Cisco Switching/Routing :: CAT 6509 STP Compatibility With F5 LTM
Sep 1, 2012
We have connected a single F5 box with dual links to 2 different Cisco Catalyst switches using 802.1Q trunks. F5 is configured with RSTP mode and on Cisco Switch RPVST+ is configured.STP root bridge is hardcoded on the Cisco side. Loop Guard is globally enabled.On F5 STP link type is Auto, STP Edge port is disabled since that port is connected to the cisco switch.When we are failing over the F5 primary link to the secondary link we see 'Loop Inconsistent' on the cisco switch and things dont work after the failover.We have tried configuring the F5 as STP passthrough but that doesn't fix out the issue.I have checked out the forums and found out following recommendations
1. Configuring MSTP bw F5 and Cisco for better compatibility (Not possible from Cisco side because of a major change in large production setup)
2. Configuring VSS in Cisco switches (not possible due to hardware limitation)
3. Connecting F5 using single links to each switch (redundancy compromised)
I am wondering that on which default vlan does the F5 STP instance0 sends the STP BPDUs ? the term used on Cisco side is native vlan and others use PVIDs; that F5 default vlan should match the native vlan on cisco trunk side.

I currently have a couple of 6509 chassis (router/switches) with the following hardware blades:
x3 48 ports
x1 NAM
x2 Sup720
Running 12.2(18)SXF3
I am keeping the four Sup720 modules and have purchased new versions of the others blades including two new 6509-E chassis?Can I take my stand-by Sup720 out of the production machine and insert it into the new chassis?

Are 887VAM-W-E-K9 and 800-IL-PM2 compatible? We have got both of them but it seems that router has a 30W power source and module has a 80W power source.

I have a WS-X6748-GE-TX with the WS-F6700-CFC daughter card. Is it possible to replace the WS-F6700-CFC daughter card with a WS-F6K-DFC4-AXL to make this compatible with the SUP-2T? Or, are there differences between the CFC and DFC base modules?

I've inherited a network. It looks to have been setup as 10/100 originally, using Netgear FSM726S switches with fibre connecting the switches. The fibre to copper conversion is mainly achieved with 10/100 media convertors rather than GBICs - not sure why - though there are some GBICs in use. Some of the "key" switches have been upgraded to Cisco Catalyst 2960G switches, but nothing else has been touched, so most of the network still runs at 100MB.

We are upgrading two standalone 6509E chassis to a VSS system with new VS-S720-10G-3C cards. The 6509's have WS-X6748-GE-TX card with DFC3B daughter cards (see below). The compatablity matrix (see below) states that 67xx cards are supported but it goes on to state DFC3C or DFC3CXL cards are needed. So does this mean that the existing WS-X6748-GE-TX cards have to be upgraded or will they be supported?

I have a Cisco 3825 router with a sfp module .(multi mode Cisco sfp ) connected to a Alcatel switch with fiberxon sfp. On a Cisco router the sfp card is been recognized and is seen when i used " show ip int brief " or show inventory commands. However the line protocol is down.
is their any compatibility issue with one side Cisco sfp and other side fiberxon sfp ? we have tested Cisco sfp -------Cisco sfp works fiberxon ----------------fiberxon works .

I would like to confirm if Cisco 3750 and 3750v2 can work in a stack? My Cisco 3750 is working on 12.2(37)se while 3750v2 is working on 12.2(50r)se.
I tried to configure the above on a same stack but seem to have compatibility issue and fail to work.

I am looking to see if Nexus 5596UP & Nexus 2248TP GE compatible with SFP-10G-SR? The reason is because a consultant was hired on to "design" the network layout and has decided to purchase Cisco SFP+ Copper Twinax Cables which have a 10M limit. A small handful of the Data Center racks are 10-15M away... just out of reach of the Twinax. I would prefer NOT to move the LAN row so that it is more centered in the room. Can I use the SFP-10G-SR to connect the 2 switches (5596 & 2248) together? This SFP has a 26M reach on standard 10gig fiber, the small cost increase per connection is of no concern.

I am getting conflicting info about this, and need to get confirmations.Is the older 6513 (non E) model compatible with WS-X6407-10GE blade?The switch we're getting this for have WS-SUP720-3B, 6000W power supply, and WS-C6K-13SLT-FAN2.From what I read they are compatible if entered in slot 9-13, but I also heard that 10GE modules are not compatible with the non E chassis.

I have a Cisco 3560 connected via fiber to a Nortel 1612G. The connection is up/up, the V LAN's on the switch work as needed, but I can not ping the switch from the Nortel, and as a result I can not remote into the Cisco for management. I see in the configuration for the trunk that it is configured for a native v LAN, but I don't see it defined which v LAN's are allowed, could this be the issue? I will provide some of the config information for the Cisco side, I understand the issue may be on the Nortel end but if the Cisco part looks OK?
Port config for the trunk:
interface GigabitEthernet0/49
description port_6_1612G
switch port trunk encapsulation dot1q
switch port trunk native v LAN 120
switch port mode trunk
Native v LAN config:
interface Vlan120ip address 172.16.120.11 255.255.255.128

can I plug power supply from 4500 to 6500? more specifically we have power supply PWR-C45-1300ACV. And we need to place some power supply to 6500, which has only one active module. So 1300 should be enough for it. But we dont know if they are physically compatible, if it is possible to plug. I didnt find this power supply to be officially?

I am new to Cisco networking (I just passed my A+ test and am working on my Network + test with an end goal to finish with a CCNP) and I bought a Cisco 2620 XM and a 1605R to figure out how to setup and practice on. In my house we have Verizon Fios with the standard Verizon appliance feeding internet to the rest of the house. My question is that will my Cisco appliances be usable with an out connection from the Verizon appliance? I am concerned because the connection that comes into my room from the Verizon router would be considered a LAN connection, not a WAN? Also in order to configure the router, I believe it needs an RJ-45 to serial to plug into a computer for setting up. My computer doesn't have a serial port so will an RJ-45 to USB work (since that is serial as well)?

I am confused about some things regarding the different IOS versions and their compatibility with certain switch hardware. I understand the differences between the IPBASE and IPSERVICES ios but am not quite clear as to how you can tell which ios images will work on which Cisco switch model platforms, other than the fact that some switches are designed only to run the IPBASE images and others have advanced hardware to run the advanced images. For instance, if I have a 3750-24TS-E with an IPBASE ios on it, can I load an IPSERVICES ios that came from say a 3750G-24TS-E1U? whether the ios on one platform can be transferred to another?

Does GLC-GE-100FX is supported on the WS-C2960S-24TD-L. I don't see this switch listed under the compatibiilty matrix.URL,But the datasheet for the 2960S says this:"The Cisco Catalyst 2960-S with SFP+ does not support the GLC-FE-100BX, GLC-FE-100FX, or GLC-FE-100LX."But it provides no reference for the GLC-GE-100FX,The easy answer is, no the 2960S-24TD doesn't support it.

I want to connect a Cisco small business switch (sf302-8) to a Cisco catalyst 2960S over a multi mode fiber. The transceiver I am using in the catalyst is a GLC-SX-MM. I presume in the SF302, I will have to use a MGBSX1. My question is "are these transceiver compatible with each other and if not, is there a transceiver that will suit both pieces of hardware?

I've 4500 Core Switch with 4507R chassis, Sup V-10GE(WS-X4516-10GE) along with 2 WS-X4306-GB line Cards, but now I require a line card for 14 more fiber up links and I cannot go with 3 of 4306 as there are only 2 slots left. I've checked and found that E series line cards does not work with Sup V Engine.
As per the link below, I found that "WS-X4448-GB-SFP" is compatible..

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 ?
