The command "disconnect ssh vty 2" worked for me, under the console and could not go into enable mode. Saved a reboot of a CAT 6500-VSS.

Greetings,
I have been asked to deploy a pair of 8861's and have them SSL VPN back to the CME. I recall with the 7975, it had to terminate on an ASA and I am assuming this is still true but please correct me if I am wrong. Also I would like to know if there are any special considerations with regards to traffic SIP and or SCCP between the 8861 and the CME/CUE once the SSL is up.
I have been unsuccessful with locating a guide or document regarding this spacific product.
Cheers,
-michael

In L3 mode the control and packet networks are not officially used however I have run into issues if they are not avalible its a bit odd with Cisco. When you change managment VLAN for the VSM you will disrupt communications between the VSM and vCenter as they communicate over their respective managment IP addresses. If your vCenter is in the samve VLAN as your VSM managment IP you will need to change the VLAN access for both. Are you planning to change the IP address of the VSM or just the VLAN? If you are simply moving the VLAN only then once you move the route point from the old VLAN to the new VLAN everything should connect back up. Again traffic will flow even if VSM and vCenter can not communicate, you just cant make configuration changes. Again I am one who ares on the side of caution and would do this after hours on in a maintinace window.

It looks as if your VSM is already operating in L3 mode and that will make things a bit easier. You should find a port profile in your VSM that has a command 'capability l3control'. This command basically tells the VSM that it should listen for l3 control traffic from the VEM's on that VLAN/port-profile. Do the ESX hosts live in the same VLAN as the VSM managment interface? If the l3control command is on the port profile that the ESX hosts are attached and you are not changing their IP or VLAN then you should not have to change anything there. Be sure to add the new VLAN to your uplink profiles or your VSA uplink trunks if your running trunking. You may also want to consult with TAC as they can give you more precise information and assistance.

I had a feeling that the VSAN was not allowed to pass. If you look at the port channel configuration you will see the allowed VSAN configured. The reason you got the errors before was that you can not apply configurations to the interface if its a channel member. It has to be made the channel interface that intern makes the change to the interface its self. Glad it worked out for you. Please be sure to make this as answered.

I agree with Steven. If you dont allow the VSAN over the trunk between the switches then you FC traffic cannot flow similar to a regular data VLAN. Also is there are reason you have 6 trunks are they all betweent he 2 switches? If so you may want to consider placing them into a port-channel.

Do you have a FC trunk between the 2 switches or do you have a direct connection between the 2 switches on the VSAN? If not that is likely the issue. Do you show FLOGI for the 2 devices on the respective switches? Either of these things could be causing your issue. Also don't forget about the FCping command to help troubleshoot as well. Hope this helps. Sent from Cisco Technical Support iPad App

I actually had to change the management VLAN and IP of a live production VSM with complete success. However I strongly advise migration everything back to standard VM switching as a precaution. It should be noted in my configuration the VSM and VEM are operating in L3 mode. If you are just changing the VLAN ID then the VEM and VSM will not communicate properly until the changes are completed however the VEMs will keep passing traffic. You will not be able to make configuration changes to the ESX cluster or VM networking. Make sure to update the system VLAN with the new ID on the uplinks. The VEM and VSM initial communications need the correct system VLANs to be declared. If you are going this route you may want to consider changing over to L3 mode. Cisco is moving away from the L2 designs, also L3 mode is default in the newer version of code. Hope this helps. Sent from Cisco Technical Support iPad App

If your route point is a router or L3 switch then you could configure a route-map with an ACL that is used to change the next hop ip for the servers in the DC to the DRC. This will be a lot of manual configuration and testing but it maybe a viable solution. Sent from Cisco Technical Support iPad App

I have seen this issue with a red hat server that was configured with a bond mode 5. In my instance the Ethernet interfaces are being used are attached to VFCs to support FCoE and can not be members of an ether-channel. So it was up to the server to make the LACP channel decision. I would get the same error referencing the VIP of the bond jumping between the 2 physical interfaces. Note the VIP MAC address will be the same as the physical address of the first NIC of the bond. The ultimate workaround was to set the bond to mode 1 active/passive interfaces. Don't know if this would help in your case but it maybe worth testing. Hope this helps.

Hello You should verify that the HBA has initialized. I have experienced this similar issue with Qlogic cards, basically right out of the box you have to enter into the card during boot and actually turn on FCoE. The Qlogic gives the ability to connect and test the SAN connection over FC in its BIOS. Please note that sometimes a cold reboot of the server is needed before flogi appears. You can issue the sho int vfc , also show flogi data. You will hopefully see the cards PWWN and the vfc interface number. This is based on my experience with dell and hp using Qlogic CNAs.

Greetings Everyone, I am having an issue with an ACS unit that has been in service for about a year. It was setup by a contractor to hook into AD. I am not that familiar with it it but the issue is we added a new network tech that is a member of the correct AD group. How ever when the user attempts to login he is denied and I see an error in the ACS log stating "unknow user or password in external DB" or something to that effect. I looked into the configurations for the external DB and it shows no agent status. I guess my question is are there agents that need to be installed on the DC or is there something else I need to check? One other think my account was in place at the time the ACS was installed and I have never had an issue with logging in. Its almost like the ACS does not know that a new user was created and or not syncronizing to the AD. Any help would be appreciated mike

Greetings, Sorry for the long delay. I did want to pass along the solution to my problem and maybe it will help someone else. Working with TAC it was discovered that the issue was a combination or missing configurations, not having ports 3-6 configured for the Control and Packet VLAN along with the VSM file being present on one unit but not the other. Not sure how that happened but it did. Also accourding to TAC there is some kind of BUG that can raise its ugly head in the newest version of software for the 1010 that causes this "split brain" issue. Ultimatly I reinstalled the OS to the constant rebooting node and made sure that the configurations on the unit that was active were correct. Once that was done it booted and came right up.
