View 1 Replies View RelatedCisco Switching/Routing :: Location Of FIB And Adjacency Table In Both 6500 Series And Fixed Ports Switches
Apr 28, 2012I 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.

Cisco Switching/Routing :: 4948E / EIGRP Implementation With GLBP
Sep 4, 2012I'm in the process to install two 4948E switches. I will be configuring GLBP and wanted to get some guidelines on configuring GLBP and EIGRP:
- First question is like HSRP I'm configuring it on both swithches like this:
Switch 1:
interface vlan 5
ip address 10.1.5.249 255.255.255.0
glbp 5 ip 10.1.5.1
glbp 5 priority 110
glbp 5 preempt
glbp 5 authentication md5 key-string xxxxxx
[code]....
- Second question is about EIGRP, when I configure EIGRP on the main switch that is AVG with the following commands, will I also have to run the same commands on the second 4948 E too?
router eigrp 10
network 10.1.5.0 255.255.255.0

Cisco Switching/Routing :: 3640 GLBP Working Now Want Interface Redundancy?
Dec 6, 2011So I have 2 routers (cisco 3640) that each go to their own ISP and then back to the same switch. I have setup ospf and glbp, and now have pretty good redundancy. If either internet connection or routers go down everything is still golden.
So I was thinking that if an interface went down then the router would not be load balanced with glbp which got me thinking whats the best way to get interface redundancy (and I was going to add a 2nd switch with the second interface).
1) Setup BVI on the 2 interfaces.
2) Setup a 2nd interfaces (on each router), I would have to split the subnet, for instance: [code]then the machines could be on the subnet 192.168.0. 0/23 and setup glbp for 1 ip across all 4 interfaces (I'm not even sure if you can do this but think it would work).
3) Is there a way to utilize etherchannel or anything like this
A negative to option 2 would be that if 1 of the interfaces went down, all the sudden 2/3 (or so) of your traffic would be going through 1 router.
Cisco Switching/Routing :: 3845 / 3640 - GLBP - Weighting Based On Bandwidth For One PPP Of Many?
Dec 28, 2011I have two routers at our core data center, a 3845 and a 3640. These are configured with GLBP. There are 4 remote sites:
Site #1: One T1 link to the 3825
Site #2: One T1 link to the 3825, and One T1 link to the 3640
Site #3: One T1 link to the 3825, and One T1 link to the 3640
Site #4: One fractional T1 link to the 3825, and One T1 link to the 3640.
My question regards site #4. If i understand correctly, GLBP works on the premise of "host" balancing, and not true "load" balancing. The reason I ask is that the large majority of our WAN traffic is from our Exchange server to our remote sites. In the case of site #4, our exchange server is sending traffic on the fractional T1. Is there any way with GLBP to either split this traffic from a particular host across two links in a round-robin fashion, but leave other hosts to travel wherever the router sends them, or, to force at least our exchange server to use the full T1, rather than the fractional?
I've read up on the weighting mechanism, and it appears that tracking an interface has nothing to do with bandwidth use. If I understand correctly, if I were to track the Site #4 PPP to the 3640, and give a weight of 10 to glbp on there, it would really only take affect if the interface is down. It will have nothing to do with host AVF election.For the record, exchange traffic is constant to this site, so there is no chance for the host connection to reset and potentially elect to use the larger pipe. I would like to "tweak" this to make better use of available bandwidth.

View 5 Replies View RelatedCisco Switching/Routing :: 6509 VSS Implementation / Migration?
Jan 5, 2012I am planning an implementation of VSS on our two 6509 switches, and would like some feedback on things to look out for, and any issues encountered by others that have done this already.
We have the 10Gig port installed on the Management blades, but not configured yet.
Main questions would be:
1: What kind of "down time" am I looking at for the migration? (Reboots, configuration reloads, etc.)
2: I will be saving the configurations on both devices before-hand, but how does the VSS migration "merge" the configurations of both devices?
3: L2 VLANS - we have some on one switch, others on the second switch. Will these be combined, or would this be a manual process?
Any other things of note that I should know about before planning this migration?
Cisco Switching/Routing :: 6509 / HSRP Migration To VSS With 0 Downtime?
Mar 13, 2012I have to migrate two Cat6K series switches in a Data center to the new Cisco 6509 Series switches with no downtime. i know there are few threads on the same topic but none of them discuss about the downtime.The two Old Cat6K series switches are working in HSRP redundant mode. All access/Dist switches are dual homed to these two switches in downlink direction. In the uplink direction a router is dual homed to both Switches. Now my requirement is to completely migrate the configuration from the old switches to the new one in VSS mode without any downtime. Already VTP server is running on of the old switches so VLAN migration is not an issue. I will update the network diagram in few hours .As per now i am going to follow these steps:
1. Remove active links from switch 1 and shut it down
2. Monitor network and traffic impact on switch 2
3. Install the new 6509 switch along with switch 2 (VSS config already done in Staging)
4. Config HSRP and make it standby
5. Connect all removed links back to new switch
6. Remove old switch 2 and monitor network
7. Connect new switch with VSS config
8. Connect the two new switches together in VSS and move virtual IP to SVI.
During last step i think i will face some minor packet drops.
Cisco Switching/Routing :: 6509 To 6513 Migration Required
Jan 9, 2012We currently run 1 Cisco 6509 (CatOS) for our production network. It has multiple vlans which feed distribution switches on each floor in 2 buildings. Essentially each floor is its own vlan. Each floor switch is connected back to the 6509 via fiber connections. We also have several production vlans that our VMware and AIX environments connect to.
I would like to phase out the the 6509 and replace it with a new 6513 chassis, sup720's etc. Currently it is sitting next to the 6509 in the rack. I need to limit downtime as much as possible but can get one shutdown window over a weekend. However I dont think it would be enough time to move all of the existing etherconnections etc etc
So I am looking to run them both at the same time and slowly migrate over to the 6513 over the next few months.My solution was to use the 6513 (IOS) in L2 mode only for now and trunk it back to the 6509 via 4 1 gig connections in a LACP config.
So the 6509 would still be handling all of the L3 routing for now.Once I had moved all of the fiber and ethernet connections over to the 6513, I would use the shutdown weekend to configure the 6513 for L3 and essentially turn off the 6509 at that point.
My questions are
- Is there a better way to do this ?
- By trunking the 6513 to the 6509 do I need to worry about any loop issues ?
- I am aware of the oversubscription issue for the port channel and have spread the 4 interfaces over the different groups of asics.

Cisco Switching/Routing :: L3 Routing With Catalyst 4900 Series?
Mar 19, 2013I have peculiar challenge ahead of me and would like to get new perspectives.
The objective is to route specific VLAN traffic and the caveat is that I have multiple VLANs with the same network address.
For example:
VLAN100 10.10.10.0/28 VLAN101 10.10.11.0/28 VLAN102 10.10.12.0/28
VLAN103 10.10.12.0/28
VLAN104 10.10.11.0/28
I need traffic going from VLAN100 with a destination of 10.10.11.0 forwarded to VLAN101 and NOT VLAN104.
This task is currently being completed by a multi context firewall and we're trying to decommission the asset.
Cisco Switching/Routing :: 6500 / Restricting Inter-VLAN Routing?
May 9, 2013I'm looking to restrict Inter-VLAN routing through L3 switch (cisco 6500) and wanted to know best possible way to do it. I used VACL and achieved success to some extent, but my config is making clients take up to 5-6 mins to authenticate IP address from the DNS (bootps).My VACL config was as follows:
Subnet to restrict is 10.100.15.0 (VLAN 15)
STEP 1: Created extended ACL to allow bootpc/bootps through DNS
ip access-list extended EACL_DNS
permit udp any eq bootps any
permit udp any eq bootpc any
STEP 2: Created standard ACLs to allow only relevant subnet, server VLANs & some IPs from other subnets for printers/scanners etc.
ip access-list standard SACL_VLAN_15
permit 10.100.15.0 0.0.0.255 (the subnet I'm restricting)
permit 10.100.50.0 0.0.0.255 (server VLANs)
permit 10.100.25.45 0.0.0.0 (printer in another VLAN which has to have access in VLAN 15)
STEP 3: Created VLAN access list
vlan access-map VACL_15 10
match ip address EACL_DNS
action forward
vlan access-map VACL_15 20
match ip address SACL_15
action forward
STEP 4: Applying VLAN Access list on VLAN 15 vlan filter VACL_15 vlan-list 15 Though the above works, below is noted:
1. I'm still able to PING 10.100.15.2 (the switch virtual interface) from outside the subnet, which I don't intend to do so. Howeve all cients in the subnet have no connectivity from outside the VLAN 15.
2. As mentioned its taking quiet some time to negotiate with the DNS server at system boot time.

Cisco Wireless :: Remove WiSM2 From Catalyst 6500 Series Switch?
Jul 21, 2012how to safely remove the WiSM2 from the Catalyst 6500 series switch? According to the documentation "Catalyst 6500 Series Wireless Services Module 2 Installation and Verification Note":
To remove the WiSM2, perform these steps:
Step1 Shut down the module by one of these methods: In privileged mode from the router prompt, enter the hw-mod module mod shutdown command. NoteIf you enter this command to shut down the module, you must enter the following commands in global configuration mode to restart (power down, and then power up) the module: Router# no power enable module modRouter# power enable module mod If the module does not respond to any commands, press the SHUTDOWN button located on the front panel of the module.
Step2 Verify that the WiSM2 shuts down. Do not remove the module from the switch until the POWER LEDis off.
But, in the case of Step1 (1st methods) I do not see a option "shutdown" in the command "hw-mod module 3"...
All I prompted to enter is: c6500#hw-module module 3 ?
boot Specify boot options for the module through Power Management Bus control register
reset Reset specified component
simulate Simulate options for the module Is it hidden options?
IOS version of c6500 is 12.2(33)SXJ1
In the case of Step2 (2nd methods) there is not any button on the front panel of the module?
And yet, it is better to remove the module configuration manually or use the command module clear-config prior to removing the module?

1 time per day, always at the same time, the router stops working. for both wired and wireless connections. i need to unplug the router to work. The modem and ooma continue to work, so i know there is internet getting passed from the modem to the ooma. However, the internet gets disruptted with the routers.
this must be a settings issue with the router. where everyday at the same time, maybe when timewarner changes over or something the router does not pick it up?? i dont know. i have gone through 2 routers and same identical problem.
