Maybe I can explain better:
I've got a Cisco 6509 with 4 configured vlan interfaces
Int Vlan 10 10.10.1.0/24
Int Vlan 20 10.10.2.0/24
Int Vlan 30 10.10.3.0/24
Int Vlan 40 10.10.4.0/24
Vlan "10" is the phone voip Vlan and it must not talk with the others Vlan. The others Vlan can comunicate normally except with Vlan "10".
Pratically Vlan "10" needs to be isolated from the others.
This equirement comes becouse Vlan 10 is wireless and has the WEP key encryption (very weak protocol). Some Phone couldn't support the WPA2 key and I need to avoid an unauthorized external client, cracking the WEP key and connecting to this WiFi, could have free access to the others Vlan.
After a abrupt power cylce of 6509 switch, vlan configuration got missing. Switch has not crashed.

Upgraded the IOS in Cisco 6509 switch, Configured Port profiling , MAC Pinning , HBA Cards to UCS / Nexus 1000V Infrastructure. After this change they lost the connectivity to UCS and HP Serers. Every tower is checking at their end.
The Network Team has reverted back the core switch with old IOS , but still the problem persisit.I could only see the following error log in the core switch. There are two port-channels one between core 1 and core 2. The other is between core switch and FWSM module. [code]
I need to setup a vlan between the 6509 and 2621 router. This needs to be a VLAN (200) the runs between the devices that uses DOT1Q trunking. The end result is all the networks (vlans) on the 6509 can talk to the LAN on the 2600 (10.133.22.0 / 23) and visa versa.

I'm working at a company that has several 6509 switches running CatOS. They have two of the 6509's running in vtp server mode and the rest as clients. I set up a new vlan from one of the vtp servers and it propagated out. The problem comes when I try to assign a port on one of the vtp clients to this new vlan. It gives me an error that the switch must be in vtp server mode to add/delete vlans. I'm not trying to add/or delete a vlan just trying to add a port into an existing vlan. I'm hesitant to put the switch in vtp server mode. Is this a CatOS thing or is there a specific command to accomplish this?

I'd like to do this by changing the native vlan on the trunk port on the core 6509 interface that connects to the 3560. and leave the management vlan on the 3560 as vlan 1.
Seems trivial but what I tried didn't work and I didn't have the window to troubleshoot. I'll paste the simplified configs for the interfaces below

We have a problem with CDP packets on sent by our Cisco 6509's. Unlike our other Cisco switches (4948G, 5020, etc.), the 6509 tags administrative traffic on the native vlan. As a result the CDP packets are sent with an 802.1Q header with a tag of 1. The other switches send the CDP packets untagged on the native vlan. This causes problems because we have non-Cisco devices in our lab that also receive and send CDP, but they do not process the packets that are tagged by the 6509. They see the packets from the 4948 and 5020 just fine.
How can I disable the administrative native vlan tagging on the 6509? Here is the current setup:
nwkdev-6509-1#show vlan dot1q tag native
dot1q native vlan tagging is disabled globally

We have a pair of 6509 working in a VSS configuration (IOS 12.2(33)SX5). The 6509s connect to a pair of ASAs (7.2 code) running in an Active/Standby setup. These ASAs in turn connect to routers going to remote sites. I have configured Netflow on the following VLANS,
VLAN 10 - Servers Vlan
VLAN 9 - Transit/ASA VLAN (connects ASAs to 6509s). All traffic originating from any VLAN on the 6509 crosses this VLAN in order to reach remote sites and vice versa
I configured the netflow source VLAN 11 although I am not collecing any netflow from it.Although I have been getting lots of Netflow info, I noticed that netflow for traffic originating from any user VLAN on the 6509s going to any remote site via TRANSIT/ASA VLAN(9) does not get reported, I even tested with 4 GB traffic but no result. Only reverse traffic (i.e. from remote site to user VLAN) is reported as it traverses the Transit VLAN (9).
I read somewhere that egress netflow is not supported in 6500, but isnt traffic originating from a user vlan to a remote site via the transit VLAN (9) considered ingress with respect to the transit VLAN (9)? I would like to know whether bidirectional Netflow is supported on 6500 VLANS. I have mimimum control on routers beyond the ASAs, and since these ASAs run 7.2 code netflow is not supported, and Monitoring this Transit Vlan gives me extremely useful info.
I do get netflow biderectional traffic from the Server Vlan 10, but I think it is correlated by the netflow collector from vlans 9 and 10. [code]
I am getting very slow window file transfer speed (4 Mbps per second) between two connecting servers in Cisco 6509 switch.

we've had an issue with our network, we have 2 6509 connected with redundancy, which are connected with 2 x 4900 Switches, from which are connected to a ESX Chassis for visualization, the thing is that the ESX stopped working, and the 4900 switches, and the main core were suffering from overload, they hang on it very well, in order to stop the overload, one of the links to the ESX Chassis were disconnected from one of the 4900 switches. The CPU usage from the 4900 and the core(6509) went down below 40%, and then they started to migrate the virtual servers from the chassis to another 2 chassis that were added right after. They were actually working well, but suddenly the 6509 changed to the other supervisor after everything was OK. We were wondering what could have been the cause of this, maybe the virtual servers migrations, maybe the overload from the ESX ? We also had a few question, is there any need to reload the cores every few months as a planned task ? Because the cores have been up for more than 1 year. And also is there any kind of of tool to monitor the CPU status, or the status overall from the cores or the switches ?

Activity description : We had planned migration of these devices into a new Datacenter, it was a planned activity. During migration of devices from one Dc to a new DC we broke the VSS and kept the primary running and removed the secondary switch and migrated this secondary to new DC and powered this device ON in the new DC and checked all the config was very much fine but this device was OFF network as secondary was brought to new DC just to limit the downtime during the primary switch movement.
During the activity ( Primary switch movement )We powered off the Primary switch and mean time before shifting into new Data center We had brought up secondary switch which was already existing in the DC was put live in the network and it was working fine without any issues.
Later we had moved Primary into new data center and tried to put into VSS with the secondary , during this period the secondary device into went into RECOVERY MODE and primary device was not responding and devices went off network and immediatly we removed the VSL link and brought up primary into production network without secondary online in the network ( Without VSS just stand alone switch ) network started working, but bringing up the primary we found that some of the VLANS in the FWSM was deleted and some VLAN had misconfiguration ( example : say original VLAN ip 10.200.112.1 has become 10.300.13.1 ) also some of the access list as well as SVI was deleted making configuration mismatch.
Wanted to know while syncronization b/n primary and secondary switch in VSS if we pull out VSL link would create this type of issues.
I have problems in my Cisco network until I connected some Moxa devices.This Moxa are models EDS-316 and EDS-208
My principal trouble is the traffic UDP. Suddently the network don't permit the traffic UDP in VLAN where are connected Moxa devices.
During an hour the Moxa can send TCP traffic, but can't send UDP. If a Moxa device is unplugged from network, all devices connected to him can work offile from principal network, but if I plugg again the Moxa is like disable.
After one hour (more or less) the system restart all functions and work fine.I catch the logs from TXerrorsInPorts and all the ports where is connected a Moxa have errors all time.
I don't know which is the problem, but I think that problem is in negotiation from Moxa to Cisco.This is the configuration from a port where is connected a Moxa: [code]

We currently have RIP2 running between and the switchs and each 4500 is managing its own VLANs.The IPTV uses IGMP snooping and multicasting to broadcast the video feed. The problem that came up is that the we cannot configure a gatewar for the setup boxs for the IPTV system. They will only work on a single VLAN and they are spread all over the network.Can we configure only this VLAN to be propagated over our RIP network???
