Problems connecting two stacks with fiber

I am having problems getting the 2 stacks to see each other with fiber. just your basic stacks, nothing fancy. Is there a line in the config that needs to be added? Fiber LED's are not lit.

Hi!
As you said the fiber LEDs are not lit, that means the ports are not 'up' so the stacking has not been done.
Log into your switches and then run the command 'Show int interface name' to know the status of the fiber ports.
Also check the connectivity of the stacking cables with the ports in the switch. Maybe you can take them out and then connect them again.
HTH, please rate the post if it does.

Connecting two 4510r with Fiber

I would like to connect two 4510r (50 Km separated) via FO but it doesn´t seem to support ZX FSPs and the supervisors don´t have GBIC slots. Any recommendations?

Two questions -
What Sup is in question?
Are you using this SFP( part number GLC-ZX-SM=) ?
This SFP seems to be supported by Sup IV and SuP V.
http://www.cisco.com/en/US/products/hw/switches/ps4324/products_data_sheets_list.html
Also check this link. The highlight being
"Cisco 1000BASE-ZX GBIC can reach up to 62 miles (100 km) by using dispersion shifted SMF or low-attenuation SMF; the distance depends on fiber quality, number of splices, and connectors."

Problem connecting two storage networks

Hello,
I connect two datacenters with 10GB modules. I'm using single mode fiber, it has 10Km between datacenters. Now I need connect the storage network in both datacenters using the same fiber. The storage networks use FCoE.
What solution can I use to connect the two storage networks. My budget is really limited.
Storage Network 1---------Network 1-------Fiber---------Network 2------Storage Network 2
Thanks for the help.

Brigid,
There seems to be two aspects:
One is to get the end points to coincide. You may tick View>Snap Guides, then click one path by the end Anchor Point and drag it to snap (Smart Guides say anchor when you are there).
The other is to get rid of the gap in the stroke(s), You may join the paths into one, dragging across the coinciding Anchor Points with the Direct Selection Tool and Ctrl/Cmd+J, or you may keep the separate paths and change the Cap to Round in the Stroke palette/panel which will give you a rounded outer appearance); I presume the former is what you wish, in which case you may choose between Round and Miter Join.

Problem connecting two seperate straight line paths. Please help!

Hi there, I'm new to illustrator and have been having a problem connecting two straight line paths. They never seem to line up correctly. Attached is a photo of the problem. I assume this is an easy fix but I can't figure it out myself.

Can connect two Macs with USB2 cable?

Can connect two Macs with USB2 cable?

You can connect two Macs with an ethernet wire, or conect two Macs using Firewire if one is placed in target disk mode, but that is it.

Can I connect two macs with thunder bolt ?

can i connect two macs with thunderbolt like I do with firewire and IP? I don't want to transfer files by using the control "T" at startup . I want use VNC to control one mac from the other and use thunderbolt vs ethernet.
thanks for any help

You can connect the two. Whether you can use VNC, I have no idea.

What happen when we connect Two PC with IP from Same subnets

Scenario 2nd : What happen when we connect Two PC with IP from Same subnets. PC1 -192.168.10.1/24 PC2 - 192.168.10.2 on a two different L2 Switch on different vlans which are connected via a LAN cable.
All ports are access ports
Interview Question : No More Info.
Pc1<SwA>------<SwB>PC2
Q.1 Will they communicate If yes what will be packet/frame flow.
Q.2 If not where will be the packet/frame drop. ? Why.
I need step by step if possible plz how the packet moves , vlan taggings n all internal works that happens behind .. plz
thnx in advnce ....

Hi Abhishesk,
The PCs should communicate each othet.
Since there is no trunk port involved, there is not tagging involved.
Since both the PCs are into the same subnet. PC1 will not need default gateway for the communication with PC2. So PC1 will start with sending ARP request for PC2 MAC address.
Since all the ports in SW1 are in same VLAN, the ARP should reach all ports including the switchport where SW2 is connected to.
Sw2 has got a complete different access port on ALL the switchports. Sw2 will receive the ARP from Sw1. Remember that there is no tagging for the frame. Hence Sw2 will again send the ARP packet to all the ports which belong to same VLAN wherein the packet is received. ie, Sw2 will send the ARP packet to all the ports in Sw2. PC2 will also get the the ARP.
The ARP reply will make it way back using the same logic.
Now both the PCs can start the actual packet exchange.

How do I correct the problem of two routers with the same OSPF Router IDs?

How do I correct the problem of two routers with the same OSPF Router IDs?

Hi,
The answer above is correct, though you don't really need to reload, you can just simply clear the OSPF process with the following command:
clear ip ospf 1 process

Connect 2 switch with fiber

Hi everybody,
I´m trying connect two catalyst 3560 Catalyst switch through fiber. I have a network in the office, it is working. Now, I need to take a switch in my office network (switch A) and add a new switch (switch B) for connect a near office. I have the same converter modulo in both extreme (finisar trj8519p1bnl-mc), I configured the switch B with Ethernet wire (from 10.0.0.1) and I put an IP within to office range IP (the same that others switch).
But when I connect the fiber in both switch port, the ports led are off. When I access to web interface from switch A, I can see the fiber port in yellow.
Somebody can help me?
Thanks!

Unsure if this is your issue, but many Cisco devices, by default, won't run non-Cisco optics. If not already doing so, you might try adding "service unsupported-transceiver" to your configuration.

Problem connecting two ipads to wifi

I'm sorry if this has been asked already. I'm having trouble connecting two ipads or an iPad and iPhone to my home wifi. Ive found that if I have an iPad or iPhone connected to my wifi, then i cant connect a second iPad at all. I have to turn the wifi setting off on the connected device, then I have to completely turn off the device I'm trying to connect, turn it back on, then it will accept the wifi password & connect. Long of the short, my friend and I can't use our ipads at the same time on my wifi. Is there a setting I could change on my router to fix this problem?

Or u cn try chk hw many ip address ur router was set to allocate.
Another router setting u cn try is set to WEP shared instead of WEP Open. I not sure if this solve, i set to WEP Shared bcos previous my nintendo DS only work with with WEP shared.
My home network is able to connect with 2 ipad and 2 iphs all at the same time, sometime with an additional laptop. Meeting 5 devices.

Problem connecting two trunks to sip provider using same CUBE

We need to connect two SIP trunks from service provider to Cisco CUCM 7.1 using CUBE “Cisco 2821”, SP using the following configuration:
First SIP PSTN Link Configuration(In-Out DID/DOD 218 7700 – 218 7799)
Customer IP Address =   10.196.191.158/30
SP IP Address = 10.196.191.157/30
Protocol= SIP
SIP Port = 5060
Transport Protocol=UDP
Voice Codec= G711 A-Law
DTMF = IN-Band DTMF without RFC2833
Signaling IP address = 10.201.20.49
IP Address 10.201.20.10 (Media IP) must be visible from IP PABX
Second SIP PSTN Link Configuration( Inbound Only 920009999)
Customer IP Address =   10.196.192.94/30
SP IP Address = 10.196.192.93/30
Protocol= SIP
SIP Port = 5060
Transport Protocol=UDP
Voice Codec= G711 A-Law
DTMF = IN-Band DTMF without RFC2833
SIP server IP address = 10.201.20.49
IP Address 10.201.20.10 (Media IP) must be visible from IP PABX
When we tried to configure both links on the same CUBE we faced two problems:
-          Routing issue, as we can’t route traffic using single CUBE through two different interfaces to the same destination “ i.e we have to configure static route commend (ip route 10.201.20.49 255.255.255.255 10.196.191.157 & ip route 10.201.20.49 255.255.255.255 10.196.192.93), sip traffic coming from one link can’t be sure to send it back to the same link.
-          SIP media & signaling control binding issue, as CUBE support sip binding using one interface only “one IP Address”, if we not using binding commands on the CUBE we can’t receive any calls though any link.
We have two options:
SP to send both traffic on the same trunk link
Or
Have another CUBE for the second link.
Attached network diagram.
Any solution?????

Ahmed Rizk

I didn't mean NAT CUCM, I meant the interface towards it. But since you're using a single interface then yes that is what you NAT. You have a lot going on in that config. Probably a lot more than you need. Like I said you should work on this in two legs. CUBE to ITSP, and then CUCM to CUBE. You're trying to make the whole thing work in one shot which is going to cause you some headaches.
Install XLite free version. In the account settings set your UserID to a generic 10 digit phone number, domain to something generic, then at the bottom set the Proxy Address to the IP of your CUBE. The media ports will be negotiated dynamically between the CUBE and the ITSP. Since you said you're not registering you will also need to give the ITSP YOUR peer IP (this is how they secure the trunk) which is whatever IP you're sourcing from when you leave your network (what you're NAT'ing the CUBE to).
For testing, reduce your config to something like this:
voice service voip
allow-connections sip to sip
allow-connections h323 to sip
no supplementary-service sip moved-temporarily
no supplementary-service sip refer
signaling forward none
sip
dial-peer voice 10 voip
description CUBE_TO_ITSP
session protocol sipv2
session target ipv4:SIGNALING IP PROVIDED BY ITSP
destination-pattern [2-9].........
codec g711ulaw
dtmf-relay rtp-nte sip-notify
no vad
dial-peer voice 20 voip
description ITSP_TO_CUBE
destination-pattern .
session protocol sipv2
session target ipv4:Eventually your CUCM IP...for now set it to your computers IP.
codec g711ulaw
dtmf-relay rtp-nte sip-notify
no vad
Use XLite to place a phone call from your PC (if you have a mic and speakers you can have audio if the call connects). This should come pretty close to getting your outward leg established. Once you get this part working you can add in more codecs and translation profiles if you want. Let me know what happens. Include any debug or packet cap results if you can.

Is it possible to directly connect two Xserves with a Promise VTrak E610fD via Fibre?

I have two Xserves and I'd like to connect them with a Promise VTrak E610fD. As this storage has two controllers, I'd like to connect both Xserve with both controllers. Is this setup possible? Can I access (read and write) the same disk array with both Xserves simultaneously (Xsan?) or do I have to create two separate arrays?

Hello bleistift, and welcome to the AppleBoards,
Fibre channel is SCSI which means that any device connected by fibre assumes it is in sole control of that device. When you attach more than one machine via fibre both machines assume they are in control and unexpected behaviors and data corruption ensues. SAN (like Apple's XSAN) provides a layer of arbitration over the shares allowing multiple fibre connections to play nicely with one another while still being connected over fibre.
You could easily connect two machines to a single RAID box if they are accessing different RAID volumes at the same time, but once you start connecting to the same data at the same time you need SAN.

Connect two G5 with 1000BASE-T (Gigabit) - how?

what i need to connect two G5 dual 1.8 with 1000BASE-T (Gigabit)?
just a cable or some cards and routers and ....?

Yeah, like tele_player said, it's a little harder if you want them to both have internet. We just set up our MDD and quad on a gigabit switch that so they can communicate with each other at gigabit speeds and then the switch was hooked up to a router for internet access. It wasn't that bad and we got all the supplies online for cheap. 50 foot sections of CAT 6 cost about $10. If you need to go through walls or anything like that, get the tool-less keystone jack connectors...they'll make your life much easier.

Problem Connecting Two Monitors

Just set up a new HP Mini 300-30 with two monitors. Monitor connection is through a device I bought that has HDMI cable connecting to back of HP Mini and two outlets on device to connect two monitors using VGA cables that came with each monitor. Monitors work but are set up with mirror image and I have not been able to find a way to make each monitor run indpendently. If I use keyboard and press Windows key + P it brings up a screen where I can select monitor options. I select the option to run separate monitors but nothing happens. I believe I have tried everything but the correct way.

Problems connecting IOS devices with new Comcast wireless cable modem?

Just installed a new cable modem from Comcast, it is their new high speed unit manufactured by Cisco. of the three IOS devices I've tried, all running currently the OS , are having problems connecting with the error "Unable to join the network " Home-XXXX" if you keep asking it may connect but I have to be persistant. My Devices are iPad 4 g Retna with 30pin connection, an iTouch ,latest model with camers, and current iPad mini. is it me or the modem?

You have probably already solved this issue, but I would hide the comcast wifi network (dont broadcast ssid) and make the password very hard. Make sure that put it on channel that does not conflict with your Airport Extream.
Connect the Comcast modem/router to the airport extream's wan port with an ethernet cable.
Comcast usually ships the DHCP enabled. Use the comcast DHCP server for your airport.
Configure the airport extream to "create a network" set the network to "bridge mode".
Name your network, broadcast the ssid all on the airport. Now all your devices will connect everytime. Use can use the Comcast "private" wireless network for maintenance, etc.
Just some thoughts... good luck
