Precautions prior to reload the core switch of my fabrics

Hello,
I recently bought Gen 4 8-Gbps FC advanced modules for my 9509. I've updated the 9509 to NX-OS 5.2(2). It is indicated in the release notes that after the update, the 9509 need to be reloaded in order to support the Gen 4 modules.
I have a 2 fabrics SAN with core/edge topology. Of course my 9509 are the core switches of my fabrics. They are running the lower priority (1) for every VSANs.
Here the fcdomain info of a VSAN (they have all the same configurations)
VSAN 2
The local switch is the Principal Switch.
Local switch run time information:
       State: Stable
       Local switch WWN:   20:02:00:0d:ec:35:73:81
       Running fabric name: 20:02:00:0d:ec:35:73:81
       Running priority: 1
       Current domain ID: 0xe9(233)
Local switch configuration information:
       State: Enabled
       FCID persistence: Enabled
        Auto-reconfiguration: Disabled
       Contiguous-allocation: Disabled
       Configured fabric name: 20:01:00:05:30:00:28:df
       Optimize Mode: Disabled
       Configured priority: 1
       Configured domain ID: 0xe9(233) (preferred)
Principal switch run time information:
       Running priority: 1
Interface               Role         RCF-reject
port-channel 1     Downstream       Disabled
port-channel 2     Downstream       Disabled
Now, I'm not sure if they are other important points that need to be checked prior to the reload. I do guess that the FCID will not change after the reload and the switch will come back as principal also.
If other configurations need to be verified, feel free to tell me which one.
Thank you in advance.

I 150% agree with dwb and woodmeister50 about WD hard drives. They are NOWHERE near the quality they should be. When you can get a Seagate for just a few dollars more, and they last years longer, NO ONE should buy a WD. I lost $25,000 worth of music and audiobooks on a six-week-old WD in 2007 and that was the last I'd ever buy from them. They REFUSED to warranty it with the ORIGINAL sales receipt from Bestbuy.
I have 16Gb of Crucial RAM in my Mini and here's what I've discovered.
You WON'T see "lightning fast" performance increases, becasue the Mini is pretty darned fast to begin with. What you WILL see is that when you're running RAM intensive apps like Photoshop or Parallels, other apps won't "bog down".
Quite frequently I find myself with less than half a gig of free RAM out of that 16. When it was only 8 I was at 100% nearly ALL THE TIME. When I only had the 4 it came with, it was always maxed out.

Activating zoneset only from the core switch

Folks,
How can i restrict so that only the core switch is allowed to make changes to the active zoneset?
Also if I am merging two switches and they have active zonesets but with different names, would that merge the two fabrics?
Thanks,
Tarun

your probably thinking about NPV, NPV is disruptive but NPIV isn't. It is just a feature that you would enable on the core.
The acronyms are confusing and easily mixed up.
NPIV allows multiple initiators to login over a single FC/port-channel. NPV changes the operation of the switch so that to the core it looks like a host with a lot of initiators/HBAs. In NPV mode the edge switch doesn't consume any FC domain IDs.

Confused the CORE Switch's

HI!
PS Throw Light to the following SCenario:
I Have 5 distribution switchs(6509-sup20) connected to Core switch 6509-sup20.the routing protocole its EIGRP.I SENT THE Following Network as a summary to the CORE:
DS1)10.11.0.0:
DS2)10.12.0.0:
DS3:10.13.0.0:
DS4:10.14.0.0:
DS5:10.15.0.0:
Now maybe these confused the core switch.what is the OPTIMUM Way to uncofused the core?& let the core always function properly as well as very good performance
i waiting ur reply!

Under the EIGRP process, the network statement should only include subnets that you want to advertised FROM the router. Subnets that are learned from other devices need NOT to be listed.
If you issue
'sh ip interface brief'
on the core, you can select what networks you want to advertise FROM the core to all devices sharing the same EIGRP AS.
For instance, if the 'sh ip int bri' includes the following networks:
172.16.1.1
192.168.1.1
10.1.1.1
Then your EIGRP process should be like
router eigrp 10
network 172.16.1.0
network 192.168.1.0
network 10.1.1.0
You can also use another method if you have multiple subnets that are within the major network, for instance:
10.11.0.0
10.12.0.0
10.13.0.0
10.14.0.0
could be represented with a single command
router eigrp 10
network 10.0.0.0
no auto-summary.
It will advertise the subnets listed above and not the 10.0.0.0 network because 'no auto-summary' is also part of the EIGRP process.
now if you have the following connected networks:
10.11.0.0 thru 10.14.0.0 AND 10.50.0.0 thru 10.60.0.0 but only want to advertise the 10.11.0.0 thru 10.14.0.0 network then the EIGRP process would be like
router eigrp 10
network 10.8.0.0 0.0.7.255
no auto-summary

My page has a button that, when clicked, calls a Java function that sets a PageLegend and changes an image but then FireFox reloads the page switching everything back to original values. What's up?

This is happening with an ASP page. Not sure when it started, but the page used to work fine. The Java script is listed in the troubleshooting section. The button calls nextPic() which calls showPic(). After nextPic processes the page is reloaded.

Connecting core switch to the internet ?

Hi,
We have 2 6506's connected through an ether-channel trunk.
On these 6506's we have configured a vlan, vlan interface and 2 access ports for 2 ASA's.
These ASA's run in failover mode but only one ASA is physically connected at the moment.
We want to be more resilient so our provider has provided us with a redundant setup of routers for our internet connection.
However, for this construction they would need a layer 2 connection on our side to have HSRP running.
There are 2 options in my opinion :
- Buy a set of switches to facilitate the layer-2 connection between te routers and to connect the outside of the ASA's.
- Instead of buying 2 new switches, create a new unrouted vlan on our core 6506's and use access-ports for the routers and the ASA's.
But how safe is it to connected the core switch with an unrouted vlan to the internet router ?
In terms of vlan hopping or other possible attacks ?
I think i have to disable DTP, Spanning-Tree, CDP and maybe a lot more ?

I am as far as applying this to secure the port :
switchport
switchport mode access
switchport access vlan X
switchport nonegotiate
spanning-tree bpdufilter enable
spanning-tree portfast edge
switchport port-security
switchport port-security maximum 3
switchport port-security violation restrict
no cdp enable
Any additions to this ?

Core switch and sub switch gateway

I have a Layer 3 core switch(backbone) 10.18.16.0/24, and the core switch needs to connect to multiple Layer 2 sub switches.
The Layer 2 sub switches will connect to multiple workstations. The sub switches network will be 172.20.10.0/24, 172.20.40/24 and so on.
I use core switch IP 10.18.16.11 to connect to sub switch 172.20.10.0/24. Which gateway IP should I use for 172.20.10.0/24 ? Should I use 172.20.10.1 or 10.18.16.11 ?
Thank you for your help in advance.

I am not sure what you mean by "sup switches", but usually you need a management IP/vlan segment, so you can use it to access the devices. So if your management segment is 172.20.10.0/24 you assign an SVI to every layer-2 switch and give it an IP in this range and the gateway for all the SVIs should be on the core (172.20.10.1/24
example:
access switch-1 172.20.10.11/24
access switch-2 172.20.10.12/24
access switch-3 172.20.10.13/24
and so on
The default gateway for all your layer-2 switches should be the SVI on the core (172.20.10.1/24)

Core switches experience High CPU while generating syslog report from LMS

Hi Everyone,
Are there anyone who experience that the CPU utilization of some devices went up while generating a report from RME. Basing from other monitoring tool SNMP is taking up a huge cpu process. Any idea why this happened considering that the report is generated daily but only on one instance it caused the core switches to be paralyze due to high cpu. Changing the SNMP community string is the immediate action that resolve the issue to disconnect it from LMS.
BTW, this is LMS 2.6.
Thank you.

The problem did not reoccurred any more. When I checked on the Syslogcollector.log it appeared that it is unable to subscribe. I assumed that the reason why snmp packets were flooded during the time that it they experience high cpu is because the client is generating syslog report for all devices while the syslog collector is not subscribe. Is this possible?
Thanks

Hyper-v cluster with core switch downtime... what to do?

Is there a way to essentially "pause" the hyper-v cluster and keep things running but do NOT attempt to failover anything for any reason?
We have one Procurve 5412zl switch with two c7000 enclosures. In each c7000 enclosure there are two switches that connect all the blade servers within the enclosure. Those two switches are interconnected internally so they can communicate within the enclosure.
So if the core switch goes down the hyper-v servers in the same c7000 enclosure can still communicate but they will be seperated from the others in the other enclosure.
So we have 4 hyper-v servers in one enclosure and 3 in another. If i disconnect the core switch i'm wondering what will happen (if I reboot the switch which is what I need to do).
How can I avoid having to shut down everything for this and just tell hyper-v cluster to not do anything when the network is lost?

Hi Quadrantids,
" to essentially "pause" the hyper-v cluster and keep things running but
do NOT attempt to failover anything for any reason"
Based on my understanding you need to keep cluster running on the same C7000 enclosure , in another words before you cut the connection between the C7000 enclosures you may migrate VMs to same enclosure to keep running (I assume that the
storage will not be affected by the restart ).

Whenever I access my Hotmail inbox to open a new mail it starts reloading the mail after every second unless i switch it to full view?

whenever I access my Hotmail inbox to open a new mail it starts reloading the mail after every second unless i switch it to full view. Kindly help me to solve this continuous problem.

I confirm this is a known bug and Microsoft are working on a fix. They plan to fix this before Firefox 4 reaches release candidate phase.
A workaround is to change a preference in Firefox:
# Type '''about:config''' into the location bar and press enter
# Accept the warning message that appears, you will be taken to a list of preferences
# Locate the preference '''html5.enable''' and double-click on it to change its value to '''false'''
If you do this, remember to set the preference back to true by double-clicking on it again when Firefox 4 release candidate is made available, the bug should be fixed by then.

Route or switch on the core Layer

I am working on a new network design for my company with four buildings, I have used building distribution method for all buildings, my design seems to be functioning properly, I have configured vlans and eigrp routing on the distribution switches as you can see on the diagram, but used the four core layer switches just for switching not routing and I did not configure any routing on them, I would like to know if this is good design or do I need to configure routing on the Core Layer as well

There is no right or wrong answer to this. Originally the recommendation was to switch in the core ie. use only L2 because L2 switching as fast and L3 routing was slow. But then L3 switches appreared and the recommendation was to use L3 to connect to the core.
But both are just recommendations. You don't have to follow the guidelines slavishly.
Having said that, looking at your design there are a lot of redundant paths between switches. This means lots of loops and using L2 will mean blocked paths in the core and potentially blocked paths to and from the core. If you used L3 connections from the distrbution to the core and between the cores you would be able to utilise all the links and hence get more bandwidth.
In addition if a link failed you would not be reliant on STP to bring up a redundant path as all paths would be in use (although you should still run STP).
Couple of other points -
1) you have 4 switches in the core - what is the reasoning behind this ? is it distance limitations between buildings ?
2) your addressing. Ideally you would want to be able to summarise from one building to the other so it would make more sense to have all the 192.168.x.x networks in one building and all the 10.x.x.x networks in the other. Actually it would make more sense to decide on an IP range ie. 10.x.x.x or 192.168.x.x (not both) and then use summarised ranges for each building.

Sinkhole routing rfc1918 on the core/distribution switch (6500)

Hi guys,
I am planning on getting rid of packets going to unrouted nonexistent rfc1918 networks in our DC environment going into internet facing firewall from our core/distribution switch via default route. I am thinking on setting a bunch of rfc1918 static routes to Null0 on the core/distro switches so they will kill all the packets destined to unused rfc1918 networks into Null0. Wondering if that would be a good solution to this.
Thanks!

I am not sure quite what you have in mind when you talk about a bunch of rfc1918 static routes. I could see doing a route for 10.0.0.0 range, for 172.16.0.0 range, and for 192.168.0.0 range. Is 3 a bunch? If you had more in mind what would they be?
If you do static routes to Null0 for the summarized spaces then it would allow routing to any private addresses used inside your network to work since they should have more specific entries in your routing table and it would discard traffic with destination addresses in private address space. Be aware that if you have any site to site VPN tunnels from the firewall or any address translations on the firewall that use private addresses that your plan may very well have negative consequences for them.

Looking for the list of maintaining and configuring tasks on Core switch.

I have some experiences DMS switches, things like setting up zone, alias, zoneset etc, but never have any experiences on core switches or something between core and edge switches since the SAN environment here has not reached that scale.
Would you please list those tasks that needs to be done in daily maintenance, and required configurations? or some related documents? including those on core switches or something between core and edge switches?
Thank you very much for your ideas.

Hello ciscomagic1,
The definition of core and edge swicthes in a FC architecture is related the topology point of view.
The core could be NPIV enabled switche and all edges running as NPV mode.
Also the core could be the switch that will make the translation of FC to another protocol as FCoE, FCIP or iSCSI and should be licensed to those protocols.
Normally the core is the more centralized switch in the entire fabric, with more backplane capacity, redundancy and high port density. Of course this is not a rule at all.
Essentially the core and edge switches can perform the same tasks and have the same functionality, the point is how them will be better availed in a design.

AF:InlineFrame reloads again while switching the tabs

Hi All,
I have a SOC on my page and a panel tab with 2 tabs. On selection of a value in SOC i populate some details in first tab and second tab contains an inlineFrame which shows PDF accordingly. Now on every selection of value in SOC I have to open/disclose the first tab. For this i bind 2 tab components with bean and set disclosed of first tab to TRUE and other to FALSE and applied addPartialTarget to both. But when PDF tab is open by user and he tries to select a value again from SOC, this disclose thing doesn't work and infact Inline Frame starts reloading the PDF again. I am not able to understand how can i STOP this behavior of Inline-frame.
Please help.
JDEV-11.6

Check this blog post to see how to properly disclose tabs: Decompiling ADF Binaries: Programmatically disclosing a ShowDetailItem in a &lt;af:panelTabbed&gt;
You can't stop inline frame reload because this will automatically happen if his position in page DOM structure is changed(for example, when you disclose tab).
So if you want to avoid inline frame refresh then you need to use some other container(maybe af:navigationPane with af:commandNavigationItem) and show/hide your components by using javascript.

Can I use DHCP snooping and IOS DHCP server on the same switch stack

Hello,
I am shortly going to be deploying a Cisco CallManager solution for a customer whose network comprises stacks of Catalyst 3850 switches.
There is no separate core/server farm switch so the CallManager servers, voice gateways and IP phones will all plug into the same stack and be in the same VLAN (not my choice!).
For security we want to enable DHCP snooping and were planning on using the IOS DHCP server on the Catalyst switch stack.
Will this work? - when I enable DHCP snooping in networks with separate access layer switches I set the uplinks to the core as trusted links.
I am not sure whether DHCP snooping will work in this case. Do I need to set the VLAN interface on the switch as trusted, is this even possible?
Unfortunately I do not have access to a layer 3 switch to test this at the moment.
Thanks

Nope. That's the issue.
They'll sync on a third device acting as a hotspot, but the device sending a signal is not "on" the network it creates so the airport is all by itself on that network. At least that is what it looks like to me. Anyone have another take on it? Seems pretty silly that an iPad can put out a wifi signal, an Airport Express can receive a wifi signal, and yet there is no simple way to get them to communicate under this particular condition.

When I click on link in a website firefox randomly decide to reload the page after it has already loaded it once. It's really irritating. I tried uninstalling firefox and installing the latest version but it still does it. HELP!!!!

After I updated to 3.6.8 I started noticing on a game I play at UniversalCriminal.com that randomly when I click on a link, firefox will load the appropriate page and as soon as it finishes loading that page it will refresh or reload the same page. It doesn't happen on any particular link it just happens randomly, and not all the time but most of the time. I tried reverting back to an earlier version of firefox but it still happened. I uninstalled firefox and reinstalled the latest version but it still happens. It doesn't do it with IE or Chrome or Opera. What gives? Any ideas anyone?

I see that you ave changed some network.http prefs. 
Doing that can cause all kinds of problems because not all servers like such changes, so you can try to reset those prefs on the about:config page. 
network.http.max-connections 48 
network.http.max-connections-per-server 16 
network.http.max-persistent-connections-per-proxy 16 
network.http.max-persistent-connections-per-server 8 
network.http.pipelining true 
network.http.pipelining.firstrequest true 
network.http.pipelining.maxrequests 8 
network.http.proxy.pipelining true 
network.http.request.max-start-delay 0
