavior.
What am I missing here?
Thanks

Brendan
Is this switch meant to be acting as a L2 switch or a L3 switch ?
If it is L2 then disable ip routing and use the default gateway you have already configured
if it is L3 then remove the default gateway and add a default route using the same next hop IP eg.
ip route 0.0.0.0 0.0.0.0 10.10.60.1

More likely than not the swicthes can be controlled using SNMP. Each manufacturer would have it's own MIB definition so a single general solution is very unlikely. You could define a switch object and use inheritance and dynamic dispatch to define a common API from your application's persepctive but will allow different implemenations specific to the switch. I have attached a basic SNMP library.

6509 issues - intervlan switch management

Okay, so we did a recovery on our 6509 last night which appeared to go well. I currently have 10 vlans on the 6509 all with seperate dist switches on each subnet...Now traffic across all subnets work fine except I no longer seem to be able to access my switch IPs anymore. Unless I am local to that subnet.
We did reboot the 6509 several times but none of the subnet switches were touched.
I tested one switch by rebooting and it appeared to fix the problem. Possible Arp cache problem ? Any thoughts ? I can reboot them all tonight but would like to know the cause..From the active MSFC I can ping all switch IPs, but not from the 6509 switch console.

Each floor is a Vlan which has a 3548 on it. The 3548 is trunked back to the 6509 via fiber and yes the uplink ports on the 6509 are trunked (isl).
The management IP of each 3548 is in the local subnet of the floor vlan..Ex.10.1.3.0 /24 is vlan 3 and the switch IP is 10.1.3.2. The trunk links back to the 6509 are working fine as all users per floor have connectivity out of their vlan. So each 3548 appears to be switching fine.
Thanks
Dave

Remote route and switch management

Good afternoon support community,
Does Cisco have a replacement for the 2811 console servers, newer with more features? I have been looking at opengear, but I wanted to know if Cisco had something equivalent to it. I'm looking for a way to manage devices via console, on a out of band network. If you have any recommendation please feel free to post them.
Thank you for your input.
Delmiro

There's not a direct replacement for the 2811 console server / router as far as I know.
Most customers I see are choosing either Opengear products or the Emerson (former Avocent, former Cyclades) ACS console servers. Link
