Cisco Switching/Routing :: Location Of FIB And Adjacency Table In Both 6500 Series And Fixed Ports Switches
Apr 28, 2012
I am little confused about the location of FIB table and adjacency table in both cisco 6500 series and fixed ports switches .In case of 6500 series switches
"Central CEF mode:The CEF FIB and adjacency tables reside on the route processor,and the route processor performs the express forwarding. Use this CEF mode when line cards are not available for CEF switching, or when features are not compatible with distributed CEF."
If line cards do no support CEF, then FIB and adjacency tables are built and are located on route processor( control plane ). Data plane operations are implemented in software and route processor performs those operations.
Some Cisco switches actually use different hardware to control the different planes. For example, the Cisco Catalyst 6500 is a modular switch that uses the Multilayer Switch.Feature Card (MSFC) for control-plane operations, and the supervisor Policy Feature Card (PFC) for the data-plane operations.
Supervisor module has has MSFC and PFC. MSFC implements control plane operation where as PFC implements data plane operation.But the first paragraph says in Central cef mode, both data plane and control plane operations are implemented by route processor. [code]
Do these switches implement the Central mode cef in same way as mentioned above. i.e
"Central CEF mode:The CEF FIB and adjacency tables reside on the route processor and the route processor performs the express forwarding. Use this CEF mode whenline cards are not available for CEF switching, or when features are not compatible with distributed CEF."Or fixed ports switches such as 3750 implement data plane operation in hardware where FIB tabe and adjacency table are maintained on Data plane.

My task is to upgrade a couple of 6500 series switches, 6513 with SUP720/MSFC3 (WS-SUP720) and Policy Feature Card 3 (WS-F6K-PFC3B) installed. How to upgrade those switches if in SSO redundancy mode with two SUPs installed?
I understand that it is good to connect to the MSFC3 via console and upgrade this first, is this correct?
I also have to upgrade some 6509 but I only can test it on one 6509-E, how to get everything up to date. [code]

some of the features of 6500 are enabled by default and woudn't appear in the "Show run". See the command below and how do I make sure whether these featues are enabled by default or not. Would it appear in the config if enabled?
ip verify unicast source reachable-via rx
ip verify unicast source reachable-via any
storm-control broadcast level 70
what are the difference between the commands below and can they be enabled together.
spanning-tree guard root
vs
spanning-tree loopguard default
vs
spanning-tree guard loop

We want to configure the "mac-address-table synchronize" command on our 6500 series switches to ensure that the CAM tables on our DFCs are in synch with the PFC on the supervisor modules. url...it is recommended that we disable the routed MAC purging with the mac-address-table aging-time 0 routed-mac global configuration command. What is a routed mac entry? Are there any issues with running that mac aging-time command?
We also plan to run this command "mac-address-table aging-time 14400" to keep our ARP and CAM tables on the same aging time to reduce unicast flooding on our network. Can we run this command with the "routed-mac" command above?

We are getting log messages like
%EARL-DFC4-4-NF_USAGE: Current Netflow Table Utilization is 95%
%EARL-DFC4-4-NF_USAGE: Current Netflow Table Utilization is 99%
What this messages really means and how to get rid of these messages. We are using IOS version 12.2(33)SXJ in Catalyst 6500.

For intervlan routing, Is 'IP routing' command enabled by default on a 6500 series switches based on the IOS?and on 3750 switches, do we need to enable the "ip routing" command manually for intervlan routing?

I have a routed interface on a Cisco 6500 Series switch. I am trying to find a way to adjust the tcp mss.To date I have not yet been able to find a way to accomplish this. Is this just not supported?

I am getting the below messages on my Cisco 6500 series switches every 1min. The IOS version is 12.2(33)SXI6 & with SUP32-GE-3B
%ILPOWER-7-DETECT: Interface Fa1/1: Power Device detected: Cisco PD
%ILPOWER-7-DETECT: Interface Fa1/1: Power Device detected: Cisco PD
%ILPOWER-7-DETECT: Interface Fa1/1: Power Device detected: Cisco PD
These messages are I am recieving on few ports only not on all port having IP Phone connected. I tried changing the phone to some other model but that also did not resolved my problem. Also I tried powering on the phone using power adapter but the issue still persist.
Client are not facing any issues due to this error, but still I would like know what can be the issue which is generating these logs.

I had a question on spanned ports - if i was to add another additional port with the command:
monitor session 10 destination interface Fa2/22
will this take out the existing monitoring configuration below? Will I have to add the whole line in including the interface - will this cause any disruption to existing traffic being spanned to those ports?
monitor session 10 source interface Fa2/3 - 5 , Fa2/8
monitor session 10 destination interface Fa2/2 , Fa2/33
#show mon
Session 10

What are the rough figures that a NPE-G2 is able to hold for the BGP routing table?
378475 network entries using 51472600 bytes of memory 378482 path entries using 21194992 bytes of memory 63008/63003 BGP path/bestpath attribute entries using 8065024 bytes of memory BGP using 82975730 total bytes of memory
Are these 3 memories different memory allocated or are they are a sub-set of each other? If a NPE-G2 has 1GB RAM, does it mean that the routing table limit is depending on the RAM availability?

I have a Cisco Catalyst 2960 series switch. When I connect another switch or a VMWare Esx server on one of the ports, the port blinks for few seconds and then goes off. When I connect a desktop or laptop or a windows server the ports stay led and I can access resources on the network. However, when connect another switch or a vmware esx server, the port is disabled.
What config in the switch can I check to make sure the ports stay on regardless when I connect a desktop / laptop, switch or vmware server?

On a number of 6500 chassis it appears that linecard 3 did exist at somepoint, but was removed.Problem is that when issuing the 'show int desc' or 'show ip int brie' the ports for the still appear, and indeed same with 'show run' and 'show conf'.

Is there any challenge to upgrade core switch 6500 series from Nexus 7009 which runs NxOS, because i have 3750X series switches connected at distribution and access layer in my network topology??
Is there any challenge if we place NxOS in core and IOS in distribution and Access layer??? how we are able to match sh run config in existing 6500 switch to Nexus 7009 NXOS?

I've been looking into IGMP snooping and have read that a L2 switch will forward multicast traffic to all ports connected to an interested receiver AND all mrouter ports. In a L2 'V' topology this results in all multicast traffic routed onto a VLAN being forwarded to the 2nd distribution switch. My question is how should a 6500 Sup720 deal with this unwanted multicast traffic? Both a Local SPAN of the RP and a Netdr capture suggest that this traffic is punted to the RP and ultimately dropped. Is this expected behavior or should the traffic be dropped in H/W?

we have cisco 6500 series switch and configured port channel on both switches with 2 gig interfaces on both switches.
When we enable the port channel mode to as desirable to the interfaces on both side and applied the port channel to physical interfaces switch will go down and if we remove on any one side switch will come up. we have enabled globally the following commands. [code]

We have two 6500 switches and I am unable to login to these switches anymore, but i was able to connect to them yesterday via Telnet. The strange part is that it happened for both switches at the same time.But now when i try to login, it gives me a message "password required, but none set". I can login to them via console.Is it because the 0 - 4 VTY connection are being used and there is no password set from VTY 5 to 15?The config has not changed.
SWITCH-1
line con 0
exec-timeout 0 0
password xxxxx
login
line vty 0 4

we are using cisco 6509 series switches as core switches. and Cisco 4510,4507 series switches as edge switches. all the vlans are created at core switches and propogating to edge switches through VTP. we are using OSPF as routing protocol at core switch for internal routing. till now we are using 4510,4507 switches as layer 2 switches. Since, 4510 & 4507 switches are hign end swithces i want use them as layer 3 switches instead of layer 2.if i change these switches from layer 2 to layer 3 does it make any impact on our network or better to keep them as layer 2 switches.if i change these switches to layer 3 is there any advantage i will have.

We are implementing NAC in our environment and unfortunately still some of our obsolete 6500 switches are running CATOS, the current (cat6000-sup2cvk9.8-6-4.bin) image does not support some of the commands related to NAC implementation. Therefore, I would like to urge you to provide me the 8.7 image which supports all the NAC related commands and will be easier to finish the long pending assignment.
We are in process of replacing the obselete hardware but that will take time.
So, 8.7 K9 CATOS image required.

I am connecting power cable (series power cables) on 3750 stacks. i have connected them the same way the stack cables are connected i.e. fo rexample on a stack with 3 3750s:
1- fitst slot on fist switch connected the second slot last switch in the stack.
2- second slot/ port on the first switch to the first on second and seoncd on teh second switch to first on the third switch.
this how they are alway been stacked.Now, I need to connect power cables and I have followed the same method for stacks up to 4 switches. it seems that if a stack has more tham 4 switches, then the cabling will be dofferent!?I was wondering what will be on the cabling scheme for stacks more than 4 switches.

OSPF normally only comes with IPservices image and not IP Base image. The 3560-C series data sheet says that it only suport IP Base image, yet it mentions that support for OSPF in included. Are there any restictions in the OSPF support?.
